Interesting links

This time for almost purely informational:

I have stumbled upon a few very interesting links. The first is to a set of Richard Feynman physics lectures captured on video, and restored, paid for and put on the WEB by Bill Gates. At last some of the money I paid for Windows went back to something useful and good.

The second link is to a book caled Physics for Future Presidents. Its WEB site is
http://nortonbooks.typepad.com/physics_for_future_presid/
I dare not to comment on capabilities of presidents of the US, France or Zimbabwe. But I daresay the book should be translated into Polish ASAP.

The third link is to a set of symposiums on astrophysics at London Imperial College http://www3.imperial.ac.uk/astrophysics. The one that caught my attention was a debate on Dark Energy. I hope to live to see the issue resolved. And I do expect that twenty years from now we might look at the current period with some dismay. Or not?
