The "Announcer" that just arrived has an ad for a new physics course
"designed to include twentieth century physics throughout." It comes on a
$10 CD. (Speaking of CDs, what do you think of the ThinkWell project?)
More info about this calculus-based college level intro physics course is
available at their website <http://www.physics2000.com/>.
What is the feeling of Phys-L about basing first year university physics on
twentieth century physics rather than classical physics?
