"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."
