       | I heard that Feynman's lectures weren't written entirely by
       | Feynman, but were actually a collaboration between a bunch of
       | physicists. Is that true? Where can I read about the history of
       | this aspect?

       | Reading through the lectures, you get the sense that it's
       | superhuman to be able to write all of them. Once someone
       | mentioned that it wasn't only Feynman doing the writing, it made
       | a bit more sense.

         | Feynman wrote the notes and delivered the lectures, based on

       | * Jiggling atoms who like to make friends with each other.
       | 
       | * Where do trees come from? (It's not the dirt.)
       | 
       | * Why don't your arms sink through the armrests of your chair?
       | 
       | * How do trains stay on the tracks?
       | 
       | It's an hour of fun science, and especially accessible for anyone
       | who is curious about physics but doesn't enjoy all the equations.

       | Envisioning a responsive open source browser textbook is pretty

       | This is one of my favourite Feynman analogies, right at the

       | Thanks for the link to the downloadable versions. I have the
       | Feynman Lectures loaded on an old iPod and I find them to be an
       | amazing sleep aid. This is not a criticism, they are engaging
       | enough to take my mind off of whatever is keeping me up while
       | also being baffling enough that I fall asleep during the extended
       | sections of blackboard writing sounds. My current set of files is
       | not as good as the recently re-edited Caltech set but I don't
       | want an active Internet device by my bed. Unfortunately they
       | occasionally lead to somewhat stressful dreams of being in
       | college again. It's a risk I am generally willing to take.

         | Feynman's early 1960's undergraduate lectures were tape-
         | recorded and photographed only - they were never filmed or
         | videotaped. But in 1964 Feynman delivered lectures at Cornell,
         | called "Messenger Lectures," and these were _filmed_ by the
         | BBC.[1]
