Paul Dirac: The Man and his Work

Paul Adrien Maurice Dirac was one of the founders of quantum theory. He is numbered alongside Newton, Maxwell and Einstein as one of the greatest physicists of all time. Together the lectures in this volume, originally presented on the occasion of the dedication ceremony for a plaque honoring Dirac in Westminster Abbey, give a unique insight into the relationship between Dirac's character and his scientific achievements. The text begins with the dedication address given by Stephen Hawking at the ceremony. Then Abraham Pais describes Dirac as a person and his approach to his work. Maurice Jacob explains how Dirac was led to introduce the concept of antimatter, and its central role in modern particle physics and cosmology. This is followed by David Olive's account of the origin and enduring influence of Dirac's work on magnetic monopoles. Finally, Sir Michael Atiyah explains the deep and widespread significance of the Dirac equation in mathematics.

I have ofter wondered about Dirac who I consider the mystery man of quantum physics. He seemed to be totally consumed my the underlying mathematics of physics, at the same time he was so naive about the trifles of human interchanges. This is a concise and illuminating history and I assume, the one that another recent book about Dirac is based. The book clears the clouds.

A man Stephen Hawking calls 'probably the greatest British theoretical physicist since Newton,' has got to be a pretty bright man. Paul Dirac wrote the definitive equasion that joined the Theory of Relativity and Quantum Mechanics. Like Einstein before him, his equasion is very simple to express, very complex in its overall impact. It explains things like how television sets or computers work.
This book is not exactly a biography, but more a tribute to him. It is a series of four talks given about Dirac eleven years after his death, upon the dedication of a plack to him in Westminster Abby.
Abraham Pais describes Dirac's character and his approach to his work.
Maurice Jacob explains not only how and why Dirac was led to introduce the concept of antimatter, but also its central role in modern particle physics and cosmology.
David Olive gives an account of Dirac's work on magnetic monopoles and shows how it has had a profound influence in the development of fundamental physics down to the present day.
Sir Michael Atiyah explains the widespread significance of the Dirac equation in mathematics, its roots in algebra and its implications for geometry and topology.

We were ourselves participating in the inauguration of the Paul Dirac memorial in Westminster Abbey. Especially the speeches of Stephan Hawking and Abraham Pais were very touching as they did not only touch Dirac's work but also his personality and life. He was a very complex person and a great physicist. This book reflects that more than others about him.

After missing the first collection of essays on this brilliant recluse published soon after his death, I picked up the present version as soon as I was able. It did not disappoint.
The book is a collection of four lectures given in the subject's honor in 1995 on the tenth anniversary of his death. The final lecture and the latter part of the third are highly mathematical and technical and clearly intended for a professional audience.
But for me, the first lecture by Abraham Pais is worth the purchase price alone. Pais was not only a contemporary physicist, but also a close friend and as close to a confidant as was possible with such a reticent man.
Through Pais' eyes, we see a mathematician turned physicist who was very different from the man to whom Dirac is most frequently compared, Albert Einstein. Einstein was a physicist first, mathematician second. Dirac was exactly the opposite. Einstein became a social and political critic, Dirac never strayed far from his study. The two were similar in that both viewed mathematical beauty as primary and both hated the modern remake of quantum mechanics (after the initial theory) for very similar reasons. This last point was interesting as Dirac was the first one to combine all his contemporaries' work on this improved quantum physics into a formal mathematical structure. His resulting equation, called naturally the Dirac equation, is classic Dirac, short and sweet. It combined Einsteinian relativity with the new quantum theory and Dirac considered the result to govern most of physics and all of chemistry. Stephen Hawking, the renowned theoretical physicist, says in his introductory memorial address to the book, "If Dirac had patented the equation ... he would have become one of the richest men in the world. Every television set or computer would have paid him royalties." For this work, Dirac shared the 1933 Nobel Prize with German physicist Erwin Schroedinger. One unexpected consequence of this work was a mathematical conclusion that defined a "negative energy" matter (aka antimatter) solution. Simply put, he had discovered a universe noone had imagined. To this day, we see the effects of this discovery from medical necessities (PET scan imaging-Positron Emission Tomography) to science fiction (Star Trek).
The quotations and anecdotes Pais chooses are well placed and often very funny. They are also supported by the images of Dirac portrayed in the sketch on the cover and in the few photographs scattered through the first two lectures. They reveal his character well. He saw mathematical and physical realities so clearly that he simply could not understand why others did not see them as well. The photo of him "listening" to future Nobel Laureate Richard Feynman in Maurice Jacob's section is one of the most amusing of the collection.
In the second lecture, Jacob shows the path of discovery and effect on latter day experimental physics of antimatter. He goes too long in spots but is generally fine.
