Computer Simulation confirms Physics & Team Tests

http://www.hawkridgesys.com/blog/si...5-tom-bradys-case-solidworks-flow-simulation/

Findings by what appears to be a Seahawks fan who ran the sim:
Just from going from inside to outside resulted in a drop of 1.05 PSI
Adding in friction from the rubbing process (the part Belichick said added 1 PSI) increased the internal temperature of the ball after just 4 and a half minutes to 85 Fahrenheit and a new PSI of 13.1.

With the frictioned up Footballs, the PSI drop once the ball is taken outside is 1.55 PSI to 10.95.

Your facts are no match for the haters' beliefs.

FACTS?! Don't give me no stinkin' facts!

But Bill Nye and NdGT said it couldn't happen!
Unfortunately only people who want to see this will, and that doesn't include Roger Dodger.

some one should tweet that to Riess

Didn't deGrasse Tyson backtrack, at least somewhat? Who else besides Nye (and, as far as I know, he never actually ran an experiment) has said it doesn't make sense, science-wise?

Forget Reiss, somebody send this to the Columbia physics department, along with HeadSmart & the Philip Metzger analysis.

DeGrasse-Tyson's 2nd calculation actually came out very close to the internal ball temperature from the friction test in that computer sim too. Not bad to say he was working with the wrong starting percentage.

And this does not even include the further reduction from a wet ball which both further cools and expands the football, increasing volume and reducing PSI. Headsmart showed this was very significant.

Well, the "sports science" guy (don't know his name) said what BB said "Didn't make sense " and hurt his case. Although since it seems to have spurred all of t hese independent experiments i'd have to disagree.
And didnt some physics professor from Columbia say it couldn't happen naturally?

Why were the Colts balls so high? Hmmmm? Hernia?

They weren't rubbed the same.

I don't get this argument, does friction not cause heat? If I say it does, I don't make sense?

Plus, since when in the **** did theory start trumping experiment? You do an experiment, it doesn't match what you predicted. The experiment is wrong? No, it means you have a mystery to solve and figure out what's missing. Even if it's a well known gas law, it means you've missed some variable, or the experiment may have not been controlled.

But BB says I did an experiment, this is the result and a scientist says it doesn't make sense? WTF. What he observed isn't up for debate as making sense or not. Observations don't make sense, they're just observations. Too much assholery going around.

I DEMAND an immediate flow simulation of the bathroom break by that scurrilous surreptitious scalawag of a ball boy.

Jet fans have been calling Bill , "Ball Bag", since 2001. Sounds like he finally got pizzed off and did something about it.

In rewatching this video I've come to the belief that Bill Nye meant this to be satire all along.

The punchline I think is the Go Seahawks at the end and the evidence is that it is on funnyordie along with how unscientifically he performs his experiments.

He takes the footballs out of the refrigerator and squeezes one and says "Yup, feels about the same".

Thats satire..

(I hope, for science's sake).

His interview on NBC wasn't satire. This video is definitely more entertainment than rigorous scientific experiment but that's always been his schtick. He gives out his scientific information in an entertaining way, without bogging down about the exact details. You just trust that he did the less exciting parts behind the scenes, but you're only seeing the cliff notes on film.

It's never been his schtick to intentionally give out incorrect information for satire or entertainment. I think you give him too much credit.

deGrasse Tyson's calculations, after he re-did them, are in agreement that a pressure drop of a little over 1 psi would have happened.

His statement that the footballs would have had to have been 90 degrees to start out with comes from the mere fact that he accepted this report from ESPN as the truth: "11 of 12 balls were at 2 psi below regulation".

That was Monday, IIRC, when deGrasse Tyson corrected his calculations and made the statement about the 90 degree requirement.

Also Monday, though, Mike Florio cast doubt on the 2 psi claim: "one league source has explained it to PFT, the football intercepted by Colts linebacker D’Qwell Jackson was roughly two pounds under the 12.5 PSI minimum. The other 10 balls that reportedly were two pounds under may have been, as the source explained it, closer to one pound below 12.5 PSI."

To my knowledge, every single scientist who has done the gas pressure/temperature calculation correctly agrees completely on the pressure-induced psi drop that would have happened. They only seem to be in conflict because some of them believe the 2 psi drop is the gospel truth, and indeed the gas pressure/temperature calculation does not get you a 2 psi drop. But... it most certainly does get you a pressure drop in excess of 1 psi.

Bottom line: scientists do not disagree at all about the magnitude of the pressure drop that would have happened due to cooling alone. They are simply relying on different information as to the magnitude of the pressure drop that has to be explained.

There may be differing opinions on other things, such as how much would a wet football expand and how reasonable it would be that you could rub a football to make pressure rise significantly, but those things are in fact irrelevant if Mike Florio's source is right about an average pressure drop is a lot closer to 1 psi than to 2 psi.

I would hope the Columbia investigation will look into the accuracy of the gages in question. I suspect the error bars that need to be put on these results will be huge.
