A block party a BU engineering!

I just came from a block party at BU engineering. Any readers from XKCD there? It had free food, A pool of Oobleck (non newtonian fluid ftw), and we got to show off our recycled go Kart in between. Our was the aluminum one with exposed wires and pink seats, not the red one. Ours runs on electricity....

Re: Childhood crackpot theories

I thought up a couple theories for invisibility in middleschool. One method was basically fiber optic cables wrapped around the object to redirect light around it. few years later... saw it in the newspaper and i was like :evil: But then I lol'd. On a somewhat related note, when I was around four, I...

Re: Quantum ElectroDynamics:QED by Feynman

One interpretation of antimatter (feynman's, kinda) is that it behaves like matter traveling back in time: the repulsion experienced by an electron, when time-reversed, looks like the attraction experienced by an anti-electron. The photon being it's own antiparticle is pretty much the same as sayin...

Yeah, and the point of having a force field is that it isn't like all armor. Its nullifies all incoming projectiles and isn't destroyed. This is about as close as you can get without magic.
