Skeptic: The Feynman-Tufte Principle; April 2005; Scientific American Magazine; by Michael Shermer; 1 Page(s)

I had long wanted to meet Edward R. Tufte--the man the New York Times called "the da Vinci of data" because of his concisely written and artfully illustrated books on the visual display of data--and invite him to speak at the Skeptics Society science lecture series that I host at the California Institute of Technology. Tufte is one of the world's leading experts on a core tool of skepticism: how to see through information obfuscation.

But how could we afford someone of his stature? "My honorarium," he told me, "is to see Feynman's van."
