Physics Jokes

At a Physics course at a University, many years ago, the professor thought to give his students the following assignment to answer: 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 when it expands and heats 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 at which souls are moving into Hell and the rate at which 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, let's look at the different Religions that exist in the world today. Most of these religions state that if you are not a member of their religion, you will go to Hell. Since there is more than one of these religions and since people do not belong to more than one religion, we can project that 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 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: 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. 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 go out with you", and take into account the fact that I went out with her last night, then number 2 must be true, and thus I am sure that Hell is exothermic and has already frozen over. The corollary of this theory is that since Hell has frozen over, it follows that it is not accepting any more souls and is therefore, extinct . . . leaving only Heaven, thereby proving the existence of a divine being which explains why, last night, Teresa kept shouting "Oh my God." THIS STUDENT RECEIVED THE ONLY "A+"

A Physics professor had a student that was always late and always had an answer or an excuse. He decides to ask him a few questions in front of the class and put him on the spot. "Tell me, Michael, What is faster, light or sound?" "Well light, obviously." "Alright, why?" "Well, when I turn on my TV, I first see the picture and then comes the sound" The professor sighs and gives a you're-an-idiot look. He moves to the next student asks the same question. "What is faster, light or sound?" "Well obviously it is sound." "Uhhh what?? Why do you think this?" "Well when I turn on my TV, I first hear it and then comes the picture." Extremely annoyed the professor is now a bit pissed off. He believes that maybe the question is too hard for these pea brains and tries to vary it. The next student he asks "You are on the foot of a mountain. On the summit there is a cannon being fired. Do you first see the light of the fire or do you first hear the sound?" "Obviously you first see the light." Slightly hopeful the professor says "YES and why is that?" "Well the eyes are obviously further ahead than the ears."
