slinky time

I didn't really do anything very physicsy this week, so i decided to play with my little cousins slinky and teach her some laws of physics: waves. she grabbed one end and i ran to the other end of the room with the other end. i swear, the little kid could see the nodes and anti nodes better than i could and she learned everything a whole lot quicker then i had... and she's like 5... ok maybe 10, but same thing. Fun with oscillation. awesome! go physics

poooooool!

so after finals, everyone needed to wind down and have a reason to party. cheeehee. so we chilled at brians for like, 3 and a half hours. i hafta say, sean is pretty good at pool, and kevin chun, but doc doesnt know him, so itz pointless to mention him. so anyways, we used our physics skills to the max to own everyone, well in seanz case, to own and in my case to lose to everyone and scratch on the eight ball.

so we practiced lining up the center of the cue ball and the taget balls so they would go in the hole like in the lab we did SUPPPPERRRR long ago. and it was so fun (the physics of it!) that we're gonna b addicted to pool halls until we graduate. then we can make a decent living in college by hustling people like doc did. auuuuu right.

Engines

So basically, my dad says if i'm going to drive, i need to know how the parts of the car work. When we got to the engine, i could actually tell him stuff! Like the fact that heat goes in, expands so the piston moves, then heat moves out and the piston moves back down. And we could find out how much work it does by finding the area under a PV diagram as well as the efficiency. Of course, a car engine works much faster and the gas expands a lot quicker due to sparks, but it's all basically the same.

The World is Flat

Hey guys, I'm sure a lot of you read The World Is Flat as well. Pretty good huh? Makes you think about real-time conversations with people across the world. Pretty cool! Or the scary reality that hackers and terrorists have advanced technology as well. Anyway, the world is being flattened. Read about it.
