Everyone and their niece is emailing me that I should post these. (And Aatish in comments.) And a good thing, too, because it usually takes at least half a dozen emails before I will do anything at all.
In 1964, Richard Feynman gave the Messenger Lectures at Cornell, aimed at a general audience. They were later collected into The Character of Physical Law, a great little book with a depressingly boring cover. Feynman-worship is often overdone, but man, the guy could lecture. And he knew a lot about physics!
The good news is that Bill Gates has now put the full video of the lectures online, as part of Project Tuva. I had to update some software to view them on my Mac, but it seems to be working now.
Lecture Five is about the arrow of time. If you skip ahead to the 18th minute or so, you’ll hear Feynman explain the Boltzmann Brain argument.
Strange that remarks all center around either opinions about this mans’ perceived
level of reputation, or people who don’t like windows, or microsoft complaining about
compatability problems instead of physics? I suppose I need not attempt any further
interaction. Too bad, it would seem like an interesting forum for online discussion.
Michael York: is that what you call a comment about physics?
My previous comment is what I call exaspeation over the lack of comment about physics!
I posted a theory of mine which attempts to explain the force behind gravity. Gravity is
a weak force because of the immense distance from which it is propogated from outside
the universe, which must be of absolute density, and acting on the entire contents of the
universe, in a way which is not directly detectable. I would suppose the mathematicians
would be able to quantify, what the density of that energy would have to be, in order to
generate the gravitational field which causes curvinlinear forces on matter.
