In this richly-illustrated 2004 book the author combines history with real science. Using an original approach he presents the major achievements of twentieth-century physics - for example, relativity, quantum mechanics, atomic and nuclear physics, the invention of the transistor and the laser, superconductivity, binary pulsars, and the Bose-Einstein condensate - each as they emerged as the product of the genius of those physicists whose labours, since 1901, have been crowned with a Nobel Prize. Here, in the form of a year-by-year chronicle, biographies and revealing personal anecdotes help bring to life the main events of the past hundred years. The work of the most famous physicists of the twentieth century - great names, like the Curies, Bohr, Heisenberg, Einstein, Fermi, Feynman, Gell-Mann, Rutherford, and Schrödinger - is presented, often in the words and imagery of the prize-winners themselves.
Felix Bloch was one of the foremost scientists of the 20th century. His work on the theory of metals in 1929 laid the cornerstone for the development of semiconductors and his work on magnetism was crucial for the development of a basic understanding of ferromagnetism. Nuclear Magnetic Resonance, which he discovered in 1946, and for which he shared the Nobel Prize with Edward Purcell in 1952, has become the most important spectroscopic tool in Chemistry. The year 1989 marks the sixtieth year since Bloch's paper on the Theory of Metals. This Symposium celebrated the occasion by gathering a group of distinguished scientists who presented overviews of the past, present and future of several major areas of Physics, Chemistry, Engineering, Computer Science, Biology and Medicine, many of which trace their origins to Bloch's influence.
In this important volume, major events and personalities of 20th century physics are portrayed through recollections and historiographical works of one of the most prominent figures of European science. A former student of Enrico Fermi, and a leading personality of physical research and science policy in postwar Italy, Edoardo Amaldi devoted part of his career to documenting, both as witness and as historian, some significant moments of 20th century science. The focus of the book is on the European scene, ranging from nuclear research in Rome in the 1930s to particle physics at CERN, and includes biographies of physicists such as Ettore Majorana, Bruno Touschek and Fritz Houtermans.Edoardo Amaldi (Carpaneto, 1908 - Roma, 1989) was one of the leading figures in twentieth century Italian science. He was conferred his degree in physics at Rome University in 1929 and played an active role (as a member of the team of young physicists known as ?the boys of via Panisperna?) in the fundamental research on artificial induced radioactivity and the properties of neutrons, which won the group's leader Enrico Fermi the Nobel Prize for physics in 1938. Following Fermi's departure for the United States in 1938 and the disruption of the original group, Amaldi took upon himself the task of reorganising the research in physics in the difficult situation of post-war Italy. His own research went from nuclear physics to cosmic ray physics, elementary particles and, in later years, gravitational waves. Active research was for him always coupled to a direct involvement as a statesman of science and an organiser: he was the leading figure in the establishment of INFN (National Institute for Nuclear Physics) and has played a major role, as spokesman of the Italian scientific community, in the creation of CERN, the large European laboratory for high energy physics. He also actively supported the formation of a similar trans-national joint venture in space science, which gave birth to the European Space Agency. In these and several other scientific organisations, he was often entrusted with directive responsibilities. In his later years, he developed a keen interest in the history of his discipline. This gave rise to a rich production of historiographic material, of which a significant sample is collected in this volume.
The 1952 Nobel physics laureate Felix Bloch (1905-83) was one of the titans of twentieth-century physics. He laid the fundamentals for the theory of solids and has been called the “father of solid-state physics.” His numerous, valuable contributions include the theory of magnetism, measurement of the magnetic moment of the neutron, nuclear magnetic resonance, and the infrared problem in quantum electrodynamics.Statistical mechanics is a crucial subject which explores the understanding of the physical behaviour of many-body systems that create the world around us. Bloch's first-year graduate course at Stanford University was the highlight for several generations of students. Upon his retirement, he worked on a book based on the course. Unfortunately, at the time of his death, the writing was incomplete.This book has been prepared by Professor John Dirk Walecka from Bloch's unfinished masterpiece. It also includes three sets of Bloch's handwritten lecture notes (dating from 1949, 1969 and 1976), and details of lecture notes taken in 1976 by Brian Serot, who gave an invaluable opinion of the course from a student's perspective. All of Bloch's problem sets, some dating back to 1933, have been included.The book is accessible to anyone in the physical sciences at the advanced undergraduate level or the first-year graduate level.
John Stewart Bell (1928-1990) was one of the most important figures in twentieth-century physics, famous for his work on the fundamental aspects of the century's most important theory, quantum mechanics. While the debate over quantum theory between the supremely famous physicists, Albert Einstein and Niels Bohr, appeared to have become sterile in the 1930s, Bell was able to revive it and to make crucial advances - Bell's Theorem or Bell's Inequalities. He was able to demonstrate a contradiction between quantum theory and essential elements of pre-quantum theory - locality and causality. The book gives a non-mathematical account of Bell's relatively impoverished upbringing in Belfast and his education. It describes his major contributions to quantum theory, but also his important work in the physics of accelerators, and nuclear and elementary particle physics.
The 20th Century has been called the Century of Physics. It could be even more appropriate to call it the Century of Solid State Physics. All the technological developments which had changed the world by the end of the century had been based upon previous scientific developments in Solid State Physics.The Braggs, Debye, Bardeen, Landau were certainly at the forefront of all those revolutionary changes.
