As the sound starts to pulse and contract, our physicists can tell when a photon is going to be emitted.

The electron the thing that goes around the atomic nucleus held around in orbit, by the way, by the electromagnetic force that's carried by this thing, the photon.

Now it may look like a tasty morsel, or a pig's head with wings but if it's attacked, it puts out a barrage of light in fact, a barrage of photon torpedoes.

(c) Photo neutron interrogation photo induced neutron emission occurs when the energy of an incoming photon (X ray or gamma ray) is above a certain threshold and atoms of low atomic weight undergo photonuclear reactions that emit neutrons.

So to explain that if you've got an elementary particle and you shine a light on it, then the photon of light has momentum, which knocks the particle, so you don't know where it was before you looked at it.

When a tree's done using its leaves its solar collectors, these amazing molecular photon capturing devices at the end of a season, it doesn't pack them up, take them to the leaf reprocessing center and have them melted down to form new leaves.

And so, some of the things that they figured out, some of these individuals figured out in one case, a new commercial building and designs for houses that were accepted by clients a design of a solar space probe experiment a redesign of the linear electron accelerator an engineering improvement to a magnetic tape recorder you can tell this is a while ago the completion of a line of furniture and even a new conceptual model of the photon.
