The total curvature of a closed curve is always an integer multiple of 2, where N is called the index of the curve or turning number ... |
https://en.wikipedia.org/wiki/Criticism%20of%20nonstandard%20analysis | Nonstandard analysis and its offshoot, nonstandard calculus, have been criticized by several authors, notably Errett Bishop, Paul Halmos, and Alain Connes. These criticisms are analyzed below.
Introduction
The evaluation of nonstandard analysis in the literature has varied greatly. Paul Halmos described it as a tech... |
https://en.wikipedia.org/wiki/European%20Neural%20Network%20Society | The European Neural Network Society (ENNS) is an association of scientists, engineers, students, and others seeking to learn about and advance understanding of artificial neural networks. Specific areas of interest in this scientific field include modelling of behavioral and brain processes, development of neural algor... |
https://en.wikipedia.org/wiki/Siemens%20cycle | The Siemens cycle is a technique used to cool or liquefy gases. A gas is compressed, leading to an increase in its temperature due to the directly proportional relationship between temperature and pressure (as stated by Gay-Lussac's law). The compressed gas is then cooled by a heat exchanger and decompressed, resulti... |
https://en.wikipedia.org/wiki/United%20Kingdom%20Chemistry%20and%20Aerosols%20model | The United Kingdom Chemistry and Aerosols (UKCA) is a community Chemistry-Aerosol-Climate model which are research runs of the Met Office's operational Unified Model. It runs within the Hadley Centre example with multiple flavours of varying horizontal resolutions and vertical layers.
It is a collaboration of the Met ... |
https://en.wikipedia.org/wiki/Electric%20battery | A battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that ... |
https://en.wikipedia.org/wiki/Dimensional%20operator | In mathematics, specifically set theory, a dimensional operator on a set E is a function from the subsets of E to the subsets of E.
Definition
If the power set of E is denoted P(E) then a dimensional operator on E is a map
that satisfies the following properties for S,T ∈ P(E):
S ⊆ d(S);
d(S) = d(d(S)) (d is idemp... |
https://en.wikipedia.org/wiki/Rochon%20prism | A Rochon prism is a type of polariser. It is made from two prisms of a birefringent material such as calcite, which are cemented together.
The Rochon prism was invented by and is named after Abbé Alexis Marie Rochon. It is in many ways similar to the Wollaston prism, but one ray (the ordinary ray) passes through the ... |

https://en.wikipedia.org/wiki/Neptune%20Bank%20Power%20Station | Neptune Bank Power Station was a coal-fired power station situated on the River Tyne at Wallsend near Newcastle upon Tyne. Commissioned in 1901 by the Newcastle upon Tyne Electric Supply Company, the station was the first in the world to provide electricity for purposes other than domestic and street lighting. It was a... |
https://en.wikipedia.org/wiki/Double%20mass%20analysis | Double mass analysis is a simple graphical method to evaluate the consistency of hydrological data. The DM approach plots the cumulative data of one variable against the cumulative data of a second variable. A break in the slope of a linear function fit to the data is thought to represent a change in the relation betwe... |
https://en.wikipedia.org/wiki/S%C3%A9narmont%20prism | The Sénarmont prism is a type of polariser. It is made from two prisms of a birefringent material such as calcite, usually cemented together. The Sénarmont prism is named after Henri Hureau de Sénarmont. It is similar to the Rochon and Wollaston prisms.
In the Sénarmont prism the s-polarized ray (i.e., the ray with... |
https://en.wikipedia.org/wiki/Chartered%20Physicist | Chartered Physicist (CPhys) is a chartered status and a professional qualification for physicists awarded by the Institute of Physics. It is denoted by the postnominals "CPhys".
Description
Achieving chartered status in any profession denotes to the wider community a high level of specialised subject knowledge and p... |
https://en.wikipedia.org/wiki/Protist | A protist ( ) or protoctist is any eukaryotic organism that is not an animal, plant, or fungus. Protists do not form a natural group, or clade, but an artificial grouping of several independent clades that evolved from the last eukaryotic common ancestor.
Protists were historically regarded as a separate taxonomic kin... |
