The human desire to fly had remained both passionate and hopeless until 1903, when the Wright brothers created the first successful flying machine. James Tobin joins Todd to discuss how the Wright brothers approached the problem of how to make an airplane fly, and what made them succeed where others failed. Tobin is author of "To Conquer The Air: The Wright brothers And The Great Race For Flight."

Todd is joined by Hans Van Dongen to discuss his recent study of sleep deprivation. Van Dongen explains how he and his team found that adults who get less than six hours of sleep each night do not feel sleepy, but still perform poorly on standard tests of alertness. Van Dongen is from the University of Pennsylvania School of Medicine at Philadelphia.

Todd talks to Benjamin Radford, editor of "Skeptical Inquiries" Magazine, about critical thinking. Radford explains how we can use critical thinking to assess what we're hearing about the situation in Iraq. Radford wrote "Hoaxes, Myths and Manias."

This Easter is the 50th anniversary of Marshmallow Peeps. Lauren Easterly, Brand Specialist for Peeps, gives Todd some Peeps history, and tells him about the newest flavor that the company introduced for Easter 2003.
