Ponca City, We Love You writes "There will be a program on applied physics and real time strategy that you might want to watch on television today. Conservation of momentum during elastic and inelastic collisions is one aspect on which to focus as players tackle their opponents. It is of critical importance that the Patriots bring down New York's huge and powerful running back, 6-foot-4, 265-pound Brandon Jacobs. An average-size NFL defensive back's mass combined with his speed — on average, 4.56 seconds for the 40-yard dash — can produce up to 1600 pounds of tackling force. A tackle with half a ton of force may sound like a crippling blow, but the body can handle twice that amount because the player's equipment spreads out the incoming energy, lessening its severity."
Nanotech specialists from Cornell have developed their own take on the "physics" of the Super Bowl by creating the world's smallest trophy, which will be awarded today to a contestant who best explains an aspect of football physics. Just some food for thought while you watch the game on your brand new HD television, though you'd better not be watching it in a church.

theodp writes "For 200 members of the Immanuel Bible Church and their friends, the annual Super Bowl party is over thanks to the NFL, which explained that airing NFL games at churches on large-screen TV sets violates the NFL copyright. Federal copyright law includes an exemption for sports bars, according to NFL spokesman Brian McCarthy, but churches are out of luck. Churchgoers who aren't averse to a little drinking-and-driving still have the opportunity to see the game together in public on a screen bigger than 55 inches."

If this [antiqueathlete.com] is what your foot looks like, sir, then I suggest you seek the help of a professional foot doctor. Your egg-feet will scare the children.

Slashdot seems to be very U.S.-centric. Do you have any plans to be more international in your scope?
Slashdot is U.S.-centric. We readily admit this, and really don't see it as a problem. Slashdot is run by Americans, after all, and the vast majority of our readership is in the U.S. We're certainly not opposed to doing more international stories, but we don't have any formal plans for making that happen. All we can really tell you is that if you're outside the U.S. and you have news, submit it, and if it looks interesting, we'll post it.

Feel free. Though I should point out that Soccer is a contraction of Association Football, there's a good article here http://en.wikipedia.org/wiki/Football_(soccer)#History_and_development [wikipedia.org], and predates American Football by some time - the first rules being codified in the 1850s. The less charitable among us followers of more robust codes tend to call it Wendyball or poofball, mainly because of all the falling over, rolling about and crying that goes on.
Then there's Rugby Union (football), which dates from around the same time, and the bastard child Rugby League, aka the thickhead crashball game. Not to mention a whole host of other games including a number of forms played in Ireland (Gaelic) which have been played for close to 700 years.
Compared to all of these games, American Football can be considered something of a johny-come-lately.
So call it Football if you want, but the rest of the world differentiates different styles of football even if you're not aware of their existence.

The MMA one is a really interesting one when you have Bas Rutten making the scientest jaws drop with the amount of pressure they hit a target. One hit I remember broke the 1000lbs of force and they were telling these guys that they are throwing concussion hits.

We've been metric since before I was born, I'm 31. I'll let you off though as no-one over here seems to have noticed either.

The Patriots had broken a rule that had recently been explicitly laid out by the league. (See article [nydailynews.com]).
Pats fan here. Yes, the Patriots broke the rules and were punished for it, but let's put this into perspective:
The Pats got in trouble for #3, not #1 & 2.
Of course #3 apparently contradicts league guidance on shooting from end zone positions [boston.com] ("but there are no restrictions on shoot
