Judging Science: Making Judges Scientifically Literate; Eating Like An Animal; Listener Mail

Court cases increasingly deal with complex science and technical issues. And the last time some judges were in a science classroom was before Watson and Crick published the structure of DNA (or at least before the beginning of the Human Genome Project). We'll talk about bringing judges up to science speed with Franklin Zweig and Robert Bell, the chief judge of the Court of Appeals of Maryland. Zweig is the president and Bell is chairman of the board of directors of the Advanced Science and Technology Adjudication Resource, an organization devoted to training judges in science (and the product of a Congressional mandate accompanying the Human Genome Project). Then, in the Ask A Scientist segment, the Wildlife Conservation Society's Paul Calle responds to a listener query about how some animals seemingly eat just about anything without any dire consequences. And we'll take a quick trip through a batch of other questions submitted by listeners. Websites related to this episode include www.einshac.org; www.wcs.org; www.sciam.com/news; blog.sciam.com.

The Limits of Reason

Ideas on complexity and randomness originally suggested by Gottfried W. Leibniz in 1686, combined with modern information theory, imply that there can never be a "theory of everything" for all of mathematics

The Movie in Your Head

Is consciousness a seamless experience or a string of fleeting images, like frames of a movie? The emerging answer will determine whether the way we perceive the world is illusory
