To contribute to the exam humor that's shown up here recently.... (This is true, told to me by a chemistry professor at Idaho State University.) The professor had the following as an extra credit question on an exam: An age-old question is ``How many angels can dance on the head of a pin?'' Answer that question given the following: Each angel requires an area equal to a circle with a diameter the size of a gold atom in which to dance. The pin in question has a head which is a circular plane with a diameter of 0.5 mm. Make any other assumptions necessary to solve the problem. The professor was sorry to admit that he had to give full credit to the following answer: I assume that angels do not exist. The answer is 0. -- Geoff Allen uunet!pmafire!geoff geoff@pmafire.inel.gov
