Einstein began to learn music when he was young. At the age of six, he began to practice playing the violin. Music almost became Einstein's "second career", and violin accompanied him all his life.
Before Einstein went to school, his father gave him a compass (compass). The pointer of the compass always points to the North Pole and the South Pole, which fascinated Einstein for a long time. He remembered this impressive event until he became an adult.
Another experience left a deep impression on him. After a few years of school, he received a Euclidean geometry textbook, which proved many unquestionable axioms, which made him so curious that he could not learn according to the progress of the course, but learned it at one go.
Like Newton, Einstein was not precocious. He didn't speak until he was three years old, and he didn't act like a "child prodigy" during his whole study. He even looks mediocre and dull in the eyes of teachers. He is mainly dissatisfied with the teacher's rigid teaching methods, but he has strong independent and diligent exploration ability.
He taught himself basic mathematics including calculus and some theoretical physics knowledge in middle school. After entering the university, he often missed classes and studied classical theoretical physics and Maxwell's electromagnetic theory alone.

Einstein likes reading philosophical works and absorbing ideological nutrition from philosophy. He believes in the unity of the world and the consistency of logic. During the period of "Olympia Academy of Sciences", david hume's doubts about the universal validity of causality had an impact on Einstein.
The principle of relativity has been widely proved in mechanics, but it cannot be established in electrodynamics. Einstein questioned the logical inconsistency between the two theoretical systems of physics. He believes that the principle of relativity should be universally established, so the electromagnetic theory should have the same form for each inertial system, but there is a problem of the speed of light here.
Whether the speed of light is constant or variable becomes the primary question whether the principle of relativity is universally established. Physicists at that time generally believed in ether, that is, there was an absolute frame of reference, which was influenced by Newton's concept of absolute space. /kloc-At the end of 0/9, Mach criticized Newton's absolute view of time and space in Mechanics in Development, which left a deep impression on Einstein.
1905 One day in May, Einstein and a friend Bezo discussed the problem that had been explored for ten years. Bezo expounded his point of view according to Mahism, and they had a long discussion about it. Suddenly, Einstein realized something, went home and thought about it again and again, and finally figured it out. The next day, he came to Bezo's house again and said, thank you, my problem has been solved.
It turned out that Einstein thought clearly about one thing: there is no absolute definition of time, and time is closely related to the speed of optical signals. He found the key to the lock, and after five weeks of hard work, Einstein showed people the special theory of relativity.
Special relativity and general relativity have been established for a long time. It has stood the test of practice and history and is a recognized truth. Relativity has a great influence on the development of modern physics and modern human thought. Relativity logically unifies classical physics and makes it a perfect scientific system.
On the basis of the principle of special relativity, special relativity unifies Newton's mechanics and Maxwell's electrodynamics, pointing out that both of them obey the principle of special relativity and are covariant to Lorentz transformation, while Newton's mechanics is only a good approximate law of low-speed motion of objects.
On the basis of generalized covariation, general relativity establishes the relationship between local inertia length and universal reference coefficient through equivalence principle, obtains the generalized covariant forms of all physical laws, and establishes the generalized covariant gravity theory, and Newton's gravity theory is only its first-order approximation.
This fundamentally solved the problem that physics was limited to inertial system in the past, and got a reasonable arrangement in logic. Relativity strictly examines the basic concepts of physics such as time, space, matter and motion, and gives the time-space view and material view of scientific system, thus making physics a perfect scientific system logically.
