Did anyone else see this in the Pittsburgh Post-Gazette today?
The physics of the matter say the Immaculate Reception ball hit TatumMonday, October 18, 2004
By Byron Spice, Pittsburgh Post-Gazette
If you believe Isaac Newton, says John Fetkovich, then you have to believe that the Immaculate Reception was a fair play.
Fetkovich, an emeritus professor of physics at Carnegie Mellon University, certainly believes in Newton, the English mathematician who formulated the laws of gravity and motion three centuries ago.
snipFetkovich exhumed his notes and sketches after reading a story on this page two weeks ago about University of Nebraska physicist Timothy Gay and his new book, "Football Physics." Gay discusses the physics of the Immaculate Reception in his opening chapter and, in an interview, speculated that an analysis of the ball's trajectory might reveal who it bounced off.
A key to such an analysis is a fundamental law of physics called the conservation of momentum. This law says that when two bodies collide, one gains as much momentum as the other one loses. When Tatum hit Fuqua, for instance, he transferred all of his momentum to the running back, leaving Tatum standing and Fuqua flying to the ground.
What Fetkovich needed to figure out was whose momentum was transferred to the football.
