The explanation of cold jokes in science! ! !

First of all, the first key is that two people go in and three people come out.

There is an uncertainty theorem in physics, that is, the motion of particles is uncertain for one second.

There is no "ongoing" process here, and there is no next second there, which means you never know.

Tell me where this particle will appear next second. In this joke, the physicist means

The superfluous man suddenly appeared in the shop out of nowhere and came out with them.

What biologists mean is that the two of them have bred another one together, so they have become three.

Mathematicians actually mean to go in two (plus two) and come out three (minus three), which is 2- 3=- 1. At this time, if you enter another one (plus 1), that is,-1+0 = 0, no one will be fooled.

But this is obviously inconsistent with reality, because there is no concept of negative population in our reality.

So it is easy to understand that mathematicians don't care about reality at all.

Now, the second key lies in the fit between academics and practice.

Engineers want to build. They want to study how the forces between objects act and how they are supported.

How to support a building and make it stress evenly can be expressed by formula, that is, equation.

We must combine closely with the reality so that our house will not collapse, so the engineers find their own way.

This program is very close to reality.

Physicists study the whole universe. They think everything fell from the needle to the ground.

The path to the universe, from your way of thinking to the psychology of the universe, can be expressed by formulas.

All belong to the category of physics, and the so-called "truth" that people feel is of course based on physical formulas.

Sometimes you feel that the reality is not like this, it's just your sensory error formula.

There is nothing wrong, that is to say, reality can go wrong and the formula is always right. That's what they do.

Mathematicians only study the internal harmony of numbers, such as the internal perfection of a system.

As for what reality is, mathematicians don't care much because they

The way of thinking is not based on real counting, such as the joke above.

hope this helps ...
