What great contribution did Einstein have

Albert Einstein is one of the most creative and intelligent figures in human history, and his main contributions are: he pioneered four fields of physics during his lifetime: the special phase combustion theory, the general theory of relativity, cosmology, and the unified bridge fiber field theory.

He is one of the main founders of the theory of quantum-sensitive segment imitation, and has also made significant contributions to the theory of molecular motion and quantum statistics.

Albert Einstein proposed a combination of special relativity and quantum theory, which pointed to the existence of antimatter, and later scientists used positrons, also known as antimatter "electrons", to study the activity of the human brain by X-ray tomography.

Albert Einstein proposed that nuclear energy takes advantage of the physical phenomenon that when uranium atoms are fissioned, a small loss of their mass can be converted into energy. This is also based on Einstein's famous equation e=mc2. At present, many countries in the world use nuclear energy for power supply.

Einstein's research on photons laid the foundation for the development of lasers in later generations, and lasers are now widely used in a variety of electronic products from laser printers to laser printers.

The GPS can be used to accurately position objects down to the meter, based on Einstein's theory of relativity, on which the signals emitted by the Earth's satellites are corrected.

Einstein's important contributions to physics.

At the critical moment of the crisis of classical physics in the early 20th century, Einstein was a glorious banner to promote the revolutionary ideas of physics. He independently discovered the special theory of relativity and the general theory of relativity, which fundamentally changed the traditional concept of absolute space-time, unifying space-time, matter, and force through symmetry. Starting from the special theory of relativity, he proposed the formula of mass and energy equivalence, opening up the era of atomic energy.

Starting from general relativity and nuclear energy, he and a group of scientists developed models of the structure and origin of the universe, and the cosmological constant he proposed predicted the existence of dark energy that produces repulsive forces. Together with Purne and Bohr, he was the main founder of quantum theory, and he proposed the quantum theory of light that combined wave and particle, explained the photoelectric effect, and promoted the discovery of quantum wave dynamics. He developed atomic theory and statistical mechanics, explained a series of phenomena from Brownian motion, specific heat of solids to stimulated radiation, and cooperated with Bose to establish Bose Einstein's theory of quantum statistics, which foresaw the existence of Bose condensate.

He questioned quantum mechanics and proposed quantum entangled states, opening up a new field of quantum informatics. In his later years, he devoted himself to the unified field theory, and although he did not achieve the expected results, his idea of unifying the interaction force from the perspective of high-dimensional geometric local symmetry still guides the development direction of the grand unified theory of fundamental interactions, and has been embodied in the unification of weak and strong interactions in the half century after his death.

His scientific ideas were far ahead of his time, and were so forward-looking and profound that many of his important theories were not universally recognized by the physics community in a short period of time after they were published. His scientific discovery was not a genius's whim, but through self-study to master the most cutting-edge scientific achievements at that time, and after years of arduous thinking, Yu returned to the forest. In his last year of high school, he had already studied the theory of electrodynamics, which had not yet been taught at university, and thought about the phenomena that would occur when moving with light, and it was only 10 years later that he discovered the special theory of relativity.

In 1908, he proposed the task of popularizing the special theory of relativity to the acceleration coordinate system, and in 1909 he began to realize the equivalence relationship between acceleration and gravity, and after six years of efforts and many failures, he established the correct gravitational equation of general relativity in 1915.

The theory of relativity and quantum mechanics are the most important scientific discoveries of the 20th century, which not only provide us with images and laws of matter and motion from microscopic quarks to macroscopic universes, enrich our view of matter and the universe, but also provide a scientific basis for the development of technology in the 20th century. Although Einstein was engaged in basic research, he did not know what practical value these studies had, but the more basic the law, the wider the phenomenon, the wider the potential application, and the greater the value. The influence of Einstein's research results can be seen in a wide range of technologies such as optoelectronics, lasers, atomic energy, GPS, sensors, accelerators, and information privacy.
