https://en.wikipedia.org/wiki/Normalizing%20constant | In probability theory, a normalizing constant or normalizing factor is used to reduce any probability function to a probability density function with total probability of one.
For example, a Gaussian function can be normalized into a probability density function, which gives the standard normal distribution. In Bayes'... |
https://en.wikipedia.org/wiki/Option%20time%20value | In finance, the time value (TV) (extrinsic or instrumental value) of an option is the premium a rational investor would pay over its current exercise value (intrinsic value), based on the probability it will increase in value before expiry. For an American option this value is always greater than zero in a fair market,... |
https://en.wikipedia.org/wiki/Metamictisation | Metamictisation (sometimes called metamictization or metamiction) is a natural process resulting in the gradual and ultimately complete destruction of a mineral's crystal structure, leaving the mineral amorphous. The affected material is therefore described as metamict.
Certain minerals occasionally contain interstiti... |
https://en.wikipedia.org/wiki/Projective%20line | In mathematics, a projective line is, roughly speaking, the extension of a usual line by a point called a point at infinity. The statement and the proof of many theorems of geometry are simplified by the resultant elimination of special cases; for example, two distinct projective lines in a projective plane meet in exa... |

The primary function... |
https://en.wikipedia.org/wiki/Quantum%20solvent | A quantum solvent is essentially a superfluid (aka a quantum liquid) used to dissolve another chemical species. Any superfluid can theoretically act as a quantum solvent, but in practice the only viable superfluid medium that can currently be used is helium-4, and it has been successfully accomplished in controlled con... |
