The experimentalist comes running excitedly into the theorist's office, waving a graph taken off his latest experiment. "Hmmm," says the theorist, "That's exactly where you'd expect to see that peak. Here's the reason (long logical explanation follows)." In the middle of it, the experimentalist says "Wait a minute", studies the chart for a second, and says, "Oops, this is upside down." He fixes it. "Hmmm," says the theorist, "you'd expect to see a dip in exactly that position. Here's the reason...".
A Princeton plasma physicist is at the beach when he discovers an ancient looking oil lantern sticking out of the sand. He rubs the sand off with a towel and a genie pops out. The genie offers to grant him one wish. The physicist retrieves a map of the world from his car an circles the Middle East and tells the genie, "I wish you to bring peace in this region".
After 10 long minutes of deliberation, the genie replies, "Gee, there are lots of problems there with Lebanon, Iraq, Israel, and all those other places. This is awfully embarrassing. I've never had to do this before, but I'm just going to have to ask you for another wish. This one is just too much for me".
Taken aback, the physicist thinks a bit and asks, "I wish that the Princeton tokamak would achieve scientific fusion energy break-even."
After another deliberation the genie asks, "Could I see that map again?"
What is the difference between a physicist, an engineer, and a mathematician?
If an engineer walks into a room and sees a fire in the middle and a bucket of water in the corner, he takes the bucket of water and pours it on the fire and puts it out.
If a physicist walks into a room and sees a fire in the middle and a bucket of water in the corner, he takes the bucket of water and pours it eloquently around the fire and lets the fire put itself out.
If a mathematician walks into a room and sees a fire in the middle and a bucket of water in the corner, he convinces himself there is a solution and leaves.
An experimental physicist performs an experiment involving two cats, and an inclined tin roof. The two cats are very nearly identical; same sex, age, weight, breed, eye and hair color. The physicist places both cats on the roof at the same height and lets them both go at the same time. One of the cats fall off the roof first so obviously there is some difference between the two cats.
What is the difference? One cat has a greater mew.
French physicist Ampere (1775-1836) had two cats, one big and a one small, and he loved them very much. But when the door was closed cats couldn't enter or exit the room. So Ampere ordered two holes to be made in his door: one big for the big cat, and one small for the small cat.
A psychologist makes an experiment with a mathematician and a physicist. He puts a good-looking, naked woman in a bed in one corner of the room and the mathematician on a chair in another one, and tells him: "Iґll half the distance between you and the woman every five minutes, and youґre not allowed to stand up." the mathematician runs away, yelling: "in that case, Iґll never get to this woman!". After that, the psychologist takes the physicist and tells him the plan. The physicist starts grinning. the psychologist asks him: "but youґll never get to this woman?", the physicists tells him: "sure, but for all practical things this is a good approximation."
There is this farmer who is having problems with his chickens. All of the sudden, they are all getting very sick and he doesn't know what is wrong with them. After trying all conventional means, he calls a biologist, a chemist, and a physicist to see if they can figure out what is wrong. So the biologist looks at the chickens, examines them a bit, and says he has no clue what could be wrong with them. Then the chemist takes some tests and makes some measurements, but he can't come to any conclusions either. So the physicist tries. He stands there and looks at the chickens for a long time without touching them or anything. Then all of the sudden he starts scribbling away in a notebook. Finally, after several gruesome calculations, he exclaims, "I've got it! But it only works for spherical chickens in a vacuum."
