The answer by one student was so "profound" that the professor shared it with colleagues, via the Internet, which is, of course, why we now have the pleasure of enjoying it as well. Bonus Question: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)? Most of the students wrote proofs of their beliefs using Boyle's Law, (gas cools off when it expands and heats up when it is compressed) or some variant. One student, however, wrote the following: "First, we need to know how the mass of Hell is changing in time. So we need to know the rate that souls are moving into Hell and the rate they are 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 how many souls are 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 since people do not belong to more than one religion, we can project that most 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 of the volume in Hell because Boyle's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand proportionately as souls are added. This gives two possibilities: 1. 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. 2. If Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over. So which is it? If we accept the postulate given to me by Teresa during my Freshman year, "...that it will be a cold day in Hell before I sleep with you," and take into account the fact that I still have not succeeded in having that event take place, then, #2 cannot be true, and thus I am sure that Hell is exothermic and will not freeze." The student received the only "A" given. +++++++++++++++++++++++++++++++++++ Rules of the air. 1. Every takeoff is optional. Every landing is mandatory. 2. If you push the stick forward, the houses get bigger. If you pull the stick back, they get smaller. That is, unless you keep pulling the stick all the way back, then they get bigger again. 3. Flying isn't dangerous. Crashing is what's dangerous. 4. It's always better to be down here wishing you were up there than up there wishing you were down here. 5. The ONLY time you have too much fuel is when you're on fire. 6. The propeller is just a big fan in front of the plane used to keep the pilot cool. When it stops, you can actually watch the pilot start sweating. 7. When in doubt, hold on to your altitude. No one has ever collided with the sky. 8. A 'good' landing is one from which you can walk away. A 'great' landing is one after which they can use the plane again. 9. Learn from the mistakes of others. You won't live long enough to make all of them yourself. 10. You know you've landed with the wheels up if it takes full power to taxi to the ramp. 11. The probability of survival is inversely proportional to the angle of arrival. Large angle of arrival, small probability of survival and vice versa. 12. Never let an aircraft take you somewhere your brain didn't get to five minutes earlier. 3. Stay out of clouds. The silver lining everyone keeps talking about might be another aeroplane going in the opposite direction. Reliable sources also report that mountains have been known to hide out in clouds. 14. Always try to keep the number of landings you make equal to the number of take offs you've made. 15. There are three simple rules for making a smooth landing. Unfortunately no one knows what they are. 16. You start with a bag full of luck and an empty bag of experience. The trick is to fill the bag of experience before you empty the bag of luck. 17. Helicopters can't fly; they're just so ugly the earth repels them. 18. If all you can see out of the window is ground that's going round and round and all you can hear is commotion coming from the passenger compartment, things are not at all as they should be. 19. In the ongoing battle between objects made of aluminum going hundreds of miles per hour and the ground going zero miles per hour, the ground has yet to lose. 20. Good judgment comes from experience. Unfortunately, the experience usually comes from bad judgment. 21. It's always a good idea to keep the pointy end going forward as much as possible. 22. Keep looking around. There's always something you've missed. 23. Remember, gravity is not just a good idea. It's the law. And it's not subject to repeal. 24. The three most useless things to a pilot are the altitude above you, runway behind you, and a tenth of a second ago. . ________________________________________________________________ Sign Up for Juno Platinum Internet Access Today Only $9.95 per month!
