Mathematicians and their girlfriends are walking in the park. His girlfriend asked him, "Do you really mind my freckles?"

The mathematician replied softly, "Absolutely not! I was born to like dealing with decimal points. "

Statisticians

A statistician who has never taken care of his children reluctantly agreed to take care of four young and active children when his wife went shopping on Saturday afternoon. When his wife came home, he handed her a note that read: "Wipe your tears 1 1 time; Tie shoelaces 15 times; Blow toy balloons for each child five times, and the average life of each balloon is 10 second; Warning children not to cross the road 26 times; The child insisted on crossing the road 26 times; I want to do it again on Saturday. "

Once upon a time, there was a man who kept many chickens. He hasn't studied since he was a child, and he doesn't know a word. He can't even count the numbers. He doesn't know how many chickens he has. what should he do ？ Finally, he thought of pairing. He counted the chickens in pairs, and he knew that the number of chickens was even.

So he counts the logarithm of chickens every day. He was thinking: I don't know if he died one day or was stolen. He thinks this is very practical, so he will repeat it at night. One night, his neighbor sneaked into his house ... and stole a chicken. The next morning, the chicken breeder began to count the logarithm of chickens.

He counted in pairs and finally found himself ordering one. He knew that the only one was stolen by his neighbor. He scolded: thief, robber, smelly bastard, give me back the chicken quickly. Do you think I am an idiot? Neighbors were angry when they heard him scolding himself.

In the evening, his neighbor stole another chicken from his house. The next day, the chicken breeder routinely counted the logarithm of chickens.

I found that all the chickens were right, and the neighbors who wanted to steal them had already returned them.

"... you thief, son of a bitch, he shouted at his neighbor, but he didn't scold you like that. Will you give it back to Lao Tzu? It's not for Lao tze! "Knock into a nail

Engineers, physicists and mathematicians received a task at the same time: nailing the wall.

The engineer built a universal nailing machine, that is, a machine that can nail any possible nail into any possible wall.

Physicists have done a series of tests on the strength of hammers, nails and walls, and then developed a revolutionary technology-ultra-low-temperature ultrasonic nailing technology.

Mathematicians extend the problem to N-dimensional space, and consider the problem that a kinked 1 dimensional nail penetrates the N- 1 dimensional super wall. Many basic theorems have been proved ... Of course, the depth of this topic makes the existence of simple solutions far from obvious.

Fence fence

A farmer invited engineers, physicists and mathematicians to enclose the largest area with the least fences.

The engineer fenced a circle and declared that it was the best design.

The physicist stretched the fence into a long straight line. Assuming that the fence is infinitely long, they think it is big enough to surround half the world.

The mathematician gave them a big laugh.

He surrounded himself with several fences and then said, "I'm outside now."

catch fire

Engineers, chemists and mathematicians live in three adjacent rooms of an old inn. At first, the engineer's coffee machine caught fire that night. He woke up smelling the smoke, unplugged the coffee machine, threw it out of the window, and then went to sleep.

After a while, the chemist woke up and smelled smoke. He found that cigarette butts lit the trash can. He said to himself, "How to put out the fire? We should lower the fuel temperature below the ignition point and isolate the combustion products from oxygen. Watering can do both at the same time. " So he dragged the trash can into the bathroom, turned on the tap to put out the fire and went back to sleep.

The mathematician saw all this outside the window, so after a while, when he found his ashes burning the sheets, he was not worried at all. He said, "Hey, the solution exists!" "I went back to sleep.

Mathematicians become firefighters.

One day, the mathematician felt that he had had enough of mathematics and ran to the fire brigade to announce that he wanted to be a fireman. The fire chief said, "You look good, but I have to give you a test first."

The fire chief took the mathematician to the backyard alley of the fire brigade. There is a warehouse, a fire hydrant and a hose in the alley. The fire chief asked, "Suppose the warehouse was on fire, what would you do?" The mathematician replied, "I connected the fire hydrant to the water pipe, opened the water pipe and put out the fire."

The fire chief said, "Exactly! Last question: suppose you walk into an alley and the warehouse is not on fire, what would you do? " The mathematician pondered for a long time in doubt and finally replied, "I will set fire to the warehouse." The fire chief shouted, "What? That's terrible! Why did you set fire to the warehouse? " The mathematician replied, "So I can simplify the problem to a problem I have solved, and listen to the class alone in a classroom with only three people." After a while, four people came out and approached 1 person. The man said, "The classroom is finally empty." Yes "
