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 />
