New Submarine Ensign

The new Ensign was assigned to subs, where he'd dreamed of working since a young boy.
He was trying to impress the Master Chief with his expertise learned in Submarine School.
The Master Chief cut him off quickly and said, "Listen, 'sir', it's real simple. Add the number of times we dive to the number of times we surface. Divide that number by two. If the result doesn't come out even, don't open the hatch."

Melvin Calvin

Born 8 Apr 1911; died 8 Jan 1997 at age 85.Melvin Ellis Calvin was an American biochemist who was awarded the 1961 Nobel Prize in Chemistry for furthering our knowledge of the mechanism of photosynthesis. In the Calvin Cycle, he described the “dark reactions” of photosynthesis occuring in green plants through the night turning carbon dioxide into sugar. Using carbon-14 isotope as a tracer in carbon dioxide, Calvin and his team identified the complete route as the carbon atom travels through a plant during photosynthesis, from the absorption of atmospheric carbon dioxide to its incorporation into carbohydrates and other organic compounds. With his group, Calvin showed that the sunlight acts on the chlorophyll molecules in a plant, and not on the carbon dioxide (as had been previously believed).«
