Mathematics: It's not what it used to be
ABSTRACT: All the mathematical problem solving techniques I had learned when I graduated university with a math degree in 1968 became obsolete in the course of my career. Digital tools available for free in the Cloud now do everything much faster, more accurately, and on far larger datasets, than a human could ever handle. Yet, for all that obsolescence, in recent years I have been involved in projects for a US Intelligence Agency, the US Navy, and the US Army, and have successfully co-founded and launched an educational technology company. What problems was I working on, how did I approach them, and what mathematical skills was I using?
Apart from the startup company (which was in part an offshoot of the Defense Department work), my experience is typical for mathematicians today. For the fact is, while mathematics may not have changed, there has been a revolution in how we do it (and hence how we should teach it).
About the speaker
Café Scientifique is a place where anyone can come to explore the latest ideas in science and technology. The Café provides a forum for debating science issues outside a traditional academic context. We are committed to promoting public engagement with science and to making science accountable - all spoken in plain English. There is no admission charge to attend our events. Building on its great success outside the United States, Café Scientifique Silicon Valley is the first such Café on the West Coast. We meet monthly to discuss a variety of science topics.
