The Einstein manuscript with the theory that tried to explain the whole universe comes to light | Science

Exhibition of manuscripts by Albert Einstein at the Hebrew University of Jerusalem.

Unknown manuscripts with mathematical notes and an unpublished text of Albert Einstein about the theory with which he tried to explain the whole universe are exhibited from this Wednesday in the Hebrew University of Jerusalem, which the scientist of German origin helped to found. Those responsible for the most prestigious campus in Israel, custodians of the archive from the father of the theory of relativity, they have been brought to light on the occasion of the 140th anniversary of his birth after having acquired them from a collector in North Carolina (USA). It's about investigations and written among which the appendix to a study presented before the Prussian Academy of Science in 1930 on the theory of the unified field stands out, for which Einstein intended to prove that gravity and electromagnetism are manifestations of the same field of force.

The attempts of the Nobel Prize in Physics (1921) to establish a great hypothesis that he explained the whole universe, to which he devoted the last three decades of his life, were unsuccessful. "The scientific connections of their calculations are not yet clear," says a spokeswoman for the Hebrew University, "But they are part of their work to integrate all the forces of nature into a single theory". In three letters written in 1916, however, he anticipated studies on the absorption and emission of light by atoms. A "glorious idea", according to his own words, that would later lay the foundations of laser technology.

The 110 manuscripts in German that now show the Albert Einstein Archive, most of which were not known by the public, are added to the more than 8,000 articles and objects bequeathed by the scientist who revolutionized physics. "These documents reflect how his thinking worked and the way he worked," the professor told Reuters. Hanoch Gutfreund, former director of the Hebrew University. "The summaries of his notes show that when an idea assailed him, he would immediately study it and analyze its consequences."

Academic works, medals and official diplomas share space with photographs and private letters. In the current sample of Jerusalem there are several examples of this personal correspondence that help to better understand the human and political profile of its author.

In a premonitory missive written after the death of his youthful friend, the Swiss engineer Michele Basso, he addressed his relatives in Geneva: "He has now left this strange world, a little before me. This has no meaning. People who, like the two of us, believe in physics know that discerning between the past, the present and the future is just an obsessive illusion. " Einstein died on April 18, 1955, a month after the funeral that he was his fellow student at the Polytechnic Institute in Zurich.

"More than 50 years of inquiries have not helped me to approach the unknowns that surround the particles of light," he reflected aloud in another of his letters about the quantum nature of light. "Now any fool thinks he has the answer, but he's just fooling himself."

Nationalized Swiss, Einstein left Germany in 1932 shortly before the rise of Nazism to power and settled in the United States, a country that granted him citizenship. Shortly after receiving the Nobel Prize, he visited the Palestine under British mandate in an international tour, but did not travel to Israel, founded in 1948, although his then leader, Prime Minister David Ben Gurion, offered him the presidency of the Jewish state. Fulfilled at age 73, Einstein declined the offer of the position.

In 1935 he wrote to his son Hans Albert, who at that time still lived in Switzerland, to express his concern at the danger of a new war in Europe. "I read with a point of concern about the rise of movements in Switzerland sponsored by bandits [nazis] German But I think that even in Germany things are waiting to change slowly. Let's hope there is no other war in Europe, "read the letter now exposed in Jerusalem. His political predictions turned out to be more inaccurate than his scientific theories.
