Who knows a joke about different scientists having different views on something? I don't remember how to say it

The physics professor walked across the campus and met the math professor. The physics professor is conducting an experiment. He summed up an empirical equation, which seems to be consistent with the experimental data. He asked the math professor to look at the equation. A week later, they met, and the math professor said the equation was invalid. But at that time, the physics professor had predicted the further experimental results with his equation, and the effect was quite good, so he asked the math professor to review the equation again. Another week later, they met again. The math professor told the physics professor that this equation really holds, "but it only applies to the simple case of positive real numbers."

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 the problem that N-dimensional twisted nails penetrate N- 1 dimensional super walls in N-dimensional space. Many basic theorems have been proved ... Of course, the depth of this topic makes the existence of simple solutions far from obvious.

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 said, "I'm outside now."

Physicists and engineers got lost in a hot air balloon in the Grand Canyon. They shouted for help: "Hello! Where are we? " After about 15 minutes, they heard the response echoing in the valley: "Hey! You are in a hot air balloon!

"The physicist said," That guy must be a mathematician. " The engineer wondered, "Why?" The physicist said, "Because it took him a long time to give a completely correct answer, but it was useless. "

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 also woke up smelling smoke. He found cigarette butts burning 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 combustible materials from oxygen. Watering can do both. "So he dragged the trash can into the bathroom, turned on the tap to put out the fire, and then went back to sleep. The mathematician saw all this outside the window, so after a while, he was not worried at all when he found his ash burning the sheets. He said, "Hey, the solution exists! "I went back to sleep.

Mathematicians, biologists and physicists sit in street cafes and watch people go in and out of the house across the street. They first saw two people walk in. Time goes by. They saw three people coming out. Physicist: "The measurement is not accurate enough." Biologist: "They reproduce." Mathematician: "If one more person goes in now, the house will be empty."

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 and finally replied, "I'll just set fire to the warehouse." The fire chief shouted, "What? That's terrible! Why did you set fire to the warehouse? " The mathematician replied, "In this way, I will simplify the problem into a problem that I have solved."

A group of mathematicians are measuring the height of the flagpole. They only have a tape measure, so it is difficult to fix it on the flagpole, because the tape measure always falls off. A physicist walked by and pulled out the flagpole, so it was easy to measure the data. After he left, one mathematician said to the other, "Physicists always do this. We asked for height, but he gave us length! " "

Physicists, astronomers and mathematicians happened to see a black sheep while walking on the Scottish Plateau. "Ah," said the astronomer, "so Scottish sheep are black." "Come on, you can't just say that based on one observation." The physiologist said, "You can only say that black sheep were found in Scotland." "No," said the mathematician, "you can only say so from this observation.

There must be. It's all about mathematicians.
