Award Winning Electronic Explorer Globe by LeapFrog At Amazon on 4-15-2003. More Info This award-winning globe could help children become A+ geography students. The Explorer Globe II is jam-packed with hundreds of facts, trivia, and useful scholastic information about every aspect of the geographical world. It electronically verbalizes everything from area population, capitol city/country, state/province, large bodies of water, currencies, high points, distance, and more. Other remarkable features make the Explorer an even more useful reference tool. It has a world clock that, once set from your home area, will tell the time in every other part of the world. And any country can be selected to hear a sample its national music (yes, Tahiti does have a national anthem). The globe sits on a sturdy base, which features a dashboard full of interactive functions and an attached soft-tipped stylus. This stylus is the key instrument: use it to touch virtually any point on the surface of the globe to retrieve information. Diane Beall Batteries: 4 C batteries required.

ENCYCLOPEDIA U com Lists of articles by category ... Encyclopedia Home Page SEARCH : Julius Plücker Julius Plücker ) was a German mathematician who vastly extended the study of Lamé curves. In projective geometry , Plücker co-ordinates refer to a set of homogeneous co-ordinates introduced initially to embed the set of lines in three dimensions as a quadric in five dimensions. The construction uses 2x2 minor determinants, or equivalently the second exterior power of the underlying vector space of dimension 4. Their study was called line geometry in the nineteenth century. It is now part of the theory of Grassmannians, to which these co-ordinates apply in generality ( k -dimensional subspaces of n -dimensional space).

30. The Discovery Of The Electron evacuated. A friend of his, the German physicist julius plucker (18011868),used such Geissler tubes for electrical experimentation. http://www.3rd1000.com/history/electrons.htm

The Discovery of the Electron Cathode Rays When Leucippus and his disciple Democritus first advanced the notion of atoms, they pictured the atom as the ultimate, indivisible particle. Dalton, over two thousand years later, retained that view. It seemed necessary to suppose the atom to have no internal structure by definition. If the atom would be divided into still smaller entities, then would not those entities be the true atoms? Throughout the nineteenth century this view of the atom as a featureless, structureless, indivisible particle persisted. When the view broke down, it was through a line of experimentation that was not chemical in nature at all. It came about through studies of the electric current. If a concentration of positive electric charge exists in one place and a concentration of negative electric charge exists in another, an electric potential is set up between the two. Under the driving force of this electric potential a current of electricity flows from one point of concentration to the other, this current tending to equalize the concentration. The current flows through some materials more easily than others. For Instance, the various metals are

He was appointed to Bonn in 1829, and became professor of mathematics at Halle in 1834, then at Bonn in 1836. He made important contributions to analytic geometry and physics. He initiated the investigation of geometrical configurations associated with line complexes. In this way of specifying coordinates a point has a linear equation, namely that of all lines through the point while a line has a pair of numbers namely the x and y coordinates of where it cuts the axes. His work on combinatorics considers Steiner type systems. He also introduced the notion of a ruled surface. In 1847 he turned to physics, accepting the chair of physics at Bonn working on magnetism, electronics and atomic physics.

III. EL ELECTRÓN: THOMSON Y MILLIKAN III.1. INTRODUCCIÓN E N EL capítulo anterior vimos cómo, hacia fines del siglo XIX, se logró una descripción unificada de los fenómenos electromagnéticos. Si la luz resulta de la vibración de cargas, la siguiente pregunta a responder es, ¿por qué los átomos emiten luz?, ¿hay algo que vibre dentro de ellos? Como veremos a continuación, la respuesta de la última pregunta es: sí, el electrón. Las primeras evidencias de la existencia de esa partícula son muy antiguas y están asociadas con la electricidad, es decir, con los fenómenos relacionados con el movimiento, acumulación o deficiencia de electrones en la materia. III.2. DESCARGAS A TRAVÉS DE GASES El fenómeno eléctrico más espectacular es el de las descargas entre nubes (los rayos ), que originalmente era asociado al estado de ánimo de algunas deidades; fue Benjamín Franklin el primero en demostrar su naturaleza eléctrica en su famoso experimento con cometas de papel. Sin embargo, los rayos resultaron demasiado esporádicos e incontrolables como para permitir su estudio sistemático. Las descargas eléctricas a través de gases habían sido observadas en el laboratorio por Francis Hauskbee quien, en 1709, reportó la aparición de una luz

Search Inventors The History of the Cathode Ray Tube By Mary Bellis Return to The History of Television CRT and Television Electronic television is based on the development of the cathode ray tube - CRT - which is the picture tube found in modern television sets. A cathode ray tube or CRT is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface. Television sets, computers, automated teller machines, video game machines, video cameras, monitors, oscilloscopes and radar displays all contain cathode-ray tubes. Phosphor screens using multiple beams of electrons have allowed CRTs to display millions of colors. The first cathode ray tube scanning device was invented by the German scientist Karl Ferdinand Braun in 1897. Braun introduced a CRT with a fluorescent screen, known as the cathode ray oscilloscope. The screen would emit a visible light when struck by a beam of electrons. In 1907, the Russian scientist Boris Rosing (see
