Albert Einstein
Introduction It is one of the main foundations of modern physics. Einstein's many scientific breakthroughs changed the way people view the universe and how it works.
Einstein passed away on April 18, 1955. Today is the 66th anniversary of Einstein's death.
Eight cards have compiled some unknown facts about Einstein, which may let you know a different Einstein.
1. Einstein was born with a head deformity
When Einstein was born in 1879, his head was deformed and his body was severely overweight. His parents were very afraid that he would become disabled. When his grandmother saw him for the first time, she exclaimed " he is too fat! "
. Worry, luckily his head started to return to normal after a few weeks.
2. He spoke very late
One of the most interesting things about Einstein was,He didn't speak until he was four years old, which may make you have a completely different expectation of one of the most famous geniuses in the world.
Later, the social theorist Thomas Sowell even used the term " Einstein syndrome " to describe smart children who spoke later.
Young Einstein
3. Einstein does not like to wear socks
One of Einstein's many weird habits is that he does not like to wear socks. He even took pride in not wearing socks. When Einstein was young, he discovered that whenever he wears socks, his big toe would always pierce the socks, so he never wears socks anymore.
4. Einstein actually did very well in mathematics when he was a child A true story.
In fact, he was very good in mathematics and physics when he was very young. In one summer, he learned Euclidean geometry and algebra.
5. Einstein gave up his nationality at the age of 16 and became a stateless person
Einstein became a citizen of the German Empire after he was born.However, when he was 16 years old, with the consent of his father, he gave up his German citizenship to avoid military service.
Therefore, Einstein had been a stateless person for five years before he became a Swiss citizen. In the end, he maintained Swiss citizenship all his life.
6. Einstein loves music
Einstein is a music lover. He is passionate about music and even said that he often thinks about music. If he is not a physicist, he might become a musician.
His mother asked him to learn the violin when he was 5 years old, but he didn't like it at that time. However, at the age of 13, he heard Mozart's work and became interested in music. Since then, music has played a pivotal role in Einstein's life, and it is said that he would cheer up his spirits by playing the violin.
7. He likes sailing, but he is not good at sailing
Einstein was a student in Zurich, Switzerland when he first sailed. This is another lifelong hobby of his. He often thinks by going to sea. Usually, he will sail aimlessly in the sea for several hours a day.
However, this famous scientist is not good at sailing. Even in his later years, he often got lost or capsized. In addition, because he didn't know how to swim, Einstein often needed other people to rescue him.
8. After obtaining the teaching diploma, he worked hard to find a job
He spent about two years trying to find a teaching job, but a genius like him could not find a job.
He finally found a job as a patent examiner at the Federal Intellectual Property Office of Berne, where Einstein worked for the patent office for seven years.
9.1905 was Einstein’s "miracle year"
1905 was a great year for Albert Einstein’s 9span. "The Miracle Year" . That year, he completed the thesis and received his doctorate. He also published four major works, which subsequently set off a revolution in modern physics.
All these papers have changed the way scientists observe matter, space and time. What is shocking is that he was only 26 years old in 1905.
10. Einstein slept about 10 hours a day
As we all know, sleep is necessary to keep the brain functioning effectively, and even Einstein attached great importance to sleep. According to reports, he sleeps 10 hours a day.
11. He co-invented the Einstein refrigerator
In addition to being a scientist, Einstein was also an inventor. With his students,He invented the Einstein refrigerator, which was patented in 1930.
This refrigerator does not use Freon and does not have any moving parts. Although it does not make noise, is durable and inexpensive, its energy efficiency is not as good as a typical refrigerator, and it ultimately failed to continue to be promoted commercially.
12. Einstein once proposed a more effective wing shape, but his design failed
Einstein was also very interested in the aviation industry, but in that field, He is not a genius.
In 1916, he wrote a scientific paper and proposed a new aircraft wing design. He wrote the proposal to improve the lift of the aircraft, but when the engineer tested his design on the wing of a conventional aircraft, the lift of the conventional wing was better than Einstein's design.
13. He stayed in the United States because he was a target of the Nazis
Initially, Einstein went to the United States for a two-month work trip and placed his second Let his wife Elsa with her. When he was in the United States, the Nazi movement arose in Germany, and it was very targeted at Einstein's theories and ideas. Nazi scientists even condemned Einstein's theory of relativity and called it "Jewish science".
Einstein even had a bounty on his head. In 1933, when Einstein was in the United States, Adolf Hitler also became the chancellor of Germany. Increasing tensions and anti-Semitism prompted him to realize that because of his Jewish ancestry, he could not return to Germany.
So far Einstein became a refugee, and finally applied for US citizenship in 1935, and officially became a US citizen in 1940.
14. He helped save thousands of Jewish scientists
During the Nazi rule, Einstein and Winston Churchill waited for _strong7 spanstrong6 . The leaders communicated. In his letter, Einstein persuaded leaders to find Jewish scientists in Germany and hire them in their respective countries. As a result, this move allowed Einstein to help save thousands of lives.
15. He was a civil rights activist
Einstein was a civil rights activist who opposed war and racism. As a Jewish scientist in the heyday of German anti-Semitism , he is well aware of the injustices in society. He advocated civil rights on countless occasions and sympathized with people who suffered discrimination, especially in the United States.
Einstein witnessed the widespread racial discrimination in the United States,Especially racial discrimination against African Americans. In his speech at Lincoln University, he called racism a "disease" and publicly opposed racism.
16. Although he was indirectly involved in nuclear war, he advocated against nuclear war
After the scientific breakthrough in Germany during World War II, Einstein realized that the Nazis possessed nuclear weapons. The necessary technology. Then, Einstein wrote a letter to Leo Szilard, warning US President Franklin Roosevelt of the possibility of a nuclear war.
His letter with President Roosevelt eventually led to the launch of " Manhattan Project" . Einstein was a pacifist and champion of anti-war, so he later regretted recommending to Roosevelt to make an atomic bomb. And openly advocate against nuclear war.
17. The FBI has monitored Einstein for decades
Because of his reputation as a famous scientist and social activist, the Federal Bureau of Investigation (FBI) pays close attention to this German-born physics The behavior of the scientist. Since 1932, the FBI has been secretly monitoring Einstein because of his ties to various peace and socialist organizations.
They suspected that the scientist was a communist, and FBI Director Edgar Hoover even wanted to deport Einstein. When Einstein died,The FBI's surveillance archive of Einstein is 1,427 pages long.
18. Israeli Prime Minister asked him to be president, but he refused
Stan was not a citizen of Israel, but he was not a citizen of Israel. And support the establishment of a Jewish homeland in Palestine.
In 1952, Israel's first president, Jam Weizmann, died during his tenure. In order to replace him, the Israeli Prime Minister asked Einstein to assume the post of president. This proposal impressed Einstein, but in the end he did not accept it.
19. His first wife was also an excellent physicist
Einstein's first wife Maric was also a physicist and mathematician. While Einstein was still working hard to obtain his teaching diploma, Maric was the only woman in their class. At that time, higher academic institutions were still reluctant to accept women, and there were many restrictions on enrolling women.
Einstein and Maric became friends, their friendship eventually turned into love, and finally got married in 1903.
However, their marriage had many problems. Einstein's demanding demands on his wife made their married life very unstable. The two divorced in 1919. In order to help take care of his son after the divorce, Einstein gave Maric the bonus he received from the Nobel Prize in 1921.
20. He may never have seen his first child
The correspondence between Einstein and Maric shows,They had a daughter one year before their marriage (1902). Marić gave birth to her in Novi Sad in Serbia and lives with her parents.
When Maric returned to Switzerland, she did not take her daughter with her. Some data indicate that she died of scarlet fever in the baby, while other data speculate that the girl had been adopted by others.
Einstein may never have seen his daughter.
21. Einstein’s second son suffers from schizophrenia
In addition to the first daughter, Einstein and Maric also have two sons, Hans Eber. Te and Edward. 20-year-old Edward Einstein suffered from neurasthenia while studying to become a psychiatrist. The doctor diagnosed him as having schizophrenia. He has been living in the Zurich Psychiatric Clinic since his mother's death.
Einstein often kept in touch with Edward. Edward called Einstein " Tete " (meaning "petite").
22. Einstein's second wife was his cousin
After Einstein divorced Maric, Einstein married Elsa Einstein second. Their mother is a sister, and their father is a cousin. They began to fall in love in 1912, when Einstein and his first wife had not yet divorced.
The two married on June 2, 1919,About three and a half months after Einstein's divorce.
Einstein and Elsa had no children of their own.
23. His achievements in photoelectric effect won him the Nobel Prize in Physics in 1921
=mc 2 and span6 relativity Famous, but he did not win the Nobel Prize for it. His work in the photoelectric effect earned Einstein the Nobel Prize in Physics in 1921.
Although he did not discover such a phenomenon, his interpretation of the law of the photoelectric effect greatly affected the understanding of light and its properties by physicists.
24. Robert Millican conducted experiments to prove that Einstein's theory is not valid, but he finally confirmed Einstein's view
Robert Milli, one of America’s top scientists Ken doubted Einstein's view that light exists in the form of particles and waves.
Milliken questioned particle theory, because most scientific papers prove that light exists in the form of waves. In order to oppose Einstein's theory, Milliken spent ten years experimenting with light.
His experimental results finally confirmed Einstein's theory. Milliken also won the Nobel Prize in Physics in 1923 for his research on fundamental charges and photoelectric effects.
25. Einstein predicted the fifth state of matter,Bose-Einstein (Bose-Einstein) condensate
You may have heard of the four common states of matter, namely solid, liquid, gas and plasma . However, there are other lesser-known states of matter, such as the Bose-Einstein condensate.
Between 1924 and 1925, Einstein and Satyandra Nas Pose predicted this so-called "span9span fifth state of matter ". The temperature is close to absolute zero (-459.67°F, -273.15°C).
26. The photo of Einstein sticking out his tongue was taken on his 72nd birthday. This photo was taken on March 14, 1951, which is Einstein's 72nd birthday.
United News International (UPI) photographer Arthur Sass initially wanted Einstein to smile at the camera. However, that day Einstein decided to stick out his tongue.
Einstein liked this photo and asked UPI to send him 9 copies for personal use. He signed one of them for the reporter. In 2009, the signed photo was sold for $74,324 .
27. He died of aneurysm in 1955 from aneurysm
aortic aneurysm (the largest internal bleeding in the abdomen caused by Einstein's abdominal aortic hemorrhage). The doctor could have extended his life, but Einstein refused the operation.
The scientist said: " I want to leave when I want to leave. It is tasteless to artificially extend my life. I have done my duty, and now it’s time to go. I will do it gracefully. This point. ”
Einstein died on April 18, 1955 at the Princeton Medical Center of the University of Pennsylvania in New Jersey. The talented physicist died at the age of 76 and reportedly worked until a few hours before his death.
28. Thomas Stolz Harvey stole Einstein's brain
After Einstein died in 1955, the pathologist Thomas Stolz Harvey Responsible for autopsy. Harvey dissected Einstein's brain and eyes without the permission of Einstein's family, hoping that neuroscientists could figure out what makes Einstein so smart.
He saved the brain and cut it into 170 pieces, and then selected some parts for neuroscientists and pathologists to study. When Einstein's family learned of this, they finally allowed him to continue his research.
Research on Einstein's brain shows that his brain size and weight are within the normal range. However, there are some differences compared with the normal brain. For example, the area of the brain responsible for spatial and digital processing is larger than usual. Some studies have also shown that compared with other male brains, there are more glial cells in his brain. These cells are responsible for brain nutrition and the formation of myelin, which contributes to faster electrical transmission in neurons.
29. His last words are still a mystery
Einstein's last words will always be a mystery in unprofessional translation. At his last moment, he murmured a few words in German. Unfortunately, the attending nurse did not speak German, nor did he understand the last words of this great scientist.
30. Einstein has a lot of popular quotations, but in fact many of them are not what he said
Einstein was a smart man, and his works are still in science and history books. It resonates with readers. Although his last words are a mystery, many of his words will be regarded as famous quotes by later generations. However, many sentences related to his name did not actually come from him.
The above are 30 unknown facts about Einstein. Hopefully, you can have more different understanding of this great scientist.
