... tried to doubt them, until two American scientists, Micheleson and Moorly performed an experiment in which they discovered that the speed of light is the same to any moving object traveling at any speed in any direction. This means that if someone measures the speed of light from the sun when traveling away from the sun at one mile per hour, or traveling at 500000 kilometers per ... second, the two measurements would be the same. This has a very unusual consequence. Consider this experiment. A person A is observing a train traveling close to the speed of light. Person B is traveling in ...

... asymmetrically with a hole-injecting electrode (usually ITO) on one side, and a low work function, electron injecting metal contact (e.g., aluminum, magnesium or calcium) on the other side. The emission of light is then the result of radiative charge carrier recombination in the polymer as electrons from one side and holes from the other recombine. Electroluminescence from conjugated polymers was first reported in 1990.9 Poly ... the concomitant shrinkage in circuit size could increase the speed and dynamic memory of computers by a factor of 108. Such progress would correspond to forty ...

... that gamma rays are electromagnetic waves and not charged particles. Gamma rays are very similar to radio or light waves except that they have much more energy. Similarities all three; Gamma, alpha and beta, have are that they all come from the nucleus of a radioactive atom. Because gamma rays have no charge and no mass at all, they are able to ... second way in which x-ryas are made is called bremsstrahlung. Whenever charged particles are increased or decreased, an electromagnetic ray is then created. The speed of the electrons is then increased around the nucleus because of the attra...

... This is known as tunneling. This effect can be used to detect very faint magnetic fields in computer circuits. MANUFACTURING SUPERCONDUCTORS Commercial Superconductors Right now, the largest commercial applications of superconductors make use of their capability to conduct electrical current without resistance. In order for a superconductor to be practical for commercial applications, it must be sturdy, reliable, and relatively easy to ... Nath Bose and Albert Einstein. The condensate behaves like 1 atom, even though it is made up of thousands. The team used 2 techniques: first laser coo...
