Then, when the cosmos reached an age of about 300,000 years and cooled enough for energy to stream through the matter unimpeded, the photons escaped.

The fourth mirror allows for exquisite control of the streams of photons so that they fall almost perpendicular to the instrument's focal plane, ensuring «very good image quality,» Cui says.

One reason: The pattern of gamma - ray photons streaming from the galactic center is clumpy rather than smooth, a strong sign that individual sources of gamma rays (rather than a diffuse cloud of particles that only occasionally interact) may be to blame.

The insight that light sometimes needs to be treated as an electromagnetic wave and sometimes as a stream of energy quanta called photons is as old as quantum physics.

That's no problem, as after the transmission of stream of photons, Alice and Bob can tell each other for which photons their devices were aligned and use only those to define the key.

The ruddy font of photons gilds the marble floor, streaming past the juggler balancing a club on his forehead, the volunteer collecting for tsunami relief, the girl learning to ride a unicycle, the doorway to a nanotechnology lab, the hiding place where Mystery Hunt's coin was found behind a fire hose, as hundreds of students, heading both east and west, follow the path of light.

But quantum theory says that light is simultaneously a wave and a stream of particles called photons.

His team decided to use a sparse stream of photons — particles of light — instead of random numbers to encrypt information.

A prerequisite for quantum networks is the ability to create a stream of single photons on demand and the researchers at the Niels Bohr Institute succeeded in doing exactly that.

This combined nanocrystals - nanoantenna device was able to produce a highly directional stream of single photons all flying to the same direction with a record low divergence angle.

In the traditional view of photosynthesis, the energy carried by photons streaming from the sun is transferred by bouncing from one chlorophyll molecule to the next, a process that ultimately builds simple carbohydrates from water and carbon dioxide.

But it has the paradoxical quality of behaving in two forms — as waves and as streams of particles known as photons — which can make harnessing it for technological purposes a challenge.

For instance, neutrinos stream out from the center of the sun as soon as they are produced, whereas a photon needs thousands of years to work its way out from the core to the sun's brilliant surface.

If they do, the UHECRs should interact with the photons also streaming out of the explosion to form neutrinos with energies in the hundreds of tera - electronvolts.

Out in space, very little disturbs Kepler from its position, except for the photons (light particles) streaming out of the sun that constant bombard the spacecraft.

The photons will interact with the environment and some of them will become high energy and escape and at equilibrium the energy density of the incoming stream and the «trapped» photons will be the same.

when that stream of infrared photons coming from a disk cross section many, many times the size of earth itself — hence that stream coming from almost 5 sides — dead on, above / below / left / right --

Now that I think about it, this is almost exactly like the animation Ira had way back in his blog entry — with streams of photons spraying around and getting absorbed and re-emitted!
