Cosma reviewed Networks, Crowds, and Markets by Easley and Kleinberg for the American Scientist. I have had the book for a while and just haven’t gotten around to reading it yet, but I should. Its a weighty tome, perhaps a bit too weighty to take to the beach (or on a plane, or…). Alex Dimakis said he reads a little bit before going to bed at night. That’s a heavy glass of warm milk. A fun quote from the review:
What game theorists somewhat disturbingly call rationality is assumed throughout—in other words, game players are assumed to be hedonistic yet infinitely calculating sociopaths endowed with supernatural computing abilities.
Ah, game theory. I anticipate experiencing the unease Cosma feels about the “realities behind the mathematics.”
MIT wants to teach math writing. I thought I learned how to write math by having my Phase II paper draft doused liberally in red ink by Prof. Kleiman. But this is something else entirely. I think a more important thing is to help those who work in mathematical fields or who use mathematics. Perhaps this will be a resource that engineering graduate students can use to improve their own writing.
