We’re beaming you back to 1964. Richard Feynman, our favorite Bongo-playing, Nobel Prize-winning physicist, reduces science to the barest essentials, to its most fundamental truth. If a theory doesn’t square with experiment, it’s wrong. That holds true for clever theories, elegant theories, and all of the rest.
This clip is just a small outtake from a seven-part lecture series that Feyman presented at Cornell in 1964, and the lectures are all now freely available on the web thanks to Bill Gates. You can watch the full series here, but be warned: you’ll need to download Microsoft’s Silverlight software to watch the lectures.

I get the impression that Richard Feynman never seriously studied the philosophy of science. He is quoted as saying: “Philosophy of science is about as useful to scientists as ornithology is to birds.”
A little disappointing from such a smart man.
did you guys see this video of bill gates discussing philanthropy, commerce and citizenship with his dad? http://f4a.tv/eMRP9i
Of course, the inverse applies. Physicists know about as much about the philosophy of physics as birds do about ornithology…
If Mr. Gates is helping in science project regarding computer then it will be great for students who will learn under them.
i want to watch all series, but do i have to download Microsoft’s Silverlight software to watch them? I don’t like getting extra software on my pc. I was just going to convert flv to avi , will i need this Silverlight software in this case?
I think it’d be a good thing if bill Gates helped in science project relevant to computer technology, It’d be great for studying.
the lectures are raelly interesting for me..
