Some thoughts about some modern trends in mathematical olympiads that may be concerning. I. The story of the barycentric coordinates I worry about my geometry book. To explain why, let me tell you a story. When I was in high school about six years ago, barycentric coordinates were nearly unknown as an olympiad technique. I… Continue reading Make training non zero-sum

It is counterproductive on many levels to leave them feeling like total idiots. --- Bruce Reznick, "Some Thoughts on Writing for the Putnam" Last February I made… Continue reading An apology for HMMT 2016

## On Problem Sets

(It appears to be May 7 -- good luck to all the national MathCounts competitors tomorrow!) 1. An 8.044 Problem Recently I saw a 8.044 physics problem set which contained the problem Consider a system of $latex {N}&fg=000000$ almost independent harmonic oscillators whose energy in a microcanonical ensemble is given by \$latex {E = \frac… Continue reading On Problem Sets
