Principles, Laws, and Razors

One of the best Wikipedia pages I’ve ever seen: List of eponymous laws
Some of my favorites, starting with one that isn’t on the Wikipedia page (yet, I’ll check it out)…

Heisenberg uncertainty principle - It is impossible to measure both energy and time (or position and momentum) completely accurately at the same time (source)

Brooks’ law – Adding manpower to a late software project makes it later

Einstein’s General Theory of Relativity – matter causes space to curve

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

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

Pareto principle – States that for many phenomena 80% of consequences stem from 20% of the causes

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

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.
