The Underwater World"Here you are, totally weightless, silently rising just above the seabed with only the slightest physical effort. Small fish come out of their holes to look at you. Like this purpose? You are curiosity, you are the thing that doesn't belong. Maybe that's why you dive, you are participating in the exploration of man's last ecological frontier. The diver is the observer, he looks at everything he can and forgets. the outside world entirely" (Reseck 4). When I first read this piece I got goosebumps. For years man has explored this vast universe, spending millions of dollars, and making only a tiny scratch on its surface. For me, being able to explore a world completely different from my own feels like the opportunity of a lifetime. When I had to choose a topic for my senior project, scuba diving was the most compelling of all. This article is about the development and use, techniques and physiological aspects of scuba diving. Man underwater dates back to the Iliad, but sport diving for fun and as a profession is quite new. Anyone who has ever been underwater should know that breathing is impossible. In the early 1940s, Jaques Yves-Cousteau, a Frenchman, developed something that is now a very important asset to scuba diving. It is known to us as the "regulator". The regulator conserved air while releasing only the amount of air needed for the Korell 2 diver to breathe. This increased the time the diver could stay on an air tank to about an hour if he was at shallow depths. Cousteau's regulator was simple and cheap and marked the beginning of the sport of scuba diving. Sports has grown a bit slowly... middle of the paper... a very complex topic due to its scientific side. There are many scientific laws and many restrictions related to them. The only downside to learning to scuba dive is the cost. But if you're willing to spend around $450 and want to learn Korell 9 a lot more about scuba diving than the underwater part, then by all means go ahead. After all, it's a completely different world over there. Bibliography: Counsilman and Drinkwater Bibliography. Home Skin and Scuba Diving. Belmont, CA: Wadsworth Publishing Company, Inc. 1964.
