Afterheleftschool,hewenttoSwitzerland,wherehegraduatedfromtheuniversitywithadegreeinmathematics.,AlbertEinstein,In 1905, Einstein began to publish a series of papers which shook the whole scientific and intellectual world, and for the theories he established in the papers he won the Nobel Prize for Physics in 1921. Because Einstein was Jewish, when Hitler took over Germany in 1933, he had to leave the country and finally settled in the United States. There he continued his study on the structure of the universe until his death in 1955.,Main contribution,The main contribution,1905 Brownian motion,1905Special relativity,1905Einstein field equation,1905Photoelectric effect,1915GeneralRelativity,1905E=mc2,Bose - Einstein statistics,The Centurys Greatest Minds,The scientific touchstones of the modern agethe Bomb, space travel, electronics, Quantum physicsall bear his imprint.,About the general relativity,In general relativity, time is considered a dimension like height, width and depth, creating a four dimensional universe called space-time. Einstein argued that gravity is really a warping of space-time,with the greatest distortions near the most massive objects. Because light travels in a straight line through the contours of space-time, a light beam will curve where space-time curves, this curving was first measured in 1919,Spirit & philosophy,In his native Germany he became a target for hatred . As a Jew, a liberal, a humanist, an internationalist, he attracted the enmity of rationalist and anti-semites. His was now a powerful voice, widely heard, always attended to , especially after he moved to the U.S. He used it to promote zionism, pacifism, in his secret 1939 letter to Franklin D. Roosevelt, the construction of a uranium bomb.,HE IS A PACIFIST,Meanwhile, like any demigod, he made bits of legend: that he failed math in school (not true). That he opened a book and found an uncashed $1,500 check he had left as a bookmark (maybe-he was absentminded about everyday affairs).That he was careless about socks, collars, slippers that he couldnt even remember his address: 112 Mercer Street in Princeton, where he finally settled.,Life is casual, work is rigorous,He died there in 1955 And after the rest of Einstein had been cremated, his brain remained, soaking for decades in a jar of formaldehyde belonging to Dr. Thomas Harvey. No one had bothered to dissect the brain of Freud, Stravinsky or Joyce, but in the 1980s, bits of Einsteinian gray matter were making the rounds of certain neurobiologists, who thus learned absolutely nothing. It was just a brainthe brain that dreamed a plastic fourth dimension, that banished the ether, that released the pins binding us to absolute space and time, that refused to believe God played dice.,conclusion,Albert Einstein was considered the greatest scientist of the 20th century and one of the greatest of all time.
