The Physicist: "The measurement wasn't accurate.".

The Biologist: "They have reproduced".

The Mathematician: "If now exactly one person enters the house then it will be empty again."

A physicist, an engineer and a mathematician were all in a hotel sleeping when a fire broke out in their respective rooms.

The physicist woke up, saw the fire, ran over to his desk, pulled out his CRC, and began working out all sorts of fluid dynamics equations. After a couple minutes, he threw down his pencil, got a graduated cylinder out of his suitcase, and measured out a precise amount of water. He threw it on the fire, extinguishing it, with not a drop wasted, and went back to sleep.

The engineer woke up, saw the fire, ran into the bathroom, turned on the faucets full-blast, flooding out the entire apartment, which put out the fire, and went back to sleep.

The mathematician woke up, saw the fire, ran over to his desk, began working through theorems, lemmas, hypotheses , you-name-it, and after a few minutes, put down his pencil triumphantly and exclaimed, "I have *proven* that I *can* put the fire out!" He then went back to sleep.

A Physicist, an engineer, and a mathematician are all locked in separate burning buildings.

The Physicist runs to a chalkboard, calculates exactly how much water he will need to put out the fire, runs and finds that ammount, puts out the fire, and survives.

The engineer pulls out a calculater, calculates exactly how much water he will need to put out the fire, runs and finds 10 times that ammount, puts out the fire, and survives.

The mathematician runs to a chalkbaord, calculates exactly how much water he will need to put out the fire, declares, "There IS a solution!", and then burns to death.

When considering the behaviour of a howitzer:

A mathematician will be able to calculate where the shell will land.

A physicist will be able to explain how the shell gets there.

An engineer will stand there and try to catch it.

Einstein dies and goes to heaven only to be informed that his room is not yet ready. "I hope you will not mind waiting in a dormitory. We are very sorry, but it's the best we can do and you will have to share the room with others." he is told by the doorman (say his name is Pete). Einstein says that this is no problem at all and that there is no need to make such a great fuss. So Pete leads him to the dorm. They enter and Albert is introduced to all of the present inhabitants.

"See, Here is your first room mate. He has an IQ of 180!"

"Why that's wonderful!" Says Albert. "We can discuss literature!"

"And here is your second room mate. His IQ is 150!"

"Why that's wonderful!" Says Albert. "We can discuss mathematics!"

"And here is your third room mate. His IQ is 100!"

"That's Wonderful! We can discuss the latest plays at the theater!"

Just then another man moves out to capture Albert's hand and shake it. "I'm your last room mate and I'm sorry, but my IQ is only 80." Albert smiles back at him and says, "So, where do you think interest rates are headed?"

* Life is like a urologist; it's hand is always cold. *

A theoretical Physicist, an experimental Physicist, and a mathematician are all locked in separate rooms for a week with only 1 can of soup and are told that if they want to eat they must find a way to open the can. After 1 week the rooms were opened:

The experimental Physicist's room had multiple dents in the walls, with a few soup stains, showing how he had thrown his can against the wall until he figured out the exact angle needed to open the can. He then threw the can at the wall at that angle, opened the can, and ate the soup.

The theoretical Physicist's room was covered in equations and 1 dent in the wall, showing he calculated the exact angle needed to open the can, threw the can at the wall at that angle, opened the can, and ate the soup.

The mathematician was found in his room seated on the floor with the unopened can repeating, "I define this can to be open!"

If you want to memorize names, become a biologist.

If you want to memorize exceptions, become a chemist.

If you want to memorize concepts, become a Physicist.

If you don't want to memorize anything, become a liberal arts major.

If it's green and wiggles, it's biology.

If it stinks, it's chemistry.

If it doesn't work, it's Physics.

One day a mathematician decides that he is sick of math and wants to be a fireman. So, the mathematician walks down to the fire department and announces that he wants to become a fireman.

The fire chief says, "Well, you look like a good guy. I'd be glad to hire you, but first I have to give you a little test."

The firechief takes the mathematcian to the alley behind the fire department which contains a dumpster, a spicket, and a hose. The chief then says, "OK, you're walking in the alley and you see the dumpster here is on fire. What do you do?" The mathematician replies, "Well, I hook up the hose to the spicket, turn the water on, and put out the fire." The chief says, "That's great... perfect. Now I have to ask you just one more question. What do you do if you're walking down the alley and you see the dumpster is not on fire?" The mathematician puzzles over the question for awhile and the finally says, "I light the dumpster on fire." The chief yells, "What? That's horrible! Why would you light the dumpster on fire?" The mathematician replies, "Well, that way I reduce the problem to one I've already solved."

News bulletin: A local Physicist declared that he has figured out the ingredients in McDonald's secret sauce: protons, nuetrons, and electrons.

A biologist, a chemist, and a Physicist are taking a walk through the country when they come upon a cow. For some odd reason, none of them knew what it was. The biologist thinks for a second and then declares, "I know what that is. That's Bos Bovine." The chemist looks for a second and the says, "It's just a carbon-based life form, approximately 75% water, and the remaining 25% trace elements." The Physicist stares blanky for a second and then says, "Well.... I guess we could approximate it as a sphere."

Engineers think that equations approximate the real world.

Scientists think that the real world approximates equations.

Mathematicians are unable to make the connection.

An engineer, a physicist, and a mathematician are shown a pasture with a herd of sheep, and told to put them inside the smallest possible amount of fence. The engineer is first. He herds the sheep into a circle and then puts the fence around them, declaring, "A circle will use the least fence for a given area, so this is the best solution." The physicist is next. She creates a circular fence of infinite radius around the sheep, and then draws the fence tight around the herd, declaring, "This will give the smallest circular fence around the herd." The mathematician is last. After giving the problem a little thought, he puts a small fence around himself and then declares, "I define myself to be on the outside!"

An engineer, a mathematician, and a computer programmer are driving down the road when the car they are in gets a flat tire. The engineer says that they should buy a new car. The mathematician says they should sell the old tire and buy a new one. The computer programmer says they should drive the car around the block and see if the tire fixes itself.
