Note about required textbook for Spring 2009:
The only required text is "Modern Physics" (4th Edition)
by Tipler and Llewellyn, and from online sites in Sept. 2008,
one could purchase a used copy for under $20. Please note
that local bookstores may only stock the new 5th Edition,
which a student can use for this course, and the prices
for Fall 2008 were $122 (new) and $92 (used).
