Deep sea diving is generally performed with the aid of a breathing apparatus. SCUBA (an acronym for Self-Contained Underwater Breathing Apparatus) is a system that delivers air to the diver at the same pressure exerted by the surrounding water. Most scuba divers limit their descent to about 130 ft (40 m), though certain record setters have reached depths of 300 ft (91 m) or more. At depths beyond 130 ft, nitrogen narcosis may set in; how does this condition impair a diver's judgment?

It is believed that the original potato chip recipe was created by Native American chef George Crum at the Moon Lake Lodge in Saratoga Springs, NY, on August 24, 1853. Fed up with a customer who continued to send his fried potatoes back, claiming they were too thick and soggy, Crum decided to slice the potatoes so thinly that they couldn't be eaten with a fork. The customer was delighted, and the chips became a regular item on the lodge's menu. According to some accounts, who was the customer?

Kahanamoku, known as the "Big Kahuna," was an Olympic champion swimmer who is generally credited with having invented the modern sport of surfing.
