NFL Asks Columbia University For Help With Deflate-Gate
An anonymous reader writes with news that the NFL has reached out for some help answering the questions raised by deflate-gate. "Yep, it's for real. The law firm representing the NFL (Paul, Weiss, Rifkind, Wharton & Garrison) has reached out to Columbia University's department of physics to recruit an expert on 'gas physics' to help determine, as has been reported, the 'environmental impacts on inflated footballs.' This is one of those rare times when the jocks turn to the nerds, so fellow fans of molecules and momentum — climb out of that gym locker you were stuffed into — this is our moment. Stand tall. And do the wave....They want to talk to a physicist, I presume, to help determine if a drop in temperature — a slowing of the air molecules inside the football — can explain the low pressure that was found in some of the balls used in the A.F.C. championship game two weeks ago between the New England Patriots and the Indianapolis Colts."
The problem with describing what happens when a ball cools isn't about the gas inside it; that's well understood. The problem is that the container is also affected by temperature and leather is a complicated material. The best answer here is to do a bunch of experiments, not a bunch of calculations.
