The story about Einstein should be very short.

Albert. Einstein (1March 87914-1April 955 18) was born in Ulm, Wü rttemberg, Germany, and graduated from Federal Institute of Technology in Zurich as a Jewish physicist.

Einstein was born in a Jewish family in Ulm, Germany on 1879. 1900 graduated from the Federal Institute of Technology in Zurich and became a Swiss citizen. 1905 received a doctorate from the University of Zurich. Einstein put forward the photon hypothesis and successfully explained the photoelectric effect. So he won the Nobel Prize in physics at 192 1 and founded the special theory of relativity at 1905.

General relativity was founded in 19 15. 1April 1955 18 died at the age of 76.

Einstein laid a theoretical foundation for the development of nuclear energy and initiated a new era of modern science and technology, and was recognized as the greatest physicist after Galileo and Newton. 199965438+On February 26th, Einstein was selected as "the great man of the century" by American Time magazine.

Extended data

The main achievements of Einstein's life:

1, the establishment of special relativity

As early as 16 years old, Einstein learned from books that light is a fast electromagnetic wave. Related to this, he would like to discuss the so-called etheric problem related to light waves. The word ether comes from Greece and is used to represent the basic elements that make up objects in the sky.

2. The establishment of general relativity

1905, after Einstein published the first article about the special theory of relativity (that is, on electrodynamics of moving objects), Planck, an authoritative figure in German physics, noticed his article and thought that Einstein's work could be comparable to Copernicus's. It is precisely because of Planck's promotion that Einstein also attracted the attention of academic circles.

3, photoelectric effect

1905, Einstein put forward the photon hypothesis and successfully explained the photoelectric effect, so he won the 192 1 year Nobel Prize in Physics. When light irradiates a metal, the electrical properties of this substance will change. This photochromic phenomenon is collectively called photoelectric effect.

4. Law of Conservation of Energy

E=mc？ , the law of material immortality, said the immortality of the material quality; The law of conservation of energy is about the conservation of energy of matter.

5. Cosmic constant

Einstein used the cosmological constant when he put forward the theory of relativity (in order to explain the existence of a static universe with non-zero density of matter, he introduced a term in the gravitational field equation that is proportional to the metric tensor, which was represented by the symbol λ. This proportional constant is very small and can be ignored at the galactic scale. λ is only meaningful at the cosmic scale, so it is called the cosmological constant.
