My latest paper.﻿
Abstract: We study a one-parameter family ($\ell=1,2,3,\ldots$) of configurations that are square-ice analogues of plane partitions. Using an algorithm due to Bratley and McKay, we carry out exact enumerations in order to study their asymptotic behaviour and establish, via Monte Carlo ...

The following notes are a transcription and a translation into English of lecture notes (192 pages!) of de Bruijn's course on combinatorics, originally given in the 70s and 80s:

http://goo.gl/ZXO5AV

you may be surprised where they are hosted. From the introduction:

Combinatorics is mainly about counting. The nice thing about counting is that you learn something about the thing that you are counting. While counting, you notice that your knowledge about the subject is not sufficiently precise, and so counting becomes an educational activity. When two sets have the same number of elements, you try to understand why that is the case by establishing some natural bijection between the two.
N. G. de Bruijn recalls that sometime around 1975, he counted the number of a certain type of logics with three variables. There were a lot of them; some number with 14 digits. A little while later he saw an article that was about something completely different, but it concluded that the number of those objects was exactly that same number with 14 digits. He got curious and read the article very carefully. Indeed, if you thought deeply about it you could see that you could interpret those objects also as logics.

Meet Ravi Jagadeesan, an American of Indian origin. He is a gold medalist at the International Mathematical Olympiad in 2012 and is currently a student at Harvard. He just put a paper on the math arXiv: http://arxiv.org/abs/1601.05070﻿

Thanks Gautam da. Things are going fine.   Thanks. It was a very smooth run even though I missed out on going under 2h.﻿

John Bardeen, the leading condensed matter theorist of his day, was quite wrong when he dismissed a startling prediction by the unknown Brian Josephson.

The detection of gravitational waves:

The gravitational chirp that was heard! Bird watchers can identify birds from their chirps and the bottom two figures show that scientists can do that for gravitational chirps.﻿

There is going to be an announcement on Feb 11 (http://www.ligo.org/news/media-advisory.php) on the direct detection of gravitational waves by LIGO. Rumour has it that they have seen the merger of two large black holes into one large black hole plus a huge amount of energy released via gravitational waves. Indirect evidence for gravitational waves was first shown by Hulse and Taylor in 1974 for which they received the Nobel prize in 1993 (http://www.nobelprize.org/nobel_prizes/physics/laureates/1993/). This is big news and opens the door into a an era of "gravitational telescopes".  ﻿
LIGO Scientific Collaboration (LSC) seeks to detect gravitational waves and use them for exploration of fundamentals of science.

It is official. Gravitational Waves have been detected. http://www.aps.org/publications/apsnews/updates/gwaves.cfm﻿

This year I have added a new twist to my annual run at The Wipro Chennai Marathon . I am running to raise money for Vidya Sagar. The precise amount that you wish to donate is not relevant. I just would like a lot of people to donate. Click on this link and you will be directed to a page where you can donate.﻿
The Spastics Society of India was born in March 1985 in a garage in Chennai. It was started by Mrs. Poonam Natarajan, the mother of a child with profound disability, since there were no services available for this group. It was renamed ‘Vidya Sagar’ in 1998. Today Vidya Sagar is housed in a building that is designed in a manner that is totally barrier-free, and accessible to persons with disabilities, on land leased by the Government of Tamil ...

Try to donate without PAN card number. It is just means you don't get the IT deduction, I think. Let me know if it works.﻿

(Infinite dimensional) Linear Algebra for the mathematically oriented physicist. I have been on the lookout for a book that has a nice introduction to Hilbert spaces -- chapter one does that. ﻿
