Now a laser is different.

So, Sandage and his collaborators tried very hard to do this.

And let's say there is a certain amount of sunlight that is reaching the Earht.

Direct flash.

I know it sounds wild. There was this

These are normal cells.

Here is another example of something which is this is a little spectrophotometer.

Light is quintessential. Light is life.

Then I understood.

Direct flash. Razor sharp.

And over here you're measuring absorbance, in the vertical axis you measure absorbance.

So let me write down M for molar.

light bulbs, light.

And you were to shine some light in here.

Same deal.

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.

She wanted to relive her glory days.

In addition to that, we've measured the speed of sound.

And you measure its absorbance, and you just get some number here.

What I want to do in this video is to talk a little bit about spectrophotometry.

(Music)

So actually a smaller amount of the radiation in period, in even an given period of time, not even talking about the time you're facing the sun, but in any given moment in time more energy is hitting the Southern Hemisphere than the Northern.

Which is another way of saying something having a constant velocity

I'm the definition of long term.

2, 3 Show specified diffuse and ambient light

The neat thing about this is, you have light source that flickers on and off at about 1,000 hertz, another light source that detects that light at 1,000 hertz, and so you can run this system in broad daylight.

This is going to be a constant the entire way around the ellipse.

That gives you first approximation to the density distribution in space.

It cannot hide behind the black hole.

There's only you in my life ...

Another cause, and actually this is probably the biggedst cause, is if you think about the total amount of sun, so let's talk about the Northern Hemisphere winter.

They turned out to be lightning or sources of electrical power.

She is one part where you find happiness, hope and light.

For directional lights, you specify the limits of how wide the light extends.

List of user programmable constants

I think most of us understand the general idea about life insurance

It's an arbitrary y.

A beam of sunlight came through the clouds.

And this light is created not out of what the material of the neutron leaves out.

CA

And the atoms themselves are quite violent, but if you fire lasers that are precisely tuned to the right frequency, an atom will briefly absorb those photons and tend to slow down.

This is just a tiny part of the sky the Kepler stares at, where it searches for planets by measuring the light from over 150,000 stars, all at once, every half hour, and very precisely.
