Outstanding text by one of the 20th century's foremost physicists dramatically explains how the central laws of physical science evolved, from Pythagoras' discovery of frequency ratios in the 6th century BC to today's research on elementary particles. Includes fascinating biographical data about Galileo, Newton, Huygens, Einstein and others. 136 illustrations.

Here is a lively history of modern physics, as seen through the lives of thirty men and women from the pantheon of physics. William H. Cropper vividly portrays the life and accomplishments of such giants as Galileo and Isaac Newton, Marie Curie and Ernest Rutherford, Albert Einstein and Niels Bohr, right up to contemporary figures such as Richard Feynman, Murray Gell-Mann, and Stephen Hawking. We meet scientists--all geniuses--who could be gregarious, aloof, unpretentious, friendly, dogged, imperious, generous to colleagues or contentious rivals. As Cropper captures their personalities, he also offers vivid portraits of their great moments of discovery, their bitter feuds, their relations with family and friends, their religious beliefs and education. In addition, Cropper has grouped these biographies by discipline--mechanics, thermodynamics, particle physics, and others--each section beginning with a historical overview. Thus in the section on quantum mechanics, readers can see how the work of Max Planck influenced Niels Bohr, and how Bohr in turn influenced Werner Heisenberg. Our understanding of the physical world has increased dramatically in the last four centuries. With Great Physicists, readers can retrace the footsteps of the men and women who led the way.

Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.

Starting with Galileo's experiments with motion, this study of 25 crucial discoveries includes Newton's laws of motion, Chadwick's study of the neutron, Hertz on electromagnetic waves, and more.

Motion is always relative to some thing. Is this thing a concrete body like the earth, is it an abstract space, or is it an imagined frame? Do the laws of physics depend on the choice of reference? It there a choice for which the laws are simplest? Is this choice unique? Is there a physical cause for the choice made? These questions traverse the history of modern physics from Galileo to Einstein. The answers involved Galilean relativity, Newton's absolute space, the purely relational concepts of Descartes, Leibniz, and Mach, and many forgotten uses of relativity principles in mechanics, optics, and electrodynamics - until the relativity theories of Poincaré, Einstein, Minkowksi, and Laue radically redefined space and time to satisfy universal kinds of relativity. Accordingly, this book retraces the emergence of relativity principles in early modern mechanics, documents their constructive use in eighteenth- and nineteenth-century mechanics, optics, and electrodynamics, and gives a well-rooted account of the genesis of special and general relativity in the early twentieth century. As an exercise in long-term history, it demonstrates the connectivity of issues and approaches across several centuries, despite enormous changes in context and culture. As an account of the genesis of relativity theories, it brings unprecedented clarity and fullness by broadening the spectrum of resources on which the principal actors drew.

In his lifetime, Galileo straddled the epochs of the Renaissance and the Scientific Revolution, and it was his work and technological advances that helped usher in a brand new understanding of the solar system and the scientific method. Stephen Hawking himself has asserted, "Galileo, perhaps more than any other single person, was responsible for the birth of modern science." Sir Isaac Newton is widely considered the most influential scientist in history, best known for the discovery of gravity and the subsequent laws of motion that he theorized. Schoolchildren around the world are still taught the famous legend about an apple falling on Newton's head, but that colorful story and the preoccupation with Newton's work in physics tend to make people forget Newton's work in other fields. Using empirical studies, Newton developed theories about light prisms, how matter cools, and even tried studying and calculating the speed of sound. And those are just the sciences; Newton also helped develop several mathematical fields, including calculus. Michael Faraday, an endlessly luminous mind equipped with an unflagging hunger for knowledge, possessed a hunger so ungovernable that not even poverty or social norms could stand in the way of his ambitions. Indeed, it was reportedly Albert Einstein's expertise in the lives of Maxwell and Faraday, as well as his mastery of their work and accomplishments, that landed him his first job at the Swiss Patent Office after months of job-scouring. Moreover, Einstein's admiration for Faraday was so profound that when a friend gifted him a biography of his "hero" for his birthday, Einstein cherished it to the utmost degree. Nikola Tesla was one of history's greatest scientists, and though he is best known for his pioneering work with electricity, the fact that he is mostly remembered solely for that actually does a disservice to his legacy. Born a Serb in the Austrian Empire, Tesla came to the United States and worked in a laboratory for none other than the Wizard of Menlo Park, Thomas Edison. It was through his work on behalf of Edison that Tesla flourished and became a well-known figure in his own right. Max Planck has been remembered as the theoretical physicist whose revolutionary discovery of energy quanta and formulation of fundamental quantum theory allowed for countless others to expand on the knowledge of atomic processes. The immensity of Max Planck's legacy is difficult to condense into mere words. Albert Einstein needs no formal introduction. He is known around the world as one of history's most brilliant geniuses, and one of its most influential scientists. Einstein is often regarded as the father of modern physics, and he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". And though he is best known for his contributions to science with over 300 scientific papers, the witty Einstein also wrote over 150 non-scientific works, many of them infused with his humor. One of the most famous, and important, physicists is Niels Bohr, a world-famous physicist and one of the patriarchs of quantum theory. Given the vibrant, peaceful haven that is Denmark today, it's somewhat ironic that Bohr played an instrumental role in the development of the atomic bomb. Even so, the truth and depth of the matter, much like the self-professed pacifist himself, is far more complex.

Following the style of Galileo's Dialogue on the Two Chief World Systems, and addressed to readers without specialized knowledge in physics and higher mathematics, this book lets us listen in on an imaginary meeting of the scientists who created classical physics and modern relativity.
