Einstein/Kloc-graduated from Zurich University of Technology in 0/900, and began to teach in this university in 0/909. 19 14 was the director of the Royal William Institute of Physics and a professor at the University of Berlin. Later, he was forced to immigrate to the United States and 1940 became an American citizen.
/kloc-the late 0/9th century is a period of change in physics. Einstein re-examined the basic concepts of physics from the experimental facts and made a fundamental breakthrough in theory. Some of his achievements greatly promoted the development of astronomy. His quantum theory has a great influence on astrophysics, especially theoretical astrophysics. The first mature aspect of theoretical astrophysics-stellar atmosphere theory is based on quantum theory and radiation theory. Einstein's special theory of relativity successfully revealed the relationship between energy and mass and solved the long-standing problem of stellar energy. In recent years, more and more high-energy physical phenomena have been discovered, and special relativity has become the basic theoretical tool to explain this phenomenon. His general theory of relativity also solved a mystery in astronomy for many years, and deduced the phenomenon of light bending that was later verified, which became the theoretical basis of many astronomical concepts later.
Einstein's greatest contribution to astronomy is his cosmology. He founded relativistic cosmology, established a static finite and infinite self-consistent dynamic universe model, and introduced new concepts such as cosmology principle and curved space, which greatly promoted the development of modern astronomy.

1965438+In April 2004, Einstein accepted the invitation of the German scientific community and moved to Berlin.
World War I broke out in August. Although he lived in the birthplace of war and was surrounded by war advocates, he firmly showed his anti-war attitude.
In September, Einstein participated in launching the anti-war group "New Motherland Alliance". Although the organization was declared illegal and a large number of its members were arrested and persecuted and went underground, Einstein resolutely participated in the secret activities of the organization.
On June+10, 5438, under the manipulation and instigation of militarists, the German scientific and cultural circles published the Declaration of Civilized World, defending the aggressive war launched by Germany, arguing that Germany is above all else and the whole world should accept the "true German spirit". Ninety-three people signed the declaration, all of whom were prestigious scientists, artists and priests in Germany at that time. Even Nernst, Roentgen, ostwald and Planck signed it. When asked for Einstein's autograph, he flatly refused, but at the same time resolutely signed his name on the anti-war letter to Europeans. This move shocked the whole world.

19 17. After the victory of the Soviet socialist revolution led by Lenin, Einstein enthusiastically supported this great revolution and praised it as a great social experiment that will be decisive for the whole world. He said: "I respect Lenin because he is a man with complete self-sacrifice spirit and devoted himself wholeheartedly to realizing social justice. I don't think his method is practical, but one thing is certain: people like him are defenders and reconstructors of human conscience. "
19181kloc-0/October, German workers and soldiers, influenced and inspired by the victory of the October Revolution in Russia, launched an uprising and overthrew the German emperor William II. On the third day after stepping down, Einstein wrote two postcards to his mother, cheering "a great event happened ... what an honor to experience it personally!" " From the 1920s to the early 1930s, Einstein was basically an absolute pacifist. However, the fact that wars of aggression and plunder are constantly happening has broken his beautiful dream. Especially after Hitler came to power in 1933, Germany became increasingly fascist, which made Einstein realize that a new barbaric war was inevitable and prompted him to change his point of view. He made it clear: "When the law and human dignity must be defended, we must fight. Since the danger of fascism came, I no longer believe that absolute negative pacifism is effective. As long as fascism rules Europe, there will be no peace. " Because of Einstein's progressive activities and because he was a Jew, he was listed as an important persecution object by the German Nazis. Fortunately, he left Germany to give lectures in the United States at the end of 1932 and was not killed. His house in Berlin was raided and destroyed, his property was confiscated and his works were burned. The Nazis offered a reward of 20,000 marks to kill him. Faced with the danger of Nazi assassination, Einstein did not have the slightest fear, but fought more resolutely. When his close friend Laue wrote to persuade him to take a wise attitude on political issues, he ignored his personal safety and shouted, pointing out that fascism means war, and peace must be defended by armed forces, calling on the American people to rise up against fascism. Einstein was very sad when he later learned on the radio that the United States dropped atomic bombs on Hiroshima and Nagasaki, causing many civilian casualties. Later, he wrote a letter to American citizens, in which he said: "We scientists who liberated this great power should give priority to taking responsibility for everything, and must limit that atomic energy should never be used to kill all mankind, but should be used to enhance human happiness."
19 19 Einstein's theory is considered as "one of the greatest achievements in the history of human thought". In February, 65438, he received the only honorary degree in Germany: the doctorate of medicine from the University of Rostock.
1921From April 2 to May 30, Weizmann and I visited the United States for the first time in order to raise funds for the establishment of the Hebrew University of Jerusalem in Jerusalem.
1922 1 completed the first paper of unified field theory. In July, he was threatened with murder and temporarily left Berlin. On October 8th, 65438/KLOC-0, Einstein and Elsa went to Japan by boat in Marseille. Visit Colombo, Singapore, Hong Kong and Shanghai along the way. 165438+1On October 9th, Einstein was awarded the Nobel Prize in Physics 192 1 year. 165438+1October17-65438+February 29th, I have been to Japan.
1923 In July, he went to Gothenburg to receive the Nobel Prize of 192 1. In February 65438, it was first speculated that the quantum effect might come from the overconstrained field equation of general relativity.
Bose-Einstein condensation was discovered in 1924.
After 1925, Einstein went all out to explore the unified field theory In the first few years, he was optimistic that victory was in sight; Later, he found many difficulties, and he thought that the existing mathematical tools were not enough.
During the 30 years from 1925 to 1955, except for the completeness of quantum mechanics, gravitational waves and general relativity, Einstein devoted almost all his scientific creative energy to the exploration of unified field theory.
1926 was elected as an academician of the Soviet Academy of Sciences.
Exploration of the transition from 1928 to pure mathematics. He tried various methods, but he didn't get any results with real physical significance.
In June 5438+10, he was elected as the director of "German Human Rights League" (formerly known as "German New Motherland League").
1929 March, 50th birthday, hiding in the suburbs to avoid birthday celebrations. On June 28th, he won the Planck Medal.
1930 is the year of 65438+ February11~1931. On March 4th, Einstein visited the United States for the second time and gave a speech at California Institute of Technology.
1932 Corresponded with Freud in July to discuss the psychological problems of war; Call on the German people to stand up and defend the Weimar Republic and oppose fascism with all their strength.
193365438+1October 30th, the Nazis came to power.
On March 10, I made a statement in Pasadena that I would not return to Germany and set off for Europe the next day.
On March 20th, the Nazis searched his house, and he protested. After that, his property in Germany was confiscated and his works were burned.
1935 In May, he formally applied for permanent residency in the United States in Bermuda. That year, in order to get the Nobel Prize (Peace Prize) awarded to Ausier Tsky, who was imprisoned in a Nazi concentration camp, he ran around. /kloc-0 supported China's "Seven Gentlemen" in March, 937.
1937, with the cooperation of two assistants, he deduced the equation of motion from the gravitational field equation of general relativity, further revealing the unity of time and space, matter and motion, which was a major development of general relativity and the last major achievement Einstein made in scientific creation activities. He never succeeded in the unified field theory. He never gets discouraged and always starts from scratch with confidence. Because he was far away from the mainstream of physics research at that time, he went alone to overcome the problems that could not be solved at that time. So contrary to the situation in the 1920s, he was very isolated in physics in his later years. However, he is still fearless and unswervingly follows his own path. Until the day before his death, he was still in his hospital bed preparing to continue his mathematical calculation of the unified field theory. Einstein, who cares about the fate of all mankind, loves science and humanity. He didn't isolate himself from society because he was immersed in scientific research. He always cared about human civilization and progress and fought bravely for it. He said, "One can only find the meaning of a short and risky life if he devotes himself to society", and he did it himself.
1September, 938, he wrote a letter to future generations after 5,000 years, expressing his dissatisfaction with the present situation of capitalist society.
1On August 2, 939, he wrote to President Roosevelt, suggesting that the United States should pay close attention to atomic energy research and prevent Germany from mastering the atomic bomb first.
1940 telephoned Roosevelt on May 22 to oppose the neutral policy of the United States.
65438+1 October1obtained American citizenship.
May 1943, joined the work of the United States Admiralty as a scientific consultant.
1944, in order to support the anti-fascist war, 1905 manuscript of special relativity was auctioned for $6 million.
1947 continues to make a lot of remarks about world government.
1949, 1 month, he wrote Critical Answers to criticize the criticism of Copenhagen School in the collection Albert Einstein: Philosopher-Scientist.
1949 Einstein wrote an article "Why is socialism? Newspapers. Here, he put forward a view that seems to be correct now! "Planned economy is socialism. The planned economy itself may be accompanied by complete slavery of individuals. The establishment of socialism needs to solve some extremely difficult social and political problems. In view of the high concentration of political power and economic power, how can we prevent administrative personnel from becoming unlimited and arrogant? How to ensure a democratic balance for administrative power while protecting individual rights? "
In February 1950, 13, he made a televised speech against American-made hydrogen bombs. Signed and sealed the will on March 65438, 2008.
195 1 year, he published articles and letters one after another, pointing out that the U.S. policy of armament expansion is a serious obstacle to world peace.
1 952165438+1October,1After the death of Israeli President weismann, the Israeli government asked him to be the second president, but he was rejected.
1954 was denounced as "the enemy of America" by US Senator McCarthy in March.
From 65438 to 0955, Einstein and Russell jointly published the Russell-Einstein Declaration, which opposed nuclear war and called for world peace.
1955 died in the hospital on April 18 1: 25. After a long and difficult exploration of general relativity, Einstein was still not satisfied, so he wanted to extend general relativity to include not only gravitational field, but also electromagnetic field. He believes that this is the third stage of the development of relativity, namely the unified field theory.
Exploration of 1928 to pure mathematics. He tried various methods, but he didn't get any results with real physical significance.

Einstein's contribution
The law of material immortality refers to the immortality of material quality; The law of conservation of energy is about the conservation of energy of matter.
Although these two laws have been discovered one after another, people think that they are two unrelated laws, each of which explains different natural laws. Some people even think that the law of immortality of matter is a chemical law, and the law of conservation of energy is a physical law, belonging to different scientific categories.
Einstein thought that the mass of matter is a measure of inertia and energy is a measure of motion. Energy and mass are not isolated from each other, but are interrelated and inseparable. The change of the mass of the object will change the energy accordingly; And the change of the energy of the object will change the mass accordingly.
In the special theory of relativity, Einstein put forward the famous formula of mass and energy: E = MC 2.
(here e stands for the energy of the object, m stands for the mass of the object, and c stands for the speed of light, that is, 300 thousand kilometers per second. )
According to Einstein's theory, if water with a temperature of 1g of 0℃ is heated to 100℃, the water will absorb 100 calories, and the quality of water will increase accordingly. According to the mass-energy relationship, the mass of 1g water increased by 0.0000465g ..
Einstein's theory was initially opposed by many people, and even some famous physicists at that time expressed doubts about this young man's paper. However, with the development of science, a large number of scientific experiments have proved that Einstein's theory is correct. Einstein has become a world-famous scientist and one of the greatest scientists in the world in the 20th century.
Einstein's formula of mass-energy relationship correctly explains all kinds of nuclear reactions: take helium 4 as an example, its nucleus consists of two protons and two neutrons. In principle, the mass of helium 4 nucleus is equal to the sum of the masses of two protons and two neutrons. In fact, this arithmetic doesn't hold water. The mass of helium nucleus is 0.0302 atomic mass unit less than the sum of the mass of two protons and two neutrons [57]! Why is this? Because when two deuterium [dao] nuclei (each deuterium contains 1 proton and 1 neutron) are polymerized into 1 helium 4 nuclei, a large amount of atomic energy is released. When 1 g helium 4 atom is generated, about 27000000000000 joules of atomic energy are released. Because of this, the mass of helium 4 nucleus decreases.
This example vividly shows that when two deuterons are polymerized into 1 helium 4 nucleus, it seems that the mass is not conserved, that is, the mass of helium 4 nucleus is not equal to the sum of the two deuterons. However, calculated by the formula of mass-energy relationship, the mass lost by helium 4 nucleus is exactly equal to the mass reduced by releasing atomic energy during the reaction!
In this way, Einstein expounded the essence of the law of immortality of matter and the law of conservation of energy from a newer height, pointed out the close relationship between these two laws, and deepened human understanding of nature.
There is no mystery in nature that human beings cannot understand; But the mystery of nature is endless. Man will never fully understand nature, and never fully understand its mystery. Only by never being satisfied can we keep moving forward.
The laws of immortality of matter and conservation of energy are great laws of nature. It comes from objective reality and is tested in it. Over the years, these two laws have stood the test of thousands of times, shining with dazzling light like a gem that can withstand wind and rain.
The law of immortality of matter and the law of conservation of energy have become the cornerstones of modern natural science. At the same time, they also dealt a fatal blow to religious idealism. Because matter can't be produced out of thin air and can't be destroyed out of thin air, no one believes in the anti-scientific fallacy that God created everything and God created the world. In addition, it also eloquently shows that there will never be a perpetual motion machine in the world. It is impossible to get energy from nature without labor.
The law exists objectively. Although people can't "create" laws and "transform" laws, they can find them, master them and make use of them. Now, the declaration of immortality of matter and conservation of energy has been mastered by millions of people. People are using the law of immortality of matter and the law of conservation of energy to conquer, transform and uncover the secrets of nature!
