It's very technological, it's very complex, a little daunting.

Maybe not surprisingly, in the deep ocean, where it's mostly blue, the photoreceptors tend to see blue light.

Orange, yellow, pink. Hmm. Blue.

Yellow DB Red.

He's grayblue.

Red light, green light.

The cones, however, are a different story.

Too many sun's rays are harmful to your skin.

When a neutrino hits a water molecule it emits a kind of blue light, a flash of blue light, and by looking for this blue light, you can essentially understand something about the neutrino and then, indirectly, something about the dark matter that might have created this neutrino.

Is it something that can hurt us? It's a bird.

Suppose we have four blocks.

This flash of blue light

The arrow shows you the long axis.

That's the warm colors which show a well sampled region.

The three of us go to the exam together, and we sit down.

This yellow arrow has the length of 15 and this orange arrow has the length of 46

It's just pretty.

Bezukhov, for instance, is blue.

The yellow on there is the Americas dark blue is Africa brown is Europe green is the Middle East and this light blue is South Asia.

It's cobalt blue, a shimmering, beautiful,

He's a Gemini, and his favorite color is blue.

Notice the bluish discolouration.

There are bluebirds in the moonlight

And whenever they made one of the two choices, chose one odor, in this case the blue one over the orange one, we switched on the lights.

We're going to do exactly what we outlined in the previous slide.

He is a promising youth.

You've got to shine blue light on the kid.

(Laughter)

Red light... green light.

Oh, there it is. Now it's back to orange, yellow, pink.

I got from my dad.

Now let's do the two times tables.

So let me draw that.

He is a promising young man.

So, most animals make blue light, and most animals can only see blue light, but this fish is a really fascinating exception because it has two red light organs.

The costumes were red, pink, blue, and so forth.

Now, this one is blue, and that's the color of most bioluminescence in the ocean because evolution has selected for the color that travels farthest through seawater in order to optimize communication.

She paled at the sight.

Do you have any in blue?

I like blue.

If you move your eyes, you're doomed.

A bit more challenging, right? (Laughter)

So let me write that term.

That's about 2500.

So what they do is, they print yuan
