Einstein Biography
He has made outstanding achievements in scientific research all his life, the most outstanding of which is that he proved the existence of atoms by experiments, founded the theory of relativity and developed the quantum hypothesis put forward by Planck. Einstein, a famous German physicist, made outstanding contributions to the development of modern physics all his life. His most outstanding achievement is to break through the framework of Newton's classical physics and create the theory of relativity suitable for the field of microscopic high-speed motion.
Before Einstein, since ancient times, people thought that although matter existed in time and space and their movement was restricted by time and space, time and space were not affected by the distribution and movement of matter. In this way, time, space, matter and movement are completely separated and isolated. Newton, a gifted physicist, also believed this view and put forward the concepts of absolute time, absolute space and absolute motion. Einstein disagreed with Newton's view of absolute time and space and absolute motion. Starting from the limited speed of light, he proposed that the time simultaneity of the universe is relative to a certain reference system, for example, the time of events on the moon is relative to the earth reference system. Based on the relativity of simultaneity, he denied Newton's concepts of absolute time, absolute space and absolute motion. Because the simultaneity of time is relative to a certain frame of reference, it is relative; And movement is closely related to time, so movement is also relative. Looking at the earth in isolation, its movement does not exist; Space and time are closely linked, so absolute space does not exist. Thus, Einstein linked seemingly unrelated time and space, making them a closely linked unity of opposites, and founded the special theory of relativity in 1905.
19 16 years, Einstein further completed the establishment of general relativity after 10 years of exploration. General relativity is a new theory of gravity without gravity and a physical law applicable to all reference systems. It is different from special relativity, which only applies to physical processes without gravity. The reference frame of relative motion of a straight line with uniform speed is studied. General relativity studies the frame of reference of any motion, which is not only applicable to the frame of reference of straight line and uniform motion, but also to the frame of reference of accelerated motion and rotary motion, so it is the second floor of the building of relativity. General relativity further shows that time and space are not isolated, and the distribution and motion of matter in turn determine the structure of time and space. They also influence each other and are the unity of opposites. Einstein's theory of relativity is the most important achievement of modern science and technology in the magical century, which led to a complete revolution in ancient physics, completed the third theoretical synthesis of physics, and further laid the cornerstone for the development of modern physics.
