GOD bless MIT for such a huge social contribution!!!

All this knowlege for free. AMAZING!

I'm just an average youtube viewer watching MIT stuff for entertainment. lol

[sprattysy]

some really good stuff here

[ienjoyapples]

haha the end..aw i love him like a crazy granduncle

[stavrospod]

he really is the best teacher I have ever seen..he loves what he does+he loves physics=success in teaching and we learn..great lectules..all of them..

some sweet info here

@EclecticSceptic Here's how this process works. When you rub the glass with the fur, the glass gets positively charged. Then, you place the conducting plate on top. Since the plate is insulated from everywhere (glass is an insulator, and so is air), it stays uncharged. When you touch it, however, it finds a path to draw electrons from the earth (through your conducting body) until it negates the charge of the glass. That's the simplified explanation, of course, but it should do.

Your video is a favorite on San Marino

At 30:20, why does he keep touching the metal plate? What does that do?

@stino22 scratch that. Stupid me, I didn't see that it was 10^5, not 10x^5

[stino22]

At around 17:00, should the equation be E = -5x^4? I might be confused, but it's the derivative with respect to x, correct ?
