The Underwater World"There you are, weightless, hovering quietly just above the seabed with only minimal physical effort. Small fish emerge from their holes to look at you. How about it? You are the thing that has no place. Perhaps that is why you are participating in the exploration of man's last ecological frontier. The thought alone would excite anyone who still has blood in his veins. The diver is the observer, he watches everything he can. He totally forgets the outside world. When I first read this article, 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 seems 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 discusses the development and use, techniques, and physiological concerns of scuba diving. Man underwater dates back to the Iliad, but sport diving for pleasure and for work is relatively new. If anyone has ever been underwater, they must know that breathing is impossible. In the early 1940s, Jacques Yves-Cousteau, a Frenchman, developed something that is today a very important asset to scuba diving. We call it a “regulator”. The regulator conserved air by releasing only the amount of air the Korell 2 diver needed to breathe. This increased the length of time the diver could stay on an air tank to about an hour if at shallow depths. Cousteau's regulator was simple and inexpensive and marked the beginning of the sport of scuba diving. The sport has become a bit slow...... middle of paper ...... very complex subject due to its scientific side. There are many scientific laws and 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 a lot more about scuba diving in Korell 9 than just the underwater part, then by all means go for it. After all, it's a completely different world out there.Bibliography:Counsilman and Drinkwater Bibliography. Beginner Skin and Scuba Diving. Belmont, CA: Wadsworth Publishing Company, Inc. 1964.
