Riemann hypothesis and other great conjectures in Mathematics
I wrote a paper Sketchy Tweets: Ten Minute Conjectures in Graph Theory that appeared in the Mathematical Intelligencer about famous conjectures in graph theory, all of which can be tweeted. Many of the big problems in graph theory are easy to state, but very hard to settle. It was great fun writing the article, co-authored with good friend and colleague Richard Nowakowski. We were inspired by Meyniel’s conjecture on the cop number, and we had excess energy from just having published our book The Game of Cops and Robbers on Graphs.
Genius at Play: John Conway’s biography by Siobhan Roberts
I was happy to stumble upon the new book on John Conway’s life and work Genius at Play while I was visiting the Museum of Mathematics in New York City. By the way, the museum is highly recommended. As I like to travel light, I did not buy the hard covered book, but instead bought…
TIFF: Ramanujan biopic and The Martian
I called it! I am either psychic or saavy: Dev Patel will star as Srinivasa Ramanujan in the upcoming biopic The Man Who Knew Infinity, which will be one of the highly sought after galas at the Toronto International Film Festival this year. I actually called for Patel to play Ramanujan in an earlier post… I…
Pale blue dot
Given the historic New Horizon’s mission to Pluto, I reflected back on Carl Sagan’s famous quote concerning an image of Earth as seen from the Voyager 1 spacecraft 6 kilometers miles from home. Sagan greatly influenced the early direction of my career into mathematics and science. After reading this quote, no one can ever say that…
