And there we are, I can give them to you.

Who's got the ultraviolet?

They show us a series of fancy machines.

X rays, useful when you go to hospitals.

Now what happened in our history?

Between 1520 and 1867, 12 million, 500 people were moved from high UV to low UV areas in the transatlantic slave trade.

UV

That's where all of the rest of the light in the universe is supposed to go

So I said, But how did you understand what's going on over there?

I can hear if someone points at me with a remote control.

Uh, that is correct. With the ultraviolet light operative, there is no need for your masks.

In the car we Rajkar.

Infrared and ultra violet rays are types of light invisible to the human eye.

She did not smell of Rajkar.

Ultraviolet rays are harmful to us.

So, living at the equator, we got

However, these are just the tip of the iceberg.

So we used ultraviolet A, which doesn't make vitamin D.

Most bees don't perceive red.

So, all the red light you see is what we call blueshifted.

So if we're somewhere in the Northern Hemisphere,

You said it can't stay active in the ultraviolet light.

There is no change in blood flow, in dilatation of the blood vessels.

So we thought we'd just kind of model

Some of us with lightly pigmented skin

Some of us with darkly pigmented skin

You'd have to worry about the amount of radiation that you were looking at.

Ultraviolet rays can cause skin cancer.

And so what we did was we took a bunch of volunteers and we exposed them to ultraviolet light.

It's a story about transformation and connections.

(Laughter)

He put on sunglasses to protect his eyes from ultraviolet rays.

Well, to assess, for example, the state of conservation. See here the face of the

In the winter, when you are skiing in the Alps, you may experience ultraviolet radiation.

And what we've shown is that doing a sham irradiation this is the thick line here this is shining UV on the arm so it warms up but keeping it covered so the rays don't hit the skin.

Protection

Now what you can do is you could subtract this green

And the good thing about perceiving ultraviolet is that you can hear if it's a good day or a bad day to sunbathe, because ultraviolet is a dangerous color, a color that can actually kill us, so I think we should all have this wish to perceive things that we cannot perceive.

EPA ! EPA !

So I decided to continue extending my color senses, and I added infrared and I added ultraviolet to the color to sound scale, so now I can hear colors that the human eye cannot perceive.
