Here are a few (almost) random points…

1. Economics:
Can Swami (of Swaminomics) explain to me in simple enough terms the following phenomena:
1.1 If, at the most basic level, stock investments are done by keeping in view the earnings through dividends, how come Bajaj Auto shares used to be traded at more than 100 times or so during Indira Gandhi’s rule?
1.2 Similarly, for the other cases, in today’s context.
1.3 Clarification: I am not for greater control to rectify the situation.
1.4 There is a dominant streak of pragmatism in every “pro-business” “defence” which I would rather someone exposed—without proposing more government interventions.
1.5 Indeed, I think the extent that the market is overpriced precisely serves to reveal the extent of the government intervention in economy.
More on economics, later… I have an idea for modeling of certain kind of basic economic issues.

2. Sathya Sai Baba:

So much has been written about him that his case has thrust itself into being a curiosity for me for quite some time. … I wouldn’t mind visiting his Puttaparthi ashram (or some place similar) provided he can talk to me on a 1:1 basis. And it would be OK even if this occurs in front of thousands or lakhs; I hardly care for that aspect. But should his weighty followers and he himself at all come to thinking of allowing this to happen, here are the opinions (or the “baggage”) with which I would go to him:
2.1 First and foremost, I don’t believe that he is a reincarnation of the Sai Baba of Shirdi, full-stop. From what I have read of the original Sai Baba, this claim is a complete impossibility—regardless of whether Hirabai Badodekar (and the then Rashtrapati Bhavan) agree with my assessment or not, and whether APJ Abdul Kalam, Shankarro Chavan, Ashok Chavan, Shivajirao Patil Nilangekar, Jayant Patil, Sonu Nigam, Sachin Tendulkar, Suchitra Krishnamurthy agree with me or not.
2.2 I don’t agree with his critics that all he is can be reduced to a few magicians’ tricks. (And, I don’t concern myself with everything that has ever been written, said, or suspected about him on the Internet or on the BBC.)
2.3 He might have some spiritual powers and he could possibly be using it in a way that his followers feel blessed, or at least, relaxed. … Not enough of a reason to take his claim of being Shirdi’s Sai Baba very seriously.
2.4 I am not a materialist in the tradition of the so-called “rationalists” of India (the leftists and left-leaning intellectuals included).
2.5 He shouldn’t expect me to even bow down to him as a precondition of my meeting with him. If he can meet me, as I said, one-to-one, I am eager to talk to him. It won’t take even five minutes for me to place him better (than what I have above) in a personal meeting.
2.6 And, oh yes, I wouldn’t at all mind bowing to him in a manner befitting his place should he want to see me. The point is: He should not mistake my physical bowing with anything else—esp., my acceptance of all his ideas and all his claims—that’s all. Indeed, I would be very neat, just like all his followers, should I go and see him.

3. Indira Gandhi
It’s remarkable that post-Vajpayee years, remembering her is, on the whole, a subdued affair. … I mean I didn’t see full-page photos in the newspapers, and there weren’t huge cut-outs towering over buildings either… All this was welcome, in a way. After all, there still is a huge gap left between remembering her and remembering Lal Bahadur Shastri.

And, BTW, I really can’t remember her without also remembering Durgabai Bhagwat—the real iron lady between the two, if you ask me. … Again, it’s not that I agree with every position that Bhagwatbai ever took in her life…  [And, is issuing such clarifications really necessary?] But, as far as I am concerned, Bhagwat’s principled defence of Freedom during those difficult years of Emergecy was enough for me to conclude that this, in fact, was actually the case….

And, indeed, what quote could they at all find to bring out the supposed “greatness” of Indira in those recent newspaper ads? If you read through it, it’s plain and obvious that such quotes could fit in the mouth of any third-class dictator in any of the third-world countries—all that the speech-writer would need to have is some education in one of those Christian missionary schools, and he would be well on his way to utter what Indira Gandhi, we were especially seriously reminded, did!

Which brings me to another sub-point: Has Barkha Dutt lost her original fire these days? … First, there was this change of the mix of topics as soon as they had that deal with MSNBC or NBC or so. That, by itself was bad already…  I mean, Barkha would get the heat up on some topic, and suddenly that entire topic of discussion would get mixed quite incongruously (and in following with all the worst trends of the Tame Americans) with some other topic that was decidedly luke-warm. (Luke-warm, mind you. Not cold.) … And then, in such a process, the whole tempo of that hot topic would be entirely lost. Plus, they also  reduced the time spent actually debating—not just the content but also the format… All this was bad by itself… But then, esp. since her becoming a Padmashree or so, this lady seems to have lost that fire to confront the government uncomfortably that she used to have. … Or is it the case that she was a Congresswoman in disguise all the time, and that we saw that side of hers only because BJP+ was in power? Any thoughts, Barkha?…

Not that she should be the hanging point for all our worries… That’s not the idea here. If she is tired or bored out of fighting it out, she is entitled to a rest… But then, the decent way to do this is to retire from all that debating—not to dilute it to the extent that one doesn’t even feel like turning the TV on Sunday evening at 8 PM…

Some of the songs that I like:

(Hindi) “yehi woh jagah hai, yehi woh fizayen..”
Singer: Asha Bhosle
Music: O. P. Nayyar

[... More, later!]

I have updated my Web site: http://www.JadhavResearch.info

The version 2.0 of the Web site is still under construction. However, I have added a ballpen sketch and a couple of portraits (all, from my undergraduate COEP days—more than 25 years ago). See here: http://www.JadhavResearch.info/personal.htm

Since I am already posting something in the art category, this post won’t have the usual end-section of a few songs that I like…

And, from next post onwards, I have decided to make it a bit flexible. It will be anything from 1 to 5 songs, and further, I am also going to begin using a random number generator so that the selection will be random—unless I state otherwise. … You see, no matter how hard you try, the selections do naturally tend to have a pattern to them. The only solution is to make a fairly comprehensive list of songs and have a program pick a few up”at random” (I mean pseudo random number generators, with time of picking the songs up serving as the user-selected seed)…

I successfully defended my Ph.D. thesis yesterday.

The presentation got somewhat lengthy; it went on for about 1 hour 15 minutes. (I explained a bit more in detail on the fly, following the audience reactions.) This was followed by a formal Q & A session of about 45 minutes.

My family and friends were among those present for the event. Many of them expressed it to me later on that the Q & A session seemed to them to be a bit more rigorous than what they had expected. However, this had never crossed my own mind during the event. Throughout, I thought that it was alright—this was a Ph.D. defence. (It was the first PhD in our family, including our extended family. Also, the first PhD from our class of B.E. Metallurgy; most of my class-mates have gone into business, management, or software development, rather than into research.)… In any case, not even for one moment during the event did I doubt that the outcome would be anything other than the positive.

But yes, the Q & A session did not slip into a mere formality, and I am happy about that (and grateful to the examiners for that).

All in all, a wonderful event—a unique event of my life!

A couple of days ago, the HBL Web site provided an excerpt on concretization and reduction. It was from Jean Moroney Binswanger. [Update on Sept. 16, 2009: I am taking the liberty to copy-paste the excerpt in toto here.]

I have thought about the issues Damon Cole raises, and have a somewhat different perspective. Some ideas:

1) Concretization and reduction have two different purposes.

The purpose of concretization is to clarify the meaning of an idea (a concept, phrase, or proposition) by using perceptual concretes. Although examples are the archetypical form of concretization, there are many other forms. These include descriptions, diagrams, models, and analogies. Note that it is possible to concretize a false or invalid idea.

The purpose of reduction is to validate the idea by tracing it back through the chain of reasoning to its basis in perceptual reality. It is not enough that it connect to perceptual reality “somehow” or even that it be concretizable. Every step in the process has to be validated.
—  Jean Moroney Binswanger

Since I seem to differ from her view of reduction, I would like to write a bit about it.

(BTW, the reason I have not joined HBL, even if there is a free trial subscription on offer currently, is that many topics on the list wouldn’t be of direct relevance to me, and yet, since the quality of the discussions appears to be fairly good, subscribing might have a distracting effect on me. As it is, I fall so woefully short of time… Several books and articles to be finished, immediately…)

- – - – -

On the issue of concretization, I think I agree with JMB. Concretization is the process of identifying what kind of concretes are subsumed under a given abstraction. This may involve examples, diagrams, etc.

However, reduction is where I seem to differ from JMB’s view/description (as judged by the excerpt that was given).

Given below are my thoughts (without being able to find any time to make any references).

Reduction is a process of simplifying a given abstraction. Consider the following examples of reduction. (In other words, let us concretize the process of reduction.)

• (A) Simplification of Form (the easiest form of reduction)
  • e.g. 42/8 reduces to 21/4.
  • e.g.
• (B) Componentization (my word!), i.e. simplification via an identification of a “has-a” relationship (i.e. a Whole-to-Part relationship)
  • e.g. Upon dissociation, reduces to and
• (C) Specialization, i.e. simplification via an identification of an “is-a” relationship
  • e.g. Effecting the separation of variables, the partial differential wave equation reduces to the Helmholtz equation

A Few Notes:
(i) The “is-a” and “has-a” relations are often nicely explained in the OO programming books.
(ii) There is no suggestion that the above (A) through (C) categorization gives an exhaustive scheme.
(iii) Science provides conceptually easy examples, but examples from humanities are not as neat to classify. For example, consider this usage: “During those summer vacations, her life had been reduced to eating, reading and sleeping.” (Technically, this would be an example of componentization. But it is not as clear a case as reducing all water exclusively to hydrogen and oxygen. The list of the parts which comprise “life” is incomplete here, as often is the case.)

Notice, we did not have to go down to the level of perceptual concretes in all our examples. When it comes to reduction, the relation to perceptual concretes is important only in the ultimate sense. It is directly relevant only if the concept being reduced itself is a fairly low-level one so that the components or specialized cases that it refers to must turn out to be perceptual concretes. So, it is to be emphasized that, as a process, reduction is not primarily about identifying meaning of a concept; it is about establishing conceptual relationships from the more complex to the more simple.

Speaking metaphorically, the focus in concretization is on the final destination itself; in reduction, it is on the journey—the particular path-way. In either case, the final destination need not be perceptual concretes. (Given Ayn Rand’s works, one assumes that the “ultimate destination” is going to consist of some or the other perceptually evident concretes.)

Of the two, reduction does tend to appear more formal and rigorous because (i) the easy examples of reduction do seem to involve deduction, and (ii) of the two, it is reduction which is amenable to being summarized. Concretization, by its nature, involves elaboration or expansion of a sort. People often associate rigour with terse formulations, deduction, symbols. Therefore, reduction seems to involve rigour whereas concretization doesn’t seem to. However, do notice, deduction is not the only process involved in reduction. And, concretization does take real work

In the fallacy of “reductio ad absurdum” the real error occurs not in reduction but in the major premise. This much is true. But this does not make reduction any more error-proof than is concretization. Errors are possible in either case.

Observe that as a general rule, in the process of reduction, there occurs a concomitant reduction of scope. Forgetting this can easily lead to errors, and so can making it out as if there is no such a reduction. For example, asserting that Indian culture equals Hindu culture involves an error of reduction. (The error involved in reducing India to Indira/Sonia was/is another blatant error.)

An aside about “Western reductionism.” I do not at all like that term; it’s an anti-concept. (Has anyone ever offered a rigorously valid definition of it?) At the same time, also remember that the mind-body dichotomy (MBD) has always been, unfortunately, a very prominent part of the Western culture throughout its history. The MBD involves nothing but an erroneous reduction of Man to either the mind without the body or the body without the mind.

Exercises (if you care for one or two):
(i) Find examples of improper reduction in the context of today’s American cultural context
(ii) Identify what kind of error is involved in the fallacy of frozen abstraction (see Ayn Rand, “Philosophy: Who Needs It.”) Is it an error of concretization? of reduction? Something else?

- – - – -

The reason I decided to write this post is because I wanted to clarify what I mean when I say something like: “…[under certain circumstances] FAQ reduces to the Monte Carlo method.” In all such cases, I certainly don’t mean to say that FAQ is based on the Monte Carlo (—a position seemingly implied by JMB’s piece). What I mean to say that the Monte Carlo may be considered a special case of the FAQ. … In mechanics and physics (not to mention engineering), this seems to be an acceptable usage… But if there is a correction to be made, I would like to know about it.

Carol White’s Book Involving Electromagnetism and Potential Theory

This is about the following book:
Carol White , “Energy Potential: Toward a New Electromagnetic Field Theory,” (with essays by Bernhard Riemann trans. from German by J. J. Cleary, Jr.), Campaigner Publications, New York, 1977.

I ran into it in mid-August 2009. It can be downloaded for free from here: http://www.archive.org. (Search for it at this site.)

Unfortunately, I could not go through all of it. (One reason is that in order to do so, I will have to take a paper printout of it (my reading habits are old-fashioned), and somehow that has not happened so far.) Yet, I find that the book has been written very interestingly.

In our times, there is this widespread tendency to write in a self-censoring way so as not to offend anybody, to try to be as sensitive to as many desires (even whims) of as many other people as possible, to try to be “politically correct” even while writing for/on issues of hard science. Against this background, Carol White’s book comes across as a breath of fresh air. (And to think that it was published barely 32 years—one generation—ago!)

Of course, I don’t think I am going to concurr with every idea or opinion which she expresses in this book. But that hardly matters.

I still strongly recommend this book because of its directness, its freshness, its willingness to pick up philosophical issues for examination right while working through the things scientific…. All of this is so unlike our present times. Also, the engaging style in which the text has been written… You might pick up virtually any page at random and see what I mean. For that one reason alone—call it the “style” of the book if you wish—it makes for a very interesting reading.

It’s precisely because the author writes with such a passion, candor and directness, in such an opinionated manner, that her content becomes so very interesting to read.

And that was the biggest point I wanted to make here.

[And yes, Riemann's essays might form an additional/major attraction for some of you.]

Professor Patrick Suppes’ Papers on Quantum Mechanics

I have a confession to make about an omission that simply happened while writing my PhD thesis. … Let me begin at the beginning.

I had developed the essentials of the FAQ approach years before 2002 when I began the effort to get myself registered for a PhD (starting with IIT Bombay). My ideas had been developed independent of Professor Patrick Suppes’ publications [see here].

Later on, sometime during the course of my PhD work, I did notice Suppes and de Barros’ papers. However, for some odd reason, I completely forgot about these when I actually came to writing of my thesis.

I intend to correct this when I write my journal articles. (Some of the preliminary thoughts for these are given on iMechanica here.)

Of course, it’s not a very major issue because, once again, just like QMC, Suppes & de Barros’ work is not at the base of my method. Indeed, there are some very important differences between my approach and method on the one hand and theirs on the other. … For the time being, let me leave it as a simple exercise for the reader to find out what these differences are, starting with their 1994 papers [here and here ]. Indeed, I might have a critical comment or two to make w.r.t. their work, speaking from the physics viewpoint…

Here, a clarification is in order. Though I have been very much interested in philosophy, it is not my field. It’s sort of a hobby or a special interest for me. Indeed, most of what I know about philosophy has come out of the works by Ayn Rand, Peikoff and other Objectivist philosophers (esp. Peikoff’s course on Western Philosophy), and of course, many other readings on general philosophy, notably including two/three different translations of Aristotle and Plato (select but fairly represenative passages of each), several texts on Greek philosophy, and also some university texts and some popular books like the one by Will Durant. On the Indian philosophy side, my reading includes translations and commentaries on the Upanishads, Geeta, and numerous other books. Also, the general Enc. Brit. articles for all philosophic traditions/schools. All in all, not much.

So, I don’t think that I can place Professor Suppes’ specifically philosophic positions in context all that well… In any case, I cannot comment anything meaningful about this aspect of his work in a serious research work.

But, frankly speaking, the most relevant of his papers (circa 1994,  discovered by me sometime after 2002) can be easily read by anyone. They deal with the physics of QM rather than philosophy as such.

So, there’s an exercise for you, if you want one.

Three Songs I Like (as decided last time; see below)

1. (Marathi) “varyaavarati ghet lakeri, gaat chaalalyaa jal lahari…”
Singer: Suman Kalyanpur.

2. (Hindi) “kuchh dil ne kahaa, kuchh bhi nahin…”
Lyrics: Kaifi Aazmi

Music: Hemant Kumar

3. (Hindi) “kai baar yun bhi dekhaa hai…”
Lyrics: Yogesh (?)
Singer: Mukesh
Music: Salil Chowdhary

One of my recent muses is the title question of this post. … Allow me to explain.

As I have pointed out a few times in the past in this blog and also elsewhere, I have discovered a way to resolve the quantum wave-particle paradox. See my slides and papers here. Soon later on, I began calling the new approach by the name “FAQ,” which is short for: fields as quanta. That is what the “FAQ” in the title of this post refers to.

Before making my claim, of course, I had done an extensive literature search, almost none of which was cited in the abovementioned papers, simply out of the space limitations of a conference paper. But the search was there. One of the things I had quickly browsed through, during this search, was the literature on QMC—short for Quantum Monte Carlo.

In recent weeks, I decided to search once again. It must have been the n-th occasion that I was searching thus. This time round, I was reading more closely the papers, and so ran into some interesting passages in a few early papers (circa 1975) by Professor James B. Anderson of Penn State (USA). In some of these papers, Professor Anderson indicates that Metropolis, Ulam and John von Neumann had stated in one of their early papers (in late 1940s) that the idea for something like QMC had already occurred to the great physicist and Nobel laureate Enrico Fermi.

Curious, I immediately wrote him an email, and promptly received the directions to look up his new book: “Quantum Monte Carlo: Origins, Developments and Applications”. The relevant pages of this book can be browsed at Google books [here]. This book is a researcher’s dream come true. Original papers tracing the development are hand selected, and brief introductions to each provided. (These introductions written with expertise and yet remain accessible to a “lay reader” like me.)

It’s enough to browse the first few pages of Anderson’s book to realize that Schrodinger himself was right up there, thinking about these ideas (and also publishing them in journal papers) right in 1935.

Thus, QMC has… what’s the word here? precedents? antecedents? … Whatever. I will use the term “precedents” here. So, QMC  has two independent lines of precedents, both traceable to famous people (Nobel laureates), one going as far back as to 1935, to Schrodinger himself. The other line goes back to late 1930s and early 1940s to Fermi. (I forgot my tracks on the Internet or in the books/papers here, but will add links to them later on.)

Very deeply interesting, this all is. Also, even satisfying in a way!

However, all my reading of all such material tells me that all the precedents to the modeling of Schrodinger’s Equation (SE) using ideas such as random walks or Monte Carlo involve the imaginary time—not the real time. (Refer to Anderson’s excellent book and papers to know what this means.)

My approach, in contrast, involves the real time (and the real space—not a configuration space).

It might seem amazing that Einstein worked on both the photoelectric effect and the Brownian motion in the same year 1905, and yet didn’t think of extending the second to explain the first. Even more amazing is the fact that both Schrodinger and Fermi thought of using the second to model quanta, but never thought of doing so in the real time.

It is for these reasons that I conclude that QMC cannot be said to have the priority over FAQ. In other words, my claims are valid.

This post is to bring the matter to your careful and serious attention. If you have any [proper] evidence contrary to my conclusion/claim, then kindly do drop me a line or provide the links.

[BTW, note, links like this may be good otherwise, but are not detailed enough to be of help in this matter.]

- – - – -

A few clarifications/asides:

I am not at all interested in any sort of a priority battle. But one likes to be as direct as is possible in communications. The purposes this policy serves are things such as: precision and economy in thought; propriety in the allocation of intellectual credit where one is due.

Interestingly, after submitting an abstract to an upcoming international conferences in India, the reviewing committee noted to the effect that “direct claims” such as what I was making could not be entertained.

To say that I was surprised would be an understatement. It was nothing less than shocking. … Of course one is supposed to be as direct as possible in all communications of this kind. Indirectness might have its allure in poetry, esp. of the romantic sort. Consider here the beauty of: <Hindi>”Kyaa Kehnaa Hai, Kyaa Sunanaa Hai…”</Hindi> … You know what I mean—literally…. But trying to use it in science/research? (LOL!)

So, one tries to be direct. And, one remains open and available (i.e. active-minded) to correct oneself—if a correction is necessary. It is in this spirit that I make all my claims. After a conscientious and as wide a literature search as possible. But directly, as directly as possible, thereafter. … Sigh… Not all folks in India know or understand or support this way of approaching science!

Anyway, to return to more interesting matters than them (and their science/engineering), let me know if I am understanding QMC in a wrong way and/or making a wrong claim somewhere in my research. I would appreciate being kept corrected—if one is necessary.

- – - – -

And, while quoting Javed Saheb’s poetry (which also is a song), it occurred to me that it might be a good idea to start jotting down a few songs that I like after every post I make. (This idea traces its origins to Jean Moroney Binswanger’s advice [here] to everyday jot down three good things—major or minor—that happened to you on that day…. Well, three per day is too much, but three per post isn’t a bad idea to implement).

Accordingly, here I begin, right away. Three poems/songs/tunes/musical compositions I like (of whatever type/genre, for whatever reasons, from whatever language I know, etc., more or less at random, out of hundreds of such):

1. <Hindi>ye raate ye mausam nadi kaa kinaaraa…</Hindi> (Kishore Kumar)
2. <Marathi>jan paL bhar mhaNatil haay haay…</Marathi> (Lata, Bhaa. Raa. Taambe.)
3. (Words not necessarily exact)<Hindi>chhaayee barakhaa bahaar, kare jiyaraa pukaar</Hindi> (Lata)

An important note about the third song: As far as I can make out, (and I am confident about it), this song is in the “raag” “bhairavee.” The reason I am so confident is because I once heard an unforgettable “jugalbandi” of Pandit Bismilla Khan on “shehnai” and Mrs. Rajam on violin in “bharavee”. It was an especially memorable performance because it was the first time ever that I had really appreciated a piece of the Indian classical music. (As a rule, I find it boring—but always with notable exceptions. (Also Western classical—most of it, too, is boring.)) They had announced the “raag” at that time, it was “bhairavee.” I had observed, right then, that this song of Lata (which I quote above) was exactly like that “raag” and vice versa.  (The venue was the Open Air Theatre of IIT Madras, when I was a master’s student there at that time.)… The reason to share this all side information is to emphasize doubly and triply that the song I have in mind here is not the “aayi barkhaa bahaar…” by Lata and Madan Mohan. Neither is it any of the other “aayi barkhaa bahaars…” that are listed on Google within the first 30 pages. And of course, it is not that Salil Choudhary’s unforgettable “o sajanaa, barakhaa bahaar aayee” (which is not in “bhairavee” anyway.)

… Yes, the song I have in mind is for real. It exists. But I don’t recall any of its other credits (like the film, the lyricist, the music director, etc.) except for the fact that it’s been sung by Lata and that it is in “bhairavee.” (And yes, at least one member of our family could distinctly remember that there is such a song (despite the fact that I am not a good singer), though they too can’t recall its film etc. … Please do let me know if you find it.

I have begun reading J. S. Bell’s “Speakable and Unspeakable in Quantum Mechanics.” … I began by following his advice to the lay reader that one should begin with paper nos. 18 and 20. (The book is a collection of his published papers.) I was delighted to find the following quote right on the second page of paper no. 18:

“…So I think it is not right to tell the public that a central role for conscious mind is integrated into modern atomic physics. Or that ‘information’ is the real stuff of physical theory. …”

Unusual.

I never take anyone’s comment about QM very seriously. … I might have heard/read a lot about Bell; still, I am going to read his book as if I were the first guy to do so. … Works for me. (The words to describe this attitude are: “first-handedness” or “independence”. (And yes, they are very easy…) )

I will keep you posted if I find something extraordinary… But, frankly, I don’t expect to go through some of his more technical papers at all. I guess I already know what it all would boil down to.

He further states:

“… de Broglie in 1926… answered the conundrum
wave or particle?
by
wave _and_ particle.

But by the time this was fully clarified by Bohm in 1952, few theoretical physicists wanted to hear about it …

The de Broglie-Bohm picture…, and indeed, I think any sharp formulation of quantum mechanics, has a very surprising feature: the consequences of events at one place propagate to other places faster than light. This happens in a way that we cannot use for signalling. … For me this is the real problem with quantum theory: the apparently essential conflict between any sharp formulation and fundamental relativity…”

Well, I don’t get this passage. If this issue had been fully clarified in the de Broglie-Bohm formulation, then why does a real problem still linger on in it? Apparently, Bell, like all Brits of post-Bohm times, was too enamored by the Bohm formulation to think this way about what he was saying…

“It may be that a real synthesis of quantum and relativity theories requires not just technical developments but radical conceptual renewal.”

How true!

Bell continues…

“In my opinion the following point cannot be emphasised too strongly. When we work out a problem in wave mechanics, for example that of the precise performance of the electron gun, our mathematics is entirely concerned with waves. There is no hint in the mathematics of particles or particle trajectories. With the electron gun the calculated wave extends smoothly over an extended portion of the screen. There is no hint in the mathematics that the actual phenomenon is a minute flash at some particular point in that extended region. And it only in applying the rule, relating the probable location of the flash to the intensity of the wave, that indeterminism enters the theory. The mathematics itself is smooth, deterministic, ‘classical’ mathematics… of classical waves.”

My comments:

First of all, what did Bell think stood for—the classical wave-field variable? … That’s just one example of how even good physicists unwittingly bring unexamined or traditional views to bear on a topic under discussion.

But more than that, I think the issue here is deeper.

If you take care to develop and/or understand a physical view for the mathematics (such as what I have developed), then there is no confusion as to what is it that the mathematics is concerned about.

And thus, I want to note that among the many things that must be understood clearly by physicists, one is that mathematics calculates and physics describes, and the two endeavors are and must be kept separate (even though both the things may be done by one and the same person—as often is the case in mathematical physics).

More, later. But yes, by and large, and comparatively speaking, Bell does seem to have been far more reasonable than so many researchers/commentrators of physics of his time (and those of earlier times as well!).

If someone know books/articles dealing with the meaning of the concept of potential in physics (or concerning the physical bases underlying the energy methods of mechanics) then I would very much appreciate getting to know about these.

Please note, when I say physical bases, I mean physical bases—not “simpler/prior mathematical notions/procedures, very easy to work out.” Thus, my query is for material that is primarily conceptual, not mathematical. (As an aside: Mathematical material on this topic is so easy to get that, speaking metaphorically, a stone’s throw would yield a dozen references if not 1200. … But I was talking about treatment that is not exclusively mathematical. Essentially, a counterbalance to La Grange is what I was looking for.)

Also note, by potential, I do not mean the limited context of electromagnetism (EM) alone. Indeed, if you ask me, energy methods are far more valuable in mechanics than in EM primarily because the (statically) indeterminate case is so easy to run into, in mechanics. The momentum approach isn’t, therefore, most convenient.

I have already browsed through Lanczos (The Variational Principles of Mechanics) and find it helpful. Just the right sort of book, even though if I were to have the material to write this book, I wouldn’t present it in the order that he does. … Anyway, apart from this book, is there any other source? That’s the question I have here.

I might as well mention here that for my purpose here, Goldstein (Classical Mechanics) has been a big let down (both in terms of the contents as well as their ordering) and so has been Weinstok (Calculus of Variations). I remember having browsed very rapidly through Morse and Feschback a few years back, but without finding anything directly useful in this context.

So, there. Any indicators/links other than Lanczos would be very much appreciated. If there aren’t any, I guess I might myself write up a research article on this topic.

Thanks in advance for any links/references.

There has been a flurry of activities… I barely find the time to list them here…

1. I have conducted a 7-day course on FEM for a group of about 20-25 working engineers. The trainees were a mix of both highly experienced engineers (with 2 to 3 decades of work experience) and 4–5 IIT trained MTechs. All of them came from a couple of government organizations active in civil engineering design and research.  The course, though nominally meant for 7 days, actually ran into almost 10 calender days. It was a big success. … In conducting this course, a very senior faculty-member from IIT Bombay had also very graciously joined me for a couple of days. (I esp. appreciated it because, these days, normally speaking, I find IIT Bombay hateworthy—for a very good set of reasons.) The course happened in end-May—early June. More on it all, later…

Both these organizations were government organizations. I am still looking to receive my paycheck. However, being government organizations, it is guaranteed, in a way, that the check will certainly arrive some day… (How I wish the organizations were not being run by the government!)

2. About my earlier undergraduate course on FEM at COEP. I finished teaching it. And, also grading the students for their performance… There are times when one wishes god existed so that he could be on one’s side in performing tasks like these—I mean, grading… In the end, one makes as best choices as possible, though!

This course, too, was a wonderful experience for me, and, if informal student reactions is anything to go by, it too was a great success.

The students themselves took a lot of interest… There was a query, rather, a couple of them, right at the beginning of the course, which had caught me not just “unprepared” but actually “ignorant.” … Somehow, I had always associated the word “ignorance” with the word “disease” (not to mention “darkness” etc.)… Little did I know that the same word could be associated, in a way, with “joy,” too!

Anyway, despite such brilliant querries, I had enough of a “teacher” in me to sail smoothly through the course… More on those queries and all, later. (I will surely share them, but later on… You know, this is supposed to be a real *rapid* update.)

3.  More serious. All concerning Congress (I) and Times of India… (If you know me, you expect this off me.)

Kapil Sibbal, my favorite debater on TV (and if I let my emotions interfere, more favorite than his enemy Arun Jaitley), has recently become HRD Cabinet minister. Our PM ManMohan Singh, the Cambridge graduate, has a way of learning, albeit late—he should have removed Arjun Singh long time back.

Immediately after assuming his charge, Kapil has done something about 10th standard examinations. … Now, I do have a lot to say against exams and ranks; e.g., see my informal writing on my Web site (and also the earlier entries on this blogs)… Yet, this decision left me, say, wondering.

BTW, why don’t I see a single article from Ramchandra Guha (of Bangalore) or Prof. Dipankar Gupta (of JNU) on this topic—whether the 10th board examinations are to be outright canclled or not? Or, from Gurcharan Das (yet another Harvard fellow to Kapil, apart from PC). Or, others…

My thoughts, once these two (or others) share theirs…

4. I have joined, part-time, with a Pune-based firm, a software producer in the Civil Engg. Design field, as a Consultant in software development. The domain is CAE. … Ashutosh Parasnis of PTC, Most all at Geometric Software (and sister companies like 3D PLM), MSC Sofy, and all others like them ought to find this particular development offensive. (Or, very offensive.)

I am happy about it. … And, about my work. (It does take a lot of my energy though…)

The time of transition is a time of feeling whether one is missing something… Others (many of them actually idiots) may call it a time of opportunity, a time of excitement, a time to be prudish, and so on… But if you are like me, you not only get excited and try to make best of your opportunities but you also tend to grow apprehensive—about the direction in which all the development goes… With my first corporate training program in the CAE field already delivered, and now with this opportunity, these sure are times of transition for me… I have waited long for things like these to materialize.

These opportunities have come after going without a job for 6–7 years, after running my own Web site for 3-4 years, and after running my blog at the Harvard-based iMechanica.org for roughly two years. Clearly, lack of information (including that found on the Internet) couldn’t have been the cause why I didn’t get such opportunities before… Clearly, the reasons had to do with politics—including international politics.

And that’s why I am worried as to what game of international politics I am being subjected to… Why should I get encouraged, by the world (the bold-letters is not an accident), to do in-depth research in Civil, but not in Mechanical…

Hey, Ashutosh (Parasnis, of PTC, working under a lot of BA types in USA), do you have answers? I want to ask the same question to yet another Harvard graduate running Geometric Software–do you have any idea why I was going without job for all these years even when you kept paying Brahmins and Reserved Category alike for all these years? Was the word “competence” ever a part of your processes?

5. That brings me to one more item of news that I consider as nothing but positive and encouraging for me… Mr. Narendra Jadhav has finally given up the much coveted position of being the V/C of University of Pune. Yes, he is gone! Finally!! But not before awarding himself (if the printed rumour is evidence to go by), 10/10 points for his grandiosly poor performance on this particular job.

Hmmm….

(Sometimes, Naryaa, one doesn’t even have the energy left to LOL! But one wishes to!! Honestly!!!)

Let me get back to the business of living my (difficult to live (on several counts)) life though!

Pandit (i.e. Mr. Pandit Vidyasagar), since you were mentioned this morning in ToI, for selection in some committee etc., let me make this public. (And I have already let you know of my feelings—no matter what consequences.)

I think you will make for a very poor V/C. Of, University of Pune—as poor as Mr. Narendra Jadhav was. (One has read about how the Mahamahopadhyay ran the University…)  (Cost? I could give up my PhD degree, though, I already know, this isn’t going to be the case even if I do oppose incompetent Pandit’s nomination/application.) He may add “feathers” to his (possibly existing) cap by being committee member here and there… But he should not be made the V/C… As a student (still) of University of Pune, this is what I wanted to say—and let the (rest of) the world take notice.

6. I also attended a funny interview on being a teacher of Mechanical Engineering in University of Pune… The interviewers did not bother introducing them (I was the first person to be interviewed), and when I enquired about them, they over-emphasized the title “Dr.” in front of their names… I mean, “Dr.” Jain of Padmashree DY Patil College of Engineering in Pune, and also, one “Dr.” Ghanegaokar… That particular stress on having got a PhD was the funniest thing in that interview… If the title was supposed to generate respect in me, exactly the opposite happened.. LOL! (Mr. Jain, Mr. Ghanegaokar, I do hope that you do read this.) … As happens in such interviews, neither of them never ever came to considering (or questioning)  my ability to teach technical mechanical engineering subjects. Yet, they both were insistent on mentioning that there were some “technical” difficulties in hiring me as a teacher of Mechanical Engineering in University of Pune.

Mr. Jain, and Mr. Ghanegaokar, I pity your interviewing skills. And, in response to your emphasizing your doctorate degrees, I must say, I also pity your creativity in the engineering field…  Here, I am not exceeding my limits… I am willing to exchange our respective PhD theses, just for personal reading. I am sure you, too, will come to form the same judgment, no matter in how implicit and unacknowledged terms. And, even without inviting comparisons of that sort, one could always raise the point: Why be so bureaucratic in education, Mr. Jain? Mr. Ghanegaokar? Don’t you think you pull the standards of education down when you engage in that kind of a mindless conformance to the mindless bureaucracy which informs today’s University of Pune? You evidently conform to its mindless norms—with more than a shade of authoritativeness coming forth off you. That is, even while interviewing someone like me. Isn’t it hight time someone pulled you up for that? And nothing in this is personal… The same applies to anyone else like you—anyone else who serves only to extend the mindlessness of the University of Pune.

The fact of the matter is, there are intellectual pygmies staffing the various private engineering colleges (not to mention also the government colleges, but to a somewhat lesser extent), and they all form a closed system, and feel threatened by open talent and merit. That’s what has become of today’s engineering education under University of Pune.

Yeah! Go ahead!! Delay my PhD even further you [expletives not written not even the very first version so that the issue of their deletion does not arise, but a note must be made that they would apply most fittingly here].

7. With that said, if I still get a teacher’s (i.e. an engineering professor’s) post this season, consider it an “Allah Ki Marzi,” “Will of God,” “Devaachi Ichhaa” etc. Wouldn’t that be right, Barak—the first one?

And, why, come to think of it, since it’s July the 4th today, … why is it that Americans don’t call Barak Obama by his first name, or affectionately call him, say, BHO (like “JFK” or “Abbey” or whatever) but instead prefer to mention him by his last name: “Obama”? What gives?

Anyway, I was not thrilled when he was running for Presidency, and I don’t find him very interesting today either. It’s between him and Americans—what to call him. … One just wonders the moral distance between the American presidents of the late-20th/early 21st centuries and the Founding Fathers, that’s all…

8. All this flurry of activity of mine is OK—it gets me money, in the field I have fought years to get in—namely, CAE… But, for the time being the researcher within me is yearning to get out and get going… I don’t find any time at all for my FAQ-related research… There are so many ideas I have in there…

Oh, well… Some other time.

PS: I have already replaced my initial “brain-storm” version for this post with a better written one, and may be I will streamline this present version too, once again in a couple of days’ time… Also, I need to upload some thoughts that I had written each time I finished teaching FEM—both at COEP and as a corporate trainer…. More on this all, later. Hopefully, soon enough…
