What are Einstein s life and contributions?

In terms of scientific method, Einstein focused on the deductive method. In terms of scientific contributions, Einstein was mainly involved in physics, but in physics, he made significant contributions in the two major contemporary scientific fields, relative mechanics and quantum mechanics; In relative mechanics in particular, he was the founder of the discipline. As for Einstein's revision of Newtonian mechanics, that is an inevitable consequence of the development of science.

After the amendment, Newtonian mechanics is still correct to the extent that it is applicable. Even Einstein's relative mechanics will inevitably be revised and developed. For example, in the physical state of ultra-high density and ultra-high temperature, Einstein's general theory of relativity is no longer applicable and must be revised.

But, all in all, both Newton and Einstein were scientific giants of their historical eras.

Einstein was born into a German Jewish family, was a scientist who invented many science and technology, the most important of which laid the foundation for the development of nuclear energy, and he was recognized as a great physicist in the world after Newton.

The mention of Albert Einstein brings to mind the theory of relativity, which of course is his main contribution, but his contribution is more than that. The reason why he is said to be the greatest scientist of the 21st century is because of his outstanding contributions to the theory of relativity and quantum mechanics.

1. The light meter of solar cells, burglar alarms and suspect cameras is based on the photoelectric effect.

2. Nuclear energy makes use of the physical phenomenon that when uranium atoms are fissioned, a small loss of total mass can be converted into energy, which is based on Einstein's famous equation e mc2. Today, nuclear energy provides 25% of the UK's electricity.

3. The reason why the global positioning system can accurately position the object to the meter is precisely according to Einstein's theory of relativity, which corrects the signal sent by the earth's satellite.

4. The special theory of relativity combined with quantum theory points out the existence of antimatter. Scientists use positrons, or antimatter "electrons," to study brain activity through X-ray line tomography.

5. The properties of subatomic particles are a direct result of the theory of relativity, and their existence can explain a variety of phenomena ranging from the properties of chemical elements to the action of magnets.

6. Einstein's research on photons from 1916 to 1917 laid the foundation for the discovery of lasers 40 years later. At present, lasers are widely used in a variety of products from *** to laser printers.
