There is one champion still alive

A local hero of mine, Dr. Lawrence Krauss Chair of the Physics Department of Case Western University in Cleveland, Ohio, has taken up the call-to-arms to protect Ohioans and the rest of the world against crackpots. In our recent "Intelligent design" debacle, creationists attempted to hijack the science education curriculum, and, thanks in no small part to his efforts, were stopped. He has also made a bigger name for himself analyzing science fiction, and is best known for his book "The Physics of Star Trek." If you find a scientific cause that needs a real scientist to refute morons, he is your man.
