British physicist John Tyndall, in the 1850's, made laboratory measurements of the infrared radiation, which is heat.

Cosmic microwave background experiments Subsequent to the discovery of the CMB, hundreds of cosmic microwave background experiments had been conducted to measure and characterize the signatures of the radiation.

Blackbody Radiation

He received high dose radiation to the head.

So, I'm using quite a lot of radiation.

Blackbody Radiation Magnitude Scale

She is treated with surgery, chemotherapy and radiation.

The Laboratory

Let's first look at the relationship of ultraviolet radiation to the Earth's surface.

Look at some of the major latitudinal transgressions people from high UV areas going to low UV and vice versa.

Exposition to radiation gives susceptibility to suffer mutations.

And so even though the universe will last forever, and ordinary matter and radiation will dilute away, there will always be some radiation, some thermal fluctuations, even in empty space.

This is a nuclear proof facility.

They're in the science lab.

The lighter the object, the less radiation.

We don't have to inject anything. We don't need radiation.

Now, this is a spectroscope, OK, on my laboratory bench.

I have a small lab.

I want to go back to the lab.

I took these back to the lab.

If you are going to Jupiter, you have a very high radiation, you know, environment. It's about the same radiation environment close by Jupiter as inside a nuclear reactor.

We also find a precipitate approach in the recent communication from the Commission, which at least has the merit of saying what it is driving at, which is a federal structure for the Eurofed and a single currency.

If you touch that, you could possibly die through radiation poisoning.

Secondly, we have a natural laboratory surrounding the Earth.

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

Harvard Medical School once I was at a talk director of the lab said, In our lab, we have a saying.

If we eliminate cancer the way we're trying to do now, with chemotherapy and radiation, we're bombarding the body or the cancer with toxins, or with radiation, trying to kill it.

And so we built a laboratory in the back of an 18 wheeler trailer, and actually took the laboratory to the field where we could get better samples.

The stain on the lab coat is due to silver nitrate.

And, of course if you can build mice molars in Petri dishes, you can grow human molars in Petri dishes.

This is our femtosecond laser lab.

And we know the solar output's not constant through time.

Quite good. He also invented a word called blas, meaning astral radiation.

This was our laboratory before.

Come on into the secret lab.

Israel Chaos Lab.

He works in the laboratory.

He works in the lab.

It all started in this lab.

They are in a scientific laboratory.

Audience Where's your lab?

They have been tested in the laboratory.

Some of us with darkly pigmented skin live in low UV areas.

There's this piece of wall in Hiroshima that was completely burnt black by the radiation.

It reduces Earth's heat radiation to space, so there's a temporary energy imbalance.
