The first mathematical symbols for arbitrary quantities appeared much later (beginning in the fifth and fourth centuries B.C.) in Greece. Quantities (areas, volumes, angles) were rep-resented in the form of segments, and the products of two arbitrary like quantities were given in the form of...
The Beginning or the End (1947) IMDB * Movie about the making of the atom bomb. One scene pans across academics working on supposedly relevant mathematics: mostly long division of polynomials. Believers (2007) (TV) IMDB *** A movie about a loony cult, whose leader think a PDE and kill...
to wonder where that might lead. Perhaps later might come an appreciation ofmathematical objectswith inconsistent properties, as the truthmakers for preferred mathematical propositions, and a basis for model theory. But this metaphysical extra is certainly not necessary to make a beginning with. ...

A beginning student of mathematics may prefer to assume that A is true and try to discover what else is then true — a sort of one-directional approach. But a proof by contradiction works simultaneously in two directions, mixing together statements (such as A and its consequences) that we ...
Specialized mathematical journals that were organs of different scientific institutions, societies, and associations appeared at the beginning of the 19th century. By the 1970’s more than 250 mathematical journals were being published in the world. The ever-increasing output of such publications has ...

Speiser and Walter (2015) This article provided a discussion of a concrete case in mathematical reasoning, in which a group of learners made sense of fraction division, beginning with a specific, concrete problem that demanded fresh insight. To meet the challenge, several education undergraduates, ...
At the beginning of the last century the astrophysicist Sir J. Jeans used this system to model stellar clusters and galaxies [65] and to study their stability properties. In this context it appears in many textbooks on astrophysics such as [13,26]. If we want to model an ensemble of mas...
