Amara’s law — We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.
Bradford’s law — a pattern described by Samuel C. Bradford in 1934 that estimates the exponentially diminishing returns of extending a library search.
Brooks’ law — Adding manpower to a late software project makes it later.

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. (I loved this one and it’s true)

Classen’s law — Theo Classen’s Logarithmic Law of Usefulness ‘usefulness=log(technology)’. (ex.: Ipad :P)
Conway’s Law — Any piece of software reflects the organizational structure that produced it.
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 law states that evolution is not reversible.
Dunbar’s number — A theoretical cognitive limit to the number of people with whom one can maintain stable social relationships. No precise value has been proposed for Dunbar’s number, but a commonly cited approximation is 150. (that means that I have approximately 400 friends on facebook with no stable social relationship)
Gall’s law — A complex system that works is invariably found to have evolved from a simple system that worked.
Goodhart’s law — When a measure becomes a target, it ceases to be a good measure.
Gresham’s law — Bad money drives good money out of circulation.
Hanlon’s razor — Never attribute to malice that which can be adequately explained by stupidity. Alternately: Do not invoke conspiracy as explanation when ignorance and incompetence will suffice, as conspiracy implies intelligence.
Hofstadter’s law — It always takes longer than you expect, even when you take into account Hofstadter’s Law. (self-referential law).
Hotelling’s law in economics — Under some conditions, it is rational for competitors to make their products as nearly identical as possible.
Hutber’s law — Improvement means deterioration.
Kranzberg’s First Law of Technology — Technology is neither good nor bad, nor is it neutral.
Leibniz’s law — A principle in metaphysics also known as the Identity of Indiscernibles. It states: If two objects have all their properties in common, then they are one and the same object.
Littlewood’s law — States that individuals can expect miracles to happen to them, at the rate of about one per month.
Metcalfe’s law — In communications and network theory, states that the value of a system grows as approximately the square of the number of users of the system.
Moore’s law — An empirical observation stating that the complexity of integrated circuits doubles every 24 months.
Murphy’s law — Anything that can go wrong will go wrong.

Murphy's law. This may also happen - take care 🙂

Okrent’s Law — The pursuit of balance can create imbalance because sometimes something is true.

Pareto principle — States that for many phenomena 80% of consequences stem from 20% of the causes.
Parkinson’s law — Work expands so as to fill the time available for its completion.Or expenditure rises to meet income. In computers: Programs expand to fill all available memory.
Peter principle — In a hierarchy, every employee tends to rise to his level of incompetence.
Premack’s principle — More probable behaviors will reinforce less probable behaviors.
Reilly’s law of retail gravitation — People generally patronize the largest mall in the area.
Roemer’s law — A hospital bed built is a bed filled.
Rothbard’s law — Everyone specializes in his own area of weakness.
Schneier’s Law — Any person can invent a security system so clever that she or he can’t think of how to break it.
Segal’s law — A man with a watch knows what time it is. A man with two watches is never sure.
Stigler’s law — No scientific discovery is named after its original discoverer, named by statistician Stephen Stigler who attributes it to sociologist Robert K. Merton, making the law self-referential.
Sturgeon’s law — Nothing is always absolutely so.
Sutton’s law — Go where the money is. The law is named after bank robber Willie Sutton, who when asked why he robbed banks, is claimed to have answered “Because that’s where the money is.
Wirth’s law — Software gets slower faster than hardware gets faster.
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.

Postscript: Original article is here I have just removed scientific laws because either they are known or they are not interesting :P.
