https://en.wikipedia.org/wiki/Canonical%20form | In mathematics and computer science, a canonical, normal, or standard form of a mathematical object is a standard way of presenting that object as a mathematical expression. Often, it is one which provides the simplest representation of an object and allows it to be identified in a unique way. The distinction between "... |
https://en.wikipedia.org/wiki/Fisher%27s%20fundamental%20theorem%20of%20natural%20selection | Fisher's fundamental theorem of natural selection is an idea about genetic variance in population genetics developed by the statistician and evolutionary biologist Ronald Fisher. The proper way of applying the abstract mathematics of the theorem to actual biology has been a matter of some debate.
It states:
"The rate ... |

https://en.wikipedia.org/wiki/Optically%20stimulated%20luminescence | In physics, optically stimulated luminescence (OSL) is a method for measuring doses from ionizing radiation. It is used in at least two applications:
Luminescence dating of ancient materials: mainly geological sediments and sometimes fired pottery, bricks etc., although in the latter case thermoluminescence dating is ... |
https://en.wikipedia.org/wiki/Carbanion | In organic chemistry, a carbanion is an anion in which carbon is negatively charged.
Formally, a carbanion is the conjugate base of a carbon acid:
where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp3 carbon), alkenes (at an sp2 carbon), arenes (at an sp2 carbon), and alkynes (at... |
