This is more for someone who teaches physics, as opposed to math and stats, but the New York Times yesterday ran an article about the potential for long-term risks of dementia in high school football players. The article contained the following quote:

At all levels, helmets are safer, rule adjustments have made the game less vicious, and awareness of the hidden dangers of football head trauma — among both medical personnel and the players — has greatly improved. The pressure to perform, however, has never been higher for teams and their players, whose ever-rising bulk and speed collide head-on with immovable physics.

“I go back to Einstein and E = mc2,” said Julian Bailes, a former Pittsburgh Steelers neurosurgeon and one of the leading researchers in the neurological effects of football concussions. “The players are definitely much more massive and that’s one factor. But you have 300-pound linemen running 4.3s — and that factor is squared. The impacts that players face today, not just the big ones that everyone sees but the routine ones in the trenches, is what really worries me.”

It looks like Julian Bailes is mis-remembering the actually relevant equation for kinetic energy=1/2mv², and confusing it with Einstein's famous but enrtirely irrelevant formula.
