31Stone–Weierstrass theorem — In mathematical analysis, the Weierstrass approximation theorem states that every continuous function defined on an interval [ a , b ] can be uniformly approximated as closely as desired by a polynomial function. Because polynomials are the… …
32Dirac delta function — Schematic representation of the Dirac delta function by a line surmounted by an arrow. The height of the arrow is usually used to specify the value of any multiplicative constant, which will give the area under the function. The other convention… …
33Partial differential equation — A visualisation of a solution to the heat equation on a two dimensional plane In mathematics, partial differential equations (PDE) are a type of differential equation, i.e., a relation involving an unknown function (or functions) of several… …
34Solon — (ancient Greek: Polytonic|Σόλων, c. 638 BC ndash;558 BC) was an Athenian statesman, lawmaker, and Lyric poet. He is remembered particularly for his efforts to legislate against political, economic and moral decline in archaic Athens. His reforms… …
35Principal components analysis — Principal component analysis (PCA) is a vector space transform often used to reduce multidimensional data sets to lower dimensions for analysis. Depending on the field of application, it is also named the discrete Karhunen Loève transform (KLT),… …
36Nipple — This article is about the anatomical structure. For other uses, see nipple (disambiguation). Nipple A nipple, areola and breast of the human female …
37Stirling's approximation — In mathematics, Stirling s approximation (or Stirling s formula) is an approximation for large factorials. It is named in honour of James Stirling.The formula is written as:n! approx sqrt{2pi n}, left(frac{n}{e} ight)^{n}.Roughly, this means that …
38Textual criticism — Carmina Cantabrigiensia, Manuscript C, folio 436v, 11th century Textual criticism (or lower criticism) is a branch of literary criticism that is concerned with the identification and removal of transcription errors in the texts of manuscripts.… …
39Rounding — This article is about numerical rounding. For lip rounding in phonetics, see Labialisation. For other uses, see Rounding (disambiguation). Rounding a numerical value means replacing it by another value that is approximately equal but has a… …
40The Unreasonable Effectiveness of Mathematics in the Natural Sciences — In 1960, the physicist Eugene Wigner published an article titled The Unreasonable Effectiveness of Mathematics in the Natural Sciences , arguing that the way in which the mathematical structure of a physical theory often points the way to further …
