Mysterious objects like quarks and quasars, strange mathematical symbols and complex speculations about the beginnings of the universe-all these make the world of physics seem to be an exotic, even forbidding, realm. Yet everyday things we take for granted, from bicycles to microwave ovens, are the result of the development of this central branch of modern science.
Renowned science authority Dr. Isaac Asimov has taken the basic concepts of physics and grouped them logically into three bestselling volumes.
Motion, Sound and Heat
Light, Magnetism and Electricity
The Electron, Proton and Neutron.
All three are presented in this edition complete and unabridged, allowing the reader to trace the fascinating story of modern physics—the human search for rules that govern and describe the universe.
From Galileo’s refutation of Greek theories which, unchallenged, held sway for over 2,000 years, to modern conjectures about the creation of time, matter and space, this lively and entertaining history enables the general reader to understand the development of physics not only as a series of logical progressions but also as an exiting drama of the human spirit’s quest for knowledge. The solving of one set of problems leads inevitably to the challenge of new questions.
In each of the volumes, Dr. Asimov concentrates on the development of specific concepts and places them against the appropriate historical background. Volume One, Motion, Sound and Heat, traces the theoretical exploration of these concepts from an essentially Newtonian viewpoint. Newton’s great achievement was in synthesizing the laws of motion and energy and indeveloping a unifying theory of universal gravitation. Concepts now considered common knowledge were at the time seen as so far fetched that even Newton himself felt that, although they must obey the natural laws he discovered, «angels» were required to move everything.
The second volume, Light, Magnetism and Electricity, views the development of these concepts from the viewpoint of the 19th century, when much of the theoretical work of physics was being transformed into the practical technology of the Industrial Revolution.
Physics was the intellectual fuel of industrialization. Dr. Asimov also shows how the development of 19th century physics led to the Second Scientific Revolution of Einstein’s Relativity and Plank’s Quantum Theory.
In the final volume, The Electron, Proton and Neutron, the author deals with a central concern of 20th century physics — the description of the infinitesimally small particles and waves that constitute the very fabric of the universe. The quest takes us to the frontiers of physics today where physicists speculate about the birth and boundaries of the universe, instantaneous particle communication and even other dimensions which may describe parallel realities.
Written with a minimum of jargon and mathematical equations, Understanding Physics makes the exotic and forbidding realm accessible and inviting. The reader will find also the human drama behind the quest for knowledge about the universe around us
