Soil Erosion Human Actions
1,131 wordsSoil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. Soil deterioration and low quality of water due to erosion and run off has often become a severe problem around the world. Many times the problems become so severe that the land can no longer be cultivated and is abandoned. The key to minimizing soil erosion and saving the farm lands is the farmer himself. Ultim...

In the USA, soil has recently been eroded at about 17 times the rate at which it forms: about 90 % of US cropland is currently losing soil above the sustainable rate. Soil erosion rates in Asia, Africa and South America are estimated to be about twice as high as in the USA. FAO estimates that 140 million ha of high quality soil, mostly in Africa and Asia...

Hubble Space Telescope Universe Continues To Expand Energy
786 wordsThe universe begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. The prevailing theory describes a peculiar form of energy that can suddenly push out the fabric of space. On a rare occasion, a runaway process called "Inflation" can cause a vast expansion of space filled with this energy. The inflationary expansion is stopped o...

Food Chain Laser Light
895 wordsLIGHT: A FUNDAMENTAL FORCE IN OUR WORLD If asked what light is, one could say that it's one of the most basic elements of our world and our universe as we perceive it. It is through sight that we receive 90 % of our information. It is through the use of telescopes aiding the naked eye that we are aware of the heavenly bodies around us. It is through light that the energy from the sun is transferred to us. The sun's energy supports the food chain; plants use it to turn water and CO 2 into energy ...

Law Of Motion Universal Gravitation
729 wordsMediaeval understanding of science had mostly based Aristotle; Aristotle's ideas held for thousands of years until the scientific revolution begin breaking them off. It is Newton helped the transformation of natural philosophy into modern science. Newton established the science of mechanics and laid the groundwork for classical physics with law of motion he discovered. These principles might seem obvious and simple to todays physicists, but this was a new way of thinking in Newtons time. Instead...

Positive And Negative Conduct Electricity
595 wordsElectrolytes are liquids that conduct electricity. Most need to be dissolved into water or another solvent. Battery's have an electrolyte in them, either as a liquid or as a paste. Liquid electrolytes are used in electrolysis, electroplating, and other chemical processes. When electrolytes dissolve they release positive and negative ions. The released ions carry electric charges between electrodes, in the solution. Cations (a positively charged ion that migrates to the cathode, a negative electr...

Contingent Beings Infinite Series

The main disagreement about the causal argument centers on the infinite series paradox. Aquinas states that to imply an infinite series is not only illogical, it also implies that nothing exists. Yet we know that things do exist, hence the infinite series is wrong. Let me explain a little better, Aquinas reasoned that whenever we take away the cause the effect ...

Stephen Hawking A Life In Science
1,791 wordsdepicts the life and accomplishments of Stephen Hawking, a unique and towering figure in modern physics, perhaps the most famous scientist since Einstein. He has achieved far more than the vast majority of able-bodied people would ever have dreamt of accomplishing. He has made fundamental breakthroughs in cosmology and, perhaps more than anyone else alive, he has pushed forward our understanding of the universe we live in. His brilliant work on black holes, the big bang, and quantum cosmology ha...

In a famous passage (II, XI, 17), Locke compares the mind to a "dark room" (in the Latin, "camera obscura") with only a narrow inlet. Ideas are analogous to the images projected onto the back of the room. Locke classified the various simple ideas according to the following scheme. Those that come to the mind by one sense only, such as color or odor. Those that come in to the mind by...

Acid Rain Sulfur Dioxide
566 words"Acid rain" is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. Wet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depend on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees,...

Some three thousand stars can be seen with the naked eye, twinkling points of light that have inspired the human spirit since the dawn of time. Study of the stars, based on data collected from visible-light telescopes, radio telescopes, and detectors wavelengths can now reveal extraordinary amounts of information: size, temperature, chemical composition, internal structure, distance and rotation rate, among other factors. One of the most...

U S Military Global Positioning System
1,395 wordsIn the 1800 s, most things were done using manpower, not machines. To plow a field it used to require a team of horses and a plow. To make butter it required a hand churn. Life was simple and people depended on themselves. In the 1920 s the automobile was a very important technological machine. Instead of a team of horses and a carriage, one could move about more efficiently in an automobile. Through the following years many advances in technology occurred: electric machines, televisions, radios...

Flu Virus Percent Effective
812 wordsFor 3 decades, scientists have been experimenting with medications that stifle the influenza virus. Two drugs, amantadine and rimantadine, can impede the disease and limit symptoms. However, neither works against one of the two major strains of influenza, and both can be eluded by the evolving virus. In addition, amantadine causes some disagreeable side effects, including confusion and nightmares. A new antiviral zanamivir seems to ease or eliminate many symptoms of either flu strain if taken wi...

The term photoelectric effect designates several types of interactions. In the external photoelectric effect, electrons are liberated from the surface of a metallic conductor by absorbing energy from light shining on the metals surface. This is the form that we g...
