Six reasoning tools to make hard problems easy
Here are some MIT physics, mathematics, and engineering courses that
I've offered emphasizing a street-fighting approach (the course
materials are available at the given links).
Mathematics (MIT, IAP 2007, 2008, 2009) | OpenCourseWare site.
6.055/2.038. Art of Approximation
in Science and Engineering (MIT, Spring 2008, 2009, 2010) | OpenCourseWare site.
6.003. Signals and Systems
(MIT, Fall 2007)
Lies and Damn Lies (MIT, IAP 2006)
