Some view the birth of quantum chemistry as starting with the discovery of the Schrödinger equation and its application to the hydrogen atom. However, a 1927 article of Walter Heitler (1904–1981) and Fritz London is often recognized as the first milestone in the history of quantum chemistry. This was the first applicat...

In the 18th century, the term chance was also used in the mathematical sense of "probability" (and probability theory was called Doctrine of Chances).

The analog of Lagrange's theorem for double cosets is false. This means that the size of a double coset need not divide the order of G.

PCR has been applied to many areas of research in molecular genetics: PCR allows rapid production of short pieces of DNA, even when not more than the sequence of the two primers is known. This ability of PCR augments many methods, such as generating hybridization probes for Southern or northern blot hybridization. PCR ...

Such a large generator is not required when an engine directly drives a propeller. The first prototype, a 3-meter (10-feet) long submarine called EMS-1, was designed and tested in 1966 by Stewart Way, a professor of mechanical engineering at the University of California, Santa Barbara.

The same optimizations can be applied to induction variables that are not necessarily linear functions of the loop counter; for example, the loop may be converted to

In computer science, an induction variable is a variable that gets increased or decreased by a fixed amount on every iteration of a loop or is a linear function of another induction variable.For example, in the following loop, i and j are induction variables:

In some cases, it is possible to reverse this optimization in order to remove an induction variable from the code entirely. For example: This function's loop has two induction variables: i and j. Either one can be rewritten as a linear function of the other; therefore, the compiler may optimize this code as if it had b...

In the lossless case, it is possible to show that V ( x ) = V 1 e − j k x + V 2 e + j k x {\displaystyle \ V(x)=V_{1}e^{-jkx}+V_{2}e^{+jkx}\ } and I ( x ) = V 1 Z 0 e − j k x − V 2 Z 0 e + j k x {\displaystyle \ I(x)={\frac {\ V_{1}\ }{Z_{0}}}\ e^{-jkx}-{\frac {\ V_{2}\ }{Z_{0}}}\ e^{+jkx}\ } where k {\displaystyle \ k...

In theoretical computer science, a discrete system is a system with a countable number of states. Discrete systems may be contrasted with continuous systems, which may also be called analog systems. A final discrete system is often modeled with a directed graph and is analyzed for correctness and complexity according t...

In mathematics, especially homological algebra and other applications of abelian category theory, the five lemma is an important and widely used lemma about commutative diagrams. The five lemma is not only valid for abelian categories but also works in the category of groups, for example. The five lemma can be thought ...
