.... the thought still remains in today's societies. “For we of the 20th century still treat the ocean as the endless, bottomless pit it was considered to be in medieval times.”(Heyerdahl) The majority of the world's population still lives under the misconception that the ocean is a hungry abyss, eager to devour all their waste. These beliefs, however, are all untrue. The average depth of the oceans is only a little more than a mile, when in fact, some lakes exceed this depth rather handily. Although the size of the ocean is often pondered, the thought that i .....

.... brilliant man of his own time. He made contributions to science, mathematics, and religious philosophy. Pascal was born on June 19, 1623 in Clermont-Ferrand of central France. His father was a highly placed civil official and everyone expected Pascal to follow in his footsteps. But Pascal proved to be a child prodigy. At the age of twelve, he figured out the proposition of Euclidean geometry with no help. At the age of seventeen, he wrote an essay on conic sections which contained a theorum that was named after him. Pascal also invented many things. He constructed the first digital calculating syste .....

.... a popular star in the NFL, developed a brain tumor and died. Also one of the greatest bodybuilders of all time and famous actor, Arnold Schwarzenegger, had to have an operation to repair an aortic valve in his heart. This scared a lot of people and the recreational uses of steroids decreased. With the dangers of steroids well-known people started looking for other substances to give them an edge. Bee pollen, carnitine and chromium picolinate, were among the things people tried. Of course none of these worked. But now there is a product on the market that ha .....

.... distributed throughout the world, particularly in the temperate and tropical regions where there is sufficient moisture for them to grow. They are less likely to be found in dry areas. Some few types of fungi have been reported in Arctic and Antarctic areas (some molds, after all, thrive on refrigerated food). There are about 50,000 known species of . Although any single typical may not be uniform in appearance--a mushroom, for example, has a cap, stem, and rootlike components--it has, in fact, a uniform structure throughout. The typical consists of a mass .....

.... of chemicals that cause . Power stations emit large amounts of sulfur dioxide and also nitrogen oxides, while car exhaust contains large amounts of nitrogen oxides. Once is formed, it can stay up in the clouds for a long time. These clouds can be carried off by the wind to other areas, sometimes hundreds of miles away, where they eventually fall to the Earth as or snow. This is called transboundary pollution. For awhile some people believed that by building high smoke stacks they would be sending the chemicals out of harms way. But all this did was pu .....

.... the mid-1700s, human activities began to alter the composition of the atmosphere. Vast supplies of charcoal, and later coal and oil, fed the growing fires of the Industrial Revolution. The carbon stored in these fuels was released to the air as carbon dioxide - a gas that traps heat in the atmosphere. Today, for every one of the more than 5.8 billion people on Earth, nearly six tons of carbon dioxide is spewed into the air every year. As a result of our activities, the gas trapped inside the atmosphere has risen by more than 30 percent in the last 250 years. Th .....

.... of the most obvious symptoms. (7) Chickenpox mostly occurs in children classifying it as a childhood disease although it can occur in adults who are not yet immune to it. This could lead to the belief of chickenpox being one of the oldest diseases. Since the chickenpox infection has two phases, one most common during childhood then a latent form that can become active again later in the persons life, doctors believe that this reactivation would start the cycle all over again. If everyone in the first cycle got the germ then became immune a whole new generat .....
