Why a Perfect Spiral Football Pass Doesn’t Break the Laws of Physics

They, too, were intrigued.

“I played football in completely new York City a long time ago,” said Dr. cost; he attended Stuyvesant High School, which, like Caltech, is actually known for its high-achieving academics along with not its athletics. “I aspired to be mediocre. Never quite got there.”

Dr. Moss was a classmate along with teammate of Dr. Gay’s at Caltech. “I couldn’t play anywhere else,” Dr. Moss said. “The coach gave me a red helmet along with told everyone within the team, ‘Don’t kill the kid with the red helmet.’ True story.”

Dr. cost said he had not thought about that will problem until he along with Dr. Gay met at a scientific conference along with talked about the item.

“I went on to apply some pretty simple mathematics along with do what physicists do,” Dr. cost said. “Which is actually to try along with throw away all of the irrelevant details along with get the heart of something. Throw away the bath water, looking very carefully to make sure there are no babies within the item.”

The first thought experiment was to eliminate the atmosphere by the equations. nevertheless then the only force acting on the football would certainly be gravity, along with that will would certainly act equally on all parts of the ball along with not exert a twisting torque to push the nose down. “the item is actually always going to point within the same direction, because the item’s acting as a gyroscope,” Dr. cost said. “The tip of the nose will not fall over along with go down.”

Clearly, air resistance, along with gravity, was playing a key role — nevertheless not the one that will the simplistic analysis would certainly suggest. “the item’s kind of cool, because you have these two effects, both of which would certainly seem to have nothing to do with what we actually see,” Dr. cost said.

The three scientists were not the first to examine that will phenomenon, along with others showed through wind tunnel experiments along with computer simulations that will thrown footballs do not violate the laws of physics.
