Charlier Polynomials
In mathematics, Charlier polynomials (also called Poisson–Charlier polynomials) are a family of orthogonal polynomials introduced by Carl Charlier. They are given in terms of the generalized hypergeometric function by :C_n(x; \mu)= _2F_0(-n,-x;-;-1/\mu)=(-1)^n n! L_n^\left(-\frac 1 \mu \right), where L are generalized Laguerre polynomials. They satisfy the orthogonality relation :\sum_^\infty \frac C_n(x; \mu)C_m(x; \mu)=\mu^ e^\mu n! \delta_, \quad \mu>0. They form a Sheffer sequence related to the Poisson process, similar to how Hermite polynomials relate to the Brownian motion. See also * Wilson polynomials In mathematics, Wilson polynomials are a family of orthogonal polynomials introduced by that generalize Jacobi polynomials, Hahn polynomials, and Charlier polynomials. They are defined in terms of the generalized hypergeometric function and the ..., a generalization of Charlier polynomials. References * C. V. L. Charlier (1905–1906) ''Über die Darstellung willk ...

Rheology
Rheology (; ) is the study of the flow of matter, primarily in a fluid ( liquid or gas) state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. Rheology is a branch of physics, and it is the science that deals with the deformation and flow of materials, both solids and liquids.W. R. Schowalter (1978) Mechanics of Non-Newtonian Fluids Pergamon The term ''rheology'' was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, from a suggestion by a colleague, Markus Reiner.The Deborah Number The term was inspired by the of |

Vorlesungen über Theoretische Physik
''Lectures on Theoretical Physics'' is a six-volume series of physics textbooks translated from Arnold Sommerfeld's classic German texts ''Vorlesungen über Theoretische Physik''. The series includes the volumes ''Mechanics'', ''Mechanics of Deformable Bodies'', ''Electrodynamics'', ''Optics'', ''Thermodynamics and Statistical Mechanics'', and ''Partial Differential Equations in Physics''. Focusing on one subject each semester, the lectures formed a three-year cycle of courses that Sommerfeld repeatedly taught at the University of Munich for over thirty years. Sommerfeld's lectures were famous and he was held to be one of the greatest physics lecturers of his time. Background Sommerfeld was a well known German theoretical physicist who played a major role in developing old quantum theory. He was renowned as a great teacher of theoretical physics in the early 20th century. Wolfgang Pauli wrote in 1951 that Sommerfeld was "the epitome of the scholar and the teacher". Another ph ...

Persilschein
''Persilschein'' is a German idiom and literally means "Persil ticket" ("Persil" refers to a brand of laundry detergent). To own or have a ''Persilschein'' is akin to having "a clean bill of health" and may refer to the granting of a wide-ranging permission or "carte blanche" to pursue a business or a previously morally or legally suspect interest. Denazification certificates The term ''Persilschein'' dates back to the denazification period in Germany. For a German to be given a ''Persilschein'' meant to be given a certificate that they had a clean political past.Duden online''Persilschein''/ref> Suspected Nazi offenders could be exonerated by statements from others, ideally victims or former enemies of the Nazi regime, and thus accepted as having a good reputation. Colloquially the affected person was said to be "washed clean" of accusations of Nazi sympathies; "cleanliness" in this context meaning "innocent".

Nazi Party
The Nazi Party, officially the National Socialist German Workers' Party (german: Nationalsozialistische Deutsche Arbeiterpartei or NSDAP), was a far-right politics, far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party (; DAP), existed from 1919 to 1920. The Nazi Party emerged from the Extremism, extremist German nationalism, German nationalist, racism, racist and populism, populist paramilitary culture, which fought against the communism, communist uprisings in post–World War I Germany. The party was created to draw workers away from communism and into nationalism. Initially, Nazi political strategy focused on anti–big business, anti-bourgeoisie, bourgeois, and anti-capitalism, anti-capitalist rhetoric. This was later downplayed to gain the support of business leaders, and in the 1930s, the party's main focus shifted to Antisemitism, antisemitic and Criticism of ...
