Surfaces can become porous.

For rough surfaces, though, animals add claws.

What you see here is a jungle scene, and you see the surfaces according to the amount of light that those surfaces reflect.

And what we have here Can everyone see 25 purple surfaces on your left, and 25, call it yellowish, surfaces on your right?

And so we can regrow these surfaces biologically.

Robert Full That's what she did on rough surfaces.

And by doing so, we can differentiate the surfaces.

They love to touch smooth surfaces rather than rough ones.

White surfaces have long edges, black ones have short ones.

I hasten to say that these surfaces are completely artificial.

The monkey is getting more detailed information from these surfaces.

Now you might think for smooth surfaces we get inspiration here.

And you can stitch all sorts of mathematical theorems onto these surfaces.

Dry areas cover more than one third of the Earth's land surfaces.

These are just like the receptors on the surfaces of your cells.

These are the surfaces the monkey is using to manipulate the tool.

No, you can put them on molecular smooth surfaces they don't do it.

RF And they do really well at grabbing onto surfaces with these claws.

So that means that surfaces can intersect themselves, they can become impossibly small.

Visual arts decoration of surfaces and bodies appears to be a human universal.

So these numbers are the numbers which denote the roughness of these surfaces.

If we take its surfaces and fold them again and again and again and again, then after 16 iterations, 16 steps, we end up with 400,000 surfaces and a shape that looks, for instance, like this.

Now, let's see the surfaces according to the quality of light that they reflect.

There's too many surfaces, there's too much detail, one can't see the end state.

I discovered their soft surfaces revealed every ripple of wind in constantly changing patterns.

Sample materials were extracted from the core of the blocks and from their undamaged surfaces.

I project 3D animation on all the four surfaces of the stage which I interact with.

And that is indicated in the pink. We have a couple fingertip surfaces that are larger.

Now just because we have a distributed foot and spines doesn't mean you can climb vertical surfaces.

Smooth surfaces result in specular reflection with practically all of the signal being reflected away from the sensor.

But she actually used these on smooth surfaces two of them to climb up, and pull herself up.

The few surfaces not covered by signs are often clad in a distinctive, dark green gray, striated aluminum siding.

We calculate gradient surfaces, and drive the bot over to a wall where there's a high probability of life.

Rough surfaces cause diffuse reflections in all directions and a significant portion of the signal is returned to the sensor.

Cool roofs are highly reflective surfaces that don't absorb solar heat and pass it on to the building or atmosphere.

These tuned structures allow the spines, friction pads and ultimately the adhesive hairs to grab onto very challenging, difficult surfaces.

And here we see the distortion reflected in the map of the skin surfaces of the hand of the monkey.

If you want to study how a foot works, we're going to have to simulate those surfaces, or simulate that debris.

And again, we can see it in slightly different form there, with the bubble forming and collapsing between those two surfaces.

But imagine what the properties of this limestone block might be if the surfaces were actually in conversation with the atmosphere.

Robert Full It'll go on different surfaces here's sand although we haven't perfected the feet yet, but I'll talk about that later.

So, color enables us to see the similarities and differences between surfaces, according to the full spectrum of light that they reflect.

And under the scanning electron microscope, you can see the surface there really quite different from the other surfaces we looked at.

If a person who has been registered in the system surfaces elsewhere this can be an indication that criminal activities are taking place.

Very high return signals occur when adjacent smooth surfaces form right angles, which cause a double reflection and hence high return signals to the sensor.
