Mathematics is the study of representing and reasoning about abstract objects (such as numbers, points, spaces, sets, structures, and games). Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine, and the social sciences. Applied mathematics, the branch of mathematics concerned with application of mathematical knowledge to other fields, inspires and makes use of new mathematical discoveries and sometimes leads to the development of entirely new mathematical disciplines, such as statistics and game theory. Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind. There is no clear line separating pure and applied mathematics, and practical applications for what began as pure mathematics are often discovered. ( Full article...)

A
Platonic solid is a
convex
regular polyhedron. These are the three-dimensional analogs of the convex
regular polygons. There are precisely five such figures (shown on the left). The name of each figure is derived from the number of its faces: respectively 4, 6, 8, 12 and 20. They are unique in that the sides, edges and angles are all
congruent.
Due to their
aesthetic beauty and
symmetry, the Platonic solids have been a favorite subject of
geometers for thousands of years. They are named after the
ancient Greek philosopher
Plato who claimed the
classical elements were constructed from the regular solids.
The Platonic solids have been known since antiquity. The five solids were certainly known to the
ancient Greeks and there is evidence that these figures were known long before then. The
neolithic people of
Scotland constructed stone models of all five solids at least 1000 years before Plato. (
