Book Description
This edition of the private and scientific correspondence of Sir Rudolf Peierls gives a unique insight into the life and work of one of the greatest theoretical physicists of the 20th century. Rudolf Peierls' scientific work contributed to the early developments in quantum mechanics, and he is well known and much appreciated for his contributions to various disciplines, including solid state physics, nuclear physics, and particle physics. As an enthusiastic and devoted teacher, he passed on his knowledge and understanding and inspired the work of collaborators and students alike. As an effective administrator he was responsible, almost single-handedly, for the establishment of an outstanding successful centre of theoretical physics in Birmingham, and later contributed much to theoretical physics in Oxford.A meticulous collector of correspondence, Sir Rudolf left a fascinating collection of letters, in some cases spanning more than seven decades. This collection includes correspondence with his parents, his wife, the Russian-born physicist Genia Kannegieser, life-long friends such as Hans Bethe, and many great physicists, including Wolfgang Pauli, Niels Bohr, Werner Heisenberg, Lev Landau, and George Placzek, to name but a few.This first volume, which covers the years 1922 to 1945, contains much of the early family correspondence, letters exchanged between Rudolf and Genia Peierls before and after their marriage in 1931, correspondence relating to early developments in quantum physics, and interesting material relating to the development of nuclear weapons. The extensive apparatus provides an invaluable background which allows the reader to put the presented documents into their multi-faceted social, political and scientific context.

Materials from the 1950s provide evidence for the significance of the research undertaken by Peierls' group at Birmingham, and for the positive impact of his determined implementation of international exchange on the development of theoretical physics.

Trinity
Author: Frank Close
Publisher: Penguin UK
ISBN: 0241309891
Category : History
Languages : en
Pages : 483
Book Description
'Everything about this story is astounding' Bryan Appleyard, Sunday Times "Trinity" was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. Trinity is now also the extraordinary story of the bomb's metaphorical father, Rudolf Peierls; his intellectual son, the atomic spy, Klaus Fuchs, and the ghosts of the security services in Britain, the USA and USSR. Against the background of pre-war Nazi Germany, the Second World War and the following Cold War, the book traces how Peierls brought Fuchs into his family and his laboratory, only to be betrayed. It describes in unprecedented detail how Fuchs became a spy, his motivations and the information he passed to his Soviet contacts, both in the UK and after he went with Peierls to join the Manhattan Project at Los Alamos in 1944. Frank Close is himself a distinguished nuclear physicist: uniquely, the book explains the science as well as the spying. Fuchs returned to Britain in August 1946 still undetected and became central to the UK's independent effort to develop nuclear weapons. Close describes the febrile atmosphere at Harwell, the nuclear physics laboratory near Oxford, where many of the key players were quartered, and the charged relationships which developed there. He uncovers fresh evidence about the role of the crucial VENONA signals decryptions, and shows how, despite mistakes made by both MI5 and the FBI, the net gradually closed around Fuchs, building an intolerable pressure which finally cracked him. The Soviet Union exploded its first nuclear device in August 1949, far earlier than the US or UK expected. In 1951, the US Congressional Committee on Atomic Espionage concluded, 'Fuchs alone has influenced the safety of more people and accomplished greater damage than any other spy not only in the history of the United States, but in the history of nations'. This book is the most comprehensive account yet published of these events, and of the tragic figure at their centre.

Bruno Touschek's Extraordinary Journey
Author: Giulia Pancheri
Publisher: Springer Nature
ISBN: 3031038266
Category : Science
Languages : en
Pages : 493
Book Description
This book tells the story of a unique scientific and human adventure, following the life and science of Bruno Touschek, an Austrian born physicist, who conceived and built AdA, the first matter-antimatter colliding-beam storage ring, the ancestor of the Large Hadron Collider at CERN where the Higgs Boson was discovered in 2012. Making extensive use of archival sources and personal correspondence, the author offers for the first time a unified history of European efforts to build modern-day particle accelerators, from the dark times of war-ravaged Europe up to the rebuilding of science in Germany, UK, Italy and France through the 1950s and early 1960s. This book, the result of several years of scholarly research work, includes numerous previously unpublished photos as well as original drawings by Bruno Touschek.

George Placzek: A Nuclear Physicist's Odyssey
Author: Ales Gottvald
Publisher: World Scientific
ISBN: 9813236930
Category : Science
Languages : en
Pages : 395
Book Description
This book presents the first detailed biography of George Placzek — an outstanding physicist, a participant in the Manhattan Project who stood at the very inception of nuclear physics and the subsequent development of the nuclear bomb in the course of the WWII. In the 1930s, George Placzek was known as an adventurous person with a sharp sense of humor, a tireless generator of novel physics ideas which he generously shared with his colleagues. Born in Brno (now Czech Republic) into a wealthy Jewish family, he lost all his relatives to Holocaust, casting a tragic shadow on his life.Placzek's scientific career began in the late 1920s when the quantum revolution was almost over, but nuclear physics was still at its infancy. He established personal and scientific relations with the creators of quantum mechanics, such as Heisenberg in Leipzig and Niels Bohr in Copenhagen. In Rome, he worked with Fermi, and in Copenhagen he became a part of Bohr's nuclear physics team which dominated nuclear theory at that time. The scope of Placzek's pilgrimage around world physics centers in the 1930s was unique among his colleagues. In January 1939, George Placzek managed to emigrate from Europe to the US, and became a part of the British Mission within the Manhattan Project. His physical insights were instrumental in advancing from the basic discoveries on nuclear chain reactions to the Trinity experiment, Hiroshima and Nagasaki.This book is a unique compilation of a large number of previously unknown and unpublished documents from private and university archives, police reports, etc. Placzek's correspondence with the leadership of the Hebrew University in 1934, the 1937 NKVD interrogation files of Konrad Weisselberg, recollections of Ella Andriesse as well as the Zurich Police report of 1956 detailing the circumstances of Placzek's death in a Zurich hotel are illuminating as they shed light on poorly known pages of his life.

Driven to Innovate
Author: Ioan Mackenzie James
Publisher: Peter Lang
ISBN: 9781906165222
Category : Art
Languages : en
Pages : 328
Book Description
Ioan James celebrates the extraordinary contribution made by Jewish people in mathematics and physics, from the mathematician Norbert Wiener, the founder of cybernetics, to distinguished nuclear physicist and Nobel Prize-winner Niels Bohr. He tells the life-stories of thirty-five men and women, born in the nineteenth century, who were at the forefront of research in the closely related fields of mathematics and physics, often in the face of various kinds of anti-Semitism. Some were caught up in the trauma of the Nazi accession to power in Germany and the Second World War. Wolfgang Pauli, described as 'greater than Einstein' by his contemporary Max Born, became a German national following the Nazi annexation of Austria in 1938 but was able to escape to the United States for the duration of the war. Already hampered by anti-Semitism in his native Poland, logician and mathematician Alfred Tarski found himself stranded in the USA at the outbreak of war and did not see his wife and sons until the war's end. The Italian mathematician Vito Volterra publicly opposed Mussolini's Fascist regime at considerable personal risk. Others such as George Pólya and Emmy Noether found that their left-wing political beliefs hindered their careers.
