# Python scripts for simulating QM, part 0: A general update

My proposed paper on my new approach to QM was not accepted at the international conference where I had sent my abstract. (For context, see the post before the last, here [^] ).

“Thank God,” that’s what I actually felt when I received this piece of news, “I can now immediately proceed to procrastinate on writing the full-length paper, and also, simultaneously, un-procrastinate on writing some programs in Python.”

So far, I have written several small and simple code-snippets. All of these were for the usual (text-book) cases; all in only $1D$. Here in this post, I will mention specifically which ones…

Time-independent Schrodinger equation (TISE):

Here, I’ve implemented a couple of scripts, one for finding the eigen-vectors and -values for a particle in a box (with both zero and arbitrarily specified potentials) and another one for the quantum simple harmonic oscillator.

These were written not with the shooting method (which is the method used in the article by Rhett Allain for the Wired magazine [^]) but with the matrix method. … Yes, I have gone past the stage of writing all the numerical analysis algorithm in original, all by myself. These days, I directly use Python libraries wherever available, e.g., NumPy’s LinAlg methods. That’s why, I preferred the matrix method. … My code was not written from scratch; it was based on Cooper’s code “qp_se_matrix”, here [PDF ^]).

Time-dependent Schrodinger equation (TDSE):

Here, I tried out a couple of scripts.

The first one was more or less a straightforward porting of Ian Cooper’s program “se_fdtd” [PDF ^] from the original MatLab to Python. The second one was James Nagel’s Python program (written in 2007 (!) and hosted as a SciPy CookBook tutorial, here [^]). Both follow essentially the same scheme.

Initially, I found this scheme to be a bit odd to follow. Here is what it does.

It starts out by replacing the complex-valued Schrodinger equation with a pair of real-valued (time-dependent) equations. That was perfectly OK by me. It was their discretization which I found to be a bit peculiar. The discretization scheme here is second-order in both space and time, and yet it involves explicit time-stepping. That’s peculiar, so let me write a detailed note below (in part, for my own reference later on).

Also note: Though both Cooper and Nagel implement essentially the same method, Nagel’s program is written in Python, and so, it is easier to discuss (because the array-indexing is 0-based). For this reason, I might make a direct reference only to Nagel’s program even though it is to be understood that the same scheme is found implemented also by Cooper.

A note on the method implemented by Nagel (and also by Cooper):

What happens here is that like the usual Crank-Nicolson (CN) algorithm for the diffusion equation, this scheme too puts the half-integer time-steps to use (so as to have a second-order approximation for the first-order derivative, that of time). However, in the present scheme, the half-integer time-steps turn out to be not entirely fictitious (the way they are, in the usual CN method for the single real-valued diffusion equation). Instead, all of the half-integer instants are fully real here in the sense that they do enter the final discretized equations for the time-stepping.

The way that comes to happen is this: There are two real-valued equations to solve here, coupled to each other—one each for the real and imaginary parts. Since both the equations have to be solved at each time-step, what this method does is to take advantage of that already existing splitting of the time-step, and implements a scheme that is staggered in time. (Note, this scheme is not staggered in space, as in the usual CFD codes; it is staggered only in time.) Thus, since it is staggered and explicit, even the finite-difference quantities that are defined only at the half-integer time-steps, also get directly involved in the calculations. How precisely does that happen?

The scheme defines, allocates memory storage for, and computationally evaluates the equation for the real part, but this computation occurs only at the full-integer instants ($n = 0, 1, 2, \dots$). Similarly, this scheme also defines, allocates memory for, and computationally evaluates the equation for the imaginary part; however, this computation occurs only at the half-integer instants ($n = 1/2, 1+1/2, 2+1/2, \dots$). The particulars are as follows:

The initial condition (IC) being specified is, in general, complex-valued. The real part of this IC is set into a space-wide array defined for the instant $n$; here, $n = 0$. Then, the imaginary part of the same IC is set into a separate array which is defined nominally for a different instant: $n+1/2$. Thus, even if both parts of the IC are specified at $t = 0$, the numerical procedure treats the imaginary part as if it was set into the system only at the instant $n = 1/2$.

Given this initial set-up, the actual time-evolution proceeds as follows:

• The real-part already available at $n$ is used in evaluating the “future” imaginary part—the one at $n+1/2$
• The imaginary part thus found at $n+1/2$ is used, in turn, for evaluating the “future” real part—the one at $n+1$.

At this point that you are allowed to say: lather, wash, repeat… Figure out exactly how. In particular, notice how the simulation must proceed in integer number of pairs of computational steps; how the imaginary part is only nominally (i.e. only computationally) distant in time from its corresponding real part.

Thus, overall, the discretization of the space part is pretty straight-forward here: the second-order derivative (the Laplacian) is replaced by the usual second-order finite difference approximation. However, for the time-part, what this scheme does is both similar to, and different from, the usual Crank-Nicolson scheme.

Like the CN scheme, the present scheme also uses the half-integer time-levels, and thus manages to become a second-order scheme for the time-axis too (not just space), even if the actual time interval for each time-step remains, exactly as in the CN, only $\Delta t$, not $2\Delta t$.

However, unlike the CN scheme, this scheme still remains explicit. That’s right. No matrix equation is being solved at any time-step. You just zip through the update equations.

Naturally, the zipping through comes with a “cost”: The very scheme itself comes equipped with a stability criterion; it is not unconditionally stable (the way CN is). In fact, the stability criterion now refers to half of the time-interval, not full, and thus, it is a bit even more restrictive as to how big the time-step ($\Delta t$) can be given a certain granularity of the space-discretization ($\Delta x$). … I don’t know, but guess that this is how they handle the first-order time derivatives in the FDTD method (finite difference time domain). May be the physics of their problems itself is such that they can get away with coarser grids without being physically too inaccurate, who knows…

Other aspects of the codes by Nagel and Cooper:

For the initial condition, both Cooper and Nagel begin with a “pulse” of a cosine function that is modulated to have the envelop of the Gaussian. In both their codes, the pulse is placed in the middle, and they both terminate the simulation when it reaches an end of the finite domain. I didn’t like this aspect of an arbitrary termination of the simulation.

However, I am still learning the ropes for numerically handling the complex-valued Schrodinger equation. In any case, I am not sure if I’ve got good enough a handle on the FDTD-like aspects of it. In particular, as of now, I am left wondering:

What if I have a second-order scheme for the first-order derivative of time, but if it comes with only fictitious half-integer time-steps (the way it does, in the usual Crank-Nicolson method for the real-valued diffusion equation)? In other words: What if I continue to have a second-order scheme for time, and yet, my scheme does not use leap-frogging? In still other words: What if I define both the real and imaginary parts at the same integer time-steps $n = 0, 1, 2, 3, \dots$ so that, in both cases, their values at the instant $n$ are directly fed into both their values at $n+1$?

In a way, this scheme seems simpler, in that no leap-frogging is involved. However, notice that it would also be an implicit scheme. I would have to solve two matrix-equations at each time-step. But then, I could perhaps get away with a larger time-step than what Nagel or Cooper use. What do you think? Is checker-board patterning (the main reason why we at all use staggered grids in CFD) an issue here—in time evolution? But isn’t the unconditional stability too good to leave aside without even trying? And isn’t the time-axis just one-way (unlike the space-axis that has BCs at both ends)? … I don’t know…

PBCs and ABCs:

Even as I was (and am) still grappling with the above-mentioned issue, I also wanted to make some immediate progress on the front of not having to terminate the simulation (once the pulse reached one of the ends of the domain).

So, instead of working right from the beginning with a (literally) complex Schrodinger equation, I decided to first model the simple (real-valued) diffusion equation, and to implement the PBCs (periodic boundary conditions) for it. I did.

My code seems to work, because the integral of the dependent variable (i.e., the total quantity of the diffusing quantity present in the entire domain—one with the topology of a ring) does seem to stay constant—as is promised by the Crank-Nicolson scheme. The integral stays “numerically the same” (within a small tolerance) even if obviously, there are now fluxes at both the ends. (An initial condition of a symmetrical saw-tooth profile defined between $y = 0.0$ and $y = 1.0$, does come to asymptotically approach the horizontal straight-line at $y = 0.5$. That is what happens at run-time, so obviously, the scheme seems to handle the fluxes right.)

Anyway, I don’t always write everything from the scratch; I am a great believer in lifting codes already written by others (with attribution, of course :)). Thus, while thus searching on the ‘net for some already existing resources on numerically modeling the Schrodinger equation (preferably with code!), I also ran into some papers on the simulation of SE using ABCs (i.e., the absorbing boundary conditions). I was not sure, however, if I should implement the ABCs immediately…

As of today, I think that I am going to try and graduate from the transient diffusion equation (with the CN scheme and PBCs), to a trial of the implicit TDSE without leap-frogging, as outlined above. The only question is whether I should throw in the PBCs to go with that or the ABCs. Or, may be, neither, and just keep pinning the  $\Psi$ values for the end- and ghost-nodes down to $0$, thereby effectively putting the entire simulation inside an infinite box?

At this point of time, I am tempted to try out the last. Thus, I think that I would rather first explore the staggering vs. non-staggering issue for a pulse in an infinite box, and understand it better, before proceeding to implement either the PBCs or the ABCs. Of course, I still have to think more about it… But hey, as I said, I am now in a mood of implementing, not of contemplating.

Why not upload the programs right away?

BTW, all these programs (TISE with matrix method, TDSE on the lines of Nagel/Cooper’s codes, transient DE with PBCs, etc.) are still in a fluid state, and so, I am not going to post them immediately here (though over a period of time, I sure would).

The reason for not posting the code runs something like this: Sometimes, I use the Python range objects for indexing. (I saw this goodie in Nagel’s code.) At other times, I don’t. But even when I don’t use the range objects, I anyway am tempted to revise the code so as to have them (for a better run-time efficiency).

Similarly, for the CN method, when it comes to solving the matrix equation at each time-step, I am still not using the TDMA (the Thomas algorithm) or even just sparse matrices. Instead, right now, I am allocating the entire $N \times N$ sized matrices, and am directly using NumPy’s LinAlg’s solve() function on these biggies. No, the computational load doesn’t show up; after all, I anyway have to use a 0.1 second pause in between the rendering passes, and the biggest matrices I tried were only $1001 \times 1001$ in size. (Remember, this is just a $1D$ simulation.) Even then, I am tempted a bit to improve the efficiency. For these and similar reasons, some or the other tweaking is still going on in all the programs. That’s why, I won’t be uploading them right away.

Anything else about my new approach, like delivering a seminar or so? Any news from the Indian physicists?

I had already contacted a couple of physics professors from India, both from Pune: one, about 1.5 years ago, and another, within the last 6 months. Both these times, I offered to become a co-guide for some computational physics projects to be done by their PG/UG students or so. Both times (what else?) there was absolutely no reply to my emails. … If they were to respond, we could have together progressed further on simulating my approach. … I have always been “open” about it.

The above-mentioned experience is precisely similar to how there have been no replies when I wrote to some other professors of physics, i.e., when I offered to conduct a seminar (covering my new approach) in their departments. Particularly, from the young IISER Pune professor whom I had written. … Oh yes, BTW, there has been one more physicist who I contacted recently for a seminar (within the last month). Once again, there has been no reply. (This professor is known to enjoy hospitality abroad as an Indian, and also use my taxpayer’s money for research while in India.)

No, the issue is not whether the emails I write using my Yahoo! account go into their span folder—or something like that. That would be too innocuous a cause, and too easy to deal with—every one has a mobile-phone these days. But I know these (Indian) physicists. Their behaviour remains exactly the same even if I write my emails using a respectable academic email ID (my employers’, complete with a .edu domain). This was my experience in 2016, and it repeated again in 2017.

The bottom-line is this: If you are an engineer and if you write to these Indian physicists, there is almost a guarantee that your emails will go into a black-hole. They will not reply to you even if you yourself have a PhD, and are a Full Professor of engineering (even if only on an ad-hoc basis), and have studied and worked abroad, and even if your blog is followed internationally. So long as you are engineer, and mention QM, the Indian physicists simply shut themselves off.

However, there is a trick to get them to reply you. Their behavior does temporarily change when you put some impressive guy in your cc-field (e.g., some professor friend of yours from some IIT). In this case, they sometimes do reply your first email. However, soon after that initial shaking of hands, they somehow go back to their true core; they shut themselves off.

And this is what invariably happens with all of them—no matter what other Indian bloggers might have led you to believe.

There must be some systemic reasons for such behavior, you say? Here, I will offer a couple of relevant observations.

Systemically speaking, Indian physicists, taken as a group (and leaving any possible rarest of the rare exceptions aside), all fall into one band: (i) The first commonality is that they all are government employees. (ii) The second commonality they all tend to be leftists (or, heavily leftists). (iii) The third commonality is they (by and large) share is that they had lower (or far lower) competitive scores in the entrance examinations at the gateway points like XII, GATE/JAM, etc.

The first factor typically means that they know that no one is going to ask them why they didn’t reply (even to people like with my background). The second factor typically means that they don’t want to give you any mileage, not even just a plain academic respect, if you are not already one of “them”. The third factor typically means that they simply don’t have the very intellectual means to understand or judge anything you say if it is original—i.e., if it is not based on some work of someone from abroad. In plain words: they are incompetent. (That in part is the reason whenever I run into a competent Indian physicist, it is both a surprise and a pleasure. To drop a couple of names: Prof. Kanhere (now retired) from UoP (now SPPU), and Prof. Waghmare of JNCASR. … But leaving aside this minuscule minority, and coming to the rest of the herd: the less said, the better.)

In short, Indian physicists all fall into a band. And they all are very classical—no tunneling is possible. Not with these Indian physicists. (The trends, I guess, are similar all over the world. Yet, I definitely can say that Indians are worse, far worse, than people from the advanced, Western, countries.)

Anyway, as far as the path through the simulations goes, since no help is going to come from these government servants (regarded as physicists by foreigners), I now realized that I have to get going about it—simulations for my new approach—entirely on my own. If necessary, from the basic of the basics. … And that’s how I got going with these programs.

Are these programs going to provide a peek into my new approach?

No, none of these programs I talked about in this post is going to be very directly helpful for simulations related to my new approach. The programs I wrote thus far are all very, very standard (simplest UG text-book level) stuff. If resolving QM riddles were that easy, any number of people would have done it already.

… So, the programs I wrote over the last couple of weeks are nothing but just a beginning. I have to cover a lot of distance. It may take months, perhaps even a year or so. But I intend to keep working at it. At least in an off and on manner. I have no choice.

And, at least currently, I am going about it at a fairly good speed.

For the same reason, expect no further blogging for another 2–3 weeks or so.

But one thing is for certain. As soon as my paper on my new approach (to be written after running the simulations) gets written, I am going to quit QM. The field does not hold any further interest to me.

Coming to you: If you still wish to know more about my new approach before the paper gets written, then you convince these Indian professors of physics to arrange for my seminar. Or, else…

… What else? Simple! You. Just. Wait.

[Or see me in person if you would be visiting India. As I said, I have always been “open” from my side, and I continue to remain so.]

# WEF, Institutions, Media and Credibility

Some time ago, I had run into some Internet coverage about some WEF (World Economic Forum) report about institutions and their credibility rankings. I no longer remember where I had seen it mentioned, but the fact that such an article had appeared, had somehow stayed in the mind.

Today, in order to locate the source, I googled using the strings “WEF”, “Credibility” and “Media”. The following are a few links I got as a result of these searches. In each case, I first give the source organization, then the title of the article they published, and finally, the URL. Please note, all cover essentially the same story.

• Edelman, “2017 Edelman TRUST BAROMETER Reveals Global Implosion of Trust,” [^]
• Quartz, “The results are in: Nobody trusts anyone anymore,” [^]
• PostCard, “Must read! World Economic Forum releases survey on Indian media, the results are shameful!,” [^]
• TrollIndianPolitics, “`INDIAN MEDIA 2ND MOST UNTRUSTED INSTITUTION’ Reports WORLD ECONOMIC FORUM,” [^]
• Financial Express, “WEF Report: ‘India most trusted nation in terms of institutions’,” [^]
• Financial Times, “Public trust in media at all time low, research shows,” [^]
• WEF, “Why credibility is the future of journalism,” [^]

“Same hotel, two different prices…” … [Sorry, just couldn’t resist it!]

Oh, BTW, I gather that the report says that institutions in India are more credible as compared to those in Singapore.

Do click the links if you haven’t yet done so, already. [No, I don’t get paid for the clicks on the outgoing links.]

Still getting settled in the new job and the city. Some stuff still is to be moved. But guess it was time to slip in at least a short post. So there. Take care and bye for now.

# Miscellaneous: my job situation, the Tatas, and taking a break…

This year’s Diwali isn’t going great for me. I am still jobless—without reason or rhyme. It is difficult to enjoy Diwali against that backdrop.

As you know, engineering colleges affiliated to the Savitribai Phule Pune University (SPPU for short) have been telling me that my Metallurgy+Mechanical background isn’t acceptable, even though the rules have changed to the contrary, and say that I now qualify (in my interpretation).

Recently I attended an interview, and it seems like I may be able to obtain a clear-cut answer on my eligibility (i.e. the equivalence of Metallurgy and Mechanical) from SPPU.

The thing is, SPPU has been having no Dean for its Engineering faculty for about a year or more by now, because the Maharashtra state government hasn’t so far undertaken the procedure to elect (or select) the next Dean.

This recent interview which I mentioned above, was for a Principal’s post, and I was short-listed. As is the common practice here, the short-listed candidates were all invited at the same time, and thus, I had an opportunity to interact with these other, senior-level professors.

These senior professors (some of them already active as Principals at other colleges) told me that it isn’t just SPPU, but all the universities in Maharashtra. They all are currently having only an in-charge or acting Dean for their engineering faculties, because the procedure to appoint the next set of Deans, which was due to occur this month (October) has once again been postponed by yet another year.

Policy decisions such as the Metallurgy and Mechanical equivalence at SPPU have been pending, they told me, because the acting Dean can easily say that he has no powers to do that. Though the other universities are clear that I would qualify, if a genius running an engineering college under SPPU thinks that I don’t, then the matter normally goes to the Dean. If the Dean is not official, if he is only acting, he doesn’t want to take “risk,” so he takes no decision at all. Not just the equivalence issues, there are certain other policy decisions too, which have been pending, they told me. The in-charge Deans have been processing only the routine work, and not taking any policy decisions. The next set of Deans were expected to get appointed by June 2016, and then, after postponement, by October 2016. (“achhchhe din!”)

Now that the appointments have been officially postponed by one whole year (“achhchhe din,” again!), the colleges themselves have begun going to the universities for obtaining the professor’s approvals, arguing that faculty approvals is a routine matter, and that they cannot properly function without having approved faculty.

Thus, the university (SPPU) has begun appointing panels for faculty interviews. There has been a spate of faculty recruitment ads after the current semester got going (“achhchhe din!”).

The particular interview which I attended, these other candidates informed me, was with a University-appointed panel—i.e., of the kind which allows approvals. (Otherwise, the appointments are made by the affiliating colleges on their own, but only on a temporary, ad-hoc basis, and therefore, for a limited time.)

Please note, all the above is what I gathered from their talk. I do not know what the situation is exactly like. (Comments concerning “achhchhe din!,” however, are strictly mine.)

But yes, it did turn out that the interview panel here was from the university. Being a senior post (Principal), the panel included both the immediately past Dean (Prof. G. K. Kharate) and the new, in-charge Dean (Prof. Dr. Nerkar, of PVG College, Pune).

During my interview, if the manner in which Prof. Kharate (the past Dean) now said things is any indication, it means that I should now qualify even in the SPPU. This would be according to the new GR about which I had written a few months ago, here [^]. Essentially, Prof. Kharate wondered aloud as to why there was any more confusion because the government had already clarified the situation with the new rules.

I took that to mean that I qualify.

Of course, these SPPU geniuses are what they are, and therefore, they—these same two SPPU Deans—could very well say, in future, that I don’t qualify. After all, I didn’t ask them the unambiguous question “With my Metallurgy background, do I qualify for a Mechanical Engineering (full) Professor’s job or not? Yes, or no?;”  and they didn’t then answer in yes or no terms.

Of course, right in the middle of an on-going job interview couldn’t possibly have been the best time and place to get them to positively confirm that I do qualify. (Their informal indications, however, were clearly along the lines that I do qualify.)

Now that the Diwali break has arrived, the colleges are closed, and so, I would be able to approach Prof. Dr. Nerkar (the currently acting/in-charge Dean) only after a week or so. I intend to do that and have him pin down the issue in clear-cut terms.

At the conclusion of my interview, I told the interview committee exactly the same thing which I told you at the beginning of this post, viz., that this Diwali means darkness to me.

But yes, we can hope that Prof. Dr. Nerkar would issue the clarification at least after the Diwali. If not, I intend to approach Prof. Dr. Gade, the Vice-Chancellor of SPPU. … I could easily do that. I am very social, that way.

And, the other reason is, at the university next door—the Shivaji University—they did answer my email asking them to clarify these branch-equivalence issues. The SPPU is the worst university among the three in the Western Maharashtra region (the other two being, the University of Mumbai and the Shivaji University Kolhapur). [I want to teach in Pune only because it’s my home-town, and thus convenient to me and my family, not because SPPU’s standards are high.]

Anyway, I now do have something in hand to show Prof. Dr. Gade when I see him—the letter from the Shivaji University staff. … At the Shivaji University, I didn’t have to go and see anyone in person there—not even the administrative staff let alone the acting Dean or the Vice-Chancellor. The matter got clarified just via a routine email. There is a simple lesson that SPPU may learn from the Shivaji and Mumbai universities, and under Prof. Dr. Gade, I hope they do.

… Of course, I do also hope that I don’t have to see Prof. Dr. Gade (the Vice-Chancellor). I do hope that meeting just Prof. Dr. Nerkar (the in-charge Dean) should be sufficient.

If they refuse me an appointment, I will get even more social than my usual self—I will approach certain eminent retired people from Pune such as Dr. Bhatkar (the founder of C-DAC) or Dr. Mashelkar (the former Director General of CSIR, India).

Here is a hoping that I don’t have to turn into a social butterfly, and that soon after Diwali, the matters would get moving smoothly. Let’s hope so.

And with that hope in my heart, let me wish you all a very happy and prosperous Diwali. … As to me, I will try to make as much good of a bad situation that I can.

Still, I don’t find myself to be too enthusiastic. I don’t feel like doing much anything. [In a way, I feel tired.] Therefore, I am going to take a break from blogging.

I have managed to write something more on the concept of space. I found that I should be able to finish this series now. I had begun it in 2013; see here [^].

Concepts like space and time are very deep matters, and I still have to get enough clarity on a few issues, though all such remaining issues are relatively quite minor. I should be able to get through them in almost no time.

From the new material which I have written recently, I guess it would be enough to write just one or two posts, and then the series would get over. What then will remain would be mostly polemics, and that part can be taken on the fly whenever the need to do so arises.

I may also think of giving some indications on the concept of time, but, as I said, I find myself too lacking in enthusiasm these days. Being jobless—despite having the kind of resume I have—does have a way of generating a certain amount of boredom in you, a certain degree of disintegration at least to your energy and enthusiasm, even if not to your soul.

So, let’s see. Let the Diwali vacations get over, and I should come back and resume my blogging, telling you what all transpired in my meeting/interaction with the in-charge Dean, and the related matters.

Since I am not going to be blogging for some time, let me note a couple of notable things.

One, the US Presidential elections. I am not at all interested in that. So let me leave it aside.

Two, the Tata Sons issue. It does interest me a bit, so let me write down a bit on it.

I was not as surprised as some of the newspaper editorials and columns say they were. The days of JRD are long gone. The Tatas already were a changed company when Cyrus Mistry took over from Ratan Tata.

Once I returned from the USA in 2001, despite my resume, I never got a chance with the new Tatas (either at TRDDC or at TCS). Such a thing would have been unthinkable during JRD’s times. … Even keeping it aside, what all I observed about the Tatas over the past 1.5 decades was enough for me not to be at all surprised by something like the current fiasco.

No, Prof. Pratap Bhanu Mehta, reading things from where I sit, the Tata fiasco doesn’t do any significant harm to the social legitimacy of Capitalism in India. People—common people—have long ago observed and concluded what had to be. If what the common people think were to be caricatured, it would look like the position you ascribe to the “cynics”. But no, IMO, this position isn’t cynical. To carry realistic impressions about hallowed icons is not quite the same as being a cynic.

Yes, as Harsh Goenka astutely pointed out in his comment in today’s ToI, Ratan Tata’s tenure coincided with the semi-liberalization era: 1991–2012. Whenever you come to compare Ratan Tata with Cyrus Mistry, you cannot overlook that broad context.

I have always thought that JRD left too big shoes for any one to fill in. But, with due respect to Ratan Tata, I still would have to say that no one could possibly entertain thinking in similar terms, when it comes to Ratan Tata’s retirement.

Looking at the facts and figures reported this week, I don’t think Mistry was doing a lousy job. Reading through his letter, I in fact marvel at how well he understood his job—and for this reason, I speculate that he must have been doing his job pretty well. …

Realize, the letter was written within a day or two after an unceremonious removal from the top post of a 100+ years old Indian icon, a \$100 billion behemoth. Seen against this backdrop, the letter is extraordinarily restrained; it shows an unusual level of maturity. To expect any more “restraint” is to actually confess ignorance of such basic things as human nature and character. (Sadhus, let me remind you, are known to kill each other in their fights at the Kumbh Mela, just for the priority in taking the Shahi Snaan. Keep that in mind the next time you utter something on nobility of character and culture.)

And yes, I also had come to think that the Nano project was doomed—I just didn’t have the sales and profitability figures, which got reported only today. My reasons were simple; they were purely from an ordinary consumer’s point of view. If you are selling the Nano at around Rs. 2.5 lakhs, just think of the alternatives that the consumer has today: you could get a used car in a “good enough” condition, not just Maruti Alto but even a somewhat more used Toyota Innova, at roughly the same price.

Anyway, I don’t understand these corporate matters much, so let me shut up.

But, yes, knowing the house of Tatas and their brand managers, I can predict right away that in the near future, you are going to see the Tatas announce a product like “Tata Quantum Dot,” or “Tata Silicon Dot,” or something like that. … Why do I think so?

I started writing on quantum mechanics, and roughly around the same time, the cable-less Internet, based on the electromagnetic waves (mobile, Wi-Fi) was getting going in India. So, the Tatas came out with the Tata Photon. Yes, “Photon”. The Tata Photon. … It meant nothing more than the usual Internet dongle (2G, and then 3G) that everybody else was already supplying anyway. (And the Tata Photon never worked too well in areas other than in the Mumbai city.)

Then, the USA was abuzz with the catch-words like nano-technology, and the Tata brand managers decided to do something with that name, and thus came the Tata “Nano.” By now, every one knows what it means.

Today, the USA and other countries are abuzz with words like “Quantum Supremacy” and things like that. You can only expect some Tata brand managers to latch on to this buzzword, and launch a product like, say, Tata Quantum Dot or Tata Silicon Dot—or both!

Tata Silicon Dot, I predict, would signal the arrival of the house of Tatas into the business of supplying the sand required for civil engineering construction.

Tata Quantum Dot, on the other hand, would mean that the house of Tatas had taken an entry into the business of plastic dart toys. Or, the business of the “bindi”s that ladies wear. That is what the house of Tatas would mean by the name Tata Quantum Dot.

And here our policy analysts think that something happening to the house of Tatas is going to affect the credibility or social legitimacy of Capitalism itself in India! Oh wow!!

Ummm…. Does any policy research center in India have any data on the proportion of the private business in the overall Indian economy (including both the organized and the unorganized sectors) over the years, say starting from 1930s? Also, the quantum of the government expenditure in the Indian economy, and its proportion in the national GDP over the same period? Would they care to share it, please? Or is it that they don’t have to look at such data for their policy research purposes? … As to me, I have been on the lookout for data like that for quite some time now, but never could see it compiled anywhere. That’s why the request. Please drop me a line if you spot a reliable source.

OK, bye for now.

A Song I Like:

Since I won’t be blogging for a while, let me give away the “other” song right away, I mean the song which had somehow happened to strike me as being similar to the song “too laali hai savere waali”; see the Song I Like section here [^]. This other song is:

(Hindi) “bhigee bhigee raaton mein…”
Music: R. D. Burman
Singers: Kishore Kumar, Lata Mangeshkar
Lyrics: Anand Bakshi

I take the “raaga” of the earlier song (“too laali hai”) as “pahaaDee”—or at least that’s what I got from an Internet search. The “raaga” of the current song (“bhigee…”) isn’t listed at any Web site. Assuming it’s not “pahaaDee” (or a variant on that), the question becomes, why the two songs might have struck at least somewhat similar to me—why, humming one song, I very naturally and casually happened to remember the other song.

It would be interesting to see if Data Science can be used to spot (and quantify) similarities in songs. The traditional music theory puts too much emphasis, IMO, on “raaga” alone. But there can be other bases for similarities, too. The sound patterns of musical pieces, I think, don’t get exhaustively (and at times not even essentially) characterized by the idea of the “raaga” alone. Talking of these two songs in particular, the similarity I caught might have been connected with certain ups and downs in notes with a somehow similarly sounding tempo. The style of the tunes sounds similar. Guess Data Science might be able to shed some light on things like that…. It would be interesting, to look into that, no? That’s what I had thought…

I mean, I had thought. … But then, these days, as I said, I am unable to work on this topic, too…  I just don’t have any enthusiasm left. Honest. I somehow finished this post, only because I won’t be posting for a while…

So, there. Bye for now, take care, and best!

# What are the rules for hiring?

There is a matter of a suspense which should break by the time I come back for my next post. Here is the story. (Narrated, as usual, tortuously and at a length. (Don’t read if such posts turn you off.))

The mechanical engineering professors in the Savitribai Phule University of Pune, as you know, have been pitted against hiring of people with a background like mine: BE and MTech in Metallurgy; PhD in Mechanical. “You must have had at least one of the pre-PhD degrees in mechanical, why didn’t you?” they have been respectively saying and asking (in a probing manner).

Most people occupying the working of the faculty of engineering in this university these days, in fact have come not from the University of Pune (or the University of Poona) itself; they have come from other universities. Typically, they have come from Aurangabad, Amaravati, and Walchand—but not from IITs or IISc or the better ranked universities in the UK/USA.

In my experience (i.e. with the exception of the late Prof. Dr. S. R. Kajale, who did have has UG degree from Amaravati), all of them carry faulty notions about the traditions at this university. In the Pune (or Poona) University, these professors have tried to explain to me, in a tone consisting of a feeling of an utmost certainty as arising from a superior educational experience, the ordinary exasperation arising after not being understood, an abstract projection of an abstract feeling for the acute concerns of the jobless-ness of the person sitting across the table, as well as, all in all, a very definite sense of their own unquestionably high moral and intellectual superiority, that there always has been this policy. [They have never felt it necessary to enjoin in their comment their own experiences or knowledge of their undergraduate universities/colleges. They were in the University of Pune, they knew what they were talking about, the matter ended there, as far they were concerned.]

Wrong. Factually wrong.

The other universities might have historically had this problem, but not the University of Pune (i.e., barring a few well-known personality-related issues concerning the Mechanical and Metallurgy Departments at COEP—the only engineering college this university had, for a long time).

IIT Bombay (with a heavy institutional-cultural influence of the Russians that lasted for too long a time) also have had this problem (concerning branch-“jumping”) but rather in an off and on manner; the University of Mumbai, to my knowledge, never (not at least concerning the specific branches of Metallurgy and Mechanical).

IIT Bombay did have this problem in the mid-1970s; they were against this particular branch jumping (even while promoting their interdisciplinary research centers). Then, during the mid-1980s, they didn’t have this problem. (I could have got an MTech in Mechanical Engineering at IIT Bombay (I had enough of a GATE score to be competitive back then); it’s just that I chose not to pursue anything at this IIT—this IIT was too strong on hype and too low on the academic freedom to the student concerning mixing courses from different departments.) Then, over a period of time, by the time I was applying for PhD admissions during the early naughties, IIT Bombay had once again gone back to having a problem about branch-“jumping”. I don’t know which way blows the wind of their whims, as of today.

So, historically, other universities might have had problems with “branch-jumping,” but not so, for a long time, the University of Poona/Pune. Certainly not before the people from Amaravati, Aurangabad, Shivaji etc. began rushing in to fill the ranks of professorships, in this university. (Surprisingly, the University of Mumbai carried on their more liberal policies concerning the metallurgy and mechanical branches, despite a similar trend of demographics occurring also at its affiliating colleges; I don’t know the reason why. It’s possible that they, too, weren’t being too liberal; it was just that they didn’t have a separate branch of Metallurgy, and so, the issue of the turf-battles and the academic self-inflations of the Mechanical departments, never arose.)

In contrast, COEP and University of Poona actually had no issue admitting BE Metallurgy graduates to the ME Mechanical program—the only requirement was a first class at BE Metallurgy. (And, a higher second, if the BE was in Mechanical itself. Also, vice-versa: For ME in Metallurgy, a first class would be required from the BE Mechanical graduates, and a higher-second from BE Metallurgy graduates.)

Actually, I had forgotten about it—I mean this admission of mine. I was reminded of it when, starting mid-2002, I tried to get admission at COEP, now for a PhD in Mechanical (with a thesis in computational mechanics, on a topic of my choice).

By the time it was April 2003, after having going through 12+ guides (all of who declined to be my official guide), and after having been declined by IIT Bombay (for branch-jumping issue), I finally was accepted by a professor at COEP. And then, the then director of COEP, Ashok Ghatol, kept my application in abeyance for more than six months.

During this time, one day in mid-2003—mid-2004, I received a letter from the COEP library threatening me with a legal action. The letter said that if I didn’t return the books I had borrowed, I would face action by the police. Yes, police, it had explicitly mentioned. The letter was delivered not by ordinary post (the way such letters usually are), and in fact not even by registered post (with the acknowledgment-due slip), but, as far as I remember it, by SpeedPost. Further, it noted that until the matter was legally resolved, I would be barred from many things such as: issuance of any certificate from COEP, applying for a job at COEP, and applying for admission for any further studies at COEP.

I first went through the collection of my books to locate this book, but couldn’t find it. (I in fact didn’t even recognize the book by its title, back then.) Until 1990 (when I went to the USA, and so, some of my habits here broke away), I would keep an excellent record for all the books I had. The book mentioned in the letter was not there in this list. (I would maintain this list in an old 80-page notebook, not in a PC database.) So, I visited the COEP library to figure out the issue. After some four/five visits to the administration building and the library on some six/seven separate days, I finally gathered that the book was supposedly issued to me not when I was a BE student, but when I was an ME student there!

Oh yes! Then the bulb lit up!! I was once a student of ME (Mechanical), at COEP! I had never attended a single class, but I had officially registered for the program, anyway.

Ashok Ghatol, the Director of COEP in 2003–04, it would seem, was being very conscientious. How else could the administration of my alma mater wake up about this library book only now—after a few months after my acceptance by a PhD guide? After all, as far as this library book went, they had never sent a single letter any single time over the earlier 12+ years. But, looking at my PhD application with this guide, they did somehow think of it. Conscientious, nay, very, very conscientious, COEP had turned, in the decade+ time that had elapsed when I was a student here last (in 1989/90).

As would be very easy for anyone to predict, it turned out that the record of the books borrowed by me were, indeed, very meticulously kept also in the COEP library. However, the signature for the last entry on my reader’s card—the entry for the un-returned book—was not mine. It did look somewhat like mine, but it wasn’t actually mine. At least I had a hard time identifying it as my signature. I could convince the library folks about my doubt, but only after not only repeatedly signing in their presence but also bringing and showing my passport to them. Finally, they yielded, and acknowledged the possibility of the existence of a doubt.

But what/who was the source of this extra line? I don’t know. I still don’t. But no, I didn’t even think of accusing the COEP folks with any malpractice. A far more likely possibility here was that some other student (say one of my co-students at ME, or, friends in the Metallurgy department, or a student whose ME project I had informally guided in the late 80s—he had won a University Gold Medal for that project) might have borrowed my library card, and might have used it to borrow a book for their use. (This used to be a common practice at COEP. The number of books to refer could easily exceed the number of books allowed. So, people would freely use each other’s cards, often without knowledge of which book had been checked out on one’s name.) And then, probably, he had forgotten to return the book. Possible. And, of course, there could be other possibilities, too; I don’t know. (The book was not on a topic of one of my own interests back then—viz. computational mechanics.)

Anyway, even as I became very well aware of Ghatol’s utmost conscientiousness by this time, I also, by this time, was a sufficiently grown up educated Indian to be well aware of the way that Indian governments work. I would be asked to pay a fine, I was sure. And the fine, I was sure, would be within a few hundred rupees. It would have to be only a fine, not a book-replacement. Two reasons: (i) There would no possibility of book-replacement for the COEP library. The missing book, I think, was an old one, and so the possibility of finding a replacement was remote. Further, this being a government college, a policy of book-replacement would, in principle, go against the policy of procurement of any of the library holdings only in the bulk and only by the college itself, not by a student, and only from one of the approved list of book vendors. (ii) The rules for the fine would refer only to the original cost, not to the current market price, or the price arrived at after accounting for inflation. The settlement of issues via the latter route would not only violate the principle behind the procurement policy, but it would also require making a reference to the State Accounting and Finance Department in Mumbai, and there in fact would be no precedent or a policy on how to make this reference—none would even know what category the outward register’s entry should note.

I didn’t divulge the above two reasons to the COEP staff; I merely let them decide. Of course, it took a few visits to the COEP library and the main administration block, before the whole issue could be settled. The end result was, I ended up paying a fine, I think an amount less than Rs. 500. (Yes, I had to write an application, get it endorsed from two different people each in the administration block and the library, fill four copies of the challan, get them endorsed, and then go to that World Famous branch of the SBI on the COEP campus, to make the payment of this fine.) But yes, this part of the institutional objection against my PhD admission was, thereby, cleared.

But of course, obtaining the library clearance took sufficiently long time that, COEP, under Ashok Ghatol, had in the meanwhile revised the list of Emeritus Professors in the Mechanical Engineering Department, and thusly, the only guide who had accepted me as a PhD student (after a search for a guide lasting for one year and going over 12+ guides), was now denied a continuation of his Emeritus Professorship. He was declined an extension at COEP despite his having retired from COEP as a HoD, despite his being active in the field of education—including being on the board of an NIT, and despite the national level Fellowship which he had at the same time been granted by the UGC/AICTE at New Delhi. He still was declined an Emeritus Professorship. With no active professor at COEP available for guidance (it would be some months before I would approach Prof. Kajale), the matter had come back to square one at COEP.

BTW, in case you don’t know, the current dean of the Savitribai Phule University of Pune, Gajanan Kharate, has done his PhD under the guidance of Ashok Ghatol.

But of course it would be too much to expect that Gajanan Kharate could possibly be aware of the kind of institutional memory that the institutions under the University of Pune are capable of keeping: being aware of such possibilities requires a finer and longer experience with institutions in general.

Therefore, it would be too much to expect of him that the same University where he currently is the Dean, would, as recently as in 1990, in fact allow the mixing of the metallurgy and mechanical branches—even at the ME level, not just the PhD level (where the rules are anyway more relaxed).

This better practice was stopped only some time later, roughly around the same time that the IIT Bombay changed its whims in their regularly irregular course. It was the same time during which the hoards of the even more enlightened souls from the Amaravati, Aurangabad, and Walchand/Shivaji universities (but not those from IISc or IITs or foreign universities) had joined the ranks of the Approved Professors at the University of Pune. It was also the same time during which COEP’s name was slapped with the “Government” prefix, to make it fall in line with the similar Government-run colleges elsewhere in the state. If COEP had later dared to drop this part of its moniker (which, too, happened during this same period), then its alumni couldn’t possibly be relied upon to know about the better practices concerning engineering education elsewhere. Conscientiousness would be a key value to keep, especially during those troubled post-liberalization times, and especially in respect of the more exceptional ones among the COEP alumni—at least those who thought of themselves as being exceptional, anyway.

Now, cutting to the present, as far as this branch-“jumping” issue goes, there were many people wanting to go back to the (somewhat) better times, of course. (I know of at least one past Dean of Engineering of the University of Pune who did. In fact, two.)

Some other people were really not aware of the better times, but they simply faced the practical inconvenience of not getting a Government Job, and so were trying very hard to persuade both the university as well as the state government. The Maharashtra state government could only be sensitive to the representations if these were made in a democratic manner, and it would only be willing to review the mere technicalities involved, but of course, according to its own time-table—as a part of its ongoing Plans for a further expansion of the state expenditure.

Thus, while the efforts of these other people at the Savitribai Phule University of Pune didn’t at all bear fruit—I suspect that something other than conscientiousness might have come in their way—their tenacious representations to the state government certainly did. Over a period of some three years (give or take a few), the Mantraalaya finally did come to the point of concluding its ongoing reviews, and thus come to the point of issuing a GR.

It was thus that, in mid-2014, the Maharashtra State government came out with a GR affirming certain new eligibility criteria for the hiring of professors in the Government-run colleges in the state, as well as for the non-aided colleges in the state. These new criteria included allowing the graduates of the production, metallurgy and materials science branches (as also certain other new branches such as CAD/CAM, CFD, etc.) to become (full) Professors of Mechanical Engineering, if the candidate also had his PhD in Mechanical. (If he has a PhD, but if his PhD is not in Mechanical, the candidate now can still be hired, but he can now become only an Associate Professor, not a Full Professor. But at least, he can now get a job in any university falling under the jurisdiction of the Maharashtra State, now. More importantly, he can get a Government Job.) Including at the very highly conscientious university that is the Savitribai Phule University of Pune, Pune.

The GR had come out in the mid-2014. However, I didn’t know about this development. In the University of Mumbai, none was aware. None of my numerous friends (more than 10) working as Professors, HoDs, and Principals, in the private engineering colleges in the Savitribai Phule University of Pune, knew about it. Not a single one of them. And, Gajanan Kharate, even if he sure would be aware of the development, did not clarify the matter in response to the emails I sent (keeping him on the cc field for my application for a Principal’s position). In fact, he sent no replies at all—not even to the other email I wrote; this email was addressed to my friend’s friend (and a COEP alumnus), one who is a Principal at one of the (better) engineering colleges in Pune, and whose ad I was responding to. The Dean didn’t deem it fit to clarify the matter to a Principal of a leading engineering institute in Pune.

So, how did I come to know about the GR?

Only by accident, and only around mid-June 2015, i.e. one full year after it had originally been issued, while idling browsing the Web site of COEP. … You see, I have been looking for an opportune time to show them—the current COEP professors—down, and so, I sometimes do check out their Web site, esp. their recruitment section. For their latest recruitment advertisement, COEP had now put up this GR on their Web site. That’s how I came to know of it.

But, by this time—mid-June 2015—professors’ posts at the leading colleges in Pune had already been filled. (I saw all their advertisements in the Pune papers during April and May, but ignored all of these, concentrating my efforts instead only on the colleges in the better run University of Mumbai, because Mumbai had no issue concerning the metallurgy-to-mechanical branch-“jumping.”)

Anyway, the point is that after mid-June, I began applying to (and indeed also sporadically interviewing at) the private engineering colleges affiliated to the Savitribai Phule University of Pune.

The current status is that chances are high that I would get a job offer at at least one engineering college in Pune. I have been offered a position by phone and I have confirmed my acceptance by phone, but I have not received the offer by email. Once the latter happens, I will update this post when that happens.

I also want to see if this blog post goes against my getting that job offer (or any other job offer). No, not exactly for fun, but I do want to do that. … It’s just me, you know… I am just so talkative. And, readative. And, also, writative. Blogative, in fact. … I just can’t help blogging…. And so, it’s quite natural to want to see if (my) blogging habits come in the way of (my) getting job offer(s). Check back for any updates concerning this aspect.

Update on the same day (2015.08.11, 5:30 PM): Yes, I have received the job offer by email. I should be joining the college right this week. More, later. [The section on a song I like has returned immediately, however; check out below.]

[Some editing, as usual, is due, and I may effect it, but I am not in a hurry. Done. I may go out of town for something other than the job-related matters, too, in the meanwhile…. Either visit a friend, or go on a short trip driving in the mountains, or something like that… Check back after a couple of days…]

I won’t take chances. This was a comment I just made this morning at Prof. Dheeraj Sanghi’s blog, here [^]. Comments at his blog are moderated. And, I don’t know if he will allow it in. (There could perhaps even be some valid reasons for this comment not to be run there.) So, I have decided to go right ahead and note my comment here, too. (On second thoughts, as I have often said earlier on this blog, I anyway think that I should be bringing here many other comments I have made over a period of time at many other blogs, too.)

Here is the comment I have just made at Sanghi’s blog:

* * * * *   * * * * *  * * * * *

Quote:

Dear Dheeraj,

You write interestingly, even engagingly. Well, at least, you write—as in contrast to mostly just excerpting from Internet links!

I don’t mean to fully defend the practice that has been adopted. I just wish to note down out a few points that seem to be contrary to the flow of your argument, a few points that passed through my mind.

When you recruit a lower-level employee, a PhD student, or a professor, you do follow the meticulous process you mentioned; it involves lengthy interviews, too. Why might someone not follow a similarly long interview while recruiting IIT directors?

I think that some at least plausible answer may be hidden right in that question.

For the starters, when it comes to the candidates for the director’s post, as against the other posts you mentioned, simply because all the candidates have already been subjected to a meticulous process, throughout their prior career, typically spanning over decades.

They have been observed and evaluated at the senior and responsible positions for at least a decade or more by multiple, disparate, parties. … Any comments they make at professional conferences, any viewpoints they offer at the industry-institute interactions, the quality of the documents they write for obtaining funding, etc. Also, the blogs they write [ 😉 ]. And, they have been continuously evaluated by various parties: h-Index (certainly), student evaluations (if these are taken seriously at IITs)—and, certainly, via the annual reviews from their seniors, which includes mandatory remarks from the viewpoint of their potential as leaders. The CRs (annual confidential reports), made over a decade+ times (through various political dispensations, under many different HoDs and Deans and Directors) do have some purpose, you know—i.e., if these are taken seriously at IITs!

They also have been short-listed by the formal selection committees. Presumably, the committee’s role does not end only with providing an unordered list of names. Presumably, the short-listing committee takes its job seriously.

IITs are not private institutes. The top decision makers here, by explicit organization structure, are the concerned ministry/ministries. Whether you like it or not, they do have their regular input channels, too—channels other than the selection committees. In India, in case you have happened to overlook it, we have more than 10 central agencies for internal intelligence gathering. When the body called the Planning Commission got dismantled, another one stepped in to fill the vacuum.

Another point: At the director’s level, IITs also typically do not go for rank outsiders. Most, if not all, of what I say would remain valid even if the candidate is an outsider.

The cumulative input from multiple sources thus is already there. It is distilled, and available, just in case not already factored in, by the time the short-list is made. And, then, there are internal reviews.

The final interview, thus, is more or less just a formality. Shocking? Why should it be, to you?

And, doesn’t this happen in the USA anyway—and I mention this point, because I know that at IITs, esp. at IITK, a top-10 US PhD is routinely valued better than a PhD that COEP graduated after a failure at a PhD program in a 50+ USA school. Thus, mentioning the US practice should be perfectly acceptable.

Would a colleague of yours in the USA—one who values your word—even bother to talk with someone you strongly recommend, i.e., with a personal touch of yours? Do they? actually? even for just five minutes? Especially if they themselves know someone trustworthy other than you, who personally knows the post-doc applicant? Do you find their practice offensive? Did you find it offensive when Manindra Agarwal’s students received offers for post-docs etc., even before submitting their PhD theses at IITK? Did you begin blogging something about the fact that there was no 30 minute interview, not even 5 minute interview for them? Do you hasten to wear your skeptical glasses if an IUCAA PhD student gets a post-doc offer at Princeton or CalTech even before submitting his thesis?

At this point, you should be a bit bemused, perhaps even a bit agitated, but you would still not be convinced. There is a bit of valid reason for it, too. I can understand and sympathize with your viewpoint.

You see, I myself have undergone a similar kind of a process—the kind that you criticize. When I applied for a professor’s position at COEP, what actually happened was that, apart from submitting my application (manually making sure that it was duly entered into the inwards register), I then dropped by a few professor’s cabins in the department, and then, also the Director’s cabin. I broached the metallurgy-to-mechanical branch-jumping issue with him, and sought his opinion about it. To cut a long story short, he bluntly told me that he has had no objection on that count (it was he who had given me an opportunity to teach an FEM course before my PhD thesis was defended), but that, as a director, what the department thinks, he said, was more important to him. And, while the department had thought differently earlier, when my PhD guide was still in it (or had just left it), now the department had begun “thinking” some “different” way.

I was duly short-listed, called for the interview, and it became evident to me within the first 1–2 minutes the nature of what to expect. (Doesn’t it, if you are past your 40?… In my case, I could tell right when I was in my 20s.) The interview did last for about 30 minutes—I stretched it, because I wanted to tell them in sufficient detail—while all along, they were just wanting to hurry it up and wrap up it all. … To cut a long story short, in the end, they selected someone whose thesis had been examined by a low-ranked NIT’s low-ranked professor, whereas every one in COEP knew that my guide had, on my informal remarks, dared contacting people from top 5 univs in the USA for examination of my thesis (including Frank Wilczek). That none of them bothered to examine it is a different story. The end result was that after almost 1.5 years, my thesis was finally picked up for examination by two senior professors from one of the five old IITs—both of whom had been HoDs and Deans, and one later on was a Director of a central lab. Now regardless of this difference, COEP showed me the door. As expected and made clear right during the interview process. (“Are you now casting aspersions that we don’t know what is good for this institute?” etc. When I say I had stretched them to 30 minutes, I mean it. After taking the decision, they did not take care to inform me of the outcome. I saw the director. He managed to sympathize with me. Though he didn’t say a thing, I knew that he knew that I knew that I should have known that I would not get selected.

Just a COEP professor’s post and an IIT director’s post, there is a difference, you say?

Well, Dheeraj, you then speak more like a typical IAS officer or a second-rate corporate MBA, than like a professor. If a director directly impacts some 500 faculty members over his entire term(s), a professor impacts some 500 students every year. And the impactees in the second case are both far more sensitive and powerless. And, with far longer period of their future at the stake.

If there were to be betting rackets for IIT Directors’ positions, the going rates would almost consistently get the selections right, regardless of change of political dispensations, and without the benefit of even a one minute interview. Why is a five minute interview so difficult to get by top ranked IIT professors, cognitively speaking.

And if you still say that the five minutes interviews still are not acceptable because the process can result in wrong/bad selections, well, you only join me, my argument—you cast doubts on the short-listing and the real reviewing processes, on the grounds that some people who could easily become second-rate directors, too, had got short-listed by the selection committee. Exactly similar to what happened to many other candidates in the COEP process. Not just short-listing, but the internal reviews before the interviews even began.

But then, who blogs about a non-JPBTI anyway—let alone for him? Who defends him? Answer: None—if his PhD guide is dead.

These are some of the things that passed by my mind, while thinking about this directors’ selection issue. I don’t pretend to know or understand the full situation. But I do know that what I said is, in many important ways, relevant.

Best,

–Ajit

I had made one comment in response to a post and a couple of replies, at the nanopolitan blog, here [^]. Since the comment was long, I had saved it. To my surprise, for some reasons not known to me, it was gone the next day.

If they were to run my comment, it would have appeared immediately after the comment by one “Sushant Rai” (on 4:36 PM, March 23, 2015).

In the next section I copy-paste my comment (which, as I said, assumes the context of the previous discussion) exactly as it originally appeared (including mistakes/typos, and the emphases in italics or bold):

* * * * *   * * * * *   * * * * *

Quote:

No, Ankur, there is a basic difference between an academic institution and a corporate house. … You would know about it, but just in case you don’t, check out Dijkstra’s article on academia, here: http://www.cs.utexas.edu/users/EWD/transcriptions/EWD11xx/EWD1175.html

Now, a bit about the similarity. Mistry is the first non-Tata to head the house of Tatas. The party to hold the purse-strings does make the key difference. Whether it’s the majority or the critical shareholders, or, the controlling politicians and/or bureaucrats.

If TIFR were to be a private company (e.g. a coaching classes company), then what you say would have been applicable. It emphatically is not.

Government interference in economy is always bad; the public sector science and academia is no exception. The academia would survive (cf Dijkstra) even on public money, but don’t count on keeping quality. The broader context itself is wrong.

If you ask me: If anything, be thankful to your luck/stars/etc. that you all at IIXs etc. still get to exercise at least as much freedom as you do. The broad systemic nature doesn’t actually allow it. … Some memories of some decent traditions of the yesteryears’ private universities abroad, and some memories of some decent simulation thereof here, is the reason why you still get as much decent a treatment as you do. Visit a “private” engineering college and ask around.

As to a director’s post, I do think that these, too, should be publicly advertised. And, the names of all the people involved in the decision-making process should also be publicly declared as well. One shouldn’t have to file an RTI application for that.

After all, the government/public sector also is far more easily susceptible to the old boys network sort of a thing, as compared to the corporate sector. (There already have been articles in the media about how even some retired judges have landed plush jobs immediately after their retirement, and how courting for favours (!) might have gone before their retirement from career 1.0.)

As a long-time sufferer at the hands of those who have peopled the premier institutes in the Indian education system (“What? Metallurgy? Why did you come here? Don’t you know this is the Mechanical department?” and “What, only GATE? No JEE? You are worse than a dog then!” (Ok, this second bit is a bit of an exaggeration)), I do like it when it does receive a dose of its own medicine once in a while.

And I am sure, Sandip (Trivedi) won’t go jobless in the meanwhile—he cleared the JEE, did PhD under Preskill, and co-authored with Frank Wilzcek. He will get to continue at the scenic Colaba campus in the meanwhile, too. That’s the bottom-line. (Or at least the one I draw.)

Best,

–Ajit

# My comments at other blogs—part 1

Introductory:

I sometimes post comments at other people’s blogs. Since a thread at these other blogs often is only partially related to the points I am interested in or am making, I don’t always have enough space to explain my points at that blog. Yet, simply in order to note something, I do infrequently post a few comments, thinking that I will return here (at this blog) and expand on those points later on. Yet, most often, what happens is that I simply forget the points once they are thus jotted down elsewhere. All in all, I have been wanting to improve on my “notes-keeping” techniques—it’s been getting messier and still messier!

While it would be ideal to provide some further explanation on the comments I thus make elsewhere, doing so would usually take enough extra effort that whenever I think of doing so, I immediately slip into that nice and comfortable and very cozy zone of… what else? procrastination.

I have, therefore, thought of a compromise solution: To provide (at least just) the links to the comments I have written elsewhere. This way, I will at least not forget the points which I need to expand on, later on. After all, this is my blog; I do take its back-up; and so, anything that I note here will stay somewhere at least in the backups (if not also in the mind); it won’t go permanently out of my mind, and therefore all lost to me.

Thus, from this post onwards, I will occasionally be lumping together a few links to my own comments elsewhere, via a post specially dedicated to such links, here.

Further, I have also decided to highlight some other interesting blogs or posts from time to time. Thus, though this blog was heavy on my own writings thus far, in future, it would also have a bit of a mix of other people’s blogs.

* * *

Recently, I have made a few comments at a CalTech+PhDComics blog post on animation of quantum matter. The post in question is here: [^].

Among the many comments I made there, I think my more notable comments are: this [^], this [^] and this [^]. Let me tell you why I think so.

But before that, the right time to visit that blog-post and to go through all comments—mine as well as others’—is: right now.

From this point onwards, I assume that you are familiar with both the post and all the comments it received.

OK.

The first of my comments [^], though deliberately long, basically tries to take away that “quantum” kind of an aura which invariably engulfs any mainstream QM-based explanation of any QM phenomenon. Here, Prof. John Preskill and Dr. Painter had (probably though not at all very deliberately) introduced precisely this element of a mystery, by highlighting the asymmetry part of it, without providing any clue as to why the asymmetry might be arising. As soon as I saw the video and read their answers, I thought they were going overboard in emphasizing that asymmetry part.

In laying emphasis on the fact that this was not a simple, passive mechanical oscillator but one that was being actively (nay, aggressively) being kept cooled down to the near-absolute zero temperatures, I tried to remove that usual “quantum” sort of a fog surrounding the issue.

BTW, though it’s a minor point, in my comments, I also tried to indirectly emphasize the fact that starting from a non-absolute zero K temperature, you cannot ever hope to reach 0 K. This is not an issue pertaining to an ignorable kind of a small number; it’s not a matter of a relatively insignificant experimental error; it’s a matter of an important principle—of a law of thermodynamics. You don’t begin to violate laws of thermodynamics in your presentation just in order to make the matter look sexy to some clueless American high-school students or their equivalents there or elsewhere (regardless of their age, education,  alma mater, the obtainment of a tenure or a VC funding, fellowships obtained from professional societies, instances of their otherwise competent PhD students being unethically flunked during qualifiers, etc.). You don’t do that. You don’t have to, in order to either highlight the achievements of science or even to make it attractive.

The second and third of my above-mentioned comments (i.e. this [^]  and this [^]) introduce what in that context perhaps is a novel idea. Apparently, people haven’t pursued the single-quantum versions of the experiments which study the transfer of a quantum state from light to a mechanical oscillator (or vice-versa). Perhaps, before I introduced the idea, they hadn’t even thought of doing so—not in this context. (Such things are easily possible.) In any case, they should pursue such experiments. Why?

The reason is twofold.

Firstly, these days, there seems to be a new and special streak of QM skepticism gaining some traction, esp. in the American science circles.

For instance, no sooner does a private sector Canadian company D-Wave introduce some new version of their hardware than a small army of the NSF/American public R&D-funded skeptics launch scathing attacks on all its claims. For instance, see the nature of the comments at Prof. Scott Aaronson’s blog [^]. Being extra critical of extraordinary claims is perfectly OK, nay, it is even demanded by the rigours of science. But being skeptical never is: skepticism, even an informed skepticism, is not a route to knowledge. Skepticism only destroys knowledge.

Now, coming to Prof. Aaronson, inasmuch as he does maintain that extra rigour of criticism, he is to be encouraged and applauded. In fact, when he apparently isn’t too busy (or too passionately in the thick of the thrust and parry, i.e. “debate”), Prof. Aaronson himself seems to be pretty well-balanced about the issue. (He obviously has a tilt against D-Wave, but he also, equally obviously, has absolutely no axe to grind here—that much is clear. And, when it comes to summarizing, it’s good that he forgets the more shallow among many of all those con points (sometimes his own, too!), and thereby ends up presenting a pretty well-balanced viewpoint. Not necessarily the most comprehensive picture, but still, a pretty balanced one in terms of what all it does consider, anyway (and he does cover an impressive lot of the territory.))

Yet, if you go through all of those hundreds of comments (sometimes even 600+ comments) that each of Aaronson’s posts generates, you would certainly come out getting a definite feeling that something deeper is at work here than what meets the eye at the surface. Not just a feeling, not even just an evidence of sociology, but more: you will come out also with a lot of links pointing towards hard evidence too.

It’s almost as if someone or some influential group in that giant, American government-sponsored, R&D machine has decided to throw the monkey wrench into any QC works, esp. that elsewhere, by “showing,” sometimes even via dishonestly thin argumentation, that any new results favoring scalable QC is either unbelievably unreliable or that there is nothing QM-ness about it, that the result is what should be expected on the basis of classical mechanics alone. (BTW, “government-sponsored,” or, better still, “government-controlled” is what the phrase “public science” actually translates into.)

Of course, the “public science” in America is not the only party against any of these scalable QM kind of claims (or even experiments). Dr. Roger Schlafly [^], a more or less completely independent researcher, too, has flatly denied any possibility of ever building a scalable QC. He doesn’t have any specific evidence or a principle to cite in defence of his position. Apparently, he just feels that way. Oh, BTW, Prof. Scott Aaronson (himself) has (justifiably) criticised Schlafly.

(BTW, I otherwise have a significantly good opinion of also of Schlafly’s judgment, much of it formed in reference to his book on Einstein. I haven’t read this book completely, but from whatever portion of it that I read, it seems to be a very well written, and an even better researched a book. (BTBTW, the Google Books Preview (still) allows you to read this book in its entirety. It’s just that I haven’t found the time to complete my reading. (TBD!)))

Anyway, coming back to the issue at hand: With this background, I thought that Dr. Mankei’s comments at the above-mentioned (CalTech+PhDComics) blog post came perhaps a bit too early, and perhaps they were not sufficiently thought through. (He also immediately posted an independent paper to arXiv, for this purpose!)

Secondly, in any case, what I wanted to point out and emphasize was the possibility of a way that should convincingly show the quantum nature of the mechanical oscillator in this kind of an experimental arrangement. Overall, I am happy about suggesting the single-photon version of this QM experiment.

I sincerely believe that not only is the single-photon regime interesting in its own right but that in systematically reducing the flux by some 15 orders of magnitude, we could perhaps also be covering some interesting intermediate regimes as well.

Of course, the main point still concerns the single-photons regime. If you see the red-shift even in the single-photon regime, but no blue-shift, I believe that no one will be able to come up with a very rational argument interpreting such a result in a classical mechanics framework. And, a systematic reduction of light flux should provide additional clues to the way that the quantum nature of matter emerges gradually.

It’s true that our intuitions can so easily go wrong once in the quantum realm. Yet, my own intuition is that even if not in this particular experimental set-up (i.e. with this big a beam for the mechanical oscillator) then at least in a different but similar experimental set-up, the quantum blue-red asymmetry would continue to show up even in the single-photon regime. (TBD: write a post to indicate the reason behind keeping this intuition.) It should make the critics skeptics fall silent (for a while!!).

One final note. If you wish to see more comments on this matter, see Sean Carroll’s coverage of the same experimental development (and the same PhDComics-produced video) at his blog, here: [^].

* * *

I have quite a queue of (even very recent) comments I made elsewhere. I should be back with a couple of them pretty soon. Also, a few interesting links.

One more series! … What happened to the earlier series on tensors?:

I will resume my series on tensors once I get settled in Karjat. As of today, I am too busy organizing my stuff for the relocation to Karjat. And, I anyway don’t have a scanner at home. (Have been jobless, remember?). Friends whose scanner I could have used also all seemed to be too busy these days. So, I have decided to postpone the tensor-related series for a month or so. I will do the experiment myself and resume the tensors-related series in or after mid-July.

# Trivia Like the M. F. Hussain Controversy and the Women’s Reservation Bill

0. With this post, I once again resume blogging…

First, I need to quickly get a few things out of my system before I am ready to write on some of the things I have wanted to write about. … So, here we go with the more trivial (but far more discussed) matters first…

(1.) About the M. F. Hussain Controversy…

There was a spike of discussions concerning this particular controversy about one/two weeks ago. So many interesting angles got thrown up that it would be impossible to even summarize them. I felt like jumping in, but instead, just kept on reading on the ‘net and otherwise, to get the “lay of the land” before I wrote. In a way, this turned out to be a good decision.

After all, I did find a very highly quotable position post which explains most of what I had wanted to say anyway. By that, I mean the post on the topic by Dr. Atanu Dey, here [^]. Please do read it. Highly recommended.

Not that I agree with every nuance of every point he states. Speaking in overall terms about his blogging about other matters too, I suspect that there might be a difference among us in that I might look at something from a moral/judgmental viewpoint whereas he wouldn’t, necessarily. That hardly matters here, though…

Here, I find his ability to think in principles, and the straightforward way in which he puts his thoughts, marvelous! And I completely agree with all the essential points of this post of his.

Just a couple of points I shall add to what Dey has already said.

(1.a) Dey says that “[he is] not much of a paintings person, anyway.” But I am, to a certain extent. And used to be one to a major extent about two-three decades ago. So, I can add a bit about this matter.

The question I very briefly address here is: how great is Hussain, as a painter (i.e. artist)?

Even a casual glance at his paintings would tell you that he has an extraordinary mastery over the line. He is an abstract painter—which, to my mind, generally speaking, doesn’t qualify as art to begin with. This applies as much to Hussain as also to Souza, or Gaitonde, or Anjali Menon, or even Sujata Bajaj, or anyone else of their kind—which means, about 99% of today’s painters: they, too, are not artists.

But keeping this aside for a moment, the next question is: Doesn’t he show at least some elements of great art in his work?

Here, I think, as a craftsman, his defining skill is not at all light and perspective, certainly not color, nor even subject, but it’s: his line. His painting unmistakably show that had he chosen higher goals, he would have made for a recognizably great artist—and, despite spending 95 years of his life, he still has not managed to even become an artist let alone a great one.

But why do I say it’s the line which really defines his craftsmanship? Just look at the lines that define the contours of his horses, and the women he paints. His line is capable of bringing to life the sheer life power, the very unruly dynamic, of a horse. Just one apparently careless stroke of a brush in the right place while drawing the eye of a horse, and that raw, unruly energy of the horse begins to jump at you. Similarly, consider the fact that despite carrying the crudeness of the abstract technique, his straight lines still perfectly capture the contours of the feminine form, whenever he manages to slip-in to the remnants of the better elements of the technique he must have been taught at the JJ School of Arts.

So, here is a very curious phenomenon. You have a gifted craftsman—at the level of the line. But this same guy, then, refuses to use that gift to paint a picture—i.e. to create a work of art. Instead, he uses his more abstract powers to mangle the elements like the objects making up those lines, the color and the perspective etc, deliberately disorients them all, throws them together to deliberately create incoherence or even un-intelligibility in his work of “art.”

Consider its counterpart in other forms of art, for example, literature, for example, poetry. What Hussain’s approach would yield is not a poem but something like a poem. Of course it would be called a “free verse.” But the matter doesn’t end there—it gets worse. What Hussain would give you would be a collection of in-principle disconnected bunch of lines, some phrases of which being extraordinarily brilliant on counts such as drama, innovation of expression, metaphor, imagination, etc. Mind you, the brilliance would be restricted only to phrases, not even to lines—the mangling would begin right at that level. And, the lines, taken as sequence, would all be disjointed, hinting at something which, in principle, cannot at all be known, not in toto. The hints themselves could at times be grotesque, at other times sly, at other times profane (and this term is to be taken in its objective sense, not necessarily in connection with this religion or that)… You could, if you try, easily locate Hussain’s parallels in modern “poetry” too. The point isn’t that. The point is to convey what Hussain really is like, when taken as a painter. Namely, that he isn’t one.

(It would be an error to compare Hussain’s paintings with the strokes produced by a student studying at a school for the mentally retarded—the first has the ability to do better, the second doesn’t, and the deliberateness of the rebellion against integration is the crucial difference.)

(1.b) Another point that many people seem to have missed is this. I ran across a court judgment that did agree with the opponents of Hussain in all other points. However, it refused to try Hussain on a point of legal technicality. And, that brilliant piece of the legal technicality was supplied by the current Central Government of India minister Kapil Sibal. … The less I say, the better it will be to my health and life…

(1.c) Nevertheless, we must stop and ask ourselves one question. If merely brilliance in respect of an element like the line-work can be enough to qualify a guy to be counted as an artist, even when ample evidence from his art-work as well as his interviews exists that he has deliberately followed a policy of working against proper integration as required by a proper piece of art, then, following the same standards, why not also consider those millions of anonymous Indians whose “work” adorns the walls of all our public urinals to be artists in their own right, too? [And, I deliberately use the word “urinal” rather than “toilet” or “rest room,” because only the former can adequately convey the strength of the stink in question.] Why not decorate also them with those Padma awards?

(2) About the Women’s Reservation Bill

First of all I want you to note that here I am going against many politicians I otherwise respect, first and foremost, Sharad Pawar. Also, many other politicians I fear. … The reader must excuse me here; there would be too many to name them to list them individually. …

The best commentary—and the only reasonable one—that I saw in print or on monitor, came from one Mr. Parsa Venkateshwar Rao, Jr., in a column he wrote for DNA, here [^]. The only other media/blog to highlight it (in my limited browsing) was “Churumuri,” here [^].

… As usual, at least one qualification. What Rao calls “politics of identity,” I would call such things as “politics of narrowness/of insularity/of divisiveness.”

And, here’s the extraordinarily brilliant part of Rao’s comment, expressed so tersely but so well:

…Women’s reservation bill too is supposed to promote gender equality but what it really does is create yet another special interest. And society is turned into a bureau of cubbyholes. And the power of the State is increased yet again. …

Thank you for saying it, Mr. Rao!

To Swamy of Times of India, regarding his today’s column. Nope, Swamy, you don’t get it right. Hmm…

Back to basics. There are three pillars of a nation state: (i) legislative (L for short), (ii) judicial (J for short), (iii) executive (E for short). In India, the mangling of the E branch began right with the original version of the Constitution (C for short)—it’s just for five years, no principled, i.e. unreserved respect/acknowledgment of the individual rights, etc. As such, the J, if pushed to the wall, would have been helpless, in principle. For the aforementioned reason (viz. the absence of an explicit ack. of the Individual Rights), the Constitution always had been sufficiently vague—i.e. weak–that if L grew, it could not only overpower the E but also effectively restrict the J in various indirect ways. Enter the mixed ideals of Nehruvian socialism. L had become powerful. In Indira’s semi-dictatorship, it changed C and systematically weakened L and then also J. With the fall of the Berlin wall and the collapse of USSR, there seemed to be a reversal of sorts, but it was necessarily doomed because C was weak to begin with anyway so there was poor theory, and, in fact, Indira’s years had weakened the level of the public discourse to such low levels. So much so that on this issue of reservation, all major parties—Congress, BJP, and the communists—they all agree. (Also all the rest of them: they simply fight for greater reservation—not less). Ok.

Against this background what would this Bill do? There are certain implicit grounds for negotiating any kind of agreement in any free society. Due to a better past—and interactions with better countries like the USA and UK—despite the systematic abuse of the above sort and all the weaknesses of the Constitution and legal codes, the common implicit grounds in India actually tend to be better. This is the reason why gays (as much the “chhakke”s as the more hype urban ones) could at all live without having cases slapped against them. This is the reason why in Maharashtra, the ANS-sponsored Bill gets halted. (The reason I oppose it: What standards would permit an ordinary police officer to distinguish between proper private practice of religion and blind faith as prescribed by ANS?) This is the reason why business can at all in fact function even if enough legal codes exist that in theory it would be impossible to run a business without breaking some or the other legal code. That implicit ground is important.

In a country with as huge illiterate, semi-literate, and literate-but-uneducated population as India, a country where to run the elections you have to use symbols—not candidate’s names—it does matter a lot what kind of signals we project to all those people.

When reservations in jobs came into force, it actually did not matter to large parts of population: most of the labor is in agriculture or unorganized sector, and even in organized sector, job reservations applied only to government jobs, not private. It was bad, but it was limited in terms of impact. When the Constitution got mangled almost with each successive amendment (some of which being more deeply mangling than the others), it rather affected the upper echelons of the society—their effects on that implicit negotiating grounds that I alluded to above was at least initially minimal; in any case, their effects would have to slowly trickle and diffuse.

But when you introduce a Reservation Bill of this sort—whether on the caste basis, gender, or any other, it matters not in principle—what you do is that you not only mangle the L branch of the government out of its shape, but, since the common illiterate man, right since the Freedom Movement, has always been an active part of the political process, you also affirm to him that divisive agendas like that are alright so long as ratified by an overwhelming majority, as led by the likes of Sonia Gandhi and Sharad Pawar and Advani and others.

In other words, you affect that implicit understanding of what kind of state one lives in, for that common illiterate man. In essence, you tell him: It’s perfectly “sarkari” to be prejudiced against any innocent man. It is perfectly OK to be prejudiced. It is perfectly OK to be so even at the level of elections for law-makers. It is perfectly OK to follow the blind politics of special interest groups.

The first implications of this kind of a message has already emerged, in the form of the opponents to the Bill. … And, Sharad Pawar, and Sonia Gandhi, and Nitin Gadkari, and Brinda Karat and their lesser colleagues all find a cause to celebrate for. What a tragedy!!

. . . . .

[BTW, if someone from NCP or Indira Congress comes and asks me (which is very unlikely), rather than give them a lecture on principles and all, I am just going to be a bit smart and raise a few points in turn: (i) Why did “Sakal” stop carrying the news of new PhD awards precisely around the time I was awarded one—and why does, through other columns, it does sometimes (even if rarely) does cover the news of other PhDs… Is “Sakal” ashamed of the kind of work I had submitted for my PhD? (ii) Why did I not get that job in COEP—even after my PhD defence? [^]  (iii) Why did the IIT Bombay Conference ICCMS09 reject my paper (citing such flimsy grounds that I had used the grammatical first person while writing the abstract)? Who gave them the encouragement to behave thus anti-intellectually? (iv) Why did CERN reject my paper?. I think this might keep them busy for a while… We could discuss principles and all later on…]

Things I Wanted to Write About

Now that the trivia are out of my system, here is a word about what I have been wanting to write about for quite sometime, and may write in near future (not necessarily in the next post):

On the political side: The magnitude of the black money kept abroad by Indians, Why no Maharashtrian could become a PM thus far.

And, then, of course, Physics: A simple but important example illustrating how, in Physics, it is impossible to get rid of certain basic assumptions delineating the nature of your theory.
