The Physics of Chuck Norris
Posted on December 5, 2007 by B.J.
I don’t think anyone has done this yet (in either book, lecture or film). But I can pretty much guarantee it would be a huge hit. To get you started I’ve got 10 Chuck Norris facts for you:
- When Chuck Norris does a pushup, he isn’t lifting himself up, he’s pushing the Earth down.
- The Big Bang was just Chuck Norris blowing off some steam.
- If, by some incredible space-time paradox, Chuck Norris would ever fight himself, he’d win. Period.
- Not even light can escape a black hole…but Chuck Norris can.
- Chuck Norris is so fast, he can run around the world and punch himself in the back of the head.
- Outer space exists because it’s afraid to be on the same planet with Chuck Norris.
- Chuck Norris is the only human being to display the Heisenberg uncertainty principle — you can never know both exactly where and how quickly he will roundhouse-kick you in the face.
- Scientists have estimated that the energy given off during the Big Bang is roughly equal to 1CNRhK (Chuck Norris Roundhouse Kick)
- Chuck Norris can divide by zero.
- Newton’s Third Law is wrong: Although it states that for each action, there is an equal and opposite reaction, there is no force equal in reaction to a Chuck Norris roundhouse kick.

Buoyant Force On Area Object Equal To Weight Of Water Displaced
Posted on November 21, 2007 by B.J.
An area object partially immersed in a liquid was buoyed upward Tuesday by a force equal to the weight of the liquid displaced by that object, witnesses at the scene reported.

Einstein’s famous tenet of special relativity — that time slows down on a moving clock — has been verified 10 times more precisely than ever before. The result comes from physicists in Germany and Canada, who have timed the “ticking” of lithium

Since their invention in 2000, exotic materials called metamaterials have revealed many uses such as perfect lenses or invisibility cloaks. But now computer simulations performed by physicists in the UK suggest another application — slowing down a “ra

HOW TO FLY
Posted on November 1, 2007 by B.J.
“The knack of flying is learning how to throw yourself at the ground and miss”
With these words, Douglas Adams helpfully explained concept of flying in his Hitchhiker’s Guide to the Galaxy. But the ground is really big, and, as the Tick so sagely noted, “Gravity is a harsh mistress.” So herein contained is my handy-dandy explanation of how you can impress your friends and family by throwing yourself at the ground and missing:
