Digital laws

Moore's Law -- The observation made in 1965 by Gordon Moore, co-founder of Intel, that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Moore predicted that this trend would continue for the foreseeable future. In subsequent years, the pace slowed down a bit, but data density has doubled approximately every 18 months, and this is the current definition of Moore's Law, which Moore himself has blessed. Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades.

Kryder's law is the storage equivalent of Moore's Law ,Seagate's vice president of research said back in 2005 that magnetic disk storage density doubles approximately every 18 months.That also means the cost of storage halves every eighteen months, enabling online services to give us more storage without charging any more for it.

Wriths law - Niklaus Wirth has, and in 1995 observed that "software is getting slower more rapidly than hardware becomes faster." Wirth's law has been invoked by, and wrongly credited to, both Google's Larry Page and Microsoft's Bill Gates.

Rule 34—"If it exists, there is porn of it. No exceptions"—is a prevalent meme that Internet pornography exists for every conceivable topic. Rule 34 is one of the best-known Internet adages in current usage.

Fitts's law (often cited as Fitts' law) is a model of human movement primarily used in human–computer interaction and ergonomics that predicts that the time required to rapidly move to a target area is a function of the distance to the target and the size of the target. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor using a pointing device. It was proposed by Paul Fitts in 1954.
