71: Being a Substitute Teachers Aid
... will have discipline of program already in place. One of the teachers I worked with had one such program that did work in her class. Her system was a using a series a checks and stars when a child acted out. My job was to praise and sometimes reward good behavior so the other children would try and behave. If they got three checks they had to stay in at recess ... so I will notice them also. This definitely takes patience in a special education class. After all the children rotated from each activity table, I let the teacher know who got checks and who got stars. She used the stars as a positive reinforcement method once the children went back to their tables. The children also had group tables, and at the end of the week the group with the most stars got a ...
72: Fusion 2
... to form neutral particles, while photons are continuously being produced and absorbed. Scientists have estimated that more than 99 percent of the matter in the universe exists in the plasma state. All of the observed stars, including the Sun, consist of plasma, as do interstellar and interplanetary media and the outer atmospheres of the planets. Although most terrestrial matter exists in a solid, liquid or gaseous state, plasma is found in ... problem of producing and confining a hot, dense plasma. The core of a fusion reactor would consist of burning plasma. Fusion would occur between the nuclei, with electrons present only to maintain macroscopic charge neutrality. Stars, including the Sun, consist of plasma that generates energy by fusion reactions. In these natural fusion reactors the reacting, or burning, plasma is confirmed by its own gravity. It is not possible to assemble on ... German-born physicist Hans A. Bethe first recognized that the fusion of hydrogen nuclei to form deuterium is exoergic (there is release of energy) and, together with subsequent reactions, accounts for the energy source in stars. Work proceeded over the next two decades, motivated by the need to understand nuclear matter and forces, to learn more about the nuclear physics of stellar objects, and to develop thermonuclear weapons (the hydrogen ...
73: Creative Writing: The Visitor
Creative Writing: The Visitor The night sky of Neton was a clear one. The deep blue, almost a black but well illuminated by the bright full moon, glistened with a pattern of twinkling stars. The background light from Brisbane was almost nonexistent, a pleasant change of atmosphere that was rarely appreciated by most. Except Jane. She loved the clear sky, the faint presence of the Milky Way as it ... an inhabitant of this world who is worthy and give him/her a piece of technology that will give their Kind the means to break the confines of their Solar System and go to the stars. He has been watching the people of this planet for a long time so that he may choose a person to receive such a great gift. As he bounded off to the residence of the ... in the dark where no one will ever know or see. I have searched for many Earth years, for a person like You. You who will be the one to send your race to the stars," With that he thust a arm band into her arms. She examined the arm band. It was like the aliens but the Keys and the L.C.D screen were in English. Attached to ...
74: Origin Of The Solar System
... during the last three centuries can be classified as either dualistic or monistic. A common feature of dualistic theories is that another star once passed close to the Sun, and tidal perturbations between the two stars drew out filaments of gas from which the planets condensed. Theories of this type encounter enormous difficulties in trying to account for modern information about the solar system, and they have generally been discarded. By ... differences observed among the planets not only lead to a better understanding of the planets, but also pose precise new questions concerning the mechanisms by which the planets may have been formed. Studies of the stars within our galaxy have shown that the age of our galaxy is much greater than the age of the solar system. Therefore, processes observed in the formation of stars within our galaxy today are likely to be found relevant to the formation of our solar system. Stars appear to form in groups or associations, as a result of the gravitational collapse of clouds ...
75: The Black Hole
... Event Horizon until it has spun into the centre where it is concentrated within the core adding to the mass. Such spinning black holes are known as Kerr Black Holes. Most black holes orbit around stars due to the fact that they once were a star, and this may cause some problems for the neighboring stars. If a black hole gets powerful enough it may actually pull a star into it and disrupt the orbit of many other stars. The black hole could then grow even stronger (from the star's mass) as to possibly absorb another. When a black hole absorbs a star, the star is first pulled into the Ergosphere, which ...
76: GPS: The Future of Navigation and Technology
... set out hunting for food. The earliest mariners followed the coast closely to keep from getting lost. When navigators first sailed into the open ocean, they discovered they could chart their course by following the stars. The ancient Phoenicians used the North Star to journey from Egypt and Crete. According to Homer, the goddess Athena told Odysseus to "keep the Great Bear on his left" during his travels from Calypso's Island. Unfortunately for Odysseus and all the other mariners, the stars are only visible at night - and only on clear nights. The next major developments in the quest for the perfect method of navigation were the magnetic compass and the sextant. The needle of a compass always points north, so it is always possible to know in what direction you are going. The sextant uses adjustable mirrors to measure the exact angle of the stars, moon, and sun above the horizon. However, in the early days of its use, it was only possible to determine latitude, the location on the Earth measured north and south, from the sextant observations. ...
77: The Supernatural In King Lear
... was caused by the treacheries of the evil characters. Gloucester is a character in the play who firmly believed that man’s fate has supernatural properties that are controlled or reflected by the heaven and stars: These late eclipses in the sun and moon Portend us to no good. Though the wisdom of nature can reason it thus and thus, yet nature finds itself scourged by the sequent events. (Act 1 ... in the heavens. Gloucester believed that Lear’s actions also came as a result of the star’s unusual behaviour. Edmund, the treacherous and bastard son of Gloucester, exploits Gloucester’s blind believe in the stars in his plot to oust Edgar out of the inheritance and ultimately to gain all of Gloucester’s wealth and land: This is the excellent foppery of the world, that when we are sick in fortune (often the surfeits of the sun, the moon, and stars, as if we were villains on necessity; fools by heavenly compulsion; knaves, thieves, and treacherous by spherical predominance; drunkards, liars, and adulterers by an enforced obedience of planetary influence; and all that we are ...
78: Love Is Like...the Universe
... style. For instance, the universe holds within it a plethora of celestial bodies. Just like the cosmos, love branches off into many distinct feelings. The galaxy doesn't consist of planets alone; it contains asteroids, stars, and black holes. Similarly, love doesn't consist of just an intimate affection towards one s parents, but also involves feeling a deep passion for a friend or even an object. Also, the formation itself ... start looking at the entire picture. In addition, in the galaxy, the constellation s positions and appearance change as time goes by, and just like the cosmos, love changes as well. For example, while old stars die, new stars are created. This is like losing the "old feelings" a person used to have. Yet at the same time, new affection develops. Furthermore, changes in the galaxy are very subtle; in the identical fashion, ...
79: Into the Depths of A Black Hole

Most black holes orbit around stars due to the fact that they once were a star, and this may cause some problems for the neighboring stars.

80: Masters Of The Universe
... gravitational field(Intro. to Black Holes 1). This is why a black hole is a black hole. No light can escape from it, therefore, we cannot see it. A binary star system consists of two stars that orbit around each other. They were discovered by Yakov Zeldovitch(Filkin 224). Sometimes, one star in a binary star system will die and become a black hole. When this happens, the force of the ... a black hole(Filkin 224). Second, view X-rays that are given off by the black hole through the use of radio telescopes(Filkin 225). In a galaxy without a black hole at the center, stars closer to the center would move slower than those on the outside(Olson 51). On the other hand, if the galaxy is indeed powered by a black hole, the force of the black hole will make the stars near the center move the fastest(Olson 51). The object in the center of the Milky Way Galaxy is named, Sgr A*(Freedman 69). The stars in our galaxy that are closest to Sgr ...
