This is where I first offered to wager.

He wanted to know the end result before wagering. It's like telling my local I want to wager on this years Super Bowl on Feb. 03.
Maddie Meyer/Getty Images Science is on Tom's side. On Saturday, Patriots coach Bill Belichick gave a surreal press conference where he explained how the Patriots footballs could have deflated without any illegal action on his team's part. His explanation wasn't the clearest thing I'd ever heard, and I said so in a post covering the press conference. In response to my post, Kirk Hackett, a retired physicist who worked for the Air Force, emailed me to explain exactly how the Patriots' balls could have deflated even when the Colts' balls did not.
It basically comes down to this: The Patriots do something to prepare the balls. Their preparation increases the PSI by 1 pound. Over time that PSI would naturally deflate by a pound once the preparation is done. But the Patriots also hand the ball to the referees, who artificially let out 1 pound. So, then the ball naturally loses about one more PSI, making it underinflated.
Make of that what you will!
Hackett emailed me his credentials after I asked for them. He says, " As far as I go, you might be able to google me. I am retired and used to work at the Air Force Research Laboratory in Directed Energy. At one time, I was President of the Directed Energy Professional Society. As far as academic credentials go, my Bachelors with a physics major is from Dartmouth (1977), and my PhD in Physics is from MIT (1983). I could dig my diplomas out of the closet, but that is a bit of a hassle."
Here is the full email:
Dear Sir,
As a physicist, and having listened to Belichick's press conference earlier today, I can tell that what he said made a lot of sense from a scientist's point of view.
When the football is rubbed and squeezed, work is being done on the ball, and it will get hotter. If you want, describe the heating as due to friction. When the rubbing stops, the ball will cool back to the environmental temperature. The time constant for cooling depends basically on the materials used in the ball, but pigskin is likely a very poor thermal conductor, which would mean longer times, other things being equal.
The air inside the ball, only a few grams in weight, will equilibrate with the walls of the football quite rapidly — seconds.
If the ball is still warmer than the environment when given to the referees, then they will be deflating the ball back to the requested 12.5 psi. By the way, just inflating the ball with a pump adds some heat to it. That is because the air is squeezed until the pressure in the pump is higher than the pressure in the ball before the air goes into the ball. The squeezing heats the air, quite a bit, but the air doesn't have a lot of mass.
So, now when the ball equilibrates with the environment, by cooling, the pressure will decrease, according to the Ideal Gas Law, particularly if the environment is significantly less warm than the environment where the ball was inflated and then checked by the referees. Obviously, it was a lot colder on the football field, and got even colder later in the evening.
This scenario, in my professional opinion, completely explains the data that has been reported.
Differences with the balls used by the Colts could easily be explained by different preparation procedures, or even longer waits between preparation and the referee check. Especially if the the Colts QB, Luck, likes higher initial ball pressure — as has been reported.
Now, I have something bad to say about the media. You pinheads have been convicting Belichick and Brady without the facts or doing an investigation.
Some of you have even gone so far as to demand the Patriots be disqualified from the Super Bowl. Others have called Brady and/or Belichick a liar.
One of your colleagues at BI, Tony Manfred, is a prime offender.
In a just world, you the media, would be apologizing or get sued for everything you own. This was obviously done with malicious intent. Unfortunately, one of the more unjust aspects of press freedom is that the media is shielded from being sued by public figures. That leaves the media free, except by their own restraint, to lie, sensationalize, and slander. I have been noticing less and less restraint by the media.
At the bottom of this message is a simple calculation on the ball pressure, just moving it from inside to outside that I did a few days ago. It is consistent with the study that the Patriots did, but Belichick's press conference provided new details that validated my position even further.
Have a great day!
Sincerely,
Kirk

what is it you believe?
"somebody made an accusation, they're guilty because I think so", and I don't be needing no evidence
I also choose to emphasize evidence (read manipulated press releases) that supports my conclusion, but any evidence that mitigates my preordained conclusion is worthless to me
the Dan Rather school of logic

What more evidence do you want? Brady prefers a deflated ball and his balls are found to be deflated. The colts footballs are not deflated but we are to believe that is because of the way they rubbed them pregame?? Lol.
The pats have a history. Must we got back to them destroying evidence? I can't figure out how seemingly intelligent people become so stupid about their sports teams.
There is about 120 pro sports teams and cheating follows one. Why is that?
The press conferences have been an embarrassment. Be very glad that Goodell and Kraft are boys and he prefers money of the integrity of his league. Otherwise, BB and brady would be sitting this game out. Their actions clearly give them an advantage...and no matter how tough this might be for you to hear...it is cheating.

I think I gave you too much credit in this post
My goodness. I've seen blind fans before at penn st but you are even beyond them.
Not being able to see thr truth, even when it's painfully obvious, is a major willie character flaw.
The saddest part is that your owner has his own personal bitch as commish...so you'll never even know the real facts. Have you listened to former players and former qb's? They are literally laugjing at the pats excuses
