# 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…

# Loitering around…

Update:

OK. I am getting back to working on the remaining topics, in particular, taking down detailed notes on the QM spin. I plan to begin this activity starting this evening. Also, I can now receive queries, from “any” one, regarding my work on QM, including the bit mentioned in the post below. [The meaning of  “any” one ‘ is explained below.]

[2021.03.24 13:17 IST]

Am just about completing one full day of plain loitering around, doing nothing.

No, of course, it couldn’t possibly have been literally nothing—whether of the शून्य (“shoonya”) variety, or the शुन्य (“shunya”) one. (Go consult a good Sanskrit dictionary for the subtle differences in the meaning of these two terms.)

So, what I mean to say by “doing nothing” is this:

The last entry in my research journal has the time-stamp of 2021.03.18 21:40:34 IST. So, by now, it’s almost like a full day of doing “nothing” for me.

It’s actually worse than that…

In fact, I started loitering around, including on the ‘net, even earlier, i.e., a few days ago. May be from 16th March, may be earlier. However, my journal pages (still loose, still not filed into the plastic folder) do show some entries, which get shorter and shorter, well until the above time-stamp. …The entry before the afore-mentioned has the time-stamp: 2021.03.18 19:12:52 IST.

But not a single entry over the past whole day.

So, what did I do over the last one day? and also, over a few days before it?

Well, the list is long.

I browsed. (Yes, including Twitter, Instagram, and FaceBook—others’ accounts, of course!)

I also downloaded a couple of research papers, and one short history-like book. I generally tried to read through them. Unsurprisingly, I found that I could not. The reason is: I just don’t have any mental energy left to do anything meaningful.

Apparently, I have exhausted all my energy in thinking about the linear momentum operator.

I think that by now I have thought about this one topic in most every way any human being possibly could. At least in parts (i.e., one part taken at a time). I have analyzed and re-analyzed, and re-re-analyzed. I kept on jotting down my “thoughts” (also in a way that would be mostly undecipherable to any one).

I kept getting exhausted, and still, I kept pushing myself. I kept on analyzing. Going back to my earlier thoughts, refining them and/or current thoughts. Et cetera.

In the end, finally, I reached the point where I couldn’t even push myself any longer—in spite of all my stamina to keep pursuing threads in “thinking”. I’ve some stories to share here, but some other time. …To cut all of them long stories short:

Some 12 hours after I thus fully crashed out of all my mental energies, at some moment, I somehow realized that:

I had already built a way to visualize a path in between my approach and the mainstream QM, regarding the linear momentum operator.

I made a briefest possible entry (consisting of exactly one small sketch over some 2″ by 5″ space). Which was at 2021.03.18 21:40:34 IST.

Then, I stopped pursuing it too.

Why bother? Especially when I can now visualize “it” any time I want?

But how good is it?

I think, it should work. But it also appears to be too shaky and too tenuous a connection to me—between the mainstream QM and my new approach.

Of course I’ve noted down a bit of maths to go with it too, and also the physical units for the quantities involved. Yet, two points remain:

As a relatively minor point: I haven’t had the energy to work out (let alone to do even the quick and dirty simulations for) all possible permutations and combinations of the kind of elements I am dealing with. So, there is a slim possibility that terms may cancel each other and so the formulation may not turn out to be general enough. (I’ve been fighting with such a thing for a long time by now.)

But as a relatively much more important point: As I said, this whole way of thinking about it seems too tenuous to me. Even if it works out OK (i.e., after considering all the permutations and combinations involved), this very way of looking at the things would still look at best tenuous to any one.

The only consolation I have is this idea (which had already become absolutely banal even decades ago):

Every thing about QM is different from the pre-quantum theories.

That’s the only thin thread of logic by which I my ideas hang. … Not as good as I wanted it. But not as bad as hanging all loose either…

And, yes, I’ve thought through the ontological aspects as well. … The QM ontology is radically different from the ontologies of all the pre-quantum theories. Especially, that of NM (Newtonian mechanics of particles and rigid bodies). But it is not so radically different from the ontology already required for EM (the Maxwell-Lorentz electrodynamics)—though there is a lot of difference between the EM and the QM ontologies.

And that’s what the current status looks like.

“So, when do you plan to publish it?”

Ummm… Not a good question. A better question, for me, is this:

What do I propose to do with my time, now?

The answer is simple. I will go in for what I know is going to be the most productive route.

Which is: I am going to continue loitering around.

Then, I will begin with taking detailed notes on the QM spin—the next topic from the mainstream QM—as soon as my mental energy returns.

That’s right. I won’t be even considering writing down my thoughts about that goddamn linear momentum operator. Not for any time in the near future. That’s the only way to optimize productivity. My productivity, that is.

So, sorry, I won’t be writing anything on the linear momentum any time soon, even if it precisely was the topic that kept me pre-occupied for such a long time—and also formed the topic of blogging for quite some over the recent past. So, sorry, this entire blog-post (the present one) is going to remain quite vague to you, for quite some time. You even might feel cheated at this point.

Well, but I do have a strong defence from my side: I’ve always said, time and once again, that I was always ready to share all my thoughts to “any” one. I mean, any one who (i) knows the theory of the mainstream QM (including its foundational issues), and (ii) also has looked into the experimental aspects of it (at least in the schematic form.)

So, any such a person can always drop a line to me.

Oh wait!

Don’t write anything to me right away. Hold on for a few days. I just want to kill my time around for now. That’s why.

I’ll let you know (may be via an update here), once I begin actually taking down my notes on the QM spin. That’s the time you—“you” the “any” one—may get in touch with me. That is, if “you” want to know what I’ve thought about that goddamn linear momentum operator. [OK. As the update at the top of the post indicates, now I’m ready.]

OK, bye for now, take care in the meanwhile, and don’t be surprised if I also visit your blog and all…

A Many songs I like:

[I also listened to a lot of songs over the past few days. I couldn’t find a single song that went very well with any one of my overall moods over the past few days… So, don’t try to read too much into this choice. And, I’ve got bored, so I won’t offer any further comment on this song either. (And, one way or the other, I actually don’t know why I like this song or the extent to which I actually like it. Not as of now, any way!)

(Hindi) जनम जनम का साथ है निभाने को (“janam janam kaa saath hai nibhaane ko”)
Music: Shankar-Jaikishan
Lyrics: Hasrat Jaipuri

I could not find a good quality original audio track. The “revival” version is here: [^]. It was this version which I first listened to, and used to listen to, while taking leisurely evening drives (for up to, say, 50 miles almost every day) in the area around Santa Rosa. Which was in California. But it didn’t feel that way. (It also was the home town of the “Peanuts” comics creator.) …

…OK, I will throw in one more:

(Marathi) तूं तेव्हा तशी (“too, tevhaa tashee”)
Music and Singer: Pt. Hridayanath Mangeshkar
Lyrics: Aaratee Prabhu

Which is yet another poem by Aaratee Prabhu, converted into a song by Hridayanath. But I won’t be able to talk about it. Not as of today anyway. Listening is good. A good quality audio is here [^].

…And, since I have been listening to songs a lot over the past few days, one more, just for this time around…

(Western, Pop) “How deep is your love”
Band: Bee Gees

I don’t know what the “Official Video” means, but it is here: [^]. I also don’t know what the “Deluxe Edition” of the audio means, but it’s here [^]. … I always happened to listen to the audio, which was, you know, at many places in Pune like in the H’ club (of the student-run mess at COEP hostels); at the movie theatres running English movies in Pune (like Rahul, the old West-End, and Alka); most all restaurants from the Pune Camp area (and also a few from the Deccan area); also in the IIT Madras hostels; etc. All of this was during the ’80s, only. I don’t know why, but seems like I never came across this song, even at any of these places, once it was ’90s. … As usual, I didn’t even know the words, and so, couldn’t have searched for it. A few days ago, I was just going through a compilation of songs of ’70s when I spotted this one, and then searched on its lyrics and credits and all. I had remembered—and actually known—only the music… But yes, now that I know them, the words too seem pretty good…

Anyway, enough is enough. I already wrote a lot!  High time to go back to doing nothing…

# Still if-ish…

1. Progress has slowed down:

Yep. … Rather, progress has been coming in the sputters.

I had never anticipated that translating my FDM code (for my new approach to QM) into a coherent set of theoretical statements is going to be so demanding or the progress so uneven. But that’s what has actually occurred.

To be able to focus better on the task at hand, I took this blog and my Twitter account off the ‘net from 26th February through 09th March.[* See the footnote below]

Yes, going off the ‘net did help.

Still, gone is that more of less smooth (or “linear”) flow of progress which I experienced in, say, mid-December 2020 through mid-January 2021 times or so, especially in January. Indeed, looking back at the past couple of weeks or so, I can say that a new pattern seems to have emerged. This pattern goes like this:

• On day 1, I get some good idea about how to capture / encapsulate / present something, or put it in a precise mathematical form. So, I get excited. (I even feel like coming back on the ‘net and saying something.)
• But right on day 2, I begin realizing that it doesn’t capture the truth in sufficient generality, i.e., that the insight is only partial. Or, may be, the idea even has loopholes in it, which come to the light only when I do a quick and dirty simulation about it.
• By the time it’s day 2-end, day 3 or at most day 4, I have become discouraged, and even begin thinking of postponing everything to a June-July 2021-based schedule.
• However, soon enough, I get some idea, hurriedly write it down…
• …But only for the whole cycle to repeat once again!

This kind of a cycle has repeated some 3–4 times within the past 15–20 days alone.

“Tiring” isn’t the right word. “Fatigue” is.

But there is no way out. I don’t have any one to even discuss anything (though I am ready, as always, from my side.)

And, it still isn’t mid-March yet. So, I keep going back to the “drawing board.” Somehow.

[* Footnote: Curiously though, both WordPress and RevolverMaps have reported hits to this blog right in this period—even when it was not available for public viewing! … What’s going on?]

2. Current status:

In a way, persistence does seem to have yielded something on the positive side, though it has not been good enough (and, any progress that did come, has been coming haltingly).

In particular, with persistence, I kept on finding certain loop-holes in my thinking (though not in the special cases which I have implemented in code). These are not major conceptual errors. But errors, they still are. Some of these can be traced back to the June-July times last year. Funny enough, as I flip through my thoughts (and at times through my journal pages), some bits of some ideas regarding how I could possibly get out of these loop-holes, seem to have occurred, in some seed form (or half-baked form), right back to those times. …

Anyway, the current status is that I think that I am nearing completing a correct description, for the new approach, for the linear momentum operator.

This is the most important operator, because in QM, you use this operator, together with the position operators, in order to derive the operators for so many other dynamical quantities, e.g. the total energy, the angular momentum, etc. (See Shankar’s treatment, which was reproduced in the postulates document here [^].)

The biggest source of trouble for the linear momentum operator has been in establishing a mathematically precise pathway (and not just a conceptual one) between my approach and the mainstream QM. What I mean to say is this:

I could have simply postulated an equation (which I used in my code), and presented it as simply coming out of the blue, and be done with it. It would work; many people in QM have followed precisely this path. But I didn’t want to do that.

I also wanted to see if I can make the connections between my new approach and the MSQM as easy to grasp as possible (i.e., for an expert of MSQM). Making people understand wasn’t the only motive, however. I also wanted to anticipate as many objections as I could—apart from spotting errors, that is. Another thing: Given my convictions, I also have to make sure that whatever I propose, there has to be a consistent ontological “picture” which goes with it. I don’t theorize with ontology as an after-thought.

But troubles kept coming up right in the first consideration—in clearly spelling out the precise differences of the basic ideas between my approach and the MSQM.

And yes, MSQM does have a way of suddenly throwing up issues that are quite tricky to handle.

Just for this topic of linear momentum, check out, for instance, this thread at the Physics StackExchange [^] (especially, Dr. Luboš Motl’s answer), and this thread [^] (especially, Dr. Arnold Neumaier’s answer). The more advanced parts of both these threads are, frankly, beyond my capacity. Currently, I only aim for that level of rigour which is at, say, exactly and precisely the first three sentences from Motl’s answer!…

…We the engineers can happily ignore any unpleasant effects that might occur at the singular and boundary points. We simply try and see if we can get away ejecting such isolated domain points from any theoretical consideration! If something workable can still be obtained even after removing such points out of consideration, we go for it. So, that’s the first thing we check. Usually, it turns out we can isolate them out, and so we proceed to do precisely that! And that is precisely the level at which I am operating…

Even then, issues are tricky. And, at least IMO, a good part of the blame must lie with the confusions wrought by the Instrumentalist’s dogma.

… What the hell, if $\Psi(x,t)$ isn’t an observable itself, then why does it find a place in their theory (even if only indirectly, as in Heisenberg’s formulation)? … Why can’t I just talk of a property that exists at each infinitesimal CV (control volume) $\text{d}x$? why must I instead take something of interest, then throw in the middle an operator (say a suitable Dirac’s delta), and then bury it all behind an integral sign? why can’t those guys (I mean the mathematical terms) break the cage of the integral sign, and come out in the open, just to feel some neat fresh air?

… Little wonder these MSQM folks live with an in-principle oscillatory universe. It’s a weird universe they have.

In their universe, Schrodinger’s cat is initially in a superposition of being alive and dead. But that’s not actually the most surprising part. Schrodinger’s cat then momentarily (or for a long but finite time) becomes full dead; but then, immediately, it “returns” from that state (of being actually dead) to once again be in a superposition of dead + alive; it spends some time in that superposition; it then momentarily (or for a long but finite time) becomes fully alive too; but only to return back into that surreal superposition…

And it is this whole cycle which goes on repeating ad infinitum.

… No one tells you. But that’s precisely what the framework of MS QM actually predicts.

MSQM doesn’t predict that once a cat does somehow become dead, it remains dead forever. And that’s because, in the MSQM, the only available mathematical machinery (which has any explanation for the quantum phenomena), in principle, predicts only infinite cycles of superposition–life–superposition–death–superposition–….

The postulates of the MS QM necessarily lead to a forever oscillatory universe! Little wonder they can’t solve the measurement problem!

One consequence of such a state of the MS QM theory is that thinking through any aspect becomes that much harder. It isn’t impossible. But hard, yes, it certainly is, where hard means: “tricky”.

Anyway, since the day before yesterday, it has begun looking like this topic (of linear momentum operator), and to the depth I mentioned above, might get over in a few days’ time. At least, that day 1–day 2–etc. pattern seems to have broken—at least for now!

If things go right at least this time round, then I might be able to finish the linear momentum operator by, say, 15th of March. Or 18th. Or 20th.

Addendum especially for Indians reading this post: No, the oscillatory universe of the MSQM people is not your usual birth-life-death-rebirth cycle as mentioned in the ancient Indian literature. The MSQM kind of “oscillations” aren’t about reincarnations of the same soul but in different bodies. In MSQM, the cat “return”s from being dead with exactly the same physical body. So, it’s not a soul temporarily acquiring one body for a brief while, and then discarding it upon its degeneration, only to get another body eventually (due to “karma” or whatever).

So, the main point is: In MSQM, Schrodinger’s cat not just manages to keep the same body, the physical laws mandate that it be exactly the same body (the same material) too! … And, the MS QM doesn’t talk of a soul anyway; it concerns itself purely with the physical aspects—which is a good thing if you ask me. (Just check the postulates document, and pick up a text book to see their typical implications.)

3. Other major tasks to be done (after the linear momentum operator):

• Write down a brief but sufficiently accurate description of the measurement process following my new approach. This is the easiest task among all the remaining ones, because much of such a description can only be qualitative.
• Translate my ideas for the orbital angular momentum into precise mathematical terms—something to be done, but here I guess that with almost all possible troubles having already shown up right in the linear momentum stage, the angular momentum should proceed relatively smoothly (though it too is going take quite some time).
• And then, the biggest remaining task. Actually, many sub-tasks:
• Study and take notes on the QM spin.
• Think through and integrate my new approach to it.
• Write down as much using quantitative terms as possible.

At this stage, I don’t know how long it’s going to take. However, for now, I’ve decided on the following plan for now…

4. Plan for now:

If there remain some issues with the linear momentum operator (actually, in respect of its multi-faceted usages in the MSQM, and in explaining these from the PoV of my approach including ontology), and if these still remain not satisfactorily resolved even by 15th or 18th of March (roughly, one week from now), then I will take a temporary (but long) break from QM, and instead turn my attention to Data Science.

However, if my description for $\hat{p}()$ (i.e. the linear momentum operator) does go through smoothly during the next week, then I will immediately proceed with the remaining QM-related tasks too (i.e., only those which are listed above).

5. Bottom-line:

Expect a blog post in a week’s time or so, concerning an update with respect to the linear momentum operator and all. (I will try to keep this blog open for the upcoming week, but I guess my Twitter account is best kept closed for now—I just don’t have the time to keep posting updates there.)

In the meanwhile, take care and bye for now.

A song I like:

(Marathi) ती येते आणिक जाते (“tee yete aaNik jaate…”)
Lyrics: Aaratee Prabhu
Music: Pt. Hridaynath Mangeshkar
Singer: Mahendra Kapoor

[ Mahendra Kapoor has sung this song very well (even if he wasn’t a native Marathi speaker). Hridaynath Mangeshkar’s music, as usual, pays real good attention to words, even as also managing to impart an ingenious melodic quality to the tune—something that’s very rare for pop music in any language.

But still, frankly, this song is almost as nothing if you don’t get the lyrics of it.

And, to get the lyrics here, it’s not enough to know Marathi (the language) alone. You also have to “get” what precisely the poet must have meant when he used some word; for instance, the word “ती” (“she”). [Hint: Well, the hint has already been given. …Notice, I said “what”, and not “who”, in the preceding sentence!]

But yes, once you begin to get the subtle shades of the poetry here, then you can also begin to appreciate Hridaynath’s composition even better—you begin to see the more subtle musical phrases, the twists and turns and twirls in the tune which you had missed earlier. So, there’s a kind of a virtuous feedback circle going on here, between poetry and music… And yes, you also appreciate Mahendra Kapoor’s singing better as you go through the circle.

This song originally appeared as a part of a compilation of Aaratee Prabhu’s poems. If I mistake not (speaking purely from memory, and from a distance of several decades), the book in question was जोगवा (“jogawaa”). I had bought a copy of it during my UG days at COEP, out of my pocket-money.

We in fact had used another poem from this book as a part of our dramatics for the Firodiya Karandak. It was included on my insistence; I was a co-author of the script. As to the competition, we did win the first prize, but not so much because of the script. We won mainly because our singing and music team had such a fantastic, outstanding, class to them. Several of them later on went on to make full-time career in music…. The main judge was the late music composer Anand Modak, who later on went to win National awards too, but back then, he was at a fledgling stage of his career. But yes, talking of the script itself, in the informal chat after the prize announcement ceremony, he did mention, unprompted and on his own, that our script was good too! (Yaaaay!!) …Back then, there was no separate prize for the best script, but if there were to be one, then we would’ve probably won it. During that informal chat, the judges hadn’t bothered to even passingly mention any script by any other team!)

…Coming back to the book of poetry (Aaratee Prabhu’s), I think I still have my copy lying somewhere deep in one of the boxes, though by now, due to too many moves and all (I had also taken it to USA the first time I went there), its cover already had got dislodged from the book itself. Then, a couple of weeks ago, I saw only the title page peeping out of some bunch of unrelated and loose papers, and so, looks like, the book by now has reached a more advanced stage of disrepair! … Doesn’t matter; no one else is going to read it anyway!

A good quality audio is here [^].
