This seems to be a very "small" problem, which is not worth discussing and studying. However, when you read Cosmology and The Theory of Everything, you will realize that this is still a very "big problem". To answer this question correctly, you need to know the laws of the universe and the movement of everything, and know a lot of knowledge such as physics, chemistry and mathematics. It involves not only cosmology, physics, chemistry, mathematics and other scientific research. After solving this problem, you will find many important scientific research clues and make many significant achievements in the fields of mathematics, physics, chemistry, cosmology, life science and medicine. Because I have a hint in cosmology and an introduction to everything, I will simply give a clue for the reference of friends who study cardiology, physics, chemistry, life science and medicine.
First, "addition, subtraction, multiplication and division" in the universe
There is only the phenomenon and law of "addition and subtraction" in the universe, but there is no phenomenon and law of "multiplication and division". "Multiplication and division" is a law created by human beings for convenient operation, and it is another manifestation of the law of "addition and subtraction". Everything is the result of the law of addition and subtraction, and it follows the law of addition and subtraction rather than the law of multiplication and division. The laws of cosmic motion also make it impossible for everything to "multiply and divide". If we master this law, we can find many important scientific research clues and make breakthrough achievements in mathematics and physics.
Second, why are some numbers inseparable?
1. Because there is no such thing as division in the universe. Without this kind of thing, this kind of thing naturally has no solution, so it can't "divide" some numbers, but it can only be a very unreal "divisor" The application of untrue numbers in any aspect will inevitably produce untrue results and cause irreparable losses to mankind.
2. Because the division of matter is extremely limited. For a long time, people have been influenced by the wrong theory that "matter can be divided infinitely", and everyone thinks that everything can be divided, so they have created a division operation method. Although some numbers are not divisible, people still believe that it is scientific to do so, and they don't realize that there is nothing in the universe that can be divisible indefinitely, so some numbers can't be divisible.
Nothing in the universe has "a characteristic". I will call this characteristic "S motion" for the time being. All matter in the universe has this "most basic feature". However, for a long time, people have always thought that matter has no "this characteristic". So far, people are still aware of this and have not found this "feature", which naturally leads to many mistakes in human basic research from the beginning. This is one of the main reasons for many mistakes and stagnation in physics, mathematics, chemistry, medicine, life sciences, astronomy, philosophy and other sciences in the world at present, and it is also the most fundamental key reason.
There are only integers in the universe. Although there are even numbers and odd numbers in the universe, they are all integers and there is no "non-integer" at all. Therefore, "division" is contrary to the law of motion of all things in the universe, and it is impossible to simply use "division" to calculate and solve problems. Otherwise, there will be an "inseparable" problem.
Third, correctly treat "multiplication and division"
Although "multiplication and division" is not a "material" but a creation of human beings, it can facilitate human research and life, so it can be used. But we should pay attention to one thing, that is, we can't easily use the divisor "about equal to" in division, because the universe and everything are a very scientific and rigorous system, and a little difference will lead to very different results, which will inevitably lead to counterproductive consequences.
This is a big topic, a very important topic, and also a very interesting topic. I hope I can play a role in attracting jade and help my friends achieve greater success! .
