HOT HEADS =]

okay so on friday chad and i were standing in the long shave ice line and he was like whoa feel my hair. so i did and it was super hot. then i felt mines and it was hotter! well it's not til this week when we started talking about light that i realized why it was different if we were exposed to the same sun rays. there are two theories...well three after discussing it with him: 1) that i have darker hair because then my hair would have absorbed more light, thus making it hotter than his. 2) because i have more hair so more was absorbed. or 3) i have thicker hair because more surface area would have collected more light making my hair hotter. so what do you think?

WEEE!

How do you get a swing started without a push?
Well you make yourself look like an idiot and start pushing your legs
back and forth like a maniac. Seriously. This perpendicular force, torque, to the swing that you are sitting on makes it move which makes you move since you are on it! The continuous pumping of your legs makes the motion continuous also and thus a happy swing =]
A push doesn't help you get started either, you have to be held up and let go which turns potential (PE=mgh) energy to kinetic (1/2mvsquared) =] and your pumping keeps it going! woooo...now get on a swing and have some PHysics PHun! =P

Thing to think about: is it possible to go completely around the set if the bars allowed you to? well according to the guy on the left it is cause he did it(on a different swing set). HOW is it physically possible?

EW BIRD

okay so i am soo icked out by birds cause i think of all the germs and stuff thus i dont really want to take a picture of one so yeah. k so basically i was sitting by myself and theres the typical gray bird. so i hear this noise and i look at the bird and its shaking its feathers so its all puffed up now and the noise that i heard was the vibration and waves that the bird made by moving its feathers rapidly.
