List of eponymous laws
This i have spoofed from Wikipedia. I was working on something and needed some of the laws. I thought it better be on my blog.
The list of eponymous laws provides links to articles on laws, adages, and other succinct observations or predictions named after a person. In some cases the person named has coined the law - such as Parkinson's law. In others, the work or publications of the individual have led to the law being so named - as is the case with Moore's law. There are also laws ascribed to individuals by others, such as Murphy's law; or given eponymous names despite the absence of the named person.
This list is incomplete; you can help by expanding it.
Amara's law - "We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run". Proposed by Roy Amara.
Amdahl's law - Used to find out the maximum expected improvement to an overall system when only a part of it is improved. Named after Gene Amdahl (born 1922)
Ampère's law - In physics, it relates the circulating magnetic field in a closed loop to the electric current passing through the loop. Discovered by André-Marie Ampère.
Asimov's three laws of robotics - also called, more simply, the Three Rules of Robotics, a set of rules which the fictional robots appearing in the writings of Isaac Asimov (1920–1992) must obey.
First law: A robot may not harm a human being, or, through inaction, allow a human being to come to harm.
Second law: A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
Third law: A robot must protect its own existence, as long as such protection does not conflict with the First or Second Law.
Subsequently, a Zeroth Law was added to precede these three: A robot may not injure humanity, or, through inaction, allow humanity to come to harm.
Avogadro's law - In chemistry and physics, one of the gas laws, relating to the volume and molarity of a gas.
Beer-Lambert law - in optics, the empirical relationship of the absorption of light to the properties of the material the light is travelling through. Independently discovered (in various forms) by Pierre Bouguer in 1729, Johann Heinrich Lambert in 1760 and August Beer in 1852.

Brooks' law - Adding manpower to a late software project makes it later. Named after Fred Brooks, author of the well known tome on Project Management, The Mythical Man-Month.
Clarke's three laws. Formulated by Arthur C. Clarke. Several corollaries to these laws have also been proposed.
First law: When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
Second law: The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Third law: Any sufficiently advanced technology is indistinguishable from magic.
Dilbert Principle - Coined by Scott Adams as a variation of the Peter Principle of employee advancement. Named after Adams' Dilbert comic strip, it proposes that the most ineffective workers are systematically moved to the place where they can do the least damage: management.
Dollo's Law - "An organism is unable to return, even partially, to a previous stage already realized in the ranks of its ancestors." Simply put this laws states that evolution is not reversible.
Duverger's law - After Maurice Duverger. Winner-take-all (or first-past-the-post) electoral systems tend to create a 2 party system, while proportional representation tends to create a multiple party system.
Finagle's law - Generalized version of Murphy's law, fully named Finagle's Law of Dynamic Negatives and usually rendered "anything that can go wrong, will". Not strictly eponymous, since there was no Finagle.
Fitts' Law - A principle of human movement published in 1954 by Paul Fitts which predicts the time required to move from a starting position to a final target area. Fitts' law is used to model the act of pointing, both in the real world, e.g. with a hand or finger, and on a computer, e.g. with a mouse.

Grimm's law - explains correspondence between some consonants in Germanic languages vs. other Indo-European languages. Discovered by Jacob Grimm, (1785 – 1863), German philologist and mythologist and one of the Brothers Grimm.
Hanlon's razor - A corollary of Finagle's law, normally taking the form "Never attribute to malice that which can be adequately explained by stupidity.". As with Finagle, possibly not strictly eponymous.
Hartman's Law of Prescriptivist Retaliation - "any statement about correct grammar, punctuation, or spelling is bound to contain at least one eror".

The greater the number of complaints being aired, the better protected are human rights in that country." Coined by Daniel Patrick Moynihan (1927 - 2003).
Murphy's law - Most commonly formulated as "if anything can go wrong, it will", less commonly "If it can happen, it will happen". Ascribed to Edward A. Murphy, Jr.
Newton's laws of motion - In physics, three scientific laws concerning the behaviour of moving bodies, which are fundamental to classical mechanics. Discovered and stated by Isaac Newton (1643– 1727).
First law: A body remains at rest, or moves in a straight line (at a constant velocity), unless acted upon by a net outside force. This law isn't valid any more (outside classical mechanics) since Einstein showed that the "gravitational attractive force", that was thought to accelerate all free falling bodies, doesn't exist and so it turns out that all free falling bodies "accelerate" on their own without acted upon by any external force. The law is still valid in hypothetical inertial reference frames if one manages to create them.
Second law: The acceleration of an object of constant mass is proportional to the force acting upon it. This law translated from classical mechanics to the real world, to be still valid, has to be preceded by a phrase "In an inertial reference frame". Never mind the difficulty to construct an inertial reference frame. In the times of Newton "absolute space" (while it existed) and all systems that moved with a constant velocity in relation to it were considered inertial reference frames. Removing "absolute space" from physics by Einstein created some problems with finding a suitable inertial reference frame to test the law.
Third law: Whenever one body exerts force upon a second body, the second body exerts an equal and opposite force upon the first body.
Newton's law of cooling - the rate of cooling (or heating) of a body due to convection is proportional to the difference between the body temperature and the ambient temperature.
Occam's razor - States that explanations should never multiply causes without necessity. When two explanations are offered for a phenomenon, the simplest full explanation is preferable. Named after William of Ockham (ca.1285–1349)
Ohm's law - In physics, states that the ratio of the potential difference (or voltage drop) between the ends of a conductor (and resistor) to the current flowing through it is a constant, provided the temperature doesn't change. Discovered and named after Georg Simon Ohm (1789–1854).
Parkinson's law - "Work expands so as to fill the time available for its completion". Coined by C. Northcote Parkinson (1909–1993)
Pareto principle - States that for many phenomena 80% of consequences stem from 20% of the causes. Named after Italian economist Vilfredo Pareto, but framed by management thinker Joseph M. Juran.
Peter principle - "In a hierarchy, every employee tends to rise to his level of incompetence". Coined by Laurence J. Peter (1919–1990)
Poisson's Law of Large Numbers - For independent random variables with a common distribution, the average value for a sample tends to the mean as sample size increases. Named after Siméon-Denis Poisson (1781–1840) and derived from "Recherches sur la probabilité des jugements en matière criminelle et en matière civile" (1837; "Research on the Probability of Criminal and Civil Verdicts").
Ralph's observation - "It is a mistake to allow any mechanical object to realize that you are in a hurry."
Raoult's law - In chemistry, Raoult's law states that the vapor pressure of mixed liquids is dependent on the vapor pressures of the individual liquids and the molar vulgar fraction of each present in solution.
Reed's law is the assertion of David P. Reed that the utility of large networks, particularly social networks, can scale exponentially with the size of the network.
Reilly's law - of Retail Gravitation, people generally patronize the largest mall in the area.
Say's law - attributed to economist Jean-Baptiste Say and contrasted to Keynes' Law (discussed above), saying that "supply creates its own demand," i.e., that if businesses produce more output in a free market economy, the wages and other payment for productive inputs will provide sufficient demand so that there is no general glut.
Stevens' Power Law - In physics this law relates the intensity of a stimulus to its perceived strength. It supersedes the Weber-Fechner law, since it can describe a wider range of sensations. The theory is named after its inventor, S. Smith Stevens (1906–1973).
Stokes' law - an expression for the frictional force exerted on spherical objects with very small Reynolds numbers, named for George Gabriel Stokes, (1819–1903)
Sturgeon's law - "Ninety percent of everything is crud." Derived from a quote by science fiction author Theodore Sturgeon (1918–1985)
Ugol's law, names for Max Ugol, who first formulated it on the alt.sex.bondage newsgroup: "If you ever ask 'Am I the only one who has this kink?' the answer is invariably 'no'."
Verner's law - Stated by Karl Verner in 1875, Verner's law describes a historical sound change in the Proto-Germanic language whereby voiceless fricatives *f, *þ, *s and *x, when immediately following an unstressed syllable in the same word, underwent voicing and became respectively *b, *d, *z and *g.
Weber-Fechner law - This law named after Ernst Heinrich Weber and Gustav Theodor Fechner attempts to describe the human perception of various physical stimuli. In most cases, Stevens' power law gives a more accurate description.
Zipf's law - in linguistics, the observation that the frequency of use of the nth-most-frequently-used word in any natural language is approximately inversely proportional to n, or, more simply, that a few words are used very often, but many or most are used rarely. Named after George Kingsley Zipf (1902–1950), whose statistical work research led to the observation. More generally, the term Zipf's law refers to the probability distributions involved, which are applied by statisticians not only to linguistics but also to fields remote from that.
