Biography

American physicist of German origin, Albert Einstein changed by his fundamental theory of relativity, the human conception of time, space and the universe, upsetting scientific and philosophical thought.

"Science without religion is lame; religion without science is blind." Einstein once stated his personal conviction in these terms, then he clarified: "A religious person is a believer in the sense that he has absolutely no doubts about the existence of superpersonal purposes which neither require nor admit any rational basis. " In its existence, it made no room for prayers or worship. Yet he was animated by a deep faith, without a rational basis, that there were still laws of Nature to be discovered. He dedicated his life to their discovery.

Albert Einstein biography

Albert Einstein is often cited as one of the most influential scientists of the 20th century. His work continues to help astronomers study everything from gravitational waves to the orbit of Mercury.

The scientist's equation who helped explain the special relativity E = mc² is famous even among those who do not understand its underlying physics. Einstein is also known for his theory of general relativity (an explanation of gravity), and the photoelectric effect (which explains the behavior of electrons under certain circumstances); his work on the latter won him a Nobel Prize in Physics in 1921.

Einstein also tried unsuccessfully to unify all the forces of the universe into a single theory, or theory of everything, that he was still working on at the time of his death.

Einstein's early years

Einstein was born on March 14, 1879 in Ulm, Germany, a city that today has a population of just over 120,000. There is a small commemorative plaque where his house was located (it was destroyed during WWII). The family moved to Munich soon after his birth, and then to Italy when his father struggled to run his own business. Einstein's father, Hermann, ran an electrochemical plant, and his mother Pauline looked after Albert and his younger sister, Maria.

Einstein will write in his memoirs that two "wonders" deeply marked his early years, according to Hans-Josef Küpper, a specialist in Albert Einstein. Young Einstein encountered his first wonder, a compass at the age of 5: he was mystified that unseen forces could deflect the needle. This would lead him to a lifelong fascination with invisible forces. The second wonder came at the age of 12, when he discovered a geometry book he revered, calling it his "holy book of geometry".

Contrary to popular belief, young Albert was a good student. He excelled in physics and mathematics, but was a more "moderate" student in other subjects, Küpper wrote on his website. However, Einstein rebels against the authoritarian attitude of some of his teachers and drops out of school at 16. He then passed an entrance exam at the Federal Institute of Technology in Zurich, and although his performance in physics and mathematics was excellent, his grades in other areas were poor, and he did not pass the exam. 'exam. The aspiring physicist took additional courses to fill his knowledge gaps. He was admitted to the Swiss Federal Institute of Technology in 1896, and in 1901 he received his teaching diploma in physics and mathematics.

However, Einstein did not find a teaching post and began working in a patent office in Berne in 1901. It was there that, between two analyzes of patent applications, he developed his work on special relativity and d 'other areas of physics which later made him famous.

In 1903, Einstein married Mileva Maric. Their children, Hans Albert and Eduard, were born in 1904 and 1910. Einstein divorced Maric in 1919 and soon after married Elsa Löwenthal. Löwenthal died in 1933.

Highlights of his career

Einstein's career sent him to many countries. He obtained his doctorate at the University of Zurich in 1905, then became professor in Zurich (1909), Prague (1911) and again in Zurich (1912). Then he moved to Berlin to become director of the Emperor Wilhelm Institute of Physics and professor at the University of Berlin (1914). He also becomes a German citizen.

A major validation of Einstein's work took place in 1919, when Sir Arthur Eddington, secretary of the Royal Astronomical Society, led an expedition to Africa that measured the position of stars during a total solar eclipse. The group found that the position of the stars was shifted due to the curvature of light around the sun.

Einstein remained in Germany until 1933, when the date was
