law of nature

n
1. (Philosophy) an empirical truth of great generality, conceived of as a physical (but not a logical) necessity, and consequently licensing counterfactual conditionals
2. (Philosophy) a system of morality conceived of as grounded in reason. See natural law2, nomological2
3. See law18

all-or-none law - (neurophysiology) a nerve impulse resulting from a weak stimulus is just as strong as a nerve impulse resulting from a strong stimulus
principle, rule - a rule or law concerning a natural phenomenon or the function of a complex system; "the principle of the conservation of mass"; "the principle of jet propulsion"; "the right-hand rule for inductive fields"

Avogadro's hypothesis, Avogadro's law - the principle that equal volumes of all gases (given the same temperature and pressure) contain equal numbers of molecules
Bernoulli's law, law of large numbers - (statistics) law stating that a large number of items taken at random from a population will (on the average) have the population statistics
Benford's law - a law used by auditors to identify fictitious populations of numbers; applies to any population of numbers derived from other numbers; "Benford's law holds that 30% of the time the first non-zero digit of a derived number will be 1 and it will be 9 only 4.6% of the time"
Bose-Einstein statistics - (physics) statistical law obeyed by a system of particles whose wave function is not changed when two particles are interchanged (the Pauli exclusion principle does not apply)
Boyle's law, Mariotte's law - the pressure of an ideal gas at constant temperature varies inversely with the volume
Coulomb's Law - a fundamental principle of electrostatics; the force of attraction or repulsion between two charged particles is directly proportional to the product of the charges and inversely proportional to the distance between them; principle also holds for magnetic poles
Dalton's law of partial pressures, law of partial pressures, Dalton's law - (chemistry and physics) law stating that the pressure exerted by a mixture of gases equals the sum of the partial pressures of the gases in the mixture; the pressure of a gas in a mixture equals the pressure it would exert if it occupied the same volume alone at the same temperature
distribution law - (chemistry) the total energy in an assembly of molecules is not distributed equally but is distributed around an average value according to a statistical distribution
equilibrium law, law of chemical equilibrium - (chemistry) the principle that (at chemical equilibrium) in a reversible reaction the ratio of the rate of the forward reaction to the rate of the reverse reaction is a constant for that reaction
Fechner's law, Weber-Fechner law - (psychophysics) the concept that the magnitude of a subjective sensation increases proportional to the logarithm of the stimulus intensity; based on early work by E. H. Weber
Fermi-Dirac statistics - (physics) law obeyed by a systems of particles whose wave function changes when two particles are interchanged (the Pauli exclusion principle applies)
Charles's law, Gay-Lussac's law, law of volumes - (physics) the density of an ideal gas at constant pressure varies inversely with the temperature
Henry's law - (chemistry) law formulated by the English chemist William Henry; the amount of a gas that will be absorbed by water increases as the gas pressure increases
Hooke's law - (physics) the principle that (within the elastic limit) the stress applied to a solid is proportional to the strain produced
Hubble law, Hubble's law - (astronomy) the generalization that the speed of recession of distant galaxies (the red shift) is proportional to their distance from the observer
Kepler's law, Kepler's law of planetary motion - (astronomy) one of three empirical laws of planetary motion stated by Johannes Kepler
Kirchhoff's laws - (physics) two laws governing electric networks in which steady currents flow: the sum of all the currents at a point is zero and the sum of the voltage gains and drops around any closed circuit is zero
law of averages - a law affirming that in the long run probabilities will determine performance
law of constant proportion, law of definite proportions - (chemistry) law stating that every pure substance always contains the same elements combined in the same proportions by weight
law of diminishing returns - a law affirming that to continue after a certain level of performance has been reached will result in a decline in effectiveness
law of effect - (psychology) the principle that behaviors are selected by their consequences; behavior having good consequences tends to be repeated whereas behavior that leads to bad consequences is not repeated
law of equivalent proportions, law of reciprocal proportions - (chemistry) law stating that the proportions in which two elements separately combine with a third element are also the proportions in which they combine together
law of gravitation, Newton's law of gravitation - (physics) the law that states any two bodies attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume, among the Powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
