About Rationally Speaking


Rationally Speaking is a blog maintained by Prof. Massimo Pigliucci, a philosopher at the City University of New York. The blog reflects the Enlightenment figure Marquis de Condorcet's idea of what a public intellectual (yes, we know, that's such a bad word) ought to be: someone who devotes himself to "the tracking down of prejudices in the hiding places where priests, the schools, the government, and all long-established institutions had gathered and protected them."

Rationally Speaking podcast: Samuel Arbesman On The Half-Life of Facts


How long does it take for one-half of everything we know about a subject to be proven wrong? Depends on the subject. 45 years, for example, if that subject is cirrhosis or hepatitis.

Samuel Arbesman, applied mathematician and author of "The Half-Life of Facts: Why Everything We Know Has an expiration Date", joins Julia and Massimo to talk about the hidden patterns underlying how fast our understanding of science is changing.

Sam's pick: "The Success Equation: Untangling Skill and Luck in Business, Sports, and Investing."
