Mathematical theory problem "the length of vertical line segment"
Is there any mathematical theory that can't be proved? There is a mathematical professional term called "independence"
A very famous example is the Cantor continuum hypothesis, which is the first of Hilbert's 23 questions.
Cantor's continuum hypothesis can neither be proved nor falsified in ZFC axiomatic system.
This "independence" was proved by Cohen, which is a very famous conclusion.
What did the college entrance examination show? What can you prove? The college entrance examination is a summary of a stage in your life. It can neither explain anything nor prove anything, but let us know how to go in the future and what kind of road to take. College entrance examination is not everyone's life.
What incompleteness theorem did mathematician Godel prove?
What is mathematics and what is mathematical theory? Mathematics is a subject that studies concepts such as quantity, structure, change and spatial model. By using abstract and logical reasoning, the shape and motion of objects are counted, calculated, measured and observed. Mathematicians have extended these concepts in order to express new conjectures with formulas and establish strictly deduced truths from properly selected axioms and definitions. Theory refers to people's understanding and elaboration of knowledge about things. Abbreviation: theory. For example, the understanding and elaboration of knowledge about things in the natural field is called natural science theory; The understanding and elaboration of social knowledge is called social science theory; The understanding and elaboration of knowledge in the field of thinking is called logical theory.
A mathematical theory problem is impossible, because a vertex has three sides and it is impossible not to repeat it.
This is related to topology.
Let this two-digit number be a mathematical theoretical problem in grade one of 10a+b,
Then reverse the position of its ten digits and single digits to form a new number10b+a.
The sum of the two numbers is:10a+b+1b+a =11(a+b).
Therefore, the rule is that their sum must be divisible by 1 1.
Why didn't anyone prove the problem of 1+ 1 mathematically? Any even number greater than 2 is the sum of two prime numbers, which is the Goldbach conjecture of 1+ 1.

What has science proved? Modern science has proved that there are about 654.38+00 billion nerve cells in the human brain, and there are 654.38+04 billion nerve cells in the cerebral cortex alone. The neural network composed of nerve cells in the human brain is far more complicated than all telegraph and telephone communication networks in North America. The human brain is not only different from higher animals in quality, but also in quantity. The weight of modern human brain is about 1500g, which is roughly equivalent to150 of body weight. Chimpanzees are 400g, which is roughly equivalent to1150 of their body weight; The gorilla weighs about 540g, which is roughly equivalent to 1/500 of its weight.
