There are many fine places to explore the history of modern physics on-line. An excellent discussion of the Michelson-Morley experiment has been put together by Michael Fowler of the University of Virginia. You should read this carefully. He follows with a fine overview of relativity; he also refers to a somewhat more mathematical treatment of relativity.

The revolution in the life sciences in the mid and late twentieth century is well covered by on-line information.

The history of genetics in general has a number of informative sites, including MendelWeband the Biotech Chronicles.

The so-called "central dogma" of molecular biology--the idea that there was a material basis for inheritance--is explained in this article by Francis Crick himself.

The development of the atomic bomb, and the implications of nuclear technology for science, society, and morality is explored in a variety of sites. You should spend time with at least one of these:

  • The National Atomic Museum site is worth exploring. In particular, visit the material on the Manhattan Project.
  • The A-Bomb WWW Museum(a Japanese perspective)
  • Many original documents can be viewed at The Nuclear Files .
  • Another rich area for exploration is the history of the digital computer. A good place to begin is the Computer History website.


    *You should bring to your section this week a proposed Final examination essay question. Write a question, using past examinations as a model, that will help you to bring together themes from the entire course.
