Speed Of Light Time Of Day
1,333 wordsOur view of the sky at night is possible because of the emission and reflection of light. 'Light' is the better-known term for the electromagnetic spectrum, which includes waves in the visible, ultra-violet, infra-red, microwave, radio, X-ray and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several overlap each other. Each of these regions in the electromagnetic spectrum represent transverse waves, travelling as electrical and magnetic fields which interac...

Electron Microscope Three Dimensional
871 wordsThe electron microscope has become one of the most widely utilized instruments for materials characterization. An electron microscope is a scientific instrument that allows us to "see" objects so small that they cannot be seen in any other way. (CITE) Electron microscopes have allowed scientists to see individual molecules and atoms for the first time. Most microscopes, including those in schools and laboratories today, are optical microscopes. They use glass lenses to enlarge, or magnify, an im...

Blurred Vision Color Blindness
1,009 words... interpreted, and sight occurs. Light must pass through the covering layers of the retina to reach the layer of rods and cones. There are about 75 to 150 million cones in the human retina. Rods do not detect lines, points, or color. They perceive only light and dark tones in an image. The sensitive rods can determine outlines of objects in almost complete darkness. They make it possible for people to see in darkness or at night. Cones are the keenest of the retina's receptor cells. They detec...

Feet Wide Number One
786 wordsBeing poor in the fifties was not the ordeal it had been during the Depression. Artists scrambled from week to week, month to month, without deep fears of complete ruin, and now they can't recall precisely how they managed. Even memories of first sales are dim. Most of the hard facts about artists' incomes in the fifties float on the currents of Jackson Pollock's legend. According to Tony Smith, Pollock's art earned him about $ 2, 600 in 1950. One sold for $ 6, 000 in 1954; soon afterward, Blue ...

Stimulated Emission Positively Charged
948 wordsLasers HISTORY OF LASER PRODUCTION The roots of laser mechanism are very modern. In 1900 German physicist Max Planck presented an explanation of why the colors of a glowing hot body may change with temperature. He also proposed discrete quantum theory saying that radiations come in discrete quantities called quanta. Therefore radiations are not only a series of waves but a stream of particles called photons. By 1917, Einstein has outlined the principles underlying the production of laser radiati...

It has been believed since 1972 that, in cell membranes, membrane proteins and phospholipids are constantly and widely distributed as following a fluid mosaic model. Then in 1988, a scientist named Kai Simmons, who worked at the European Molecular Biology Laboratory located in Germany, suggested the notion that there exist micro domains, which are enriched with a lot of different kinds of lipids, s...

Pythagorean Theorem Geometric Shapes
491 wordsGeometry was actually first used in ancient Egypt and Babylon at around 2000 BC in both cases. In order for the Egyptians to build such massive structures as the pyramids they had to have made plans for them prior to the actually building, in these plans geometry had to be used. On ancient Babylonian tablets there is evidence that they understood the Pythagorean theorem. The so-called father of Geometry is Euclid a Greek mathematician.

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...
