NOTE
THAT ACTUAL MEETING DAYS DIFFER FROM WEEK TO WEEK
This
course focuses on what happens when two big chunks of rock and/or ice collide
at what's known as Òcosmic velocity.Ó A tentative schedule of topics weÕll
cover is given below. I highly recommend that you purchase a copy of The New
Solar System (4th edition) at the
Oberlin Bookstore or elsewhere and read the chapters listed below. There is a
lot of extraneous material, but also lots of good information about IMPACTS, so
concentrate on those parts. A few readings from VERSCHUURÕs Impact! The
Threat from Comets and Asteroids and
NORTONÕs Rocks from Space (2nd
ed.) are also listed. One copy of each of these books is on reserve in the
Science Library, plus a single copy of The New Solar System (NSS). The readings from Verschuur and Norton should also
be on e-res, but not the stuff in NSS. You can also find lots of useful info
about impacts etc. on the internet through your favorite search engine. My personal favorite is NASA
Near Earth Objects ProgramÕs website at http://neo.jpl.nasa.gov/ where you can take
potentially hazardous asteroids for a spin around the Solar System!
