A physicist, biologist, and a chemist were going to the ocean for the first time. The physicist saw the ocean and was fascinated by the waves. He said he wanted to do some research on the fluid dynamics of the waves and walked into the ocean. Obviously, he drowned and never returned. The biologist said he wanted to do research on the flora and fauna inside the ocean and walked into the ocean. He too never returned. The chemist waited for a long time and afterward, wrote the observation, "The physicist and the biologist are soluble in ocean water."
