MATH PUZZLE: Can you replace the question mark with a number?
MATH PUZZLE: Can you replace the question mark with a number?
There was a shipwreck at sea and Doug, Steve, and Phil got washed ashore on a small, isolated island. They were exhausted and fell asleep on the beach. Doug woke up and saw a box of bananas had washed ashore. He ate 1/3 of bananas and went back to sleep. Steve woke up and also ate 1/3 of what was left of the bananas, and went back to sleep. Next, Phil woke up and assuming no one had eaten the bananas, ate only 1/3 of what was left. When he was finished, there were only 8 bananas left. Can you guess how many bananas were in the box?

Charles Gerhardt

Born 21 Aug 1816; died 19 Aug 1856 at age 39. Charles (-Frédéric) Gerhardt was a French chemist who, with Auguste Laurent, developed a classification of organic compounds. Like most chemists he was aware that the dualistic system of Jöns Berzelius was unsatisfactory and tried to create an alternative. He adopted what became known as type theory in which he thought all organic compounds were based on four main types - hydrogen, hydrogen chloride, ammonia, and water. Organic compounds were referred to these types by replacing a hydrogen atom in one of these compounds by a radical (i.e., by a group of atoms). His idea was opposed by his contemporaries and was later abandoned, but it proved important in the subsequent rationalization of structural organic chemistry.
