Product Description
All atomic particles have a particular "spin," analogous to the earth's rotation on its axis. The quantum mechanical reality underlying spin is complex and still poorly understood. Sin-itiro Tomonaga's The Story of Spin remains the most complete and accessible treatment of spin, and is now available in English translation. Tomonaga tells the tale of the pioneers of physics and their difficult journey toward an understanding of the nature of spin and its relationship to statistics. His clear unfolding of the tale of spin is invaluable to students of physics, chemistry, and astronomy, and his description of the historical development of spin will interest historians and philosophers of science."This piece of the history of physics will provide excellent and exciting reading. . . . It also provides the personal touch of an expert in the field that is so often lacking in the physics literature. I recommend it very highly."—Fritz Rohrlich, Physics TodaySin-itiro Tomonaga was awarded the Nobel Prize for Physics in 1965.

A story about the hardships involved in the beginning of the 1900s with the birth of Quantum Mechanics. As a physicist one only hears about the great physicists in text books with theory's, experiments, and equations named after them. One even wonders if these scientists were humans or superhumans because colleagues speak of them so 'godly'. Tomonaga brings these great physicists 'down' to earth and describes the atmosphere at the time of incredible struggle. He brings to the forefront the pains the scientists went through, the frictions between mentor and apprentice, the battle to look for a pattern in the data, and the incredible enlightenment accompanied by the resolution of a problem. This story is not simply of spin. It is also about LIFE, finding meaning in the struggle. Tomonaga spells out for you the hardships involved for every scientist working on problems; thinking outside the box, the everlasting obstacle. But it is in this where nature speaks truth as Tomonaga describes. For scientists and laypeople alike, this story is about people trying to figure out nature, quantum nature. The scientists are not superhumans, filled with the spirits or god(s). Real people who really struggled, who cried and cursed to find a solution. A great book about the great human stuggle written by one who solved a great problem.

This is a series of twelve lectures of the physics of the spin angular momentum, and essentially quantum mechanical notion allied only metaphorically to the macroscopic world. Not, perhaps, in all its implications-the theory of ferromagnetism gets short shrift- but in its essential physical aspects. The topics include spectroscopy, Thomas precession (which one of my undergraduate professors could never fully believe), relativistic quantum mechanics, and statistical physics. It's all very rewarding. Expounding on "the wide range of physics with varying degrees of difficulty" that understanding spin requires, the translator's preface quotes the Feynman Lectures, "It appears to be one of the few places in physics where there is a rule which can be stated very simply, but for which no one has found a simple and easy explanation. The explanation is deep down in relativistic quantum mechanics. This probably means that we do not have a complete understanding of the fundamental principle involved." The translator, Takeshi Oka, is a professor at the Enrico Fermi Institute at the University of Chicago, and the introduction is from 1996. We can trust his assessment of the situation and conjecture that it probably hasn't changed much since then. The approach is collegial rather than academic and to anyone with a modest physics or mathematics background (e.g., someone with physics minor or an elementary understanding of vectors and differential equations), the treatments should be sufficiently accessible to use as an introduction. For an educated reader with no mathematical background, I think only lectures 9 and 11 will be a total wash, although another six will be rough going (but. I'd hope, rewarding). Although the lectures aren't overly mathematical, at least in the sense that a physicist would use the term, the lectures contain mathematics. Some equations are shown, others swiftly derived and one or two proofs are introduced. Many times, Tomonaga introduces ideas to explain why a particular aspect of the mathematics, i.e., spinors, was needed or created. The intuitive descriptions of the mathematics and intimate explanations of how ideas were derived are invaluable for understanding the nature of spin.

Mr. Tomonaga deserves that expression more than others because of his sensitivity and sweetness (if such things can be said about physicists ;) .. the book speaks for itself and is a 'must read' for anyone interested in physics or the history of physics :) enuf said ;)

Nice

Although you can find the same story in other sources, this one is definitely a time-saving reading. The informal style is a plus for those who are not familiar with quantum theory.

This is one of my favourite physics books. I have always had difficulties understanding the nature of spin and this book explains it with unsurpassable style. There are so many aspects to spin that it requires the brilliant exposition of someone like Tomonaga to unpack all its subtleties: spin is not simply the self-rotation of the electron, it is also a subtle property of isotropic space. As well, spin is at the heart of particle statistics in quantum field theory. In nuclear physics, the concept of spin was also coopted into a description of iso-tropic space! Not only does Tomonaga describe the theoretical aspects of spin, but he patiently recounts the breakthough (now obscure) experiments that measured it. Some of the highlights of the book include an discussion of the nature of vectors and tensors and an immensely readable history of second quantisation that leads to quantum field theory. It is interesting to contrast Tomanaga's style with the other 2 physicists who shared the Nobel prize in electrodynamics with him. From the folksy iconoclasm of Richard Feynman to the brutal formalistic abstraction of Julian Schwinger (who broke the back of Physical Review with his third paper on electrodynamics which is one of the most equation heavy paper ever written). Then there is Tomonaga, who epitomises simplicity and clarity, with a clear-eyed reverence for the rich history of physics. He is above all, a sympathetic teacher - he tells you when something is difficult - for instance, explaining how Dirac stumbled on second quantisation "Why must you quantize it once more as the name second quantization suggests? We mortals stand bewildered here. Howerver, there is no use being bewildered, so let us try to discover why we feel bewildered." It's no wonder that Freeman Dyson said that it was only with the framework of Tomonaga, could he weave Feynman and Schwinger together into a comprehensible whole.However, this book is not just a text-book on spin, in its pages, there is a superb history of quantum mechanics. Tomonaga gives a blow-by-blow account of the development of quantum mechanics, quantum field theory and nuclear physics, as it relates to spin. Through the recreation of the arguments and counter-arguments of the old masters of quantum mechanics, he has brought to life these characters that so dominated physics in the golden era of the 20's and 30's.
