Subtle Is the Lord: The Science and the Life of Albert Einstein

Rate this book
Since the death of Albert Einstein in 1955 there have been many books and articles written about the man and a number of attempts to "explain" relativity. In this new major work Abraham Pais, himself an eminent physicist who worked alongside Einstein in the post-war years, traces the development of Einstein's entire oeuvre. This is the first book which deal comprehensively and in depth with Einstein's science, both the successes and the failures.

Running through the book is a completely non-scientific biography (identified in the table of contents by italic type) including many letters which appear in English for the first time, as well as other information not published before.

Throughout the preparation of this book, Pais has had complete access to the Einstein Archives (now in the possession of the Hebrew University) and the invaluable guidance of the late Helen Dukas--formerly Einstein's private secretary.

Spinoza’s Man

Although he had a lifelong interest in philosophy, Einstein had a limited background in the subject, mainly Kant and Plato. He had even less knowledge of theology. Yet I am impressed by his intuitive understanding of the subject and its relevance to his scientific work. Quips about God and dice aside, his scientific ethos can be associated with a theology as nuanced as the quote used as the title of Païs biography: “Subtle is the Lord; but malicious He is not.”

Einstein made only a few explicit comments about religion. Perhaps his most informative was the statement: “A religious person is devout in the sense that he has no doubt of the significance of those superpersonal objects and goals which neither require nor are capable of rational foundation.” The phrase ‘superpersonal objects’ is important - not supernatural, or spiritual, or divine, one notices. And Païs reports him as saying in his later years: “Science without epistemology is—in so far as it is thinkable at all—primitive and muddled.” The phrase has explicit philosophical import - how we may connect words to things that are not words underlies all 0f human inquiry.

In line with Kantian epistemology, these objects, these things, that Einstein refers to are literally everything there is in the universe. They are unknowable for what they are in themselves. They first must be perceived by limited human sense capabilities, even capabilities enhanced by technology. Even more fundamentally, they must be expressed in language. And words are not non-words. Words have no logical foundation except in other words. And even language itself is superpersonal, that is beyond the capacity of individual human beings to comprehend entirely much less control.

So Einstein’s epistemological stance in the first instance implies an inherent uncertainty about the world, and with that a requirement for scientific humility. But humility does not imply incapacity. It is here that Einstein seems to make his theological presumption: the universe wants, or at least allows, itself to be known. It supplies what human beings need to be able to investigate it. This is one interpretation of what Enlightenment philosophers have called the Principle of Sufficient Reason.

Theologians call this principle ‘Revelation’ and study it in a sub-discipline called Fundamental Theology. This refers to essentially the same thing as the Principle of Sufficient Reason, namely the ability of human beings to receive comprehensible messages about something that is unknowable in its infinity. Typical dogmatic theology - Christian or any other sort - understands that human knowledge of the divine must be incomplete but then insists on limiting what can be known to some rather arbitrary text or interpretation, thus effectively deifying language as well as causing untold misery by attempting to enforce interpretive restrictions.

Einstein’s God is not the dogmatic God of Christianity or Orthodox Judaism. As Païs says, “If he had a God it was the God of Spinoza.” He bases this on Einstein’s admiring statement about the man: “Although he lived three hundred years before our time, the spiritual situation with which Spinoza had to cope peculiarly resembles our own. The reason for this is that he was utterly convinced of the causal dependence of all phenomena, at a time when the success accompanying the efforts to achieve a knowledge of the causal relationship of natural phenomena was still quite modest.”

I think it is interesting that for Spinoza there are two categories of things which exist, substances and modes. Substances, it seems to me, are what Kant would later call things-in-themselves; and modes are the equivalent of descriptions, that is to say, adjectival expressions, thus language. Substances generate modes, but Spinoza is not terribly specific about how this is accomplished. Modes also refer to ways in which God can be described. The modes of God are essentially everything, all the individual substances, of the universe. Thus there is but one substance, and that substance communicates continuously through people, events, molecules, galaxies, etc.

Like Spinoza, Einstein believed that ‘the universe would provide.’ Some have liked to call that belief ‘faith.’ I think that would be a terrible misconstrual. An abiding hope perhaps but not faith in the Christian sense, simply because it was a belief with no fixed content. In fact quite the opposite. Einstein as a scientist was never dogmatic about, for example, the meaning of quantum physics, although he disagreed with the interpretations of many of his colleagues. And this applied not just to scientific results but also to scientific methods for obtaining results:
“He [the scientist] must appear to the systematic epistemologist as a type of unscrupulous opportunist: he appears as realist in so far as he seeks to describe a world independent of the acts of perception; an idealist in so far as he looks upon the concepts and theories as the free inventions of the human spirit (not logically derivable from what is empirically given); as positivist in so far as he considers his concepts and theories justified only to the extent to which they furnish a logical representation of relations among sensory experiences. He may even appear as a Platonist or Pythagorean in so far as he considers the viewpoint of logical simplicity as an indispensable and effective tool of his research”


In short, Einstein was a pragmatist not a dogmatist. His view that “Science without religion is lame, religion without science is blind.”is therefore not some sentimental blanket approval of theology. It is a very specific, although sparsely worked out, statement of the kind of religion that was compatible with his conception of science. Spinoza never started a church or a cult. The idea is absurd. So is the idea that Einstein had some sort of dogmatic faith, that he was even in some way an ‘anonymous Christian’ as the Jesuit Karl Rainer would have it. No, in addition to being a genius, he was also theologically thoughtful. He was Spinoza’s man.

In this extremely impressive book, Abraham Pais, himself a good physicist who knew Einstein personally, sets out to write a comprehensive biography of the greatest scientist of modern times. The emphasis is very much on the science, and if you want details on who Einstein slept with you are advised to look elsewhere. I think that's absolutely right; most biographies of Lindsay Lohan are, for similar reasons, equally sketchy concerning her opinions on quantum mechanics.

Really illuminating and surprisingly critical on two fronts. One, Pais is critical of Einstein himself and does not write the usual hagiography of the great man, but deals with him as a working scientist who made occasional errors as all humans do. The relativity "revolution" is put in perspective as a continuation of classical physics, by comparison with the true break with the past that was occurring in quantum theory. He is also aware that Einstein's opposition to quantum theory cannot be dismissed with the usual tagline of "God does not play dice." The opposition to QM is deeper and more philosophical in nature and concerns the criteria needed for any theory to be considered an account of objective reality, a question scientists have not even begun to consider and one which Bell's theorem does not clear up at all (Bell spoke on the same issue at the end of his life in speaking about the be-ables of a theory, which do not include the wave function). Einstein knew how isolated he was in later years from the mainstream of physics but then again he was always an outsider from day one. It would be difficult if not impossible for a person like this to succeed in physics (or anywhere in academia) today, as we are much more social and prone to groupthink in our current approach to knowledge.

Originally published on my blog here in June 1998.

Subtle is the Lord... (the Einstein quote finishes "...but he is not malicious") is an excellent biography of Albert Einstein written by an eminent physicist. A fair knowledge of physics is necessary to read this, but reading a biography of Einstein which doesn't convey the work that he did is much less interesting to those who have such a knowledge.

Pais is not uncritical of Einstein. A major theme of his book is to answer the question of why, after the major achievements of special and general relativity and his quantum mechanics papers, Einstein produced so little work of permanent value in the second half of his working life. In fact, Pais suggests that the very aspects of Einstein's character which made the earlier breakthroughs possible meant that his work became more divorced from the mainstream of twentieth century theoretical physics as time went on.

Subtle is the Lord is rather less interested in the non-physics related activities of Albert Einstein, though considerable space is given to his pacifism and Zionism. There are other biographies which concentrate on these matters, and are much more interested in Einstein's private life. Pais' work is where to come for a definitive description of the way in which Einstein's work and life fitted together.

Non-physicists need not apply.

This book is an intensely thorough scientific biography of Einstein and is likely a great joy to any physicist interested watching the great man work.

However, if you're simply a pop-sci fan passing through the fascinating world of physics, don't stop to gawk here. You won't comprehend a thing. Instead, mosy on over to Walter Isaacson's 'Einstein: His Life and Dreams.'

I may return to this book later, once I've got some relativity and quantum theory under my belt, in order to get a better idea of how Einstein actually did his physics.

In my scant readings of the comprehensible parts of this book, however, I did manage to learn a few interesting things about Einstein's successes and failures that any aspiring scientist might take note of. (Note: I'm purely analyzing his characteristics in their role as his effectiveness as a scientist, not as a human being. "Faults" of Einstein the scientist may very well be great virtues of Einstein the man.)

Successes:

Determination
When Einstein encountered a problem, he didn't drop it until he solved it. Special and general relativity took about a decade each, and he spent at least another three decades searching for a unified field theory. The only thing that stopped him from finding that UFT was death. Though he had a great curiosity that led him all throughout the field of physics, around the world, and in and out of international politics and music, he also had the focus to continually return to the same problems from slightly different angles and levels of maturity.

Openness to Discussion
Though Einstein disliked teaching regular courses (it forced him to divert interest away from whatever physical problem was currently vexing him), he loved discussing current problems in physics with professors and students of all levels, even undergraduates. He frequented many philosophical and literary circles as a young man as well. Although his greatest papers were independent works, I suspect his willingness to converse with others (regardless of prestige) expanded his mind greatly and likely gave him clues that assisted him on his quest for cosmic discovery.

Failures:

Maintenance of Health
Though famous for his vegetarian diet, Einstein loathed sports and avoided physical exercise. Illness plagued much of his life and I can't help but think how much more he would have discovered had he maintained his health and wits about him. (Note: I know what you're thinking. Maybe all that sick time was the very reason he was so effective since it would have given him a bit of isolation and rest with which to think deeply about physics. Not so however. Einstein's most creative period (during which he completed his work on special and general relativity and his Nobel work on particle physics) occurred as a young man, before his health declined considerably. His later years are markedly less productive.)

Distraction
Though as a younger man, Einstein eschewed teaching duties and did his best to free himself of distractions from his physics, in hist later years (beginning in the 1920s), he devoted a great deal of time to politics (particularly pacifism and Zionism), fundraising, and administrative work (pertaining to various universities and societies) and generally relinquished his style of intellectual focus and isolation. For such a change, Einstein the scientist surely suffered at the expense of Einstein the human being.

*I did not rate this book since I didn't have the qualifications to read even close to a majority of it.

This is probably the BEST of all the Einstein biographies on the market. It is not only a bio of Einstein himself, but also of his science. With a combination of life story and physics Pais weaves a detailed tapestry of the history of the birth of modern Physics. This book is not for the faint of heart, it takes dedication and patience to work through. The result, wether you understand all the math or not, is a deeper understanding of Einstein's dedication to the pursuit of the greatest of miracles - the human mind's ability to make sense out of nature.

Hmmm... well I think this book should have been called:
" The SCIENCE SCIENCE SCIENCE of Albert Einstein (with a tiny bit of context about his life)"

This is a book by a physicist, for physicists. (I am in no way a physicist.) To his credit, the author makes clear in the introduction that the purpose of the book is to cover Einstein's work, and he even highlights in the contents the (very few) sections in the book which deal with Einstein's life rather than work.

Despite knowing that, I made an attempt to read through the book hoping to stretch my brain on the topic of physics. Pretty much every page has at least a couple of formulas, which I skipped straight over, and much of the content is discussing either the details of the most recent formula or how it was arrived at and inspired by others. For a layperson, these parts are sometimes very interesting and sometimes unintelligible. The start and end of the chapters usually provided some (scientific) background on the papers and periods of Einstein's career, and these served to form an interesting history of physics over the late 19th and early 20th centuries.

I did learn a lot of things. I learnt about the old, mistaken concept of an aether. I read the material about special relativity slow enough to grasp most of it and to be able to explain it to others in laymen's terms. As for general relativity, I understood very little except that Einstein managed to solve the age old riddle of what caused gravity and predicted a few other related phenomena, such as the bending of light around the sun, which were later confirmed to great fanfare. I saw how Einstein worked mostly alone, especially in his early years, having very little knowledge of what else was going on in the world of physics, even re-discovering some phenomena by his own derivation because he wasn't widely read. I was looking forward to reading about his involvement in the development of the atom bomb, but came to learn that all he did was write a letter urging the US to get to work on it. I saw how theoretical physics is so, so, so coupled with complex mathematics; Einstein in fact teamed up with gifted mathematicians in order to solve some of his biggest challenges. Most surprisingly for me, I learnt that, aside from relativity, Einstein made massive contributions to quantum physics, and that he spent a large part of his career on that issue and on trying to unify it with relativity. And finally, I learnt that, without his make-up on, Charlie Chaplin looks like this.

I struggled my way through to the half way point trying to read every page, but had grown very tired by that point, so I made a resolution to only read pages with no formulae on them and I sped through the rest quite quickly without feeling like I was missing much.

tl;dr - If you're a physicist, you'll probably love this book. If you're not, you probably won't, but you might learn some interesting stuff by reading it.

“The aspiration of truth is more precious than its assured possession”. Those were Albert Einstein’s words from his autobiographical note written about a month prior he took his last breath. The spirit with which he wrote bears the seed of the pursuit of an unified field theory from which all the attributes of the Nature will pop out. This is an active field of research in theoretical physics of our present time to search for a theory that unifies the quantum and the classical domains. Such were many of Einstein’s work which he did and it opened doors to uncharted territories of the laws of Nature which got unraveled during his time. It has been over a century that the theories given by him on quantum mechanics and relativity holds remarkable consistency with experiments. The latest of which is the detection of gravitational waves by LIGO experiments(USA) on September 2015 upon merger of two black holes 1.3 billion years ago from now, affecting detectors in a way persistent with the prediction obtained from Einstein's theoretical work. Mathematician & physicist Henri Poincaré was the first person to mention about the existence of gravitational waves and with stupendous effort in formulating General Theory of Relativity from which the equations of gravitational waves was found by Einstein. Although we realize the need of revising his extremely elegant theories owing to the concepts of high gravitational field regime like singularities in black holes, his zeal for the unified theory still stays put.

In his book, author Abraham Pais sketches a biography of Albert Einstein which ponders in Einstein’s work in much of technical depth and also paints an excellent picture of the progress of late 19th to mid 20th century physics. This beautifully written book will help readers to appreciate the Genius of Einstein and how his ideas and work perpetuated during his lifetime. The author does justice in focusing on contribution of many other scientists those who had very crucial contribution in raising apt and subtle questions that led to revolutionary ideas in physics.
I will highly wish the readership of the book to be extended more and more for everyone to have an understanding of how the modern science had humble beginnings in very subtle questions and ideas. It is very important to know through Einstein’s life as an example how a human being is potent of imagining great heights and human abilities of extreme determination to remain fixated on fundamental queries that can unleash the answers to how all of Nature works. One would not fail to notice the ideas Einstein never renounced even though the success was no where close and the majority, including finest of physicists, walked on different paths. Einstein’s dedication, tenacity and strength remind me of the song written by Bengali poet & First Indian Nobel Laureate Rabindranath Tagore: "Jodi tor daak shune keu na ashe, tobey ekla cholo re". (Should no one come to your call, then walk alone). Walked alone he did for the last three decades of his life in the pursuit of unified field theory, a theory which paved the foundation for modern theories aiming to unite all the forces of Nature. Such a theory he foresaw, should be of simplistic structure being pregnant with all the attributes of our reality that we perceive. Einstein’s life runs parallel with a majestic revolution in laws of physics of which he was one of the pioneers and learning about the ways he adopted and the intellect he possessed is one of the bliss of knowledge in itself.

There's a saying from "A Brief History of Time" by Steven Hawking to the effect that "For every equation in the book the readership would be halved...". Clearly that doesn't hold in the limit, because by rough estimate this book has 300 or so equations, implying that even if the original readership with no equations were the entire earth's population of seven billion, as published it would be 7 X 10^9 X 2^(-300). So I could not have read the book, but I did.
I have advanced degrees in mathematics and engineering and have studied my share of physics (30 or so years ago). But this was still a hard read for me. Although I did make my way through some fraction of the equations I can't claim to have fully understood 1/2 of them. Nevertheless it was a fascinating read, made all the more so by the equations. I'm glad that Pias did not shy away from outlining the technical details of the half starts and final conclusions of the subjects of Einsteins study.
I gave it a score of 4 because 3 is too low, but I really thought it was a 3.5. I did not care for some aspeccts of Pais' writing style, and I would have prefered a "popular" introduction to or summary of each concept. But all in all I enjoyed the book because it gave me an insight into the physics of the first half of last century and the nature of the genius behind the name "Albert Einstein".

Terrifically clear exposition of Einstein's development as a thinker....Not for those intimidated by equations; but from Brownian motion to Einstein-Bose condensate, one comes away with how his supple mind fit things together. Far more respectful of science - and the scientifically interested reader - than any of the other more superficial biographies of Einstein I've read...

Subtle is the Lord is a biography of Albert Einstein by Abraham Pais. It brilliantly tells the story of Einstein and his development into a world-renowned Physicist. While covering his life, the book also covers the work that Einstein did in Physics. Starting with his youth and childhood, Subtle is the Lord addresses the theories of Einstein being bad in school by presenting his report card. Although it is true that Einstein didn’t particularly like the authoritative atmosphere of his school, he did not get terrible marks. He taught himself Differential and Integral Calculus by the time he was 16 or so and was wonderful at math.

While Einstein might have had some professional stumbling blocks, most people can agree that 1905 was the year for Einstein. He published six papers that year, with one of them gaining him the Nobel Prize and the others firmly planting him in the upper echelons of physicists. The six papers are:
(1. The light-quantum and the Photoelectric Effect. This one led to the Nobel Prize and was completed on March 17.
(2. A new determination of molecular dimensions, completed April 30. This one became his doctoral thesis and was quoted quite often.
(3. Brownian Motion, received May 11. A direct outgrowth of his thesis work.
(4. The first paper on Special Relativity, received June 30.
(5. The second paper on Special Relativity, containing E = mc^2 received September 27.
(6. The second paper on Brownian Motion, received December 19.

I particularly like the book because it doesn’t shy away from the Mathematics of Einstein’s theories. It discusses the ideas behind the things he developed and shows the state of affairs for each thing beforehand. For instance, before 1905 Einstein published some papers that he felt were lacking once he discovered the works of Gibbs and Boltzmann. It talks about his work on Brownian Motion, his work on the Photoelectric Effect, Special and General Relativity and many of the other things that he had a hand in. With Pais being a Physicist himself, he is able to explain the equations and what they mean.

This particular copy of Subtle is the Lord was printed in 1982, so it does not have further developments on Einstein’s theories and how they are accepted or denied now.

This has been on my bookshelf for many years and has been read and reread several times.

OK, you probably need to be a physicist or a mathematician to really understand the technical detail, because this is quite definitely a history of the intellectual development of Einstein rather than a personal biography. For those able to cope with that it is by far the best history of Relativity and Einstein's love-hate relationship with quantum mechanics that is available.

This isn’t a typical biography. Anyone looking for a digestible book about Einstein’s life and work should look elsewhere, such as to Isaacson’s biography.

I found the book to be oddly compelling, despite many shortcomings.

It tries in many ways to follow narrative threads, but then it still jumps around a lot in ways that are jarring. For example, the chapter on Einstein’s later work on unified field theories begins with Einstein’s death in 1955, then backs up to Einstein’s views in 1917, then covers general advances in the 1910s and 1920s, then describes Einstein’s first paper on a unified field theory in 1922, then backs up to provide background on work by others in the 1910s, then moves forward with Einstein’s work in the 1930s. And so on.

Books can jump around in time effectively if they are adept at holding the reader’s hand. Good detective novels do this, when a detective solves a murder by piecing together what happened from various fragments supplied from various interviews and pieces of evidence. (I especially like the Bernie Gunther novels by Philip Kerr.) But Pais isn’t a great writer in that regard. He tries to hold the reader’s hand, but does it in a very awkward way, saying, “I just described X, next I’ll describe Y, and then in part 3 of the book I’ll say more about Z.

Another shortcoming is that Pais’s book seeks to explain Einstein’s work, but often does so through a lot of equations that are poorly explained. Unless you already know a lot about the topic it would be difficult to follow—and if you already know a lot about the topic, you probably don’t need the explanations. (For background, I got my bachelor’s in physics about 25 years ago, but my memory of the details is dim.)

I did like that the book showed Pais’s affection toward Einstein. (In Einstein’s later years, the two of them often walked and talked at the Institute for Advanced Study.) I like that, nonetheless, Pais was critical of Einstein’s approaches in certain areas (quantum mechanics, unified field theory), and that he pointed out Einstein’s imperfections. For one, he wasn’t a mathematical genius, and often made mistakes in his math. Also, Einstein would generate a lot of ideas, and become enamored of the latest version, describing it is “definitive,” only to then change his mind weeks or months later.

Nonetheless, Pais argued that Einstein was a true genius, a term he wanted to use carefully. And even aside from genius, Pais appreciated Einstein’s approach to work. Pais writes that “the most striking characteristics of [Einstein’s] way of working” were his “devotion to the voyage, enthusiasm, and an ability to drop without pain, regrets, or afterthought, one strategy and to start almost without pause on another one” (pages 341-342).

There is one target audience and one target audience only that this book is meant for and that is serious physicists who are at home with GR/QM mathematics who would like an up close and personal account of the history behind Einstein's breakthroughs. There is no effort to make the book accessible in any way to amateur physics enthusiasts. I still took away a few things from the book. For instance, I had always imagined that Einstein spent an intense couple of years to formulate GR which was then born as a full fledged theory in one fell swoop - while this image is true for special relativity, I was surprised to learn that Einstein had many false starts before finally fleshing out GR. Other learnings were on just how revolutionary his photoelectric effect paper was, how he was pretty much the sole champion of the physical reality of the light quanta for many years and about how there are quantum mechanical effects exhibited in room temperature (specific heat of diamonds) that he was the first to explain. Despite all this, look elsewhere unless Lorentz groups and Bianchi identities are second nature to you!!!

I bought this book because I wanted to better understand how Einstein developed his theory of general relativity. It exceeded my expectations. I’ve read a lot of popular science books that explain relativity at a high level and talk about Einstein’s contributions, but this book goes way deeper and covers a lot more ground. It is quite scholarly in style and has lots of equations (there will be some sections you might want to skip over). It doesn’t cover as much as Einsteins personal life as other books, but if you want to understand the science and why Einstein truly was a genius, this is THE book to get. I only take off a star because in some sections it is almost too thorough and highly technical, which makes it harder work to persist. But if you do persist, it is worth it.

Un libro complesso, che combina una ricerca storica e bibliografica sulla vita e sulla produzione scientifica di Einstein con un livello di dettaglio che assume una conoscenza della fisica a livello post-universitario. Come ogni libro di fisica che si rispetti, rimuovendo gli "ovviamente", i "chiaramente", i "ne segue immediatamente" si riduce ogni capitolo di circa 10 pagine. Pur potendo apprezzare solo parzialmente i contenuti tecnici, la mole di informazioni e la capacità di collocarle nel periodo storico valgono la lettura. Bellissime le appendici, che spaziano dalla storia delle proposte per assegnare il premio Nobel ad Einstein ad una biografia di tutti i suoi collaboratori.

This book describes in detail the scientific accomplishments of Albert Einstein, the most important scientific figure of the twentieth century. Prof. Pais describes in detail how concepts were when Prof. Einstein started working on those problems, how he changed those concepts, and what new problems or areas of research were generated from them.

I am going to list some points which struck me when I read this book. Hopefully, one will not interpret them as giving out spoilers as this is not a work of fiction and there is no dramatic ending. They are:

1. Einstein essentially rediscovered the basic principles of statistical mechanics in his papers from 1902-1904 without knowing that similar investigations had been done by James Clerk Maxwell, Ludwig Boltzmann, and Willard Gibbs.
2. Einstein believed in an ether at least as late as 1902. He showed in his special relativity paper of 1905 that ether is unnecessary in descriptions of physical phenomena.
3. A paper by Einstein in 1904, though not containing any novel results, contained an expression which later led him to partical-wave duality for radiation in 1909, momentum properties of photon in 1916, and partical-wave duality for matter in 1924 before the discovery of wave mechanics! If he had extended his results of 1924-25, he would have become a co-discoverer of wave mechanics. The first paper by Erwin Schrödinger was published in January 1926. I should mention that Einstein did knew of de Broglie's work on matter waves by the time he did this last work.
4. Only 3 pages of Einstein's light-quantum paper of 1905 dealt with photoelectric effect. Rest of the paper dealt with statistical and thermodynamic considerations. This paper had 16 pages in total.
5. If Einstein hadn't introduced his "cosmological" term in his gravitational field equations to model the universe, he would have become a theoretical discoverer of the fact that universe is expanding.

A very in depth look at the history of Einstein's life work, with enough biography to provide context. This book is replete with the math and details of the theories of Einstein and his contemporaries. The problem is that unless you majored in physics or even studied at the graduate level, you aren't going to comprehend the details. Terms like Brownian motion, blackbody radiation, and covariance are not defined in the text. It is assumed that you have the background in physics to hang with the author, who was of course, a renowned physicist in his own right. I toughed it out for about 1/3 of the book, constantly checking Wikipedia before I gave up. I turned to "Einstein's Cosmos" by Kaku, which is perfect for the layperson.

An excellent book, a one of a kind biography of Einstein. Pais was a physicist himself who personally knew both Einstein and Bohr, and made this unique biography of the science of Einstein. If you want to know more about the personal life of Einstein, look elsewhere for Pais only gives a faint sketch of it. On the other hand he delves into the science, the philosophy and the thinking of the man. Pais doesn't shy away from equations and leads he reader with the actual math Einstein and others were doing, and the book is so much richer for it. I dare say that Einstein would preferred this biography of his over all others!

PS: If you plan to read this, have a pencil and notebook on the side to work through the math. It is more fun that way
