"Former IU and Olympic swim coach dies at 83," by Frank Litsky. *The New York Times*, 5 January2004.

This obituary of James "Doc" Counsilman, "perhaps the most innovative swimcoach in American swimming history," quotes Counsilman's recollection thatafter observing and photographing a freestyle swimmer he finally realized heneeded to apply the Bernoulli Principle to the swimmer's technique."Bernoulli's Principle, named for the 18th-century Swiss mathematician whofirst defined it, states that the higher the speed of a flowing fluid or gas,the lower the pressure, and vice versa. That precept became the basis ofCounsilman's 1968 book, *The Science of Swimming*, which was printed inmore than 20 languages and reprinted numerous times."
