First, the significance of the miracle year paper:

Miracle year papers refer to four papers published by Albert Einstein in the German scientific magazine Physical Yearbook in 1905. These four papers have promoted the foundation of modern physics and made people re-understand space, time, mass and energy. 1905 is also called Einstein's miracle year.

Second, Einstein's brief introduction:

Albert Einstein (1March 87914-1April 95 18), born in Ulm, Baden-Wü rttemberg, Germany, is a Jewish physicist with dual citizenship of the United States and Switzerland.

1900 graduated from Swiss Federal Institute of Technology in Zurich and became a Swiss citizen. 1905, Einstein received his Ph.D. in physics from the University of Zurich, put forward the photon hypothesis, and successfully explained the photoelectric effect (so he won the Nobel Prize in Physics in 192 1 year). In the same year, the special theory of relativity was founded.

General relativity was founded in 19 15, and moved to the United States in 1933 to work in Princeton Institute for Advanced Studies. He became an American citizen on 1940, while retaining Swiss nationality. 1955 In April, Einstein died in Princeton, New Jersey at the age of 76.

Einstein's achievements

1, relativity:

Einstein put forward special relativity and general relativity, which completely changed our understanding of space, time and gravity.

2, photoelectric effect:

Einstein explained the photoelectric effect, and thus won the Nobel Prize in Physics in 192 1 year.

3. Mass-energy equation:

Einstein put forward the famous mass-energy equation E=mc? , revealing the relationship between mass and energy.

4. Boltzmann entropy formula:

Einstein made an important contribution in the field of statistical physics and put forward the famous Boltzmann entropy formula.

5. Cosmic constant:

Einstein introduced the cosmological constant into the early study of cosmology, which had an important influence on the further development of cosmology.

6, the nucleus:

Einstein explained the composition and radioactive decay of nuclear, which laid the foundation for the development of nuclear physics.

7, philosophy of science:

Einstein is a master of philosophy of science of critical school.
