Finagle's law of dynamic negatives (also known as Melody's law, Sod's Law or Finagle's corollary to Murphy's law) is usually rendered as "Anything that can go wrong, will—at the worst possible moment." The term "Finagle's law" was first used by John W. Campbell Jr., the influential editor of Astounding Science Fiction (later Analog).
Hanlon's razor is a corollary of Finagle's law, named in allusion to Occam's razor, normally taking the form "Never attribute to malice that which can be adequately explained by stupidity." As with Finagle, possibly not strictly eponymous.
Throughout this article, capital letters (such as ,,,,, and ) will denote sets.On the left hand side of an identity, typically, will be the leftmost set, will be the middle set, and
Sod's law, a British culture axiom, states that "if something can go wrong, it will". The law sometimes has a corollary: that the misfortune will happen at "the worst possible time" (Finagle's law). The term is commonly used in the United Kingdom (while in many parts of North America the phrase "Murphy's law" is more popular). [1]
The notion of positive and negative rights may also be applied to liberty rights. To take an example involving two parties in a court of law: Adrian has a negative right to x against Clay, if and only if Clay is prohibited to act upon Adrian in some way regarding x.
What most people call Murphy's Law is actually Finagle's Law, and despite the name, Finagle's Law doesn't follow from the specific version of Murphy's Law. On the other hand, the Murphy's Law article is already about Finagle's Law, and the original statement of Murphy's Law is now little more than a footnote in the public mind.
The law of experience holds that machines under input tend to lose information about their original state, and the law of requisite variety states a necessary, though not sufficient, condition for a regulator to exert anticipatory control by responding to its current input (rather than the previous output as in error-controlled regulation).
What follows are two results which will imply that an extended signed measure is the difference of two non-negative measures, and a finite signed measure is the difference of two finite non-negative measures. The Hahn decomposition theorem states that given a signed measure μ, there exist two measurable sets P and N such that: P∪N = X and P ...
