It appears that the light can even travel when the light canal is bent, or totally twisted. The light appears to be reflected from the inner surface, appearing to go in some sort of zigzag track. You can explain this through traditional electromagnetic light theory as it is used in optical fiber communications.” |
And after these commercials, some experts will tell you that the universe does indeed work the way they taught you in school, and after that they will show you how to make waffles. Stay tuned for this, and more. |

they are coming, by the billions.
| quote: | By KRISTEN BUTLER, UPI.com
Around mid-April, in an event that happens only once every 17 years, billions of cicadas will crawl out of the ground and mate. This 17-year cicada brood is known as Brood II, which lives along the east coast from North Carolina to Connecticut.
The exact time is unknown, but when the ground warms to 64 degrees, sometime between mid-April and late May, residents will be hit with millions of cicadas per square mile, reports CBS News. The males will make their distinctive noise to call for mates, and in a swarm it can sound like a subway train.
The females will lay 400-600 eggs in the ends of twigs, and both adults will die shortly after mating. In the summer, the eggs will hatch and their offspring will burrow into the ground to feed on roots until it's their turn to mate — in 17 years.
"Brood II is a periodic cicada that hatches out every 17 years," said Craig Gibbs, an entomologist at the Wildlife Conservation Society's Queens Zoo. "The specific thing about these 17-year cicadas is they are going to be a very dark colored body. They have really bright red eyes, and they also have bright red wing veins."
The cicadas are harmless to trees and humans. They don't bite, but they do make a lot of noise. After four to six weeks the noise will be gone, and Brood II won't be back until 2030. |

So what's the game plan whenever these things happen? Do people avoid going outside for a while? I can imagine life in a convertible would suck. |

a bit crass, unnecessary, in a thread which promotes intellectual curiosity.
Again, reinforcing my point, TA is 'easily forgettable'. |

There is no point in reading articles about Quantum Theory if you don't have a strong foundation.
Let me help you with that. Here's Dr. Hans Albert Einstein's Nobel Winning paper.
Why, yes of course it's in German.

| quote: | | The photons of a light beam have a characteristic energy proportional to the frequency of the light. In the photoemission process, if an electron within some material absorbs the energy of one photon and acquires more energy than the work function (the electron binding energy) of the material, it is ejected. If the photon energy is too low, the electron is unable to escape the material. Increasing the intensity of the light beam increases the number of photons in the light beam, and thus increases the number of electrons excited, but does not increase the energy that each electron possesses. The energy of the emitted electrons does not depend on the intensity of the incoming light, but only on the energy or frequency of the individual photons. It is an interaction between the incident photon and the outermost electron. Electrons can absorb energy from photons when irradiated, but they usually follow an "all or nothing" principle. All of the energy from one photon must be absorbed and used to liberate one electron from atomic binding, or else the energy is re-emitted. If the photon energy is absorbed, some of the energy liberates the electron from the atom, and the rest contributes to the electron's kinetic energy as a free particle |
