PHY 3103 is an introduction to two great ideas of 20^th century physics: Einstein's Special Theory of Relativity, and Quantum Mechanics.  By the time you have completed this course, you should be convinced that most of the physics you learned before this class is at best extremely naive, and the universe is a much stranger place than you have imagined (and maybe stranger than you can imagine).  Time permitting, once we have completed an introduction to these two topics, we will go on to a variety of interesting applications of these ideas.
