"In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for my understanding. I need to have a visual picture in my mind. I'm constantly translating from the math to some intuitive mind's-eye picture."

Brian Greene, Columbia University

Mr. Freed holds degrees from Brown and MIT. He retired in December 2017 from a 35 year career in investment management in New York City. He spent his entire career building mathematical models. Before working on Wall Street, he taught high school math and physics. He also spent one year teaching economics at Union College. As a teacher, he understands that every student learns in his or her own way, and that he must see the subject as the student sees it in order to communicate effectively with them. While some find math easier than others, everyone can learn with the right support.
