If watching the lectures on TED just aren't socially stimulating enough for you, you might want to be on the look-out for a Science Cafe.
In an effort to increase the awareness of ordinary Americans in the STEM fields (science, technology, engineering, and maths), the Florida Academy of Sciences, with seed money from WGHB in Boston (the producers of NOVA) have set up Science Cafes.
Like poetry slams and open mic night at comedy clubs, only way, way more intelligent, Science Cafes bring a guest lecturer into a venue--usually one with food--to talk for a while about some science-related topic. If you find yourself lost by the jargon, you can at least enjoy the lattes or hot wings.
So far, cafes have popped up in almost every state in America.
The idea was created in 1998 by the Cafe Scientifique in Leeds, England (trust the Brits to come up with all the cool ideas first!) Of course, if you go back far enough, the educational Chataqua Movement began in the US in the late 1870's, but who cares, at least there's SCIENCE being discussed here!
Not every speaker can be as engaging as Michio Kaku, but the concept seems to be interesting enough to actually catch on.
