Feeble February

The weather has been all over the place this month. Mornings and Evenings are quite chilly but the rest of the day is quite warm. I seem to turn on the fan for 10 minutes every hour or so. There were again a few weddings this month but I didn’t attend any as I did in November because Sakura had a few Olympiad exams this month and her final exams for class 3 start next week. You may wonder why I did not go alone as I did in November! Well, I wanted to help her “revise” regularly this time. Anyway, it seems she did as good/bad as last time so my “help” may not have helped that much. Or, maybe it “helped” to maintain that level of consistency!๐Ÿ˜† We did take a weekend trip to Kochi before the exams, so there’s that too. And remember Fort Kochi is not a Fort!๐Ÿคฏ

I have also been programming the past few couple of weeks and the result of that is here. The actual code and stuff is accessible directly on GitHub. It is basically a card game that became well-known as a nontrivial programming problem in a contest organized by MathWorks last year.

Clueless

Out of the blue, 5 chapters of Sketchbook dropped this year after a gap of nearly 3 years! And these did not disappoint. Two sample strips about cooking food are perfect:

Lastly, I listened to a “new” poet this month. I was amazed at his choice of simple words which packed a brilliant punch to where it mattered! This is again one of those untranslatable Ghazals so I won’t even transcribe it in English. But I will try to explain it below, though I don’t think I will do it justice.

The whole Ghazal is about dilemmas in various situations, where one has to choose one option or the other. This Ghazal is so structured that the first and last Sher themselves open up dilemmas in similar situations but with contradictory options! That’s what makes this a great Ghazal. So the first Sher asks in its first line whether to change one’s path or one’s company (caravan); only to wonder in the second line if it’s better to change the leader. The second Sher complains to the doctor that the pain does not subside; and wonders whether to change the disease or the medicines. The third one is upset about fighting with oneself; and wonders whether to change oneself or the mirror! The fourth one is so profound as to notice that no prayer is being answered; and wonders whether to change the words or the gods! The last Sher contains quite a few technical terms related to Ghazals (refer to this post for their technical meanings) but they all have “normal” meanings too, so in essence, this Sher is full of เคถ्เคฒेเคท เค…เคฒंเค•ाเคฐ (Puns) raising it to the highest level of poetical beauty I’ve ever witnessed! Here is what I think are its dual meanings: 1. My life’s refrain (เคฐเคฆीเฅž) is “upset”. Should I change the meter (เคฌเคนเคฐ) or the “rhyme” (เฅ˜ाเฅžिเคฏा)? 2. My life’s co-travellers (เคฐเคฆीเฅž) are upset. Should I change my ways (เคฌเคนเคฐ) or the followers (เฅ˜ाเฅžिเคฏा)? What a reversal of viewpoint compared to the first Sher: there, the leader seemed to be the problem and here, the followers! To appreciate the beauty of this Ghazal fully, here is Dixit Dankauri reciting it in full (starts around half-time):

His previous recitals are also worth listening to: 2019, 2021 & 2023. One more on the occasion of

Happy New Semester!

Spring Semester of this year 2010 starts tomorrow here at Stony Brook. I am registered for Advanced QFT (once more!) and the usual seminar courses! That’s enough about Physics on this blog!

Now, spacetime for some of the tidbits I’ve been thinking about in the past few weeks for this post:

Some oxymorons from Sketchbook:

It is sad that no one is going to appreciate the above compilation! Anyway, this is enough writing for today for almost no (⇒0) readers out there! So finally,

Caravan has passed!

Fail to Pass, Hate to Love & Dying to Live

Such oxymorons make one think what do words mean after all???

As Gopaldas 'Neeraj' says "เคถเคฌ्เคฆ เคคो เค•ेเคตเคฒ เค›เคฒ เคนै..." (Words are just illusions...) So true... words often hide or reveal too much... relevant or irrelevant information!!!

Gopaldas 'Neeraj' @ IIT Roorkee

Now you would be wondering why am I being philosophical and starting a blog with such 'debatable facts'! Well, because they say the beginning of any article should be catchy and what is better than a controversy or quotes (shayaris if you prefer) from a Great Poet!!!

Anyway lets get to our usual stuff, i.e. Physics and stuff related to it. Just to make an explicit connection with the few lines above, lets consider a statement: "Lifetime of the Muon is 2.2 ฮผsec". Now is this statement really that simple and conveys all relevant info? No. The words have hidden a lot of info and hard-work that goes into arriving at that seemingly simple statement. In addition, the word 'Lifetime' as used here has a specific meaning which is implied but not at all obvious to someone who is not conversant with the terminology!

Have a look at this file that gives a precise meaning for the word 'Lifetime' and some details on the experimental aspect (ฮผ source, detector, electronics, analysis/simulation software, etc.) to get an idea of what all you 'missed' in the above statement. Much more than that, you will notice that there is a formula for ฮผ lifetime (on page 10) containing various constants and its mass. Experimental determination of some quantity is all right but how do you get a formula for it in terms of a finite number of basic constants?

This is going to be done below i.e. what follows is a 'derivation' of that formula (in the framework of QFT). Those who are unsure of whether to continue or not, should probably stop as this blog post got over somewhere around the 3rd paragraph! [ I started this post just to put this derivation here! Muhahahaha :)) As some of you may have guessed, this was indeed an assignment problem in GS's QFT-II course!]

Prelims.

Evaluating M^2...

Within M^2...

M^2 Evaluated.

Decay Rate...

Total Decay Rate...

Calculation finally over.

Number at last!

Now, you 'know' how the lifetime of Muon is calculated theoretically and the amazing fact remains that it matches very well with experiments! In summary, I can say that I have managed to pass through it all, have come around to love it and am definitely living to die not the other way around!

All-in-one!
