1. Schrodinger's cat
Erwin Schrodinger's cat in the 20th century In the middle of the decade, he created an equation in what is now called the branch of quantum mechanics. It was later called the Schrödinger equation: ▽²ψ(x,y,z)+(8π²m/h²)[EU(x,y,z)]ψ(x,y,z)=0.
Quantum theory is the science of the 20th century One of the major developments, but due to the tremendous impact of quantum mechanics on traditional concepts, even the authors of "quantum" have tried every means to reject it or make various conciliatory explanations. In fact, Schrödinger was disturbed by the results of quantum mechanics. He did not like the binary interpretation of wave-particle duality and the statistical interpretation of waves, and tried to establish a theory that only uses waves to explain.
Schrödinger tried to use an ideal experiment to test the implicit inaccuracies of quantum theory.
The Schrödinger cat is an ideal experiment on quantum theory. This cat is very pitiful. She (assuming this is a female cat to arouse more pity) is sealed in a secret room with food and poison. There is a hammer on the poison bottle. The hammer is controlled by an electronic switch, and the electronic switch is controlled by radioactive atoms. If the nucleus decays, alpha particles are released, the electronic switch is triggered, the hammer falls, smashes the poison bottle, and releases the cyanide gas inside. There is no doubt that female cats will die. This cruel device was designed by Schrödinger, so this cat is called Schrödinger’s cat.
According to common sense, the cat may be dead or alive. But quantum mechanics tells us that there is an intermediate state, and the cat is neither dead nor alive until we observe what happens.
Quantum mechanics tells us: Unless we make observations, nothing is real. Einstein and a few non-mainstream physicists refused to accept the theoretical results created by Schrödinger and his colleagues. Einstein believed that quantum mechanics is only a reasonable description of the behavior of atoms and subatomic particles. It is a phenomenological theory, and it is not the ultimate truth in itself. He once said a famous saying: "God does not roll dice." He does not recognize Schrödinger's extrinsic state of cats, and believes that there must be an internal mechanism that constitutes the true nature of things. He spent several years trying to design an experiment to test whether this inner authenticity really worked, but he passed away without completing the design.
2. String theory
String theory, or string theory, is a theory in theoretical physics. A basic view of string theory is that the basic units of nature are not particles such as electrons, photons, neutrinos and quarks. These things that look like particles are actually closed loops of very small strings (called closed strings or closed strings). The different vibrations and motions of closed strings produce various elementary particles. String theory is The most promising theory now is to unify the fundamental particles of nature and the four interaction forces.
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 in the nucleus, and then he found the 200-year-old Euler's Function in an old mathematics book. This formula can successfully describe what he has learned. Strong force that requires solution. However, further understanding of this formula as a small elastic "line segment" that can be twisted and shaken like a rubber band was discovered by Leonat Suskan not long after, which later developed the "string theory".
Although string theory was originally intended to solve the mode of action of strong forces, later research has discovered all the most basic particles, including quarks and anti-quarks, electrons and anti-neutrinos, etc., as well as four basic The force "particles" (strong and weak force particles, electromagnetic force particles, and gravity particles) are composed of a short string of energy that keeps shaking, and the difference between various particles is only this string. The way and shape of the line jitter is different.
String theory attracts so much attention, mostly because it is likely to become a unified theory. String theory may also be one of the solutions to quantum gravity. In addition to gravity, it naturally successfully described various forces, including electromagnetic forces and other forces that exist in nature. Superstring theory also includes fermions, one of the elementary particles that make up matter. As to whether string theory can be successfully explained based on the universe composed of all the forces and matter currently known in the physical world and applied to "black holes", this is still unknown

Finally, I used the head of ordinary people to think: The multiple parallel worlds proposed by Schrödinger cat explain the cat’s Life and death is entirely caused by the intervention of the consciousness, which ends the cat’s quantum superposition state, and makes the cat’s wave function immediately shrink from the superposition state to a certain eigenstate. The entire logical overturning process and narrative are very organized, so can we? Come to the conclusion that consciousness determines matter??? Wave-particle dichroism and string theory try to unify the micro and macro, but the problem is that no one can prove its absolute correctness and wide applicability, and Einstein did not have it in his entire life. Completed the study of the theory of unification, science and philosophy, entangled from ancient times to the present. Even Newton, his later years also compromised theology. As Leonard told Panny, "We have nothing new in physics except string theory since 1930." , And string theory has not yet been proven..."
In fact, physics and philosophy are similar in many places, and the logical and speculative abilities of outstanding physicists are extremely powerful~ so our dear Lord Sheldon can always be here Winning in a boring debate...The
last sentence: Lord Sheldon, I have fallen deeply at your feet~ You are the king of the universe~~~~
Haha~ It seems a bit far away...
