A classic collection of correspondence between two Nobel Prize winners, The Born-Einstein Letters , is also highly topical: scientists continue to struggle with quantum physics, their role in wartime and the public's misunderstanding.

In 1903, despite the vehement objections of his parents, Albert Einstein married Mileva Maric, the companion, colleague, and confidante whose influence on his most creative years has given rise to much speculation. Beginning in 1897, after Einstein and Maric met as students at the Swiss Federal Polytechnic, and ending shortly after their marriage, these fifty-four love letters offer a rare glimpse into Einstein's relationship with his first wife while shedding light on his intellectual development in the period before the annus mirabilis of 1905. Unlike the picture of Einstein the lone, isolated thinker of Princeton, he appears here both as the burgeoning enfant terrible of science and as an amorous young man beset, along with his fiance, by financial and personal struggles--among them the illegitimate birth of their daughter, whose existence is known only by these letters. Describing his conflicts with professors and other scientists, his arguments with his mother over Maric, and his difficulty obtaining an academic position after graduation, the letters enable us to reconstruct the youthful Einstein with an unprecedented immediacy. His love for Maric, whom he describes as "a creature who is my equal, and who is as strong and independent as I am," brings forth his serious as well as playful, often theatrical nature. After their marriage, however, Maric becomes less his intellectual companion, and, failing to acquire a teaching certificate, she subordinates her professional goals to his. In the final letters Einstein has obtained a position at the Swiss Patent Office and mentions their daughter one last time to his wife in Hungary, where she is assumed to have placed the girl in the care of relatives. Informative, entertaining, and often very moving, this collection of letters captures for scientists and general readers alike a little known yet crucial period in Einstein's life.

We are often amazed by the curiosity of children and the questions they ask. And letters to and from children are always appealing, especially so when they are written to someone famous. In Dear professor Einstein, Alice Calaprice has gathered a delightful and charming collection of more than sixty letters from children to Albert Einstein. Einstein could not respond to every letter written to him, but the responses he did find the time to write reveal the intimate human side of the great public persona, a man who, though he spent his days contemplating mathematics and physics, was very fond of children and enjoyed being in their company. Whether the children wrote to Einstein for class projects, out of curiosity, or because of prodding from a parent, their letters are amusing, touching, and sometimes quite precocious. Enhancing this correspondence are numerous splendid photographs showing Einstein amid children, wearing an Indian headdress, carrying a puppet of himself, and donning fuzzy slippers, among many other wonderful pictures. This book is complete with a foreword by Einstein's granddaughter Evelyn, a biography and chronology of Einstein's life, and an essay by Einstein scholar Robert Schulmann on the great scientist's educational philosophy.

Published here in the original German and French, along with an English translation, the correspondence between Albert Einstein and Elie Cartan includes letters written between 1929 and 1932, after which time Einstein abandoned his unified field theory based on absolute parallelism. Originally published in 1979. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
