I wouldn't ask they would.

In the retina, there are two different types of light detecting cells rods and cones.

(Louder cheer)

The rods are used for seeing in low light conditions, and there is only one kind of those.

So let me see if I can draw a three dimensional cone.

Polyconic

That's the beauty of democracy.

Now the intersection of this plane, which is now not orthogonal or it's not perpendicular to the axis of this three dimensional cone.

Let's see if we can learn a thing or two about conic sections.

Let's say this is the center of the object path, the center of the circle

When you see a color, each cone sends its own distinct signal to your brain.

I had more than 19 deaths in my area.

(Laughter)

You can see the vehicle approaching a stop sign.

Civil servant. Found dead on the tracks at Battersea station this morning with his head smashed in.

Why on earth are they called conic sections?

But the reality is it doesn't look like that.

Conical

This is the kind of data that we do have.

Here is an example of our aerial camera.

Now that you know what the conic sections are and why they're called conic sections, let's see if we can understand the actual equations of the conic sections a little bit better, and use that knowledge to be able to at least recognize them when we see the equation, and then if we see the equation, know how to plot them.

So this is a bit of a conundrum.

The same properties. The same viscosity.

So the first thing to recognize is that this is a hyperbola and we'll in a few videos, do a bunch of problems where the first point is just to identify what type of conic section we have and then the second step is actually graph the conic section.

Everything is very quiet down there until the observer Reichert see an object in the road

How to shortcircuit the continuum on a five or sixparsec level.

There you go.

And I even know a little bit about ellipses and hyperbolas.

And that's frankly where the word conic comes from.

Maybe I can find some kind of neat 3D application that can do it better than I can do it.

Now we'll talk about how to turn these paths into actual motion commands.

When you went into the cities, train stations, markets and alleyways, you found lots of dead bodies.

. ..he would blow every circuit in his body.

If we said twice as far we would get another conic section.

It comfortably accommodates one teenager and it's shorter than a traffic cone, and it's almost as efficient as a bicycle, as long as you drive it at 15 miles per hour.

And you might wonder why I put it in this form.

And what I want you to notice is the outward path compared to the homeward path, and compare the two.

But the circuitry still works. It's sending us data.

I'm drawing it in such a way that it only intersects this bottom cone and the surface of the plane is parallel to the side of this top cone.

Can you give me the definition of a cone?

And then up here would be the intersection of the plane and the top one.

As just a second example these pyramidal cells, large cells, they can span a significant fraction of the brain.
