82. POLYHEDRON - LoveToKnow Article On POLYHEDRON louis poinsot discussed these solids in his memoir, Sur les polygones et lespolydres (Journ. Ecole poly. 1810), three of them having been previously http://46.1911encyclopedia.org/P/PO/POLYHEDRON.htm

POLYHEDRON POLYHEDRON Platonic Solids. The names of these five solids are: (1) the tetrahedron, enclosed by four equilateral triangles; (2) the cuba or hexahedron, enclosed by 6 squares; (3) the octahedron, enclosed by 8 equilateral triangles; (4)~ the dodecahedron, enclosed by 12 pentagons; (5) the icosahedron, enclosed by 20 equilateral triangles. These solids played an important part in the geometry of the Pythagoreans, and in their cosmology symbolized the five elements: fire (tetrahedron), air (octahedron), water (icosahedron), earth (cube), universe or ether (dodecahedron). They were also discussed by the Platonists, so much so that they became known as the Platonic solids. Euclid discusses them in the thirteenth book of his Elements, where he proves that no more regular bodies are possible, and shows how to inscribe them in a sphere. This latter problem received tb,e attention of the Arabian astronomer Abul Wef a (10th century A.D.), who solved it with a single opening of the compasses. Mensuration of the Platonic Solids.The mensuration of the regular polyhedra is readily investigated by the methods of elementary geometry, the property that these solids may be inscribed in and circumscribed to concentric spheres being especially useful.

Louis Poinsot né à Paris, le 3 janvier 1777, décédé à Paris le 5 décembre 1859. Louis Poinsot a étudié à l'Ecole Polytechnique ensuite à l'Université de France en 1809. A partir de 1839 et jusqu'à sa mort il a travaillé au Bureau des Longitudes. Ses apports à la géométrie, à la statique et à la dynamique sont importants. Il est l'inventeur de la mécanique géométrique, en étudiant comment un système de vecteurs agissant sur un corps solide peut être remplacé par un vecteur et un couple. Il a écrit en 1809 un travail important sur les polyèdres; il y découvre quatre nouveaux polyèdres réguliers, dont deux apparaissent déjà dans l'oeuvre de Kepler (1619); Poinsot n'était ignorant de celà. En 1810 Cauchy démontra qu'avec cette définition de régularité, l'énumération des polyèdres réguliers est complète. Page précédente Sommaire

88. Level Surfaces. This description of the rotation of a rigid body about a point at rest is due toLouis poinsot 1834, whence the motion is referred to as poinsot Motion. http://kr.cs.ait.ac.th/~radok/physics/b12.htm

. Motion on precribed trajectory Level surfaces. Geoid. Changes of weight. Earth is also only approximately a rotational ellipsoid and weight does not only change along a meridian. Mountains influence the position of rest of a pendulum and its period of oscillation. Moreover: Theoretically, the lines of equal gravitational force (isogams) on Earth's surface should be like parallels of latitude. However, they are different:. For example, on islands in the oceans, the seconds pendulum is longer, the force of gravity, however, larger than along coasts or inside continents, although the mass of water around the islands is not half as dense as the layers of soil under othe observation posts. Hence Earth can only approximately be a rotational ellipsoid. The elevations and depths of the physical surface of Earth - mountains and valleys, continents and oceans - are small indeed in comparison with Earth's size, so that Earth is comparatively smooth like an apple and you can imagine its physical surface in great approximation to have a theoretical surface. However, it cannot be defined by a formula, but must be determined
