Location SLMath: Eisenbud Auditorium Video Abstract In kindergarten we learned about the integers (Peano axioms); in gram- mar schhol { about pairs of integers (rationals); and then in high school, about the reals (Dedekind cuts). Berlekamp, Conway, Guy discovered and promoted a method (Don Knuth: \Surreal Numbers") of creating all of those and much more { namely games! { in one masterful stroke. Yet the rationals sometimes present obstinate diculties often over- looked. Example. Let 1 < 1 <; : : : ;< m be real numbers, dubbed moduli , m 3. An over 40 years old conjecture states that there exist reals i such that the system (bn1 + 1c; : : : ; bnmc + mc) constitutes a complemen- tary system of m sequences of integers if and only if i = (2m Supplements -- Show Detail

Location SLMath: Eisenbud Auditorium Video Abstract As a graduate student at UCB in the early 1990s, I attended Math275 - Combinatorial Game Theory. I will try to share with the audience how striking it was for me, and likely for others, to attend Elwyn Berlekamp's classes. I will also show how the seed planted at that moment grew in Portugal, years later Supplements -- Show Detail
