Open Standard Lover writes "XMPP (eXtensible Messaging and Presence Protocol) has been getting a lot of attention during the last month and it seems that the protocol is finally taking off as a general purpose glue to build distributed web applications. It has been covered that AOL was experimenting with an XMPP gateway for its instant messaging platform. XMPP has been designed since the beginning as an open technology for generalized XML routing. However, the idea of an XMPP application server is taking shape and getting supporters. A recent example shows that ejabberd XMPP server can be used to develop a distributed Twitter-like system."

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.
