Physics 2710 – Introductory Modern Physics

 

Fall 2009

 

Physics 2710 is about physical reality that cannot be directly sensed and about phenomena for which the observer is inextricably a part.  In this realm, waves are particles and particles are waves and there is no intrinsic reality until an observer observes it.  While all of this might sound preposterous and metaphysical, there are profoundly important practical consequences—nuclear energy, laser technology, semiconductors and superconductors, and limits to computation, to name a few.  In fact, it is estimated that roughly 1/3 of the economy of the developed world is directly due to quantum mechanics.  In this course, we will examine both the philosophical implications of modern physics as well as how its ideas are used in practical applications.
