    This proves that if, as most of us believe, there exist experimenters having a certain amount of free will, then elementary particles must already enjoy their own small share of this valuable commodity. The theorem was proved jointly with Simon Kochen.

Infinite and Infinitesimal Numbers and Games.

Cantor's infinite cardinal numbers are well-known to most mathematicians - his infinite ordinal numbers less so. I shall discuss both types before passing to the larger system of partizan games and surreal numbers that simultaneously generalize both the ordinal and real numbers.

Plenary talks by 
John Conway - Keynote speaker, Evening Banquet
Elwyn Berlekamp - Fibonnaci Plays Billiards
David Wolfe - In Tribute to Martin Gardner

In this talk, I will discuss at least two fun elementary problems:

First, in how many ways can you place stones on an m by n grid so that
each square is adjacent to an odd number of stones?  For example, on a
7 by 5 grid there are exactly two ways:
      ..*..     *...*
      *.*.*     *.*.*
      **.**     .***.
      *...*     *...*
      .***.     **.**
      *.*.*     *.*.*
      *...*     ..*..

(Joint work with Erick Knight, St Peter High School)

For the second problem, it's long been observed (by Dr. Matrix, among
others) that if you multiply the number 123456789 by 2, 4, 5, 7, or 8
that the result permutes all 9 digits:

         123456789 x 2 = 246913578
         123456789 x 4 = 493827156
         123456789 x 5 = 617283945
         123456789 x 7 = 864197523
         123456789 x 8 = 987654312

I will address why this is the case by generalizing the problem to
base b numbers with b-1 digits.
