**By the author of the acclaimed bestseller *Benjamin Franklin*, this is the first full biography of Albert Einstein since all of his papers have become available.**
How did his mind work? What made him a genius? Isaacson's biography shows how his scientific imagination sprang from the rebellious nature of his personality. His fascinating story is a testament to the connection between creativity and freedom.
Based on newly released personal letters of Einstein, this book explores how an imaginative, impertinent patent clerk -- a struggling father in a difficult marriage who couldn't get a teaching job or a doctorate -- became the mind reader of the creator of the cosmos, the locksmith of the mysteries of the atom and the universe. His success came from questioning conventional wisdom and marveling at mysteries that struck others as mundane. This led him to embrace a morality and politics based on respect for free minds, free spirits, and free individuals.
These traits are just as vital for this new century of globalization, in which our success will depend on our creativity, as they were for the beginning of the last century, when Einstein helped usher in the modern age.
### Amazon.com Review
As a scientist, Albert Einstein is undoubtedly the most epic among 20th-century thinkers. Albert Einstein as a man, however, has been a much harder portrait to paint, and what we know of him as a husband, father, and friend is fragmentary at best. With *Einstein: His Life and Universe*, Walter Isaacson (author of the bestselling biographies *Benjamin Franklin* and *Kissinger*) brings Einstein's experience of life, love, and intellectual discovery into brilliant focus. The book is the first biography to tackle Einstein's enormous volume of personal correspondence that heretofore had been sealed from the public, and it's hard to imagine another book that could do such a richly textured and complicated life as Einstein's the same thoughtful justice. Isaacson is a master of the form and this latest opus is at once arresting and wonderfully revelatory. *--Anne Bartholomew*

**Five Questions for Walter Isaacson**
**Amazon.com:** What kind of scientific education did you have to give yourself to be able to understand and explain Einstein's ideas?
**Isaacson:** I've always loved science, and I had a group of great physicists--such as Brian Greene, Lawrence Krauss, and Murray Gell-Mann--who tutored me, helped me learn the physics, and checked various versions of my book. I also learned the tensor calculus underlying general relativity, but tried to avoid spending too much time on it in the book. I wanted to capture the imaginative beauty of Einstein's scientific leaps, but I hope folks who want to delve more deeply into the science will read Einstein books by such scientists as Abraham Pais, Jeremy Bernstein, Brian Greene, and others.
**Amazon.com:** That Einstein was a clerk in the Swiss Patent Office when he revolutionized our understanding of the physical world has often been treated as ironic or even absurd. But you argue that in many ways his time there fostered his discoveries. Could you explain?
**Isaacson:** I think he was lucky to be at the patent office rather than serving as an acolyte in the academy trying to please senior professors and teach the conventional wisdom. As a patent examiner, he got to visualize the physical realities underlying scientific concepts. He had a boss who told him to question every premise and assumption. And as Peter Galison shows in *Einstein's Clocks, Poincare's Maps*, many of the patent applications involved synchronizing clocks using signals that traveled at the speed of light. So with his office-mate Michele Besso as a sounding board, he was primed to make the leap to special relativity.
**Amazon.com:** That time in the patent office makes him sound far more like a practical scientist and tinkerer than the usual image of the wild-haired professor, and more like your previous biographical subject, the multitalented but eminently earthly Benjamin Franklin. Did you see connections between them?
**Isaacson:** I like writing about creativity, and that's what Franklin and Einstein shared. They also had great curiosity and imagination. But Franklin was a more practical man who was not very theoretical, and Einstein was the opposite in that regard.
**Amazon.com:** Of the many legends that have accumulated around Einstein, what did you find to be least true? Most true?
**Isaacson:** The least true legend is that he failed math as a schoolboy. He was actually great in math, because he could visualize equations. He knew they were nature's brushstrokes for painting her wonders. For example, he could look at Maxwell's equations and marvel at what it would be like to ride alongside a light wave, and he could look at Max Planck's equations about radiation and realize that Planck's constant meant that light was a particle as well as a wave. The most true legend is how rebellious and defiant of authority he was. You see it in his politics, his personal life, and his science.
**Amazon.com:** At *Time* and CNN and the Aspen Institute, you've worked with many of the leading thinkers and leaders of the day. Now that you've had the chance to get to know Einstein so well, did he remind you of anyone from our day who shares at least some of his remarkable qualities?
**Isaacson:** There are many creative scientists, most notably Stephen Hawking, who wrote the essay on Einstein as "Person of the Century" when I was editor of *Time*. In the world of technology, Steve Jobs has the same creative imagination and ability to think differently that distinguished Einstein, and Bill Gates has the same intellectual intensity. I wish I knew politicians who had the creativity and human instincts of Einstein, or for that matter the wise feel for our common values of Benjamin Franklin.

### **From Publishers Weekly**
**Acclaimed biographer Isaacson examines the remarkable life of "science's preeminent poster boy" in this lucid account (after 2003's *Benjamin Franklin* and 1992's *Kissinger*). Contrary to popular myth, the German-Jewish schoolboy Albert Einstein not only excelled in math, he mastered calculus before he was 15. Young Albert's dislike for rote learning, however, led him to compare his teachers to "drill sergeants." That antipathy was symptomatic of Einstein's love of individual and intellectual freedom, beliefs the author revisits as he relates his subject's life and work in the context of world and political events that shaped both, from WWI and II and their aftermath through the Cold War. Isaacson presents Einstein's research—his efforts to understand space and time, resulting in four extraordinary papers in 1905 that introduced the world to special relativity, and his later work on unified field theory—without equations and for the general reader. Isaacson focuses more on Einstein the man: charismatic and passionate, often careless about personal affairs; outspoken and unapologetic about his belief that no one should have to give up personal freedoms to support a state. Fifty years after his death, Isaacson reminds us why Einstein (1879–1955) remains one of the most celebrated figures of the 20th century. *500,000 firsr printing, 20-city author tour, first serial to *Time*; confirmed appearance on *Good Morning America*.

. Another formulation of the experiment would be for one observer to measure the position of a particle while at the “same moment” another observer measures the momentum of its twin. Then they compare notes and, supposedly, know the position and momentum of both particles. See Charles Seife, “The True and the Absurd,” in Brockman, 71.

Note that Arthur Fine says that the synopsis of EPR used by Bohr “is closer to a caricature of the EPR paper than it is to a serious reconstruction.” Fine says that Bohr and other interpreters of Einstein feature a “criterion of reality” that Einstein in his own later writings on EPR does not feature, even though the EPR paper as written by Podolsky does talk about determining “an element of reality.” Brian Greene’s book is among those that do emphasize the “criterion of reality” element.

. Arthur Fine has shown that Einstein’s own critique of quantum mechanics

was not fully captured in the way that Podolsky wrote in the EPR paper, and especially in the way that Bohr and the “victors” described it. Don Howard has built on Fine’s work and emphasized the issues of “separability” and “locality.” See Howard 1990b.

. In the decoherent-histories formulation of quantum mechanics, the coarse graining is such that the histories don’t interfere with one another: if A and B are mutually exclusive histories, then the probability of A or B is the sum of the probabilities of A and of B as it should be. These “decoherent” histories form a tree-like structure, with each of the alternatives at one time branching out into alternatives at the next time, and so forth. In this theory, there is much less emphasis

on measurement than in the Copenhagen version. Consider a piece of mica in which there are radioactive impurities emitting alpha particles. Each emitted alpha particle leaves a track in the mica. The track is real, and it makes little difference whether a physicist or other human being or a chinchilla or a cockroach comes along to look at it. What is important is that the track is correlated with the direction of emission of the alpha particle and

could be used

to measure the emission. Before the emission takes place, all directions are equally probable and contribute to a branching of histories. I am grateful to Murray Gell-Mann for his help with this section. See also Gell-Mann, 135–177; Murray Gell-Mann and James Hartle, “Quantum Mechanics in the Light of Quantum Cosmology,” in W. H. Zurek, ed.,
