“What’s the Point: Why Math Really Matters”

with Nira Chamberlain

Wednesday, October 7 at 4:00 pm and 7:00 pm ET (New York)

All around the world, children and even some adults ask the question: “What is the point of mathematics?”  The field of mathematical modeling not only helps answer this question, it can even help quench the human thirst for knowledge.  Join Dr. Nira Chamberlain, Chartered Mathematician, Chartered Scientist, and President of the Institute of Mathematics and its Applications (United Kingdom) as he shares applications of mathematical modeling, from serious to fun.  From the edge of our solar system to battling an artificial intelligence takeover, we will see the point of mathematics after all.

Special introduction by Evelyn Lamb, math and science writer.

This is a live-streamed event.  Occasional video recordings are made available for a fee at
