.... Doctors are now able to use lasers for surgery. Lasers are based on the physical principle of light, and are devices for the creation and amplification of a narrow, intense beam of coherent light. New laser microsurgery can actually alter the shape of the cornea in the eye so the patient's eyesight can return to normal, and he/she will no longer need those bothersome glasses. Ultrasound is used in the medical field for destroying various unwanted substances in the body such as kidney stones. Ultrasound uses sound waves to dissolve these foreign bodies. If not for physics, ultrasounds wo .....

.... the discrepancy between what we want from academic institutions and what we get from current institutions, a market-based alternative called "idea futures" is suggested. It is described through both a set of specific scenarios and a set of detailed procedures. Over thirty possible problems and objections are examined in detail. Finally, a development strategy is outlined and the possible advantages are summarized. THE PROBLEM THE SCIENTIFIC REVOLUTION Four centuries ago, some Europeans complained that the existing academic institutions were biased against them. Insiders, it was said, .....

.... an opinion on whether steroids are safe are not, it would help to know how they work and what responsibilities are needed when choosing to take them. are a synthetic for of the naturally occurring hormone, testosterone. are used to promote accelerated muscle hypertrophy in both males and females. Hypertrophy describes the increase in size of muscle as the result of stress put upon the muscle. Muscles go through hypertrophy in order to adapt to the increased demands placed upon them to perform. This is the primary goal of weight training. Once steroids are introduced into the blood .....

.... badly scratched or removed. A physician is not usually not needed to make a diagnosis but after the symptoms appear it is still best to make sure it is the chicken pox and not something much worse. The physician can easily make a diagnosis by checking the basic symptoms. Chicken pox is controlled by keeping the infected person and anything the infected person has come in contact with away from any people who have never become infected. There is not really a treatment, just medicine so that the rash does not itch. The disease blows over by itself.The disease cannot really be pre .....

.... The first, translocation, takes place when a child inherits an extra piece of chromosome 21 attached to a different chromosome. The second, called mosaic Down syndrome, results when only some cells in the body have the extra chromosome. There is no cure for Down syndrome although prenatal tests are available to identify fetuses with the disorder. Down syndrome can be diagnosed just by looking at the baby at birth. The facial features and characteristics can tell you that. If the attending physician suspects Down syndrome, a karyotype – a blood or tissue sample stained to show chromosomes .....

.... dance eventually gets so extreme that a young man in the crowd snaps his neck and dies. The man does not stop his ravings and the crowd doesn't stop their dance. Instead the man becomes entirely deranged, screaming at the body of the young man that he is now going to hell where he rot in flames of agony for eternity. The crowd roars and the man laughs. What do you suppose would now transpire? At the very least the man and the crowd would be arrested. More than likely there would be several charges of third degree murder laid, certainly with several convictions. The preacher would most .....

.... and provide links to our past. People have lived in North America for at least 12,000 years. Archaeologists and historians have divided this time span into prehistoric and historic periods. The prehistoric period extends from the earliest arrival of humans in North America to the coming of the European explorers. The historic period begins with the arrival of these explorers and continues up to the present. As you walk across public land, something on the ground catches your eye. You pick up a piece of pottery or an arrowhead, wondering about the people who made this artifa .....

.... that much of it's territory is located within the northern pole a lot of the Tundra receives alternating 6 month periods of light and dark. This is also the reason why the Tundra receives cold weather; at it's degree of latitude the suns rays end up hitting the region obliquely, thus causing less solar heat. Here are the temperatures of the Tundra in general: Average January temperature: -32.1 degrees Celsius Average July temperature: +4.1 degrees Celsius Temperature range: 36.2 degrees Celsius Average annual temperature: -17 degrees Celsius Lowest temperature recorded: -52.5 degrees .....

.... melting points, but most liquids can remain liquid even though cooled below their freezing points. A liquid may remain in this supercooled state for some time. This phenomenon is explained by molecular theory, which conceives the molecules of a solid as being well ordered and the molecules of a liquid as being disordered. To solidify, a liquid must have a nucleus (a point of molecular orderliness) around which the disordered molecules can crystallize. The formation of a nucleus is a matter of chance, but once a nucleus forms, the supercooled liquid will solidify rapidly. The freezing poin .....
