A lively collection of Einstein’s groundbreaking scientific correspondence on modern physics with Schrödinger, Planck, and LorentzImagine getting four of the greatest minds of modern physics in a room together to explain and debate the theories and innovations of their day. This is the fascinating experience of reading Letters on Wave Mechanics, the correspondence between Erwin Schrödinger and Max Planck, H.A. Lorentz, and Albert Einstein. These remarkable letters illuminate not only the basis of Schrödinger’s work in wave mechanics, but also how great scientific minds debated and challenged the ever-changing theories of the day and ultimately embraced an elegant solution to the riddles of quantum theory. Their collected correspondence offers insight into both the personalities and professional aspirations that played a part in this theoretical breakthrough.This authorized Philosophical Library ebook features rare photos and never-before-seen documents from the Albert Einstein Archives at the Hebrew University of Jerusalem.

ABOUT Albert Einstein


    Albert Einstein (1879–1955) is among modern history’s greatest and most influential minds. He authored more than 450 scholarly works during his lifetime, and his advancements in science—including the revolutionary Theory of Relativity and E=mc², which described for the first time the relationship between an object’s mass and its energy—have earned him renown as “the father of modern physics.”

    Born in Ulm, in southwest Germany, Einstein moved to Munich with his family as an infant. As a child, Einstein spoke so infrequently that his parents feared he had a learning disability. But despite difficulties with speech, he was consistently a top student and showed an early aptitude for mathematics and physics, which he later studied at the Swiss Federal Institute of Technology in Zurich after renouncing his German citizenship to avoid military service in 1896.

    After graduation, Einstein married his college girlfriend, Mileva Marić, and they had three children. He attended the University of Zurich for his doctorate and worked at the patent office in Bern, a post he left in 1908 for a teaching position at the University of Bern, followed by a number of professorships throughout Europe that ultimately led him back to Germany in 1914. By this time, Einstein had already become recognized throughout the world for his groundbreaking papers on special relativity, the photoelectric effect, and the relationship between energy and matter. He won the Nobel Prize in Physics in 1921.

    In 1933, Einstein escaped Nazi Germany and immigrated to the United States with his second wife, Elsa Löwenthal, whom he had married in 1919. He accepted a position at Princeton University in New Jersey, where he stayed for the remainder of his life. At Princeton, Einstein dedicated himself to finding a unified field theory and played a key role in America’s development of atomic weapons. He also campaigned for civil rights as a member of the NAACP and was an ardent supporter of Israel’s Labor Zionist Movement.

    Still, Einstein maintained a special affinity for his homeland. His connection to all things German and, in particular, to the scientific community in Berlin was probably the reason that throughout his years in America he so strongly valued his relationships with other German-speaking immigrants. He maintained a deep friendship with the founder of Philosophical Library, Dr. Dagobert D. Runes, who, like Einstein, was a humanist, a civil rights pioneer, and an admirer of Baruch Spinoza. Consequently, many of Albert Einstein’s works were published by Philosophical Library.

    At the time of Einstein’s death in 1955, he was universally recognized as one of history’s most brilliant and important scientists.
