  • Electromagnetic Radiation - 778 words
    Electro-Magnetic Radiation Electromagnetic Radiation Electromagnetic radiation is defined as the emission and transmission of energy in the form of electromagnetic waves (Chang, pp. 246). An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves of sound, which scientists have categorized in order to depict the usefulness of the different properties. Theoretically electromagnetic waves can be as long as the expansive width of the universe in one wave, to a wavelength the size of a quanta (the smallest amount of energy that can ...

  • Albert Eienstein - 426 words
    Albert Eienstein ALBERT EINSTEIN The German-American physicist Albert EinsteiN, contributed more than any other scientist to the 20th-century . Born in the town of Ulm, Germany, Mar. 14, 1879, HE then later died in Princeton, N.J., Apr. 18, 1955. In the wake of World War I, Einstein's theories, especially his theory of relativity, seemed to many people to point to a pure quality of human thought, one far removed from the war and its aftermath. Seldom has a scientist received such public attention for having the ability for learning thet he had. in 1905, Einstein examined the phenomenon discovered by Max Planck, according to which electromagnetic energy seemed to be emitted from radiating obj ...

    ALBERT EINSTEIN Does the word quantum mechanics mean anything to you, well it should. What about E=MC2, all of this are very important to you but you may not know it. These theories were all developed by a very intellectual person, Albert Einstein. Albert Einstein is very important to the development of our country and the world. Albert Einstein started his life in Ulm, Germany, march 14, 1879. Einstein's parents were nonobservant Jews. They moved from Ulm to Munich when Albert was an infant. They had a family business of the manufacture of electrical apparatus. The company failed in 1894. So the family moved to Milan, Italy. At this time Albert had decided to give up his German citizenship. ...

    Albert Einstien Men and Women of Science Albert Einstein Early Life Einstein was born in Ulm, Germany on Mar. 14, 1879. Einstein's parents, who were non observant Jews, moved from Ulm to Munich, Germany when Einstein was an infant. The family business was the manufacture of electrical parts. When the business failed, in 1894, the family moved to Milan, Italy. At this time Einstein decided officially to end his German citizenship. Within a year, still without having completed secondary school, Einstein failed an examination that would have allowed him to pursue a course of study leading to a diploma as an electrical engineer at the Swiss Federal Institute of Technology. He spent the next year ...

  • Black Holes - 797 words
    Black Holes Black Holes There are many strange and wonderful phenomenons being discovered throughout our Universe. One of the most intriguing is the concept of a black hole in space. Astronomers have discovered a black hole just 1,600 light years away from Earth. The National Radio Astronomy Observatory cataloged this black hole in the constellation Sagittari on a star called V4641. A black hole is one form of a dead star. A star has three choices when it dies, it can: shrink until it is a white dwarf, shrink until it is a neutron star, or keep on shrinking until it is a point in space with an infinite density known as a black hole. A black hole is an extremely dense outer space body that ha ...

    ... inclination i of the system, and several important things can be calculated. The mass function f(M) = M2^3 sin i / (M1 +M2)^2 gives a relation between the masses of the two bodies, and the semi-major axis a1=AM2/(M1+M2)^2 sin i (where A is the separation of the centers of mass) gives the size of the orbit, which can also be related to the rotational velocities of the stars. A spectroscopic binary with no visible companion would be a candidate for a black hole, and if the dim star's mass is determined to be greater than that of the visible star, it would be a promising candidate. However, this method consists of many uncertainties. Although there were no hard cases for black holes any sci ...

  • Electro Magnetism - 438 words
    Electro Magnetism Electromagnetism defined as "magnetism produced by an electric current". In other words it is the electricity part of what holds ourselves and every bit of matter in the universe together. This source of universal "glue" is found within atoms themselves. As the name sounds, there are two different forces within electromagnetism - the electric force and the magnetic force. Before the early part of the last century, scientist studied electricity and magnetism as different sciences. No one knew the connection between them. Electromagnetism was found almost by accident, that a" flow of electric current (a movement of electrical charge) creates a magnetic force" to use the words ...

A firestorm is violent, has raging winds, and has extremely high temperatures; but fortunately it does not spread very rapidly. The second type is called a conflagration. A conflagration is when the fire spreads in a front (International Physicians for the Prevention of Nuclear War, 1982). The thermal radiation produced by the atomic bomb's explosion will account for most of the deaths or injuries. In Hiroshima and Nagasaki the thermal radiation accounted for approximately twenty to thirty percent of the deaths or injuries from the atomic bomb ...

  • Fiber Optics - 585 words
    Fiber Optics Fiber optics is a branch of optics concerning the transmission of light by means of optical fibers, which are thin strands of glass or other optically transparent materials. Optical fibers can be used to guide light--which is electromagnetic radiation in a certain frequency range--in much the same way that metal wave guides or coaxial cables can be used to guide lower-frequency electromagnetic radiation. Optical Fiber An optical fiber is usually circular in cross section and consists of a core and cladding. An optical fiber for communication applications is typically between about 0.1 and 0.2mm (0.004 and 0.008 in) in diameter. In order that the light waves be guided by the fibe ...

  • Fusion - 1,323 words
    ... eating, and the onset of nuclear fusion. The situation in star formation differs in one respect: after gravitational collapse ceases and star begins to expand again due to heat from exoergic nuclear fusion reactions, the expansion is arrested by the gravity force associated with the enormous mass of the star. In a star a state of equilibrium in both size and temperature is achieved. In ICF, by contrast, complete disassembly of fuel occurs. The fusion reaction least difficult to achieve combines a deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge ...

  • Is There Another Earth Out There - 1,049 words
    Is There Another Earth Out There? Is There Another Earth Out There? (adopted from an article by Guillermo Gonzalez, Donald Brownlee and Peter D. Ward, Refugees for Life in a Hostile Universe, Scientific American, October 2001) Is there life on other planets? Science has been trying to answer this question for a long time. In the article, the authors argue that it is highly improbable that complex life forms exist in our galaxy. To quote the authors: "Researchers are now casting a skeptical eye on musings about the prevalence of intelligent life throughout the Milky Way". Furthermore, according to the article, not only may most of the solar system be unfriendly to multi-cellular or complex or ...

  • Microwaves - 1,370 words
    Microwaves You might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally". But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same energy that warned the British of the German Luftwaffe invasion and that policemen employ to pinch speeding motorists, is what many of us now have in our kitchens. It's the same as what carries long distance phone ...

  • Motivation In A Bilingual Classroom - 1,440 words
    Motivation In A Bilingual Classroom Common Classroom Practices: A Psychological Approach Regarding Motivation in a Bilingual Classroom 2 Students want and need work that enables them to demonstrate and improve their sense of themselves as competent and successful human beings. This is the drive toward mastery. But success, while highly valued in our society, can be more or less motivational. People who are highly creative, for example, actually experience failure far more often than success. Biehler (p. 225) claims that studies show that when CAI used in conjunction with a teacher's lessons, is particularly beneficial for low-achieving and young students. Before we can use success to motivat ...

  • Neutrinos And Gamma Rays - 863 words
    Neutrinos and Gamma Rays Emission of a beta particle produces an energy change in the nucleus of an atom. The energy change that is observed, however, does not add up to satisfy the Law of Conservation of energy. The conservation law can be balanced if another particle, called the neutrino is part of this process. In the time it takes to read just this sentence, more than a billion of them will have passed unnoticed through the reader's body. Neutrinos may account for an appreciable portion of the mass of the universe, even tending to slow it's rate of expansion. Originally proposed in 1931 by Wolfgang Pauli to account for mass that was mysteriously lost from certain nuclear reactions,and fi ...

  • Observing Stars - 1,341 words
    Observing Stars Observing Stars Our 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 interact perpendicularly to each other, with different ranges of wavelength. The magnetic field oscillates vertically and the electric field horizontally, and each field induc ...
