Eight per thousand
Eight per thousand , or otto per mille , is an Italian law under which Italian taxpayers can choose to whom devolve a compulsory 8 ‰ = 0.8% ('eight per thousand') from their annual income tax return between an organized religion recognised by Italy or, alternatively, to a social assistance scheme run by the Italian State. [ 1 ] This declaration is made on the IRE form. People are not required to declare a recipient; in that case the law stipulates that this undeclared amount be distributed among the normal recipients of such taxes in proportion to what they have already received from explicit declarations. In the period from 1990 to 2007 only 42.73%, on average, expressed a choice.
Johann Carl Friedrich Gauss ( pron.: / ɡ aʊ s / ; German : Gauß , pronounced [ɡaʊs] ( listen ) ; Latin : Carolus Fridericus Gauss ) (30 April 1777 – 23 February 1855) was a German mathematician and physical scientist who contributed significantly to many fields, including number theory , algebra , statistics , analysis , differential geometry , geodesy , geophysics , electrostatics , astronomy and optics . Sometimes referred to as the Princeps mathematicorum [ 1 ] ( Latin , "the Prince of Mathematicians" or "the foremost of mathematicians") and "greatest mathematician since antiquity", Gauss had a remarkable influence in many fields of mathematics and science and is ranked as one of history's most influential mathematicians. [ 2 ] He referred to mathematics as "the queen of sciences". [ 3 ] [ edit ] Early years (1777–1798)

Behavior of lines with a common perpendicular in each of the three types of geometry In mathematics , non-Euclidean geometry is a small set of geometries based on axioms closely related to those specifying Euclidean geometry . As Euclidean geometry lies at the intersection of metric geometry and affine geometry , non-Euclidean geometry arises when either the metric requirement is relaxed, or the parallel postulate is set aside. In the latter case one obtains hyperbolic geometry and elliptic geometry , the traditional non-Euclidean geometries.
