Subtle is the Lord: The Science and the Life of Albert Einstein
"A monument to sound scholarship and graceful style....Accurate, witty and clear as brook water, it is a work against which future scientific biographies will be measured."--The New York Times Book Review

"A marvelous new biography....Pais demonstrates an astute understanding of Einstein's discoveries....The finest Einstein biography yet published."--Science Digest

"A delightful and instructive book, perhaps the most sensitive and valuable scientific biography of Albert Einstein that has been published....Pais exhibits delicacy and sensitive judgment and succeeds in projecting an image that does justice to Einstein, the human being, and conveys the enormous appeal that Einstein had on those privileged to know him. All told, this is a fine book which will be a valuable addition to one's library."--Foundations of Physics

"A sympathetic but clear-eyed view of his life and work....examined mainly in his own plentiful papers, supplemented by a remarkably wide list of unusual sources....A fine book."--Scientific American

"An outstanding biography of Albert Einstein that one finds oneself reading with sheer pleasure....Pais has produced a lively book that is, at the same time, a major contribution to Einstein scholarship."--Physics Today

Product Description
Having the advantage of knowing Einstein personally during the last nine years of his life and having access to some of his 50,000 pages of letters and science papers, the author fills many gaps about what we know of Einstein's life. It deals with his interest in philosophy, his concern with Jewish destiny, and his opinions of great figures from Newton to Freud. Also depicts the state of physics at the turn of the century and how Einstein transformed the field.

"This lively and entertaining book tells "tales'' of Cardano, Galileo, Huygens, Pascal, Gauss.... The reasoning of the scientists discussed is modernized so as to ease the reader's path; thus this book is not a scholarly discussion of the history of science readable only by experts, but a far more valuable work: a readable introduction to the scientific work discussed and the historical context (both scientific and social) in which it took place. Addressed to a "general audience," it deserves to have a wide one.... The author's own lucid style and accurate presentation translated into a smoothly flowing English make this book one which many, from college student to professional, will no doubt read with pleasure and learning."—Zentralblatt MATH

"The author discusses principal events in the history of science that deserve the attention of devotees of physics and mathematics. The discussion covers a time span of four centuries beginning with the sixteenth century.... The book is a lively account of the lives and achievements of scientists like Cardano, Tartaglia, Galileo, Huygens, Pascal and Gauss.... This book will be enjoyable reading for anyone interested in the history of science."—Mathematical Reviews

"[T]he work is engagingly written and will be enjoyed by those who love mathematics and physics. The rather mathematically sophisticated treatment of some sections will be heavy going for many American readers, but well worthwhile for those whose mastery of geometry and algebra is solid.... The book will be of particular interest to college students majoring in mathematics or physics and to high school students who are enthusiastic about mathematics…. Particularly suitable for the general collections of college libraries and for the libraries of superior high schools."—Choice

"[This is a] readable, informal set of biographical vignettes.... Aimed at the general reader with some background in mathematics, the book's style is to discuss the circumstances that surrounded these great scientists and to give insight into their contributions to science. The discoveries themselves are explained clearly in modern notation, without detailed heuristic discussion, which is appropriate for the casual reader; those needing more historical specificity can look elsewhere. The evolution of research and the dissemination of discoveries are followed and permit interesting comparison.... In sum, this collection is recommended, particularly for its insights."—Edward Paul, Science Books & Films

"Tales of Mathematicians and Physicists is a worthwhile book to read, especially for novices … . But it’s fun for everyone, and enlightening. … it’s especially pleasant to encounter old heroes again and, indeed, learn more about them – much more, in fact: this is serious scholarship and the mathematics is very good. And it would be an easy task to adapt Tales of Mathematicians and Physicists for use as a supplementary text in a course … . It’s a pleasure to recommend this book." (Michael Berg, MathDL, October, 2007)

From the reviews of the second edition:
"The text is based on various articles that appeared in the Soviet journal Quantum (Kvant). The presentation is mostly leisurely, and large parts of the book are accessible to talented high school students … . It is a wonderful book that I recommend to everyone interested in mathematics." (Franz Lemmermeyer, Zentralblatt MATH, Vol. 1105 (7), 2007)


Product Description

This revised and greatly expanded second edition of the Russian text Tales of Mathematicians and Physicists contains a wealth of new information about the lives and accomplishments of more than a dozen scientists throughout five centuries of history: from the first steps in algebra up to new achievements in geometry in connection with physics. The heroes of the book are renowned figures from early eras, such as Cardano, Galileo, Huygens, Leibniz, Pascal, Euler, Lagrange, and Laplace, as well some scientists of last century: Klein, Poincaré, and Ramanujan.

A unique mixture of mathematics, physics, and history, this volume provides biographical glimpses of scientists and their contributions in the context of the social and political background of their times. The author examines many original sources, from the scientists’ research papers to their personal documents and letters to friends and family; furthermore, detailed mathematical arguments and diagrams are supplied to help explain some of the most significant discoveries in calculus, celestial mechanics, number theory, and mathematical physics. What emerges are intriguing, multifaceted studies of a number of remarkable intellectuals and their scientific legacy.

Written by a distinguished mathematician and accessible to readers at all levels, this book is a wonderful resource for both students and teachers and a welcome introduction to the history of science.

Tobias Dantzig , Joseph Mazur and Barry Mazur,
Number : The Language of Science, The Masterpiece Science Edition
Publisher: Pi Press | March 10, 2005 | 416 pages | ISBN: 0131856278 | PDF | 1,38 Mb
Descriptions :
It is the aim of this book to...present the evolution of number as the profoundly human story which it is.
-Tobias Dantzig

This is beyond doubt the most interesting book on the evolution of mathematics which has ever fallen into my hands. If people know how to treasure the truly good, this book will attain a lasting place in the literature of the world. The evolution of mathematical thought from the earliest times to the latest constructions is presented here with admirable consistency and originality and in a wonderfully lively style.
- Albert Einstein

Tobias Dantzig's Number: The Language of Science is one of the truly great classics of mathematical exposition, perhaps the most lucid history of the number concept ever written. Its republication should be a cause for celebration by every scientifically minded person, regardless of his or her mathematical background.
- Eli Maor, author of e: The Story of a Number and To Infinity and Beyond


Tobias Dantzig's Number is a classic. A fascinating account of the evolution of mathematics, it deserves a place on the bookshelf of anyone who is interested in the history of thought.
- Charles Seife, author of Zero and Alpha and Omega

A classic! Anyone interested in the history of numbers and mathematics should read this book.""
- Mario Livio, author of The Golden Ratio

From the rudimentary mathematical abilities of prehistoric man to the counterintuitive and bizarre ideas at the edges of modern math, this masterpiece of science writing tells the story of mathematics through the history of its most central concept: number.

Dantzig succeeds in his aim to reveal a human story, and in making that story accessible to the non-expert. In his friendly and welcoming style, he shows how math developed from basic faculties present in us all, beginning with our ""number sense""¿the ability to discern that an object has been added to or removed from a small collection of objects without counting. The subsequent evolution of the concept of number is inextricably linked with the history of human culture, as Dantzig demonstrates. He shows how advances in math were spurred by the demands of growing commerce in the ancient world; how the pure speculation of philosophers and religious mystics contributed to our understanding of numbers; how the exchange of ideas between cultures in times of war and imperial conquest fueled advances in knowledge; and, ultimately, how the forces of history combine with human intuition to trigger revolutions in thought.

Sweeping in scope, Number is an open doorway into the world of math. Dantzig explains the foundations of mathematics with ease, and eloquently explores deeper philosophical questions that arise along the way. He describes the properties of all kinds of numbers¿integers, primes, irrationals, transcendentals, and more. He explains the significance of zero, and shows that its invention had revolutionary consequences for arithmetic. He shows how the invention of symbols for use in algebra¿a radical departure from tradition at the time¿ushered in a new era of math; how arithmetic and geometry reflect each other; and how calculus uses infinity to model the continuity of space and time.

With a new afterword, notes section, and bibliography written by math professor and author Joseph Mazur, and a new foreword by mathematician Barry Mazur, the Masterpiece Science edition of Number¿which was first published in 1930 is the first update of Dantzig's classic work in over fifty years. It is a story that ranges from the dawn of man to the genius of history's greatest mathematicians, vividly revealing how the pursuit of knowledge transcends the rise and fall of civilizations."
