“[A neuroscientist,] Dr. Provine embodied the spirit of the popular scientist, one who takes his or her pursuits out of the laboratory and into the public square, from university libraries to public libraries, and from lecture halls to radio and television. He was the author of two books for popular audiences, Laughter: A Scientific Investigation (2000) and Curious Behavior: Yawning, Laughing, Hiccupping, and Beyond (2012).” – The Washington Post
