**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*.

. The description of the equivalence principle follows the formulation that Einstein used in his yearbook article of 1907 and his comprehensive general relativity paper of 1916. Others have subsequently modified it slightly. See also Einstein, “Fundamental Ideas and Methods of Relativity Theory,” 1920, unpublished draft of a paper for

magazine, CPAE 7: 31.

Some of this chapter draws from a dissertation by one of the editors of the

Einstein Papers Project: Jeroen van Dongen, “Einstein’s Unification: General Relativity and the Quest for Mathematical Naturalness,” 2002. He provided a copy to me along with guidance and editing for this chapter. This chapter also follows the research findings of other scholars studying Einstein’s general relativity work. I am grateful to van Dongen and others who met with me and helped me on this chapter, including Tilman Sauer, Jürgen Renn, John D. Norton, and Michel Janssen. This chapter draws on their work and also that of John Stachel, all listed in the bibliography.

In it Einstein writes, “The decisive idea of the analogy between the mathematical formulation of the theory and the Gaussian theory of surfaces came to me only in 1912 after my return to Zurich, without being aware at that time of the work of Riemann, Ricci, and Levi-Civita. This was first brought to my attention by my friend Grossmann.” Einstein 1922c: “I realized that the foundations of geometry have physical significance. My dear friend the mathematician Grossmann was there when I returned from Prague to Zurich. From him I learned for the first time about Ricci and later about Riemann.”

. An explanation of this dilemma is in Renn and Sauer 1997, 42–43. The

mystery of why Einstein in early 1913 could not find the correct gravitational tensor—and the issue of his understanding of coordinate condition options—is addressed nicely in Renn 2005b, 11–14. He builds on, and suggests some revisions to, the conclusions of Norton 1984.

21

. Norton, Janssen, and Sauer have all suggested that Einstein’s bad experience in 1913 of abandoning a mathematical strategy for a physical one, and his subsequent belated success with a mathematical strategy, is reflected in the views he expressed in his 1933 Spencer lecture at Oxford and also his approach in the later decades of his life to finding a unified field theory.
