Cosmic Evolution

Eric Chaisson, PhD, of the Harvard-Smithsonian Center for Astrophysics and Smithsonian Astrophysical Observatory, is especially well known for his multidisciplinary approach to the evolution of the cosmos: from sub-atomic particles at the very beginning, to the emergence of galaxies (still difficult to explain), to stars, planets, and life. Each stage represents greater complexity, yet there is an underlying order. Dr. Chaisson is the author of the most widely used astronomy textbook, plus several books for the general reader. His lecture series at the Museum of Science some years back was also very popular.
