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.
Abraham Pais was a physicist, specialising in particle physics, who became a well-known science historian later in life, having worked closely with prominent scientists such as Niels Bohr and Albert Einstein.
This book is a collection of lectures that starts with a biography about Dirac, then it goes for details about the mathematical and physical contribution of the most influential physicist across the history.
Of course going beyond lecture one needs a good background in physics. Spinors interpretation in lecture 4 was the most enjoyable part for me. This mathematical construction that is beautiful and lead dirac to solve one problem that will guide our work after that.
Note the sub-title: this book consists of four lectures about Dirac, his work and developments from it in physics and mathematics, plus Hawking's laughably ignorant memorial address. (He repeatedly insulted his hosts for delaying for 11 years an event that was, in fact, only one year beyond the minimum requirement of ten years post Dirac's death.)
Only the first lecture is really biographical and even that takes time out to discuss Dirac's scientific contributions. From there the book gets progressively more technically challenging, ending with a lecture on the Dirac operator and spinors that in detail is going to be incomprehensible to anyone without an advanced working knowledge of topology. (The gist is that we have no clue what spinors mean, geometrically, in the way we know what vectors and tensors are, for example.)
In between, there's good stuff on antimatter from prediction to present day understanding and similarly Dirac's magnetic monopoles then to now.
Much of this book will go over the heads of the casual reader and if you want anything more than a cursory biography, you will also need to look elsewhere, but for physicists, it's a worthwhile publication.
