In his monumental 1687 work, Philosophiae Naturalis Principia Mathematica, known familiarly as the Principia, Isaac Newton laid out in mathematical terms the principles of time, force, and motion that have guided the development of modern physical science. Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles. This authoritative, modern translation by I. Bernard Cohen and Anne Whitman, the first in more than 285 years, is based on the 1726 edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system. The translation - only edition of this preeminent work is truly accessible for today's scientists, scholars, and students.

This volume presents Professor Cohen's original interpretation of the revolution that marked the beginnings of modern science and set Newtonian science as the model for the highest level of achievement in other branches of science. It shows that Newton developed a special kind of relation between abstract mathematical constructs and the physical systems that we observe in the world around us by means of experiment and critical observation. The heart of the radical Newtonian style is the construction on the mind of a mathematical system that has some features in common with the physical world; this system s then modified when the deductions and conclusions drawn from it are tested against the physical universe. Using this system Newton was able to make his revolutionary innovations in celestial mechanics and, ultimately, create a new physics of central forces and the law of universal gravitation. Building on his analysis of Newton's methodology, Professor Cohen explores the fine structure of revolutionary change and scientific creativity in general. This is done by developing the concept of scientific change as a series of transformations of ecxisting ideas. It is shown that such transformation is characteristic of many aspects of the sciences and that the concept of scientific change by transformation suggests a new way of examining the very nature of scientific creativity.

A Computer Perspective is an illustrated essay on the origins and first lines of development of the computer. The complex network of creative forces and social pressures that have produced the computer is personified here in the creators of instruments of computation, and their machines or tables; the inventors of mathematical or logical concepts and their applications; and the fabricators of practical devices to serve the immediate needs of government, commerce, engineering, and science. The book is based on an exhibition conceived and assembled for International Business Machines (IBM) Corporation. Like the exhibition, it is not a history in the narrow sense of a chronology of concepts and devices. Yet these pages actually display more true history (in relation to the computer) than many more conventional presentations of the development of science and technology.

The book is divided into nine parts Natural Philosophy, Scientific Method, Experimental Procedure, Optics, Rational Mechanics, Systems of the World, Alchemy and Theory of Matter, Theology, and Mathematics. Text and commentary are woven together, enabling readers to concentrate on the aspects of Newton's astoundingly diverse career they prefer. For each part, the editors provide an introductory essay and textual annotation. In addition, the text is amply illustrated.

The General Introduction to the book sketches Newton's life and offers an interpretation of his scientific achievements. The Biographical Register identifies the many people Newton cites in his writings. The Glossary and Glossary of Chemical Terms explicate scientific terms and concepts. Finally, the Selected Bibliography offers suggestions for further readings of and about Newton."

The great historian of science I. B. Cohen explores how numbers have come to assume a leading role in science, in the operations and structure of government, in marketing, and in many other aspects of daily life. Consulting and collecting numbers has been a feature of human affairs since antiquity taxes, head counts for military service but not until the Scientific Revolution in the twelfth century did social numbers such as births, deaths, and marriages begin to be analyzed. Cohen shines a new light on familiar figures such as Thomas Jefferson, Benjamin Franklin, and Charles Dickens; and he reveals Florence Nightingale to be a passionate statistician. Cohen has left us with an engaging and accessible history of numbers, an appreciation of the essential nature of statistics."

Science in the Political Thought of Thomas Jefferson, Benjamin Franklin, John Adams, and James Madison

"Intellectually engaging . . . deftly written" (Boston Globe). . . . "The founding fathers appear in an interesting new light, thanks to Cohen's fresh, not to say iconoclastic, vision."--Kirkus Reviews

Thomas Jefferson was the only president who could read and understand Newton's Principia. Benjamin Franklin is credited with establishing the science of electricity. John Adams had the finest education in science that the new country could provide, including "Pnewmaticks, Hydrostaticks, Mechanicks, Staticks, Opticks." James Madison, chief architect of the Constitution, peppered his Federalist Papers with reference to physics, chemistry, and the life sciences.

For these men science was an integral part of life--including political life. This is the story of their scientific education and of how they employed that knowledge in shaping the political issues of the day, incorporating scientific reasoning into the Constitution. General readers, students of American history, and professional historians alike will profit from reading this engaging presentation of an aspect of American history conspicuously absent from the usual textbooks and popular presentations of the political thought of this crucial period.

I. Bernard Cohen is Victor S. Thomas Professor Emeritus of the History of Science at Harvard University. He lives in Belmont, Massachusetts.

Only a scholar as rich in learning as I. Bernard Cohen could do justice to a theme so subtle and yet so grand. Spanning five centuries and virtually all of scientific endeavor, "Revolution in Science" traces the nuances that differentiate both scientific revolutions and human perceptions of them, weaving threads of detail from physics, mathematics, behaviorism, Freud, atomic physics, and even plate tectonics and molecular biology, into the larger fabric of intellectual history.

How did "revolution," a term from the physical sciences, meaning a turning again and implying permanence and recurrence--the cyclical succession of the seasons, the 'revolutions' of the planets in their orbits--become transformed into an expression for radical change in political and socioeconomic affairs, then become appropriated once again to the sciences?

How have political revolutions--French, American, Bolshevik--and such intellectual forces as Darwinism further modified the concept, from revolution in science as a dramatic break with the past to the idea that science progresses by the slow accumulation of knowledge? And what does each transformation in each historical period tell us about the deep conceptual changes in our image of the scientist and scientific activity?

Cohen's exploration seeks to uncover nothing less than the nature of all scientific revolutions, the stages by which they occur, their time scale, specific criteria for determining whether or not there has been a revolution, and the creative factors in producing a revolutionary new idea. His book is a probing analysis of the history of an idea and one of the most impressive surveys of the history of science ever undertaken.

Benjamin Franklin is well known to most of us, yet his fundamental and wide--ranging contributions to science are still not adequately understood. Until now he has usually been incorrectly regarded as a practical inventor and tinkerer rather than a scientific thinker. He was elected to membership in the elite Royal Society because his experiments and original theory of electricity had made a science of that new subject. His popular lame came from his two lightning experiments the sentry--box experiment and the later and more famous experiment of the kite--which confirmed his theoretical speculations about the identity of electricity and provided a basis for the practical invention of the lightning rod. Franklin advanced the eighteenth-century understanding of all phenomena of electricity and provided a model for experimental science in general.

I. Bernard Cohen, an eminent historian of science and the principal elucidator of Franklin's scientific work, examines his activities in fields ranging from heat to astronomy. He provides masterful accounts of the theoretical background of Franklin's science (especially his study of Newton), the experiments he performed, and their influence throughout Europe as well as the United States. Cohen emphasizes that Franklin's political and diplomatic career cannot be understood apart from his scientific activities, which established his reputation and brought him into contact with leaders of British and European society. A supplement by Samuel J. Edgerton considers Franklin's attempts to improve the design of heating stoves, another practical application that arose from theoretical interests.

This volume will be valuable to all readerswanting to learn more about Franklin and to gain a deeper appreciation of the development of science in America.
