Black holes are where God divided by zero.
Three men, a philosopher, a mathematician and an idiot, were out riding in the car when it crashed into a tree. Before anyone knows it, the three men found themselves standing before the pearly gates of Heaven, where St. Peter and the Devil were standing nearby. "Gentlemen," the Devil started, "Due to the fact that Heaven is now overcrowded, St. Peter has agreed to limit the number of people entering Heaven. If anyone of you can ask me a question which I don't know or cannot answer, then you're worthy enough to go to Heaven; if not, then you'll come with me to Hell." The philosopher then stepped up, "OK, give me the most comprehensive report on Socrates' Socrates' teachings." With a snap of his finger, a stack of paper appeared next to the Devil. The philosopher read it and concluded it was correct. "Then, go to Hell!" With another snap of his finger, the philsopher disappeared. The mathematician then asked,"Give me the most complicated formula ever theorized!" With a snap of his finger, another stack of paper appeared next to the Devil. The mathematician read it and reluctantly agreed it was correct. "Then, go to Hell!" With another snap of his finger, the mathematician disappeared too. The idiot then stepped forward and said, "Bring me a chair!" The Devil brought forward a chair. "Drill 7 holes on the seat." The Devil did just that. The idiot then sat on the chair and let out a very loud fart. Standing up, he asked, "Which hole did my fart come out from?" The Devil inspected the seat and said,"The third hole from the right." "Wrong," said the idiot, "it's from my asshole." And the idiot went to heaven.
The optimist sees the glass half full. The pessimist sees the glass half empty. The chemist see the glass completely full, half in the liquid state and half in the vapor state.
Three professors (a physicist, a chemist, and a statistician) are called in to see their dean. Just as they arrive the dean is called out of his office, leaving the three professors there. The professors see with alarm that there is a fire in the wastebasket. The physicist says, "I know what to do! We must cool down the materials until their temperature is lower than the ignition temperature and then the fire will go out." The chemist says, "No! No! I know what to do! We must cut off the supply of oxygen so that the fire will go out due to lack of one of the reactants." While the physicist and chemist debate what course to take, they both are alarmed to see the statistician running around the room starting other fires. They both scream, "What are you doing?" To which the statistician replies, "Trying to get an adequate sample size."
A photon is checking into a hotel and the bellhop asks him "Do you have any luggage?" The photon replies, "Nope, I'm traveling light."
A mathematician and an engineer agreed to take part in an experiment. They were both placed in a room and at the other end was a beautiful naked woman on a bed. The experimenter said every 30 seconds they would be allowed to travel half the distance between themselves and the woman. The mathematician said "this is pointless" and stormed off. The engineer agreed to go ahead with the experiment anyway. The mathematician exclaimed on his way out "don't you see, you'll never actually reach her?". To which the engineer replied, "so what? Pretty soon I'll be close enough for all practical purposes!"
An engineer and a physicist are in a hot-air balloon. After a few hours they lose track of where they are and descend to get directions. They yell to a jogger, "Hey, can you tell us where we're at?" After a few moments the jogger responds, "You're in a hot-air balloon." The engineer says, "You must be a mathematician." The jogger, shocked, responds, "yeah, how did you know I was a mathematician?" "Because, it took you far too long to come up with your answer, it was 100% correct, and it was completely useless."
Parallel lines have so much in common. It's a shame they'll never meet.
Q: Why was Pavlov's hair so soft? A: Classical conditioning.
A scientist tells a pharmacist, "Give me some prepared tablets of acetylsalicylic acid." "Do you mean aspirin?" asks the pharmacist. The scientist slaps his forehead. "That's it!" he says. "I can never remember the name."
