Science and Medicine Series<br />
Classroom 129<br />
Professor Peter Fedders<br />
Coordinator: Jack Holtzman<br />
Elements of Modern Physics<br />
This series of four lectures will be a nonmathematical<br />
presentation of ideas in modern<br />
physics that stress the history, basic physical<br />
concepts, philosophy, and current areas of<br />
investigation. Where possible, analogies will be<br />
used to explain the science. This presentation will<br />
be aimed at the level of the intelligent layperson.<br />
January 15<br />
Special and General Relativity. Special relativity<br />
deals with particles traveling near the speed of light,<br />
while general relativity deals with matter and light<br />
in intense gravitational fields such as in proximity to<br />
black holes. Both of these extremes mix space and<br />
time into what is now referred to as “spacetime.”<br />
February 12<br />
Quantum Mechanics. Quantum Mechanics unites<br />
both the particle-like and wave-like properties of all<br />
matter, including light. It has led to an understanding<br />
of atoms, molecules, chemistry, modern electronics,<br />
molecular biology, and virtually all phenomena at the<br />
submicroscopic level.<br />
February 26<br />
Particle Physics. Particle (high energy) physics<br />
seeks to describe nature and to unify all matter in<br />
terms of a few fundamental entities. Entities such<br />
as quarks, gluons, strings, the Higgs, and other<br />
exotic-sounding names will be discussed.<br />
March 12<br />
Cosmology. Probably the part of physics (or<br />
even science) most enticing to the public today<br />
is cosmology, or the study of the universe. Topics<br />
including dark energy, dark matter, the beginning<br />
of the universe, and its ultimate end will be<br />
presented.<br />
Peter Fedders is professor emeritus of physics<br />
at Washington University in St. Louis and was<br />
a consultant on fusion at Laurence Livermore<br />
National Laboratory. He also consulted on clean<br />
energy at the University of Hawaii. He is currently a<br />
docent at the Museum of Natural History in Balboa<br />
Park and for decades has been interested in and<br />
followed the evolution of man and the nature of<br />
the universe.<br />
