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!
