The devices that computers use are what's called a transistor.

And his thoughts made him reach for Katie.

Volta's battery works at room temperature.

A small, naked bulb gave the only illumination.

This is where the supply of current flows out from, you see?

It's no more than an anode and a cathode separated by an electrolyte, right?

That's a little better. Woman That side is better.

This electrode here, called the gate, controls the flow of current from the source to the drain these two electrodes.

like the one that you can see here in the photo.

And this forces magnesium to de alloy and return to the upper electrode, restoring the initial constitution of the battery.

I'm not dressed!

We can now reach those circuits.

Your electrodes came off last night.

...inside a wellventilated and clean henhouse, the same hen will lay 150 eggs.

I've got a real estate problem.

Miss baum's electrodes must have slipped off again.

One part of the virus grabs a carbon nanotube, the other part of the virus has a sequence that can grow an electrode material for a battery, and then it wires itself to the current collector.

So this is what we did.

This is the place where the meditators you can see it's kind of inspiring.

Naked...

This is the starting point for designing a battery two electrodes, in this case metals of different composition, and an electrolyte, in this case salt dissolved in water.

Naked as a jaybird.

In the 1950s,

He knows more about solar than anyone I know anywhere in the world guaranteed.

The enterprise that dominates the toilet paper of the world and annoys people

He was naked.

Naked.

This is work done with my colleague Helen Mayberg from Emory.

They put electrodes or sensors on my head.

(Laughter)

So this looks something like this.

I'll be back later to attach your electrodes.

We stimulate one place, the other place. We can stimulate lots of places.

She's 16 years old.

I'm naked!

And snowboard naked.

Unfortunately, that's not the case in India.

I was riding bareback.

He.... Naked?

And here we can see him getting the therapy.

And that current, electrical current, is carried by electrons, just like in your house and so on.

The king is naked!

You're always naked!

But I'm not dressed.

This island is just a bare rock.
