Although Einstein himself did not play a direct role in the development of the atomic bomb, he later expressed regret about signing the letter to Roosevelt, and urged that all nuclear weapons be transferred into the control of the United Nations.
In the later Cold War years, Einstein lobbied, along with Albert Schweitzer and Bertrand Russell, to stop all nuclear testing and future bombs. In politics, he was a socialist Zionist who supported the creation of a Jewish national homeland in the British mandate of Palestine, and he raised money for Zionist organizations and was in part responsible for the formation of the International Rescue Committee. In a article entitled "Why Socialism?
He was a member of several civil rights groups, and was sympathetic to the notion of vegetarianism, adopting a strict vegetarian diet later in life. The family practised no formal religion in their home and Einstein did not want his children to receive any form of religious instruction. Einstein began to suffer from ill health in , and eventually died of an aortic aneurysm on 18 April in Princeton Hospital in New Jersey at the age of 76, having continued to work, both on physics and on his civil rights and political concerns, until the day he died, his search for a "theory of everything" still unrealized.

How far is it to space, the Moon, the Sun, the stars, etc? How many stars are there?
How does the Sun shine? What different types of stars are there? What is the human body and the Earth, the Sun, the Universe made of? What if the history of the universe were squeezed into the period of one year? What are the coldest and the hottest objects in the universe? What is the electromagnetic spectrum? Astronomer Edwin Hubble deduced that we indeed inhabit an expanding universe, with the two scientists meeting at the Mount Wilson Observatory near Los Angeles in By November , Einstein completed the general theory of relativity.
Einstein considered this theory the culmination of his life research. Einstein's assertions were affirmed via observations and measurements by British astronomers Sir Frank Dyson and Sir Arthur Eddington during the solar eclipse, and thus a global science icon was born.
This equation suggested that tiny particles of matter could be converted into huge amounts of energy, a discovery that heralded atomic power. Famed quantum theorist Max Planck backed up the assertions of Einstein, who thus became a star of the lecture circuit and academia, taking on various positions before becoming director of the Kaiser Wilhelm Institute for Physics today is known as the Max Planck Institute for Physics from to In , readers were allowed a glimpse into some of the unfiltered private thoughts of Einstein as a young man with the publication of The Travel Diaries of Albert Einstein: The Far East, Palestine, and Spain, The young scientist started a sea journey to Japan in Marseilles, France, in autumn of , accompanied by his second wife Elsa.
The couple returned to Germany via Palestine and Spain in March The Travel Diaries contained unflattering analyses of the people he came across, including the Chinese and Sri Lankans, a surprise coming from a man known for vehemently denouncing racism in his later years.
In an entry for November , Einstein refers to residents of Hong Kong as "industrious, filthy, lethargic people Even the children are spiritless and look lethargic.
It would be a pity if these Chinese supplant all other races. At the time the Nazis, led by Adolf Hitler , were gaining prominence with violent propaganda and vitriol in an impoverished post- World War I Germany. The Nazi Party influenced other scientists to label Einstein's work "Jewish physics.
Meanwhile, other European scientists also left regions threatened by Germany and immigrated to the U. After moving, Einstein never went back to his native land. It was at Princeton that Einstein would spend the rest of his life working on a unified field theory—an all-embracing paradigm meant to unify the varied laws of physics.
Not long after he began his career at Princeton, Einstein expressed an appreciation for American "meritocracy" and the opportunities people had for free thought, a stark contrast to his own experiences coming of age.
In , Einstein was granted permanent residency in his adopted country and became an American citizen five years later. During World War II , he worked on Navy-based weapons systems and made big monetary donations to the military by auctioning off manuscripts worth millions.
Roosevelt to alert him of the possibility of a Nazi bomb and to galvanize the United States to create its own nuclear weapons. The U. Einstein was also the recipient of much scrutiny and major distrust from FBI director J. Edgar Hoover. After learning of the bombing of Hiroshima , Japan, Einstein became a major player in efforts to curtail usage of the a-bomb.
The following year he and Szilard founded the Emergency Committee of Atomic Scientists, and in , via an essay for The Atlantic Monthly , Einstein espoused working with the United Nations to maintain nuclear weapons as a deterrent to conflict. Du Bois as well as performing artist Paul Robeson and campaigned for civil rights, calling racism a "disease" in a Lincoln University speech. After World War II, Einstein continued to work on his unified field theory and key aspects of his general theory of relativity, including time travel, wormholes, black holes, and the origins of the universe.
However, he felt isolated in his endeavors since the majority of his colleagues had begun focusing their attention on quantum theory. In the last decade of his life, Einstein, who had always seen himself as a loner, withdrew even further from any sort of spotlight, preferring to stay close to Princeton and immerse himself in processing ideas with colleagues.
The previous day, while working on a speech to honor Israel's seventh anniversary, Einstein suffered an abdominal aortic aneurysm. In , he arrived at the University of Berlin, where he was made director of the Kaiser Wilhelm Institute for Physics. In , Einstein published the general theory of relativity, which he considered his masterwork.
This theory found that gravity, as well as motion, can affect time and space. In , two expeditions sent to perform experiments during a solar eclipse found that light rays from distant stars were deflected or bent by the gravity of the sun in just the way Einstein had predicted. In , he won the Nobel Prize for his work on the photoelectric effect, as his work on relativity remained controversial at the time. Einstein soon began building on his theories to form a new science of cosmology, which held that the universe was dynamic instead of static, and was capable of expanding and contracting.
A longtime pacifist and a Jew, Einstein became the target of hostility in Weimar Germany, where many citizens were suffering plummeting economic fortunes in the aftermath of defeat in the Great War.
In December , a month before Adolf Hitler became chancellor of Germany, Einstein made the decision to emigrate to the United States, where he took a position at the newly founded Institute for Advanced Study in Princeton, New Jersey. He would never again enter the country of his birth. In the process, Einstein became increasingly isolated from many of his colleagues, who were focused mainly on the quantum theory and its implications, rather than on relativity.
Roosevelt advising him to approve funding for the development of uranium before Germany could gain the upper hand. Einstein, who became a U. Throughout the last years of his life, Einstein continued his quest for a unified field theory. Though he published an article on the theory in Scientific American in , it remained unfinished when he died, of an aortic aneurysm, five years later.
