A simplified account of the history, theory and proofs of Einstein`s revolutionary concept of the universe
From the Preface by the author, J. A. Coleman
"As the title implies, this is a book about relativity, written primarily for those who have had little or no training in mathematics, physics, or astronomy. Technical language is kept to a minimum, and only those mathematical equations which are absolutely necessary for a clear and complete understanding of the theory are included. In short, this book presents the relevant scientific history which proceeded relativity, a complete but simple account of the theory itself, and a detailed description of the various proofs of the theory up to the present.
In this age of modern science the education of the individual, regardless of his field, is not complete without a knowledge of the most fundamental branches of science and their historical background. It is particularly important that those of our younger generation - the scientists of tomorrow - be imbued with an understanding of the laws of nature at an early stage so that their scientific reasoning and general mental ability will mature side by side. The theory of relativity should be a particularly important part of this process.
The theory of relativity has been considered difficult to understand but only because its predictions are difficult to belief - not because of any innate incomprehensibility. To introduce such a challenge to the imagination of the young is to stimulate the mind to great accomplishments in the future, particularly where vision is demanded.
The story behind the theory of relativity is a fascinating one which stirs the imagination more than any fiction created by man possibly could do. For here is a story of theory after theory at first appearing successful but disintegrating upon closer scrutiny ; of repeated attempts at surmounting insurmountable barriers., only to met with continual dismal failure. But at last all barriers are surmounted by a superhuman endeavour which up to now has withstood all tests and attacks. This is the story of relativity.
Looking back on the historical developments of the theory, we are particularly fortunate in being able to see the panorama of a hundred years of history flash before our eyes in but a few hours. But more than that, the theory is unique among scientific endeavours because it touches on many phases of the physical world - from the atomic domain to the make-up of the universe itself.
It is my belief that readers will derive as much enjoyment and inspiration from this book as I did in writing it."
Very good pages with some edge-wear.
