Wanna Learn Something?????

I (Tim) love stuff like this!!!  It is interesting to know the "why" behind the stuff that we experience all the time but take for granted (that is why I liked Physics in High School.... I DO want to know how fast the car is going when it hits the tree after it rolls down a hill that is 250 metres long with a slope of 35 degrees).

Ten minutes of learning - go!

Ps.  Can I be this dude???  I really wanna be this dude!  :)
