Poem with strings

The verses with strings are as fast as horses, and the strings are as startling as thunderbolts. There are fifty strings of brocade strings for no reason, each string and column is reminiscent of the past. I feel that I have been saying this for a long time, but sitting down makes the strings turn sharply.

String

String is a physics term, defined as a short section of "energy string" that is the most basic unit of all matter. The physical model in string theory believes that the most basic unit of all matter is a small "energy string".

Elementary particles as large as interstellar galaxies and as small as electrons, protons, and quarks are all composed of "energy lines" that occupy one degree of space (lines with only length and no width). In Chinese translation, it is usually translated as "string".

The particle theory established earlier believes that all matter is composed of "point" particles occupying only zero-dimensional space. It is also a widely accepted physical model at present, and it has also been very successful in explaining and It predicts quite a few physical phenomena and problems, but the "particle model" on which this theory is based encounters some unexplainable problems.

In comparison, "string theory" is based on the "wave model", so it can avoid the problems encountered by the former theory. The deeper string theory theory not only describes "string"-like objects, but also includes point-like and film-like objects, higher-dimensional spaces, and even parallel universes.

It is worth noting that since strings cannot be directly observed, string theory has not yet been able to make accurate predictions that can be experimentally verified. This will be explained below.

Knowledge expansion:

The prototype of string theory was discovered by Gabriele Veneziano in 1968. He was originally looking for a mathematical formula that could describe the strong force within the nucleus, and then found the 200-year-old Euler's formula (Euler's formula) in an old mathematics book. This formula could successfully describe what he wanted to solve.

However, the further understanding of this formula as a small elastic "line segment" that can twist and shake like a rubber band was discovered not long ago by Leonard Su Shikan. In the future, "string theory" was developed.
