... than that of the light emitted from the corresponding atoms in the lab. Furthermore he found that the farther away the galaxy was the more it was shifted toward the red end of the spectrum. Hubble attributed this shift to the doppler effect. Hubble saw this and concluded that all galaxies are rushing away from us and the universe is expanding as a whole. Modern equipment has observed and verified this so-called Hubble expansion exists throughout the observable universe. This shows three important things. First there is no significance to the fact that earth seems to be the center of the universal expansion. In any galaxy it would look as if you were sta ...

... that all things in nature were made up of particles of matter, also known as atoms. He then returned to Woolsthorpe and continued to study light, gravity and mathematics. These studies eventually lead him to some of the greatest discoveries in the history of science. In science his main discovery was that when white light passed through a prism, it was broken up into a broad spectrum of colors. When that spectrum was shone back through another prism that spectrum became a white light again. Next he passed a single color of light through a prism, the color was the same when it came out the other end this led him to believe that white light was composed of all the ...

Bridge Routing Requirements In general, LANs are low-cost, low-delay, high-bandwidth (e.g., 1-10 Mbps) broadcast channels. A bridged LAN environment preserves the low-delay and high-bandwidth feature but its topology may be more dynamic than in a single LAN due to possible bridge or LAN failures and hosts being moved around. Bridge routing algorithms should meet the following requirements: 1) A bridges LAN environment should resemble a single LAN environment as closely as possible. I ...
