Math and physicists (2)

A while back I asked why physicists know so much math. In this video Prof. Ramamurti Shankar from Yale University teaches differential equations.

We solve DEs by guessing.

I like to watch science documentaries, since I have seen all Horizon and other channel's docs on physics by now ( some of them even twice or more ), I watch introductory physics stuff instead. Prof. Shankar lectures in an entertaining fashion.
