https://en.wikipedia.org/wiki/Slipped%20strand%20mispairing | Slipped strand mispairing (SSM, also known as replication slippage) is a mutation process which occurs during DNA replication. It involves denaturation and displacement of the DNA strands, resulting in mispairing of the complementary bases. Slipped strand mispairing is one explanation for the origin and evolution of re... |
https://en.wikipedia.org/wiki/Systems%20for%20Nuclear%20Auxiliary%20Power | The Systems Nuclear Auxiliary POWER (SNAP) program was a program of experimental radioisotope thermoelectric generators (RTGs) and space nuclear reactors flown during the 1960s by NASA.
The SNAP program developed as a result of Project Feedback, a Rand Corporation study of reconnaissance satellites completed in 1954. ... |
https://en.wikipedia.org/wiki/Cap%20product | In algebraic topology the cap product is a method of adjoining a chain of degree p with a cochain of degree q, such that q ≤ p, to form a composite chain of degree p − q. It was introduced by Eduard Čech in 1936, and independently by Hassler Whitney in 1938.

https://en.wikipedia.org/wiki/Uniqueness%20theorem%20for%20Poisson%27s%20equation | The uniqueness theorem for Poisson's equation states that, for a large class of boundary conditions, the equation may have many solutions, but the gradient of every solution is the same. In the case of electrostatics, this means that there is a unique electric field derived from a potential function satisfying Poisson'... |
https://en.wikipedia.org/wiki/A%20Scientific%20Support%20for%20Darwinism | A Scientific Support for Darwinism (And For Public Schools Not To Teach "Intelligent Design" As Science) was a four-day, word-of-mouth petition of scientists in support of evolution. Inspired by Project Steve, it was initiated in 2005 by archaeologist R. Joe Brandon to produce a public response to the Discovery Institu... |
https://en.wikipedia.org/wiki/Rheobase | Rheobase is a measure of membrane potential excitability. In neuroscience, rheobase is the minimal current amplitude of infinite duration (in a practical sense, about 300 milliseconds) that results in the depolarization threshold of the cell membranes being reached, such as an action potential or the contraction of a m... |
https://en.wikipedia.org/wiki/Static%20key | A cryptographic key is called static if it is intended for use for a relatively long period of time and is typically intended for use in many instances of a cryptographic key establishment scheme. Contrast with an ephemeral key.

https://en.wikipedia.org/wiki/Radar%20tracker | A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into tracks. It is particularly useful when the radar system is reporting data from several different targets or when it is necessary to combine the data... |
https://en.wikipedia.org/wiki/Technology%20CAD | Technology computer-aided design (technology CAD or TCAD) is a branch of electronic design automation that models semiconductor fabrication and semiconductor device operation. The modeling of the fabrication is termed Process TCAD, while the modeling of the device operation is termed Device TCAD. Included are the model... |
https://en.wikipedia.org/wiki/Chronaxie | Chronaxie is the minimum time required for an electric current double the strength of the rheobase to stimulate a muscle or a neuron. Rheobase is the lowest intensity with indefinite pulse duration which just stimulated muscles or nerves. Chronaxie is dependent on the density of voltage-gated sodium channels in the cel... |
