A wish. Looking for a couple of suitable post-docs. Covid-19 in India.

1. A wish…

I wish there were a neat, scholarly, account of the early development regarding the relativity theory. …

… There are tons of material on the topic, but not a single one seems to be to my liking…. I mean, even while rapidly browsing through so many of them, they all seem to fall short—rather, so awfully short. Reason: Most, if not all of them, seem intent on deifying Einstein, and / or, the primacy of maths over physics. [Did I cover all the eigenbases? May be not. So, let me add.] … The worst of them spend themselves out on promoting the idea that coming up with good but radical ideas in physics is all about getting lucky in some day-dreaming involving some mathematical ideas. 

OTOH, The “model” for the book which I have in mind here is something like what Prof. Malcolm Longair has done for QM; see his book: “Quantum concepts in physics: an alternative approach to the understanding of quantum mechanics.” [^].

… High time someone should have undertaken a similar effort. But unfortunately, it’s entirely lacking.

… The wish isn’t without purpose. The more I study the quantum mechanical spin, the more I realize the handicap which I have of not having already studied the relativity theory.

I can always postpone the fully consistent description, following my new approach, for the QM spin. [No one / no organization has ever sponsored my research. [Though, they all are hell bent on “following up” on me.]]

However, now that I have developed (what I believe to be) a good, basic, ontology for the QM phenomena, I have begun to see a promising pathway, at least from the viewpoint of a basic ontology, from a non-relativistic description of QM to a relativistic one—I mean the special relativistic one.


2. Looking for a couple of suitable post-docs…

Another possibility I am toying with, currently, is this:

Over a considerable period of time, say over a year or so, to build a series of Python/C++ scripts/programs that illustrate the classical EM in action, but following my new ontological ideas. These ideas are for the Maxwell-Lorentz EM, but I do anticipate that these would provide the easiest pathway to integrating the Special Relativity with the non-relativistic QM.

The trouble is: I will have to get into the FDTD algorithmics too, and I don’t have the time to do it. (In case you didn’t know, when it comes to EM, the best technique is FDTD.)

Wish I had a competent post-doc—actually two—working simultaneously with me! Right now!!

One could build the above-mentioned FDTD applets, but following the way I want them to be built.

The other one could work on “FEM-ization” of my FDM code (i.e., for the He atom, done with my new approach, and yet to be published). Once he is done, he could explore doing the same with FDTD (yes of course!), and compare and contrast the two. The FEM-ization of my FDM code won’t be very highly demanding, in the sense, people have done the finite elements formulation for the helium atom, and also have implemented it in code—decades ago… But of course, they did so following the mainstream QM. It would be a fun for the post-doc to implement it using the ideas I will be proposing—shortly.

Then, both could work on the ideas for the relativistic QM. … The pace of the work would depend on what they bring to the table, and how they perform.

Fallout? If you are a smart PhD in the concerned areas, I need not provide even a hint about it…


3. Status update on my QM research:

Currently, I am typing a set of notes on the topic of the quantum mechanical angular momentum, including the spin. For the time being, I am mostly following Dan Schroeder’s notes (which I mentioned in the post before the last, here [^]). Once done, I don’t mind uploading these notes—for proofreading by you the potential post-docs. [Who else?]

While typing these notes, it has become once again very clear to me—crystal clear, in fact—as to how my “theory” for the QM spin (following my new approach) falls short. … So short, in fact. … My “theory” doesn’t just look awfully arbitrary; it is so.

All in all, don’t expect the same kind of confidence from me for the spin-related aspects as for the spin-less ones. I mean, in the upcoming document on my new approach.


4. Back to the potential post-docs:

Exciting enough?

If yes, drop me a line. Especially, if you are working with Google / similar company. I gather they officially allow you some fraction of your official time for your own hobby projects too…


5. If you are someone young and enthusiastic, say from the Pune city and all (and in general, from India):

They have relaxed the curbs. However, I have a word of advice for you.

Don’t step out unless absolutely necessary, and if so doing, take all the precautions.

It’s just a matter of a few months now…

…BTW, I am also thinking whether the government shouldn’t relax the enforced gap of three months in between the first and the second dose for the jabs. … There are circumstantial matters which indicate that a gap in between two to three months might be ideal; that three months might be too long a period. (Actually, this matter had struck me right on the day that the Central Government increased the gap from 6 weeks to 12 weeks in one, single, move. …However, at that time, I had thought it prudent to wait and watch. Now, I think I can—nay, should—share my opinon. … I also have some other points about these matters, but these are not so important. I will sure mention these as and when it becomes necessary to do so.)


In the meanwhile, you all take care, and bye for now…


A song I like:

(Hindi) ज़िंदगी आ रहा हूँ मैं… (“zindagi aa rahaa hoon main…”)
Lyrics: Javed Akhtar
Music: Hridaynath Mangeshkar
Singer: Kishore Kumar

[

Credits happily listed in a random order. A good quality audio is here [^]. … Although I haven’t seen this movie, recently I watched the video for this song, and found that I enjoyed it too. A good quality video is here [^].

… I always loved this song, esp. the tune and the arrangement / orchestration. … And of course, Javed Akhtar’s awesome lyrics. … Well, yes, Kishore does sound, at places in this song, just a slight bit… and how shall I put it?… He doesn’t sound as if he were in his best frame of singing, here. His voice sounds a bit too “broad”, and perhaps heavy, and even a bit “tired” perhaps? as if he were straining a bit?…  Even then, of course, being Kishore, he does manage to pull a great job. [It’s just that, knowing Kishore, one wants to note this aside… I know, hair-splitting, it is. … Can’t help. … Sometimes.]

… [BTW, if you are young and dynamic and result-oriented etc.: The guy in this video is Sonam Kapoor’s dad. He used to be young. Once upon time. Me too. [Though I never ever had the hair-style he displays here. A lot of my class-mates did, mostly following The “Bachchan”. Not me. […Yeah, I know.]]

… All the same, all that you’ve to do now is to wait for just a few more months, that’s all… 2021 isn’t a meme on Twitter the way 2020 was. Nevertheless, in India, we have to wait. So, just listen to songs like this for just a wee bit more. … I can tell you, from experience: The scenery, esp. the Sahyaadri’s, does stay great also well until January / February next year. (And if you really love Sahyaadri’s, well, they are there, forever…)

…So there.]

…And if you are new to this song, see if you too like it…

Take care and bye for now…

I need a [very well paying] job in data science. Now.

I need a very well paying job in data science. Now. In Pune, India.


 



Yes, I was visiting Kota for some official work when at the railway station of the [back then, a simple little] town, on a “whim” (borne out of a sense of curiosity, having heard the author’s name), I bought it. That was on 14th July 1987. The stamp of the A. H. Wheeler and Company (Rupa Publications), so well known to us all (including IITians and IIM graduates) back then, stand in a mute testimony for the same—the price, and the fact that this little book was imported by them. As to bearing testimony to the event, so does my signature, and the noting of the date. (I would ordinarily have no motivation to note a fake date, what do you say?) Also notable is the price of the book: Rs. 59/-. Bought out of Rs. 1800/- per month, if I remember those days right (and plain because I was an M. Tech. from (one of the then five) IITs. My juniors from my own UG college, COEP, would have had to start with a Rs. 1200/- or Rs. 1400/- package, and rise to my level in about 3 years, back then.)

Try to convince my the then back self that I would be jobless today.

No, really. Do that.

And see if I don’t call you names. Right here.

Americans!


A song I like:

(English, pop-song): “Another town, another train…”
Band (i.e. music, composition, lyrics, etc., to the best of my knowledge): ABBA

Bye for now.


And develop a habit to read—and understand—books. That’s important. As my example serves to illustrate the point. Whether I go jobful or jobless. It’s a good habit to cultivate.

But then, Americans have grown so insensitive to the authentic pains of others—including real works by others. The said attitude must reflect inwards too. The emphasis is on the word “authentic.” If a man doesn’t care for another honest, really very hard-working man in pain but spends his intellect and time in finding rationalizations to enhance his own prestige and money-obtaining powers, by the law of integrative mechanism of conscisousness that is the law of “karma,” the same thing must haunt him back—whether he be a Republican, or a Democrat. (Just a familiarity with the word “karma” is not enough to escape its bad—or good—effects. What matters are actions (“karma”s), ultimately. But given the fact that man has intellect, these are helped, not obscured, by it.)

Go, convince Americans to give me a good, well-paying job, in data science, and in Pune—the one that matches my one-sentence profile (mentioned here) and my temperament. As to the latter, simple it is, to put it in one sentence: “When the time calls for it, I am known to call a spade a spade.”

And, I can call Americans (and JPBTIs) exactly what they have earned.

But the more important paragraph was the second in this section. Starting from “But then, Americans have grown so insensitive to the authentic… .”

Instead of “pains,” you could even add a value / virtue. The statement would hold.

 

 

$ 1 billion in new allocations, for serendipity

POTUSes and other residents of the Imperial City do not on a very regular basis visit this blog.

I was, therefore, very much surprised to find a rare bird from that place dropping by at this blog on “Wed Aug 29, 2018”, at “03:21:26” HRS IST, i.e., early in the morning of 29th August.

In any case, “the early to rise…” couldn’t possibly be a motivation here; Washinton, D.C., and India are separated by some 9 and a half hours of time difference [^]. … Ditto, perhaps, as far as that thing about the early bird catching the worm, goes.

So, what possibly could be the reason?

I don’t know. Any guesses?


I gathered from Roger Schlafly’s blog [^] who in turn gathered it from Prof. Peter Woit’s blog [^] that

Moving through the US Congress is a National Quantum Initiative Act, which would provide over a billion dollars in funding for things related to quantum computation.

Alright. At this point, I strongly recommend that you go back to Schlafly’s post, finish reading it, and only then continue with the rest of this post.


Personally, I am not at all against the proposed act i.e. the Act.

It all is American money, first thing. And, the rest of the world sure knows for a fact that America has huge amounts of money. They could easily fund even just serendipity [^]!

So, from this point of view and motivation, $ 1 billion actually looks like a paltry amount. I mean, given the fact that it all is American money anyway.


Anyway, coming back to my concerns (and those of this post), I then pursued the links to the QC skeptics that Schlafly helpfully provides in his post.

The Quanta Magazine article [^] covering Prof. Kalai’s work was something I had already browsed some time ago, when it had first come. This time around though, I showed the good sense to actually pursue the links given in it, especially the links given in this passage:

“… a loose group of mathematicians, physicists and computer scientists [have been] arguing that quantum computing, for all its theoretical promise, is something of a mirage.”

Hmmm… Mathematicians, physicists, and computer scientists….

I am not sure if the “physicist” (Wolfram) is indeed arguing against QCs in the linked passage [^].

The “computer scientist” (Prof. Oded Goldreich) has some remarkable insights into the nature of the very theory of QM itself [^]. However, his note is very brief. It also seems to be a bit dated. Looks like it is an informally written and early thought on this matter.

But it was the “mathematician” (Prof. Leonid Levin) who, I found, was truly distinctive [^]—despite his being a “mathematician.”

OK, the way it happened was this. It was only when I landed at Levin’s page that I came to know that this write up was coming from him. Now, his name did give me something like a vague ring—a vague feel that this guy was, may be, a neat / original guy or something like that. But I couldn’t place him immediately. So I did the right thing. I just ignored who he was, and focused on what he had to say by way of regarding the QC as a “mirage.”

There was little trouble getting hooked on to Levin’s write-up. The writing, I realized, was very tight and wonderful. Just how wonderful? I would consider it a great achievement if I ever manage to write something that is written even half one-tenth as well as how Levin writes here. … Want to see a sample? I (anyway) can’t resist the temptation to copy-paste this particular passage:

2.2. Quantum Computers

QC has n interacting elements, called q-bits. A pure state of each is a unit vector on the complex plane C^2. Its two components are quantum amplitudes of its two Boolean values. A state of the entire machine is a vector in the tensor product of n planes. Its 2^n coordinate vectors are tensor-products of q-bit basis states, one for each n-bit combination. The machine is cooled, isolated from the environment nearly perfectly, and initialized in one of its basis states representing the input and empty memory bits. The computation is arranged as a sequence of perfectly reversible interactions of the q-bits, putting their combination in the superposition of a rapidly increasing number of basis states, each having an exponentially small amplitude. The environment may intervene with errors; the computation is done in an error-correcting way, immune to such errors as long as they are few and of special restricted forms. Otherwise, the equations of Quantum Mechanics are obeyed with unlimited precision. This is crucial since the amplitudes are exponentially small and deviations in remote (hundredth or even much further) decimal places would overwhelm the content completely. Peter Shor shows such computers capable of factoring in polynomial time. The exponentially many coordinates of their states can, using a rough analogy, explore one potential solution each and concentrate the amplitudes in the one that works.

… Damn it! Not a single word out of place, and, not a single relevant consideration missed!

… If this piece is typical of Levin’s writing, then I must say that the rest of us (outside of his specialty) have been missing something remarkable.

Go, continue with the fun. Even the title of Levin’s next sub-section—“Small Difficulties”—is delightful.

Oh, BTW, Leonid Levin is one of the two people who independently discovered the existence of the P-vs-NP issue [^]. …


It all still does not mean that I am against the act i.e. the Act.

I do in all sincerity believe that they are far more likely to fail achieving even “just” the quantum supremacy, than succeeding in it. But realize that quantum supremacy is just the potatoes here. The meat is: breaking the RSA codes. No one is talking about that part. (Meaning, I feel sure that the meat is even far less likely to be achieved, ever.)

At the same time, I also equally sincerely believe that, all things considered, the amount ($ 1 billion) is not at all something on which Americans would (or even should!) get worked up a lot.

OK. Some may experience dismay over the fact that more Democrats than Repulicans are going to get employed as a result of that funding.

However, none could challenge the fact that most people who stand to derive benefits here would be your typical scientists and engineers: middle-class, law-abiding, hard-working citizens who place high value on education and culture, why, sometimes even on reason!

Even the worst critics of the bill would agree that these people wouldn’t make for all that bad a company for a dinner. As guests, they may not make for the most interesting lot, but they also wouldn’t spoil the mood of your party with some off-color remarks. Also, it is a fact that while in office or lab, they would work sincerely on their goal—even if the goal is that of building a QC that works!

So, given all that, the money they are asking for isn’t a complete waste—you couldn’t call it “pork,” so to speak.

And then, you can never tell what accidental and unintended discovery might come out of it all. [^]

Yes, American science is weird—not to mention the American post-graduate (called “graduate”) education, and also the American engineering (especially the kind that is practiced on either coast, but especially so in California). Trends in American education, science and engineering are all dominated by all kinds of fads, entrenched viewpoints, prejudices and whatnot—except for reason. (I should know!) The QC is, from this viewpoint, just another fad.

Yet, it also remains true that sometimes, after thoroughly checking equipment, removing pigeon-nests from it, and even cleaning out the accumulated droppings, the signal still remains there—it refuses to go away [^].

Yes, 55 years is a long time to have passed since then, but still, somehow, it does seem to me, speaking in overall terms, that $ 1 billion in new allocations would not necessarily be a bad thing, so to say—you couldn’t possibly call it “pork.”


Another thing. The way I really see it is this way: The more they try to build a really powerful QC and fail—as they are bound to—the better become my chances of collecting a Nobel or two. Whaddaya think?
