18 hours ago · Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement.
18 hours ago · The law Every physical body spontaneously and continuously emits electromagnetic radiation and the spectral radiance of a body, B ν, describes the spectral emissive power per unit area, per unit solid angle and per unit frequency for particular radiation frequencies. The relationship given by Planck's radiation law, given below, shows that with increasing temperature, the total radiated ...
18 hours ago · A proton is composed of two up quarks, one down quark, and the gluons that mediate the forces "binding" them together. The color assignment of individual quarks is arbitrary, but all three colors must be present; red, blue and green are used as an analogy to the primary colors that together produce a white color.

18 hours ago · The theorem is a key concept in probability theory because it implies that probabilistic and statistical methods that work for normal distributions can be applicable to many problems involving other types of distributions. This theorem has seen many changes during the formal development of probability theory.
18 hours ago · The so-called problem of universals is the problem to explain how different things can agree in their features, e.g., how a tomato and a strawberry can both be red. Realists believe that there are universals. They can solve the problem of universals by explaining the commonality through a universal shared by both entities.
