At the White House with Mira Bhargava and Fields medalist Manjul Bhargava, celebrating Math and the Movies with a screening of 'The Man Who Knew Infinity'. Mira, Manjul's mother, is a formidable mathematician herself. You can read an article that I wrote about them for India Abroad here.

I have been attending the 'Eleventh International School on Mind, Brain and Education on the topic of Dynamical Coupling: From Brain-to-Brain to Social Interaction', at the Ettore Majorana Centre for Scientific Culture, in Erice (Sicily) Italy. THIS was the view from the conference center! We had an amazing week of lively discussions, amazing food, and also visited ancient Greek ruins of Selinunte and Segesta. Thanks to Uri Hasson (Princeton) and Thalia Wheatley (Dartmouth) for inviting me.

Just got back from the Gathering for Gardner in Atlanta, where I had the pleasure of presenting with legendary mathematicians John Horton Conway and Richard Guy (who at 99 1/2 years of age is still as spry as a 25-year old!), together with Martin Gardner's son James Gardner and University of Oklahoma student Nathan Justus on John Conway's famous Game of Life.

John simplified Von Neumann's algorithm based on the idea of self-replicating robots. He did this by modifying the game of Go over 18 months, playing with five or six people until the rules just felt right. An important part of the game was having "persnickety" participants like Richard to make sure that every piece was put in its proper place. John felt that every key aspect of the Life algorithm was discovered during this period. 

Once the Life algorithm was programmed by Richard Guy and his son Michael Guy (John's close friend at Cambridge), most nerds started playing with Life as a computer program. John felt that the computer program turned Life into "a spectator sport", and Richard Guy thought "it went too fast".

So this session was to encourage people to try Life the way John thinks of it... as a manual game.  If you are interested in learning to play the Game of Life manually, just write to me for the directions or look around online. This 1970 article about the Game of Life was one of the most popular in Martin Gardner's years of columns for Scientific American.

For more information about John Conway, "the world's most charismatic mathematician", read this fantastic article by his biographer, Siobhan Roberts.
