- A clue to my email address: it is necessary and sufficient to
know that I get email on this machine
- Almost every morning I spend some time trying to solve a Sudoku puzzle
from a newspaper. Apart from this direct interest in solving these puzzles,
the mathematics of Sudoku also fascinates me. I played with this for a
while and put a few things together into a web site on Sudoku.
- For a while I found Kakuro interesting. Unfortunately, the daily Kakuro
puzzles that I come across are not tricky enough to hold your interest after
a while. Again, the mathematics of Kakuro interested me. I put together whatever
I understood into a web site on Kakuro.
- I spend quite a bit of time with my camera, but I'm not really an equipment
buff. I have a glorified point-and-shoot camera, and I try to do a little bit
of post-processing with GIMP: I'm not really an expert at any of these. Here
are some of my photos.
- I try to go
watching once a year. I haven't really learnt to recognize birds in
the wild: I do a little bit of
around Mumbai with my wife and friends and help with
bird lists. I find insects more interesting:
there are so many questions you can ask about them. Recognizing butterflies
is easy, and I like to take
of these colourful creatures. Moths are very hard, but you get a lot of
them in Mumbai, so I occassionally also
moths. I have kept some reports of trips to places
where travellers' tips may be helpful.
- On one of my sabbaticals I learnt some origami. After some inexpert
paperfolding I began to realize why it is fascinating. I also found the
mathematical aspects entertaining: did you know that you can trisect any
angle by paper-folding? As I taught myself this old art I put together a
set of links into a web page of Origami resources
- The Indian Ocean Monsoon
- I really don't know whether this is entertainment or work; I put together
a web page on the monsoon in 1995 and it is
very dated by now. I find the monsoon fascinating, and follow its progress
every year. I also occassionally follow the progress of scientific work on
the monsoon; sometimes I ask students to look at monsoon data.
it is more of entertainment than work.
