A true story. A thermodynamics professor had written a take home exam for his graduate students. It had one question: Is hell exothermic or endothermic? Support your answer with a proof. Most of the students wrote proofs of their beliefs using Boyle's Law or some variant. One student, however wrote the following: First, we postulate that if souls exist, then they must have some mass. If they do, then a mole of souls can also have a mass. So, at what rate are souls moving into hell and at what rate are souls leaving? I think that we can safely assume that once a soul gets to hell, it will not leave. Therefore, no souls are leaving. As for souls entering hell, lets look at the different religions that exist in the world today. Some of these religions state that if you are not a member of their religion, you will go to hell. Since there are more than one of these religions and people do not belong to more than one religion, we can project that all people and all souls go to hell. With birth and death rates as they are, we can expect the number of souls in hell to increase exponentially. Now, we look at the rate of change in volume in hell. Boyle's Law states that in order for the temperature and pressure in hell to stay the same, the ratio of the mass of souls and volume needs to stay constant. So, if hell is expanding at a slower rate than the rate at which souls enter hell, then the temperature and pressure in hell will increase until all hell breaks loose. Of course, if hell is expanding at a rate faster than the increase of souls in hell, than the temperature and pressure will drop until hell freezes over. So which is it? If we accept the postulate given me by Therese Banyan during Freshman year concerning cold days in hell, and take into account the fact that I still have not succeeded in having sexual relations with her, then the second cannot be true, and hell is thus proved to be exothermic."
reminds me of that other story about an essay where the philosophy professor makes an essay prompt that asks merely "why?" and the guy who replied "why not?" got the best grade.
A group of students were out partying for the weekend. They lost track of time and missed an important test on monday at college. When they finally went back on tuesday, one of the guys went up to the proffessor and told him that they got a flat tyre on the way back and that's why they were late. The proffessor then let them take the test in separate rooms. The test was as following: Question 1 (5%): What is your name? Then they turned the page. Question 2 (95%): Which tyre?
