Timelines of Discovery in Physics


Book Description

Physics is the fundamental branch of science that developed out of the study of nature and philosophy known, until around the end of the 19th century, as "natural philosophy". Today, physics is ultimately defined as the study of matter, energy and the relationships between them. Physics is, in some senses, the oldest and most basic pure science; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world. The other sciences are generally more limited in their scope and may be considered branches that have split off from physics to become sciences in their own right. Physics today may be divided loosely into classical physics and modern physics.Elements of what became physics were drawn primarily from the fields of astronomy, optics, and mechanics, which were methodologically united through the study of geometry. These mathematical disciplines began in antiquity with the Babylonians and with Hellenistic writers such as Archimedes and Ptolemy. Ancient philosophy, meanwhile - including what was called "physics" - focused on explaining nature through ideas such as Aristotle's four types of "cause". Advances in the knowledge of the laws of nature consisting either of experimental discoveries or theoretical proposals that were confirmed experimentally.This book outlines the discoveries made in the following fields of physics.* Nature timeline (Formation of The Universe)* Timeline of fundamental physics discoveries* Timeline of classical mechanics* Timeline of electromagnetism and classical optics* Timeline of electromagnetic theory* Timeline of thermodynamics* Timeline of states of matter and phase transitions* Timeline of gravitational physics and relativity* Timeline of atomic and subatomic physics* Timeline of particle physics* Timeline of particle discoveries* Timeline of nuclear fusion* Timeline of theoretical physics* Timeline of computational physics* Timeline of cosmological theories* Timeline of black hole physics* Timeline of heat engine technology* Timeline of particle physics technology* Timeline of physical chemistry* Timeline of quantum mechanics* Timeline of quantum computing

Serendipity


Book Description

Many of the things discovered by accident are important in our everyday lives: Teflon, Velcro, nylon, x-rays, penicillin, safety glass, sugar substitutes, and polyethylene and other plastics. And we owe a debt to accident for some of our deepest scientific knowledge, including Newton's theory of gravitation, the Big Bang theory of Creation, and the discovery of DNA. Even the Rosetta Stone, the Dead Sea Scrolls, and the ruins of Pompeii came to light through chance. This book tells the fascinating stories of these and other discoveries and reveals how the inquisitive human mind turns accident into discovery. Written for the layman, yet scientifically accurate, this illuminating collection of anecdotes portrays invention and discovery as quintessentially human acts, due in part to curiosity, perserverance, and luck.




Drawing Physics


Book Description

A physics professor pairs short, elegantly written essays with simple drawings that offer engaging and accessible explanations of 51 key ideas in physics, from triangulation to relativity and beyond Humans have been trying to understand the physical universe since antiquity. Aristotle had one vision (the realm of the celestial spheres is perfect), and Einstein another (all motion is relativistic). Understandings often begin with a drawing, a humble but effective tool of the physicist's craft, part of the tradition of thinking, teaching, and learning passed down through the centuries. Don Lemons, a professor of physics and author of several physics books, pairs his essays with drawings that together convey important concepts from the history of physical science. The essays proceed chronologically, beginning with Thales' discovery of triangulation, the Pythagorean monochord, and Archimedes' explanation of balance. Readers will learn about Leonardo's description of “earthshine” (the ghostly glow between the horns of a crescent moon), Kepler's laws of planetary motion, and Newton's cradle (suspended steel balls demonstrating by their collisions that for every action there is always an equal and opposite reaction). Lemons reaches the 20th and 21st centuries with pieces on the photoelectric effect, the hydrogen atom, general relativity, the global greenhouse effect, Higgs boson, and more. The essays also place the science of the drawings in historical context—describing Galileo's conflict with the Roman Catholic Church over his teaching that the sun is the center of the universe, the link between the discovery of electrical phenomena and the romanticism of William Wordsworth, and the shadow cast by the Great War over Einstein's discovery of relativity.




The Discovery of Global Warming


Book Description

In 2001 a panel representing virtually all the world's governments and climate scientists announced that they had reached a consensus: the world was warming at a rate without precedent during at least the last ten millennia, and that warming was caused by the buildup of greenhouse gases from human activity. The consensus itself was at least a century in the making. The story of how scientists reached their conclusion--by way of unexpected twists and turns and in the face of formidable intellectual, financial, and political obstacles--is told for the first time in The Discovery of Global Warming. Spencer R. Weart lucidly explains the emerging science, introduces us to the major players, and shows us how the Earth's irreducibly complicated climate system was mirrored by the global scientific community that studied it. Unlike familiar tales of Science Triumphant, this book portrays scientists working on bits and pieces of a topic so complex that they could never achieve full certainty--yet so important to human survival that provisional answers were essential. Weart unsparingly depicts the conflicts and mistakes, and how they sometimes led to fruitful results. His book reminds us that scientists do not work in isolation, but interact in crucial ways with the political system and with the general public. The book not only reveals the history of global warming, but also analyzes the nature of modern scientific work as it confronts the most difficult questions about the Earth's future. Table of Contents: Preface 1. How Could Climate Change? 2. Discovering a Possibility 3. A Delicate System 4. A Visible Threat 5. Public Warnings 6. The Erratic Beast 7. Breaking into Politics 8. The Discovery Confirmed Reflections Milestones Notes Further Reading Index Reviews of this book: A soberly written synthesis of science and politics. --Gilbert Taylor, Booklist Reviews of this book: Charting the evolution and confirmation of the theory [of global warming], Spencer R. Weart, director of the Center for the History of Physics of the American Institute of Physics, dissects the interwoven threads of research and reveals the political and societal subtexts that colored scientists' views and the public reception their work received. --Andrew C. Revkin, New York Times Book Review Reviews of this book: It took a century for scientists to agree that gases produced by human activity were causing the world to warm up. Now, in an engaging book that reads like a detective story, physicist Weart reports the history of global warming theory, including the internal conflicts plaguing the research community and the role government has had in promoting climate studies. --Publishers Weekly Reviews of this book: It is almost two centuries since the French mathematician Jean Baptiste Fourier discovered that the Earth was far warmer than it had any right to be, given its distance from the Sun...Spencer Weart's book about how Fourier's initially inconsequential discovery finally triggered urgent debate about the future habitability of the Earth is lucid, painstaking and commendably brief, packing everything into 200 pages. --Fred Pearce, The Independent Reviews of this book: [The Discovery of Global Warming] is a well-written, well-researched and well-balanced account of the issues involved...This is not a sermon for the faithful, or verses from Revelation for the evangelicals, but a serious summary for those who like reasoned argument. Read it--and be converted. --John Emsley, Times Literary Supplement Reviews of this book: This is a terrific book...Perhaps the finest compliment I could give this book is to report that I intend to use it instead of my own book...for my climate class. The Discovery of Global Warming is more up-to-date, better balanced historically, beautifully written and, not least important, short and to the point. I think the [Intergovernmental Panel on Climate Change] needs to enlist a few good historians like Weart for its next assessment. --Stephen H. Schneider, Nature Reviews of this book: This short, well-written book by a science historian at the American Institute of Physics adds a serious voice to the overheated debate about global warming and would serve as a great starting point for anyone who wants to better understand the issue. --Maureen Christie, American Scientist Reviews of this book: I was very pleasantly surprised to find that Spencer Weart's account provides much valuable and interesting material about how the discipline developed--not just from the perspective of climate science but also within the context of the field's relation to other scientific disciplines, the media, political trends, and even 20th-century history (particularly the Cold War). In addition, Weart has done a valuable service by recording for posterity background information on some of the key discoveries and historical figures who contributed to our present understanding of the global warming problem. --Thomas J. Crowley, Science Reviews of this book: Weart has done us all a service by bringing the discovery of global warming into a short, compendious and persuasive book for a general readership. He is especially strong on the early days and the scientific background. --Crispin Tickell, Times Higher Education Supplement A Capricious Beast Ever since the days when he had trudged around fossil lake basins in Nevada for his doctoral thesis, Wally Broecker had been interested in sudden climate shifts. The reported sudden jumps of CO2 in Greenland ice cores stimulated him to put this interest into conjunction with his oceanographic interests. The result was a surprising and important calculation. The key was what Broecker later described as a "great conveyor belt'"of seawater carrying heat northward. . . . The energy carried to the neighborhood of Iceland was "staggering," Broecker realized, nearly a third as much as the Sun sheds upon the entire North Atlantic. If something were to shut down the conveyor, climate would change across much of the Northern Hemisphere' There was reason to believe a shutdown could happen swiftly. In many regions the consequences for climate would be spectacular. Broecker was foremost in taking this disagreeable news to the public. In 1987 he wrote that we had been treating the greenhouse effect as a 'cocktail hour curiosity,' but now 'we must view it as a threat to human beings and wildlife.' The climate system was a capricious beast, he said, and we were poking it with a sharp stick. I found the book enjoyable, thoughtful, and an excellent introduction to the history of what may be one of the most important subjects of the next one hundred years. --Clark Miller, University of Wisconsin The Discovery of Global Warming raises important scientific issues and topics and includes essential detail. Readers should be able to follow the discussion and emerge at the end with a good understanding of how scientists have developed a consensus on global warming, what it is, and what issues now face human society. --Thomas R. Dunlap, Texas A&M University




Aristotle's Physics


Book Description

Aristotle's Physics is one of the least studied "great books"--physics has come to mean something entirely different than Aristotle's inquiry into nature, and stereotyped Medieval interpretations have buried the original text. Sach's translation is really the only one that I know of that attempts to take the reader back to the text itself. -- Leon Cass, University of Chicago
