The definitive account of the great Bohr-Einstein debate and its continuing legacyIn 1927, Niels Bohr and Albert Einstein began a debate about the interpretation and meaning of the new quantum theory. This would become one of the most famous debates in the history of science. At stake were an understanding of the purpose, and defense of the integrity, of science. What (if any) limits should we place on our expectations for what science can tell us about physical reality?Our protagonists slowly disappeared from the vanguard of physics, as its centre of gravity shifted from a war-ravaged Continental Europe to a bold, pragmatic, post-war America. What Einstein and Bohr had considered to be matters of the utmost importance were now set aside. Their debate was regarded either as settled in Bohr's favour or as superfluous to real physics.But the debate was not resolved. The problems of interpretation and meaning persisted, at least in the minds of a few stubborn physicists, such as David Bohm and John Bell, who refused to stop asking awkward questions. The Bohr-Einstein debate was rejoined, now with a new set of protagonists, on a small scale at first. Through their efforts, the debate was revealed to be about physics after all. Their questions did indeed have answers that could be found in a laboratory. As quantum entanglement became a real physical phenomenon, whole new disciplines were established, such as quantum computing, teleportation, and cryptography. The efforts of the experimentalists were rewarded with shares in the 2022 Nobel prize in physics.As Quantum Drama reveals, science owes a large debt to those who kept the discussions going against the apathy and indifference of most physicists before definitive experimental inquiries became possible. Although experiment moved the Bohr-Einstein debate to a new level and drew many into foundational research, it has by no means removed or resolved the fundamental question. There will be no Nobel prize for an answer. That will not shut off discussion. Our Drama will continue beyond our telling of it and is unlikely to reach its final scene before science ceases or the world ends.

From the biographies on Galileo and Dorothy Hodgkin to the discussions chronicling the change of science from simply a tool of learning to a major force in society, The Oxford Companion to the History of Modern Science is the most comprehensive one-volume resource on science from 1550 to the present.Along with chemistry, physics, and biology, the major scientific disciplines are represented in this alphabetically arranged work including astrology, ethnology, and zoology, among many others. General concepts such as gender and science and scientific development are explored along with major time periods that had a tremendous impact on the field including the Enlightenment and Globalization (post-World War II). The coverage is not limited to just one geographical area but is worldwide, tracing science from its traditional centres and explaining how non-western societies have modified and contributed to its global arena.Major divisions of thought including Aristotelianism and mechanical philosophy are also covered as well as an examination of science and its relationship to professional practice and the changing face of disciplines and sub-disciplines. Individual institutions such as CERN and the Third World Academy of Science are explored as well as the epistemology and methodology of scientific knowledge, theoretical constructs, information on apparatus and instruments, the social aspects and responsibilities of science, and the innumerable uses of the applied sciences.Over 90 biographies bring these fields to life with the stories behind the great achievements. Among the notable scientists are Linus Pauling, Margaret Mead, Niels Bohr, Albert Einstein, and Edwin Hubble.An excellent overview of the field of science and its development over the past few generations, The Oxford Companion to the History of Modern Science is an essential resource for students, historians, teachers, scientists, doctors, engineers, and anyone with an interest in the many and varied aspects of science.

With over 150 alphabetically arranged entries about key scientists, concepts, discoveries, technological innovations, and learned institutions, the Oxford Guide to Physics and Astronomy traces the history of physics and astronomy from the Renaissance to the present. For students, teachers, historians, scientists, and readers of popular science books such as Galileo's Daughter, this guide deciphers the methods and philosophies of physics and astronomy as well as the historical periods from which they emerged. Meant to serve the lay reader and the professional alike, this book can be turned to for the answer to how scientists learned to measure the speed of light, or consulted for neat, careful summaries of topics as complicated as quantum field theory and as vast as the universe. The entries, each written by a noted scholar and edited by J. L. Heilbron, Professor of History and Vice Chancellor, Emeritus, University of California, Berkeley, reflect the most up-to-date research and discuss the applications of the scientific disciplines to the wider world of religion, law, war, art and literature. No other source on these two branches of science is as informative or as inviting. Thoroughly cross-referenced and accented by dozens of black and white illustrations, the Oxford Guide to Physics and Astronomy is the source to turn to for anyone looking for a quick explanation of alchemy, x-rays and any type of matter or energy in between.

How does the physics we know today - a highly professionalised enterprise, inextricably linked to government and industry - link back to its origins as a liberal art in Ancient Greece? What is the path that leads from the old philosophy of nature and its concern with humankind's place in the universe to modern massive international projects that hunt down fundamental particles and industrial laboratories that manufacture marvels?John Heilbron's fascinating history of physics introduces us to Islamic astronomers and mathematicians, calculating the size of the earth whilst their caliphs conquered much of it; to medieval scholar-theologians investigating light; to Galileo, Copernicus, Kepler, and Newton, measuring, and trying to explain, the universe. We visit the 'House of Wisdom' in 9th-century Baghdad; Europe's first universities; the courts of the Renaissance; the Scientific Revolution and the academies of the 18th century; the increasingly specialised world of 20th and 21st century science. Highlighting the shifting relationship between physics, philosophy, mathematics, and technology -- and the implications for humankind's self-understanding -- Heilbron explores the changing place and purpose of physics in the cultures and societies that have nurtured it over the centuries.

Just over four hundred years ago, in 1610, Galileo published the Siderius nuncius, or Starry Messenger, a 'hurried little masterpiece' in John Heilbron's words. Presenting to the world his remarkable observations using the recently invented telescope - of the craters of the moon, and the satellites of Jupiter, observations that forced changes to perceptions of the perfection of the heavens and the centrality of the Earth - the appearance of the little book is regarded as one of the greatest moments in the history of science. It was also a point of change in the life of Galileo himself, propelling him from professor to prophet. But this is not the biography of a mathematician. Certainly he spent the first half of his career as a professor of mathematics and has been called 'the divine mathematician'. Yet he was no more (or less) a mathematician than he was a musician, artist, writer, philosopher, or gadgeteer. This fresh lively new biography of the 'father of science' paints a rounded picture of Galileo, and places him firmly within the rich texture of late Renaissance Florence, Pisa, and Padua, amid debates on the merits of Ariosto and Tasso, and the geometry of Dante's Inferno - debates in which the young Galileo played an active role. Galileo's character and career followed complex paths, moving from the creative but cautious humanist professor to a 'knight errant, quixotic and fearless', with increasing enemies, and leading ultimately and inevitably to a clash with a pope who was a former friend.
