Sonar lash, Herr Kapitän. He has made contact.

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

living in about 200 times the radiation that would kill you.

It is affected by gravity, but it is invisible to visible light and all other forms of electromagnetic radiation.

Epsilon rays are a form of particle radiation and are composed of electrons.

As they interact with the medium, they generate a faint light called Cherenkov radiation.

The concept of the big bang can be traced back to the discovery of the microwave background radiation in 1965.

Particle radiation is the radiation of energy by means of fast moving subatomic particles.

The current geographical location of centres around the world should be reviewed.

So why do hot objects glow? Thermodynamics.

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

As the universe cooled, the rest mass energy density of matter came to gravitationally dominate that of the photon radiation.

The acceleration from this curving motion induces the electron to radiate energy in the form of synchrotron radiation.

This signal is caused by cyclotron radiation from electrons that are accelerated in Jupiter's magnetic field.

The scope of initiatives vary according to the political situation in the programme countries.

However, quantum mechanical effects are believed to potentially allow the emission of Hawking radiation at this distance.

The best evidence for dark matter today comes from measurements of something called the cosmic microwave background, the afterglow of the Big Bang, but that's another story.

However, you notice, since empty space gives off radiation, there's actually thermal fluctuations, and it cycles around all the different possible combinations of the degrees of freedom that exist in empty space.

This makes the skin turn paler because less blood reaches the surface, reducing the radiation of heat.

The background radiation is simply too static to be able to be seen under the normal spectral analysis.

Professor Van Allen told me about observations of Venus, that there was intense microwave radiation.

If you are going to Jupiter, you have a very high radiation, you know, environment.

All I need now is to flip on another beam, and the bottom beam is me talking, right?

High energy astronomy is the study of astronomical objects that release EM radiation of highly energetic wavelengths.

Use of depleted uranium weapons was weakening the human species because of the exposure to low level radiation and resulting lowering of immune systems.

Many workers in occupations involving exposure to radiation sources or radioactive material are individually monitored.

The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight.

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.

Because if you can live in radiation that looks like this, that brings up a whole series of interesting questions.

In the 1970s, Stephen Hawking told us that a black hole, even though you think it's black, it actually emits radiation when you take into account quantum mechanics.

Incubation period is the time elapsed between exposure to a pathogenic organism, a chemical or radiation, and when symptoms and signs are first apparent.

BICEP (Background Imaging of Cosmic Extragalactic Polarization) and the Keck Array are a series of cosmic microwave background (CMB) experiments.

Occupational radiation exposures are incurred by several categories of workers who work with radioactive materials or are exposed at work to man made or natural radiation sources.

The vents are emitting a black body radiation an IR signature and so they're able to find these vents at considerable distances.

In every little cubic centimeter of space, whether or not there's stuff, whether or not there's particles, matter, radiation or whatever, there's still energy, even in the space itself.

In 1804, Sir John Leslie observed that a matte black surface radiates heat more effectively than a polished surface, suggesting the importance of black body radiation.

However, you notice, since empty space gives off radiation, there's actually thermal fluctuations, and it cycles around all the different possible combinations of the degrees of freedom that exist in empty space.

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.

Since launching their campaign, they have released the first episode, launched their website on the anniversary of the earthquake on March 11 and on March 21 they will share the second episode of the series on their site.

The ionosphere reacts strongly to the intense X ray and ultraviolet radiation released by the Sun during a solar flare, solar storm or coronal mass ejection.

In the 1970s, Stephen Hawking told us that a black hole, even though you think it's black, it actually emits radiation when you take into account quantum mechanics.

Apart from the widespread contamination of steel products in Mexico and the United States, about 1,000 people were exposed to substantial levels of radiation, with effective doses up to about 250 mSv.

And this is a vector field that I'm drawing, where I'm just randomly picking points and showing the vector of the field at that point, that it's pointed outward, and at any given radius away from the circle, these vectors should be the same magnitude.

In every little cubic centimeter of space, whether or not there's stuff, whether or not there's particles, matter, radiation or whatever, there's still energy, even in the space itself.

During most of a black hole's lifetime, the radiation has a low temperature and is mainly in the form of massless particles such as photons and hypothetical gravitons.
