**Beer-Lambert law**— In optics, the Beer–Lambert law, also known as Beer s law or the Lambert–Beer law or the Beer–Lambert–Bouguer law (in fact, most of the permutations of these three names appear somewhere in literature) is an empirical relationship that relates… …32

**Ideal gas law**— The ideal gas law is the equation of state of a hypothetical ideal gas, first stated by Benoît Paul Émile Clapeyron in 1834. : The state of an amount of gas is determined by its pressure, volume, and temperature according to the equation: : PV =… …33

**Okun's law**— Graph of US quarterly data (not annualized) from 1947 through 2002 estimates a form of the difference version of Okun s law: %Change GNP = .856 1.827*(Change Unemployment Rate). R^2 of .504. Differences from other results are partly due to… …34

**Rayleigh–Jeans law**— In physics, the Rayleigh–Jeans Law, first proposed in the early 20th century, attempts to describe the spectral radiance of electromagnetic radiation at all wavelengths from a black body at a given temperature. For wavelength λ, it is;:B… …35

**Benford's law**— Benford s law, also called the first digit law, states that in lists of numbers from many real life sources of data, the leading digit is distributed in a specific, non uniform way. According to this law, the first digit is 1 almost one third of… …38

**Gauss's law**— In physics, Gauss s law, also known as Gauss s flux theorem, is a law relating the distribution of electric charge to the resulting electric field. It is one of the four Maxwell s equations, which form the basis of classical electrodynamics, and… …39

**Second law of thermodynamics**— The second law of thermodynamics is an expression of the universal law of increasing entropy, stating that the entropy of an isolated system which is not in equilibrium will tend to increase over time, approaching a maximum value at… …40

**Gauss' law for gravity**— In physics, Gauss law for gravity, also known as Gauss flux theorem for gravity, is a law of physics which is essentially equivalent to Newton s law of universal gravitation. Its form is mathematically similar to Gauss law for electricity; in… …
