Changing World
Number of words: 1035 - Number of pages: 4

.... As a result, acid rain falls upon the earth destroying what is left of the planet's forests and, an estimated 37 percent of the fish species that inhabit thelakes and streams of North America are either in jeopardy or extinct. A second indicator that displays humanity's misuse of technoscience is the global economy. Global economic statistics show the results of the applications of technoscience. In 1995, the global economy grew by an estimated 3.7 percent the largest gain since the 4.6 percent growth in 1980 (Brown, 74). The use of technoscientific developments in various fields raised th .....

Effects Of Dam Building
Number of words: 1220 - Number of pages: 5

.... as either storage, diversion or detention. As you could probably notice from it's name, storage dams are created to collect or hold water for periods of time when there is a surplus supply. The water is then used when there is a lack of supply. For example many small dams impound water in the spring, for use in the summer dry months. Storage dams also supply a water supply, or an improved habitat for fish and wildlife; they may store water for hydroelectricity as well. A diversion dam is a generation of a commonly constructed dam which is built to provide sufficient water pressure for .....

Anti-Matter
Number of words: 1209 - Number of pages: 5

.... that react so destructively, and their arrangement makes no difference. Scientists at CERN in Geneva are working on a device called the LEAR (low energy anti-proton ring) in an attempt to slow the velocity of the anti-protons to a billionth of their normal speeds. The slowing of the anti-protons and positrons, which normally travel at a velocity of that near the speed of light, is neccesary so that they have a chance of meeting and combining into anti-hydrogen. The problems with research in the field of anti-matter is that when the anti-matter elements touch matter elements they .....

Cold Fusion
Number of words: 954 - Number of pages: 4

.... of the reaction is not completely understood. Some claim it is merely a chemical reaction not yet understood, while others are convinced it is a nuclear reaction. One example is a cell which used .04 grams of metal hydride. It produced 86 megajoules over a two month period. A similar chemical reaction would have required 2,000 grams of chemicals to produce the same amount of energy. Another interesting point regarding this cell was the fact it had to be deliberately shut down. There was no sign of the reaction tapering off. The skepticism regarding stems from two separate s .....

El Nino
Number of words: 380 - Number of pages: 2

.... effects on the worlds fishing industry. The cutting of nutrient rich therocline water reduces the growth of algae, which in trun, collapses the food chain. Thus, leaving our worlds subsistence and commercial fishermen with out food and money. With the already descendeing food chain on our earth, the warming water also effects the atmosphere, resulting in more extreme temperatures, more rain, and more drought periods, costing more money to our already debted economy, and the world. An example (demonstrated here by alaska) brought about by the extreme temperatures was during the 1976-77 .....

Digital Television
Number of words: 808 - Number of pages: 3

.... which means a broadcaster can mix multiple programs of varying bit sizes onto a single channel. Say you’re watching a football game, since one camera view only uses up so many bits, you can select a different camera angle while watching the same game on the same channel. It is possible for a network, like NBC, to show two different programs at the same time on the same channel. Conceivably, if the president in on, you can watch regular scheduled programming. With the introduction of the digital TV, the introduction of WebTV is upon us. One will be able to surf the internet through .....

Future Psychology
Number of words: 1638 - Number of pages: 6

.... is to stumble backwards into the future. We feel that we as individuals make little difference, as if history and the future just happen at us. Obscure plans, which have guided people forward in the past, have now rendered themselves useless. There are no known maps to show pathways into the future. We’ll need to consider back to our hearts, common sense and basic human capabilities. We’ll need to consider the deep issues at stake and make deep choices about them. This idea of disaster is actually an aide. It activates resourceful survival instincts. The human race needs to cha .....

Genetic Engineering
Number of words: 1118 - Number of pages: 5

.... was regulated to prevent such things the new science could bring wonders to many peoples lives. The first form of began with a man named Mendel, a monk in the late nineteenth century. He was the first to even formulate the concept of the gene from his experiments on pea plants. Since Mendel, other scientists have continued in agricultural engineering, a type of engineering that deals with the cross breeding of plants and cattle to maximize their productivity. Through time geneticists have continued to find better methods and strategies for improving the quantity of food from plants and .....

Black Holes
Number of words: 3099 - Number of pages: 12

.... which any matter or energy is doomed to disappear from the visible universe? The black hole's surface is known as the event horizon. Behind this horizon, the inward pull of gravity is overwhelming and no information about the black hole's interior can escape to the outer universe. Applying the Einstein Field Equations to collapsing stars, Kurt Schwarzschild discovered the critical radius for a given mass at which matter would collapse into an infinitely dense state known as a singularity. At the center of the black hole lies the singularity, where matter is crushed to infinite density, .....

Mitosis
Number of words: 239 - Number of pages: 1

.... ready for to take place. The chromatis is coiled up and consists of loose threads. In prophase, the next longest stage, the chromatin becomes chromatids which later form chromosomes. They are attached to the centrioles by spindle fibers. The chromosomes are lined up in the center of the celll. The nucleolus and nuclear membrane disappear. In the next phase, metaphase, the chromosomes line up along the metaphase plate. The plate is the midpoint of the cell between the two centrioles which are located at opposite poles. During anaphase, the centrioles start playing tug of war with the chromos .....
