However, they have these incredible properties,

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

Electroconductive gel for the ultrasound.

If we had a high conducting or... what do you call them?

Charge Percent

And these are both usually also connected to a big box that contains the gel electrophoresis apparatus.

Permittivity of Vacuum

So the sponge is the electrolyte? Yeah.

And we could also produce power cables, to transfer enormous amounts of current between power stations.

Wires transmit electricity.

now look, I need you to stay on the phone.

Doing backup training on my days off.

I made the battery all liquid

And the object that was levitating here is called a superconductor.

He couldn't complete it.

I don't have a phone anymore.

Do you want me to buzz you in?

Tell him we accept.

We gotta tie the GPS to the mainframe.

That is potentially hyperconductive.

John Connor. Prophesized leader of the Resistance.

Copper conducts electricity well.

I'll stay here by the phone.

Volta's battery works at room temperature.

So let's write this down.

Or let me write it this way.

LED light bulbs.

Yes, Sister.

It's got electrolytes.

What are electrolytes?

Electrolytically produced, yes?

For example, I can make a large circular rail here.

I telephoned him the message.

It's far beyond what we currently have.

Bigger samples, less standard error. And that's preferred.

Let's substitute this into our original equation.

We're working on our college essays. Send them in.

It's a superconducting chip. No cooling needed.

Goddamn it. Yeah, it's got electrolytes.

Remember the electrolytes?

So, this hopefully explains the intuition behind what the derivative term is doing.

Also, we see how we measure the aerodynamic efficiency.

But later on we'll see what the difference is.

Let me show you some examples.
