Happy Witten’s Day!

My calendar says it is Witten’s birthday today. Hence this post’s title.

Many people have heard of Schrödinger’s cat but how many people have heard of Witten’s dog?

Thought Experiment

Most people follow Newton’s laws of motion but how many can truly say they understand the Newton-Witten equation?

Most people have no idea where this is going but then neither do I. Though, I do hope he does not remember the day almost a decade ago when I was able to “offend” him in a short walk to Stony Brook train station by suggesting he should have done something else or gone to some other place or some such thing. I also do not want to remember such “offensive” things for obvious reasons. However, I do remember that I was going for a haircut on that day and today I realize I need, very urgently, another haircut. But then it is raining heavily today and tomorrow is another day of lockdown here. So better to postpone this trip to the barber shop till next month.

With this existential crisis out of the way, let me read one of his papers today on the occasion of Witten’s Day. (I guess that is how one celebrates (t)his day!) Hmm… interesting! Let’s make it two as I choose the following papers (taking up less than 20 pages):

2004.14192 & 2005.12336

Post-20 World…

What would the post 2020 world look like? One might wonder at this point in time… But who knows? I mean, who really knows? Really, who at all?

Status?

Anyway, that’s not what the title of this post refers to. It refers to the fact that I crossed the 20 papers mark this month, last month, this year depending on how you count. But let’s keep it simple and count the entries on InspireHEP (20), subtract my thesis (-1) and add two papers from IITKGP that are not there (2) so we get a total of 21. And that’s definitely crossing the just-made-up-number-for-this-post of 20 last month.

Now one may be wondering: Am I proud of this “achievement”? Not really, but I am “proud” of the last few papers I’ve written. That sentence may sound like I’m suggesting am not proud of some papers written before those. Precisely, that’s what it rightly suggests as I’m indeed not proud of a couple of those papers. But that’s a story for another day, when I don’t have much better things to do than to reminisce about things that didn’t exceed my expectations.

Of course, no scientific activity is done in vacuum (in a metaphorical sense, I guess), it is a result of collaboration, knowingly or unknowingly. And talking of collaborations, I seem to have had only two long-time collaborators: Warren Siegel and Marcos Crichigno. Former for obvious reason and latter also for obvious reasons. On last count, I have 6 papers with both (no overlap). With every other collaborator (of whom there are many, which surprises me!) I have only a single paper (tons of overlap). That may change in near future but I like the numerology as of now.

Another interesting fact, one of my last year’s paper’s list of authors abbreviates to AB²J²M! For the unfamiliar ones, ABJM is another well-known (to those who know-it-well) abbreviation for authors of this paper: O. Aharony, O. Bergman, D. L. Jafferis, J. Maldacena. The ABJM theory is like a harmonic oscillator for 3d supersymmetric theories, just like N=4 super Yang-Mills is for 4d ones.

Talking about my papers, how can I not talk about my parody papers from yesteryears? These are the two: 2010 and 2014. You might find that the latter has some overlap with my newest paper, which is purely coincidental. (Ya, right!) I guess I’ll leave it at that for now with the interesting facts about my publication record.

Oh, you might have noticed that my site has got a new coat of paint. That’s because Google is transitioning people from the old Sites to new Sites so I had to do the transformation sooner or later. I think it looks all right and it displays nicely on all sorts of devices. But gone are the days when one could edit the HTML code directly. That’s why the font colour is just black and blue on the pages on this new site!

To finish this post, I will leave you with one Sher from the last Ghazal of Rahat Indori who passed away on 11 August:

वबा ने काश हमें भी बुला लिया होता
तो हम पे मौत का एहसान भी नहीं होता

Waba ne kaash hamein bhi bula liya hota
To ham pe maut ka ehsaan bhi nahin hota

How I wish the epidemic had claimed me
Death would not have then indebted me

राहत इंदौरी (Rahat Indori)

End of A Legend

The one who knew he was a great Shayar who would recite great Shers once in a while (preceded by a warning)…

ये चंद लोग जो बस्ती में सबसे अच्छे हैं
इन्ही का हाथ है मुझको बुरा बनाने में

Ye chand log jo basti mein sabse achhe hain
Inhi ka haath hai mujhko bura banane mein

These few good people in village
Are the reason I turned out bad

– राहत इंदौरी (Rahat Indori)

…is no more.

The one who stood up to the Sun…

पसीने बांटता फिरता है हर तरफ सूरज
कभी जो हाथ लगा तो निचोड़ दूंगा उसे

Paseene baanTta phirta hai har taraf sooraj
Kabhi jo haath laga to nichod dunga use

The Sun keeps dispensing sweat all over the world
If I ever get my hands on it, I’ll surely wring it dry

…will be surely missed.

I have translated a few more Shers of his in a couple of posts in the past: here and here (the two above are copied from the latter). Let me do one new translation (as always, read the page titled "Shayari" on this blog if you haven't read it already) in his honor, where he points out the irony in being a consumer and a product:

खड़े हैं मुझको खरीददार देखने के लिए
मैं घर से निकला था बाज़ार देखने के लिए

Khade hain mujhko khariddaar dekhne ke liye
Main ghar se nikla tha bazaar dekhne ke liye

Standing out there for me are buyers surveying
I had went out of my house for market surveying

Let us end this post with one of the last of his recitals from earlier this year.

We Are at Crossroads…

…and we look back at old times.

Snow Times

I was recently suggested this video from Rekhta channel by YouTube and it jogged my memory from way past. It led me to one of my Superpartner’s old posts where we had translated single Shers of various poets. One of those poets was Naseer Turabi, whose well-known Ghazal was the subject of that recently suggested video. I also own a rendition of this Ghazal by Abida Parveen. Anyway, today I thought about translating the whole ghazal. Why now? Because now I know the meanings of all the words, thanks to Rekhta. 😊 So here goes the translation (as usual, do read my disclaimer in the “Shayari” tab):

वो हम-सफ़र था मगर उस से हम-नवाई न थी
कि धूप छाँव का आलम रहा जुदाई न थी

Wo ham-safar tha magar us se ham-nawaai na thi
Ki dhoop chaanv ka aalam raha judaai na thi

–E was a companion but compatibility was never claimed
Like a scene with sunlight and shade they never separated

न अपना रंज न औरों का दुख न तेरा मलाल
शब-ए-फ़िराक़ कभी हम ने यूँ गँवाई न थी

Na apna ranj na auron ka dukh na tera malaal
Shab-e-firaaq kabhi ham ne yun ganwaai na thi

Not my grief, not their sorrows, not your regret
Like so the night of separation I had never wasted

मोहब्बतों का सफ़र इस तरह भी गुज़रा था
शिकस्ता-दिल थे मुसाफ़िर शिकस्ता-पाई न थी

Mohabbaton ka safar is tarah bhi guzra tha
Shikasta-dil the musafir shikasta-paai na thi

The journey of love was even traversed like this
The travellers’ hearts ached but feet never ached

अदावतें थीं, तग़ाफ़ुल था, रंजिशें थीं बहुत
बिछड़ने वाले में सब कुछ था, बेवफ़ाई न थी

Adaawatein thin, taghaaful tha, ranjishein thin bahut
Bichhadne waale mein sab kuch tha, bewafaai na thi

There was hatred, there was neglect, and lots of ill-will
The separated one felt them all, but was never corrupted

बिछड़ते वक़्त उन आँखों में थी हमारी ग़ज़ल
ग़ज़ल भी वो जो किसी को अभी सुनाई न थी

Bichhadte waqt un aankhon mein thi hamari ghazal
Ghazal bhi wo jo kisi ko abhi sunaai na thi

While parting those eyes had my Ghazal in them
That too the Ghazal which had been never recited

किसे पुकार रहा था वो डूबता हुआ दिन
सदा तो आई थी लेकिन कोई दुहाई न थी

Kise pukaar raha tha wo doobta hua din
Sada to aai thi lekin koi duhaai na thi

Who was being called by the fleeting dusk
There did come a voice but it never pleaded

कभी ये हाल कि दोनों में यक-दिली थी बहुत
कभी ये मरहला जैसे कि आश्र्नाई न थी

Kabhi ye haal ki donon mein yak-dili thi bahut
Kabhi ye marhala jaise ki aashnaai na thi

Sometimes it was as if both of them were in accord
Sometimes the state of having been never befriended

अजीब होती है राह-ए-सुख़न भी देख ‘नसीर’
वहाँ भी आ गए आख़िर, जहाँ रसाई न थी

Ajeeb hoti hai raah-e-sukhan bhi dekh ‘Naseer’
Wahan bhi aa gaye aakhir, jahaan rasaai na thi

The path-of-poetry is quite weird, notice ‘Naseer’
Even arrived there, where a path was never paved

– नसीर तुराबी (Naseer Turabi)

Listen to this ghazal being recited by the poet himself.

Life in These Times

I have made so many records during this lockdown and I’m breaking them as I write this post. For example, I haven’t stepped out of my house from the 21st of March, 2020. It is the 65th day of the record today and tomorrow, I will break it by making it 66. Even after a C-sec delivery, I tried breaking down the hold of orthodox thoughts (prevalent in my families) and went out to watch a movie before Sakura had turned a month old. Sometimes all this staying indoors for so long seems like one long dream and no one seems capable of waking me up. I have broken records of sleeping only for 5 hours, and sleeping for 5 hours on consecutive days, and so on. I have more respect for people who permanently work from home and manage kids and home all too well. Have realized that’s not my cup of tea and it definitely inhibits my thinking, productivity, creativity, etc.

People seem to have had a big realization during this lockdown: they have figured out the right/perfect/new ways to live. I did try to introspect many a times but didn’t reach anywhere. Just like my swimming classes which went too poorly, the only thing that I have been able to do is to kick and float through this lockdown. Some people have worked enormously during these times – the delivery people, the medical/paramedical staff, all the support departments operating on the ground and also those that have supported us online.

On the 9th of April, we had placed an order on Swiggy and on the 10th of April, we were surprised to read the following snippet of an article about “lockdown heroes” in ‘The Telegraph’:

The Telegraph: Lockdown Heroes

It brought smiles to our faces because (as you may have guessed) he was the one who had delivered those sweets to us the previous day and was featured in a newspaper but we were also saddened by the fact that we were his only customers that day. This reminded me of my Mother’s words who used to say (to impart some financial understanding to us) – “Most of the people work too hard for too little in this country”.

Here’s a fun little video and as Sandi Toksvig says ‘Be Kind’.

Sketchbook Ends.

After going through all the nine stages of disbelief, I have finally accepted that Sketchbook had ended. Seriously and utterly accepted that fact. So this is the final mention of Sketchbook v14 on this blog. The previous one is here. But this is the final one. Totally last one where I share some pages from the second half of the volume and my guesses at what they’re all about.

Sketchbook v14 p92-93

Juju, Nagisa and Sora are discussing the crawling curve of a caterpillar and comparing it with the Greek letter Ω. Also it seems that’s how a futon should look when used properly!

Sketchbook v14 p98-99

Sora and Ao in the kitchen with their food related antics. At least, Sora seems to be enjoying them.

Sketchbook v14 p110-111

Asaka is trying to showcase usage of a gourd that she made… As a container for a genie?

Sketchbook v14 p122-123

Just for the Hazuki’s serene pose and obviously, also for how a lint roller should not be used!

Sketchbook v14 p132-133

What little scenes of everyday life. Sheer brilliance! I’ll miss these in my everyday life. Also, this is from the last comic-strip-style chapter of Sketchbook. It is followed by 3 normal-manga-style chapters. The “first” page of the first such chapter.

Sketchbook v14 p140-141

Finally, Kei and Takane seem to have decided to join the Art Club, officially. This chapter then goes on to welcome them with a party where everyone tries to cook something or the other in the club room… I guess.

Sketchbook v14 p154-155

This chapter ends with Sora sketching “everyone” as the party ends with the usual approval from Ooba-senpai. The second regular-comic-style chapter is of course about the Cats. And I will leave the third chapter a mystery.

Well, that’s all. No mention of Sketchbook from now on here. Yes, not at all.

Apart from the pending

Work from Home…

In these depressing times, as we all work from home, humanity and sanity slowly slips away through our soapy hands.

In these tough times, as we don’t know what to prioritize, developers loose their valuable users/customers. I don’t know how true that last sentence is but I have definitely lost the one and only user (my superpartner) of my MATLAB program ‘AcBook’. But that doesn’t stop me from releasing its next update (officially at the end of this month but the installer has been already available for quite some time now).

In this release, I have mostly focussed on replacing the old exchange rates provider by a new one. Because the older one got a bit greedy and reduced the number of data requests one could make from 1000/month to 200/month in the basic free plan! Not that I was using the full quota. Even on a busy month, I don’t think I made more than 100 requests so 200 was more than enough given that nobody else is using the program now. But what really bugged me was that the rates were now updated daily instead of hourly! So if another provider could still support 1000 requests per month for free and the data was updated hourly, then why would I not transition to it. That’s exactly what I thought and did. In the transition process, I also learned that MATLAB can handle JSON formatted web replies quite well. That has made the startup time of the program a bit shorter and less error-prone as fewer file read/write operations are needed now. Also, made the ExChanger future-proof in case some currencies are added or removed by the new provider. Overall, I’m quite proud of the achievement and to give credit where credit is due, here’s a screenshot of the program’s login screen:

AcBook v7.8

Life – T&C Apply…

What happens when one doesn’t write a post for a year or so? Out of the many things one forgets is the name of the app they have been using to compose posts. It took me 30 secs to remember what is ‘Windows live writer’ called today (It’s called ‘Open live writer’) as I went on to write a bunch of posts in the end of December to fill up the year’s quota of posts on the blog. I had taken my annual break of 2 weeks, gladly in the month of December and you would ask why? ‘Because I have my leaves accumulated’ is one of the answers but the obvious reason that everyone might guess is to spend time with the family. In my case, it was more specific than that – to spend time with myself. Out of the many things people say, one of the things they say right is that you never get that straight 8 hours of sleep once you become a parent. Over the course of the year, I have bought books which I have felt so keen about to read but either have not been able to start them or have left them incomplete. I had wished to spend the break time primarily doing that and have been able to read 5 books, not as many as I thought I would but happy to have a number greater than 0. I wanted to do more – like drive a car or join a Zumba class but where is the time.

Every person in this country who has a bank account knows about SBI and this year, SBI promoted its new online website named Yono. It was advertised using emails, newspaper ads, hoardings, etc. making sure everyone who used Internet banking went on to try Yono at least once. The first time I tried testing, I found something like the following while trying to fill in occupation:

Part of Card Application Form

We haven’t got to ‘E’ in this screenshot and that was the end of Yono for me. If anyone has created a longer drop-down list than this one ever in their life, please let me know in the comment section below.

I have lost a good number of senior family members in 2019. With each death, I have realized that life is not just short, it is too short, and it doesn’t matter if I live to the age of 94 (like my Grandmama who died this year) or to a mere 46 (like my Mother who died in 2010). Whatever that number be, life is very short indeed and it would be a total waste of my time if I do redundant things that don’t matter in the end, that don’t contribute to my prime goal at the end. My mother lived for a few years but wrote 27 journals to her credit. She wrote very fast because she had the capability of writing down things as people spoke. Sometimes I wonder if she knew what was coming along. Being with my mother taught me love, her leaving has taught me life. In general, the deaths have taught me to focus on important things, be mindful of the days that are not going to come back and do things that make me truly happy without bothering or causing trouble to anyone else and if there is a paradise, I wish I can be granted a place there and I so wish to meet some of the loved ones there, whom I have lost here, one time again, this one which would be forever.

On that note, I wish you & your family/friends a Great (replace ‘Great’ with any/all adjectives you like) 2020 – the start to another decade and hopefully one with a better climate, a bit more peaceful & safe and one which can make the world a better place to live for future generations to come.

Trip to the UK

This year, I travelled to UK in September for about a month and before the year ends, I would like to share my memories from the trip. I would like to start with the best part first. I travelled with my father and daughter. My father has been to China before this. When asked to describe the China trip in a few words, he said ‘Though the country like us has a lot of people, it doesn’t feel so in the public places. People are cleaning there all the time. They have a simple technique to pick up cigarette butts. The metro is just wonderful, but I so wish if the people there could speak some English’. About UK he said ‘the GPS is extremely useful, and I could read the directions very well for the first time on phone. There are pigeons and ducks everywhere. Everything though is of higher quality but very expensive. People are jogging/running all the time which explains the fewer Pharmacies. Our Railways follow the same system as theirs, it’s just that theirs looks cleaner’. It was the first trip outside India for my daughter. I have no idea how she would describe it. Maybe she can say something in future when she looks at the pictures. From what I could observe, she loved the green grass in parks with fewer children to share it with. She ran, slept and rolled over the grass, while she keeps on the lookout for insects here.

Green grass

We did some touristy things like visiting the London eye, Madame Tussauds, Buckingham Palace, Westminster Abbey, a lot of Parks like the James’s Park/Regents Park/Kensington Gardens/Greenwich Park and even visited farms for my daughter like Mudchute, and museums like the National Maritime Museum. It was quite a feeling to stand on the Meridian line and observe the home of Greenwich Mean Time at the National Maritime Museum. Sakura had the experience of traveling on a Buggy for a month. The first time she saw us preparing the Buggy for travel she cried but once she realized how comfortable it was to ride on, she used to just go and sit on the Buggy asking me to take her out on a walk. The weather was chilly, but the air was clean and none of us had to take any anti-allergens or medicines for cold.

I used to visit the nearby Supermarkets, Tesco mostly, to buy everyday stuff. On most of the days, Sakura sat on the Buggy while I picked up items and paid at the counter but one day she wanted to come out and check the aisles herself. Without me forecasting what she could do, I pulled her out of the buggy and there she was, wandering around me. While I moved to different aisles, she stuck to the one with chocolates and I didn’t mind her doing that till she was just being observant. It must have been a few minutes when I heard one of the shopkeepers asking me to check what my baby was up to. She had thrown a lot of chocolates on the floor and the moment she saw me, she started shouting, anticipating a not so pleasant conversation between her and me. Well… that was one embarrassing situation. I disliked myself for having taken her out of the Buggy in a Supermarket.

At a local park in London

We got 4 complete weekends, one of which we spent by traveling to a town named York. My father found a driver from Kerala, South India to speak to. In a 20 min Uber ride, the driver narrated his life in brief. That’s how simple I wish to keep my life too, one which can be explained in a few sentences, its goals and objectives clearly stated. He told my father that he loved his life in York as a driver. His wife who was a nurse had brought him to York. He has 2 lovely children and York has some of the finest schools in UK, something that he is very happy of. My father asked how life of a medical practitioner in UK was, to which he said “It’s tiring. The work hours are long, and doctors/nurses often work overtime because there is just so much to be done and written down.” My father was glad that the doctors are at least not beaten up like in our country. There are nearly 150 Indian families in a small town like York in UK and nearly 40 from just one South Indian state. One of the serious questions my father asked him was if he missed his home country to which he said ‘Not at all. The country and town have given him so much that he considers coming to York one of the best decisions of his life’.

We walked almost the whole town of York, covering the York city wall, York Minster, York’s chocolate story, York Shambles including the Wizardry shops, bakeries, open market, etc. We also met an elderly man who came forward on his own to take pictures for us as a family. Maybe he saw how I sulked at taking selfies/groupfies. People were extremely friendly; it seemed they had time to talk to strangers. It was quite nice to see a lot of elderly couple coming out and having breakfast together, chatting/talking to each other instead of using mobile phones. Street life seemed like a part of their life because by the time it was lunch hour, the streets were full of locals.

The highlight of my whole trip was catching a glimpse of Mr. Tom Branson (Real name: Allen Leech) from Downton Abbey. I saw him at the York Railway station on our return trip back to London and I think my eyes were wide open, but he happened to smile. I was so shocked to see him that I forgot to notice who was walking next to him, but I did notice that he smiled at his neighbor too as he walked along, almost saying something non-verbally in his smile.

In swing motion

The month flew by and all I’m left with now are memories, mostly beautiful and some funny ones. Now, if you wish to catch a few glimpses of my trip through my lens, please look at an album here.
