... appears to be four basic forces at work. Gravity is the weakest of the four but acts over great distances, binding stars and galaxies together. The electromagnetic force is stronger and is responsible for holding atoms and molecules together. As ...

... crystals). A computer processes this information to reconstruct, very accurately, the point inside the patient from which the photons originated. The result is a map of the blood flow in the brain. If the patient is asked to carry o ...

... that is not true with a piece of wood. Good conductors of electricity are often good conductors of heat. Since the atoms are closer together, solids conduct heat better than liquids or gasses. This means that two solid materials in contact ...

... is a probability of it being here and a probability of it being there. This means that they can be represented as on, off, and on and off giving three different states. The sheer number of atoms means that this ...

... law. E.g.: - All measures of exposure of a point radiation source will drop off by the inverse square law. If the radiation exposure is 100mR/hr at 1 inch from a source, the exposure will be 0.01mR/hr at 100 inches. * ...
