The Founders

"The teaching of mathematics is always in crisis, but we at the Math Circle have found a way to bring people of all ages, from 5 to 60, into the great conversation: that on-going dialogue between mind and the world. The deep joys of inventing and discovering math belong to everyone, and the Math Circle has succeeded in providing a forum for the free discussion and play which leads to that joy." --Robert and Ellen Kaplan
