Science and Science Fiction

FYI, I'm teaching my science and science fiction class again this
semester at the University of Wyoming.  Last year's lesson plans
are at http://physics.uwyo.edu/~mbrother/sf/index.html.  I'm updating them for this semester at http://physics.uwyo.edu/~mbrother/sf2008/index.html. 
Since my background is astronomy and I'm teaching the course as a
special topics course in physics, I'm focusing on the physical
sciences.  I discovered a few nice links to vidoes and
world-building construction that can help science fiction writers get
off to a fast start with some of the science research.  I know I
have a lot of typos, so don't bother me about those in last year's
materials, but do point me at interesting/useful sites if you know of
something perfect for one of the weeks.

 Cheers,

Mike
