Archeologists have toiled for years trying to piece together the puzzle of past civilizations. Archeology, however, can be classified as a form of glorified grave robbing, rather than a way to recreate and understand the ways of past societies. While the artifacts uncovered can be helpful in painting a picture of what the lives of past...

It happens to about 1% of the population, both equally in men and women. When the person is going through a manic episode they have lots of energy, talk fast, jumping from topic to topic.

In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a s...
The Greenhouse Effect and Global Warming Recently, global warming has moved to a serious scientific issue. Because sunlight is constantly falling on the earth, the law of physics say that the planet has to radiate the same amount of energy back into space. Infrared radiation is sent out by the earth through the atmosphere, where molecul...
The aging process is difficult to analyze because of the way that the body's organ systems work together. The breakdown of one structure will ultimately affect the function of others. The medical field of gerontology deals with examining the biological changes of aging, both passive and active, that occur at the molecular and cellular levels....
Toss a pebble in a pond -see the ripples? Now drop two pebbles close together. Look at what happens when the two sets of waves combine -you get a new wave! When a crest and a trough meet, they cancel out and the water goes flat. When two crests meet, they produce one, bigger crest. When two troughs co...
Are Anabolic Steroids Safe Even if you didn't have any or little knowledge of steroids and were asked this question, you would probably answer no. Why? Would it be because a high school kid somewhere in California died from taking them? Or would it be because you read it in Readers Digest? Many people think you are selling your soul to t...
Ensuring Our Future Through Conservation The world's natural rainforests are one of humanity's only remaining hopes to continue its existence. Rainforests are vast forests filled with lush vegetation, teeming with life (both animal and plant), of which only about 40 percent has been completely discovered and studied. Rainforests are a b...
Global warming--is it getting warmer Greenhouse Effect: Is it Getting Warmer? By definition, the greenhouse effect is a term for the role the atmosphere plays in insulating and warming the earth's surface. In modern society, this is the term for something better known as global warming. The earth?s climate is predicted to change drastica...
There are three principal kinds of carbohydrates and each are classified according to the number of sugar molecules they contain. Monosaccharides, such as ribose, glucose, and fructose, contain only one sugar molecule. Disaccharides consist of two sugar molecules linked covalently. Familiar examples are sucrose (table sugar), maltose (malt suga...
THE PRIORITY OF HEPATITIS B VACCINATIONS IN CANADA The increase in the number of children attending schools in Canada and the potential for transmission of viral infection in that environment is a problem of great size. A virus is defined as "a morbid principle, or a poisonous venom, especially one capable of being introduced into anothe...
Comparison of the evolution theories of Charles Darwin and Jean-Baptiste Lamarck In this essay I am going to compare the theories of Charles Darwin and Jean-Baptiste Lamarck. Charles Darwin was a British Scientist who lived between 1809-1882. He laid down the foundation of modern evolutionary theory with his concept of the developmen...
Laser is an acronym for light amplification by stimulated emission of radiation. In the last century many types of lasers have been used for many different applications from welding to surgery to military and even many uses in every day life by harnessing the principles of light and stimulated emission. To understand how lasers work we m...
Basically this section that I read told about different types of microphones, what they can do and what they can not do. It told us that microphones were contained metal diaphragms that vibrate when the sound waves hit them, the vibrations are converted into electric impulses by back plates or coils. The impulses can be amplified, and r...
