**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*.

But the letter goes on, happily for Mari картинка 27, with a description of what they would do when they met back in Zurich, a passage in which Einstein showed once again why their relationship was so special. “The first thing we’ll do is climb the Ütliberg,” he said, referring to a high point just out of town. There they would be able to “take pleasure in unpacking our memories” of the things they had done together on other hiking trips. “I can already imagine the fun we will have,” he wrote. Finally, with a flourish only they could have fully appreciated, he concluded, “And then we’ll start in on Helmholtz’s electromagnetic theory of light.” 38

In the ensuing months, their letters became even more intimate and passionate. He began calling her Doxerl (Dollie), as well as “my wild little rascal” and “my street urchin”; she called him Johannzel (Johnnie) and “my wicked little sweetheart.” By the start of 1900, they were using the familiar du with one another, a process that began with a little note from her that reads, in full:

My little Johnnie,

Because I like you so much, and because you’re so far away that I can’t give you a little kiss, I’m writing this letter to ask if you like me as much as I do you? Answer me immediately.

A thousand kisses from your Dollie 39

Graduation, August 1900

Academically, things were also going well for Einstein. In his intermediate exams in October 1898, he had finished first in his class, with an average of 5.7 out of a possible 6. Finishing second, with a 5.6, was his friend and math note-taker Marcel Grossmann. 40

To graduate, Einstein had to do a research thesis. He initially proposed to Professor Weber that he do an experiment to measure how fast the earth was moving through the ether, the supposed substance that allowed light waves to propagate through space. The accepted wisdom, which he would famously destroy with his special theory of relativity, was that if the earth were moving through this ether toward or away from the source of a light beam, we’d be able to detect a difference in the observed speed of the light.

During his visit to Aarau at the end of his summer vacation of 1899, he worked on this issue with the rector of his old school there. “I had a good idea for investigating the way in which a body’s relative motion with respect to the ether affects the velocity of the propagation of light,” he wrote Mari картинка 28. His idea involved building an apparatus that would use angled mirrors “so that light from a single source would be reflected in two different directions,” sending one part of the beam in the direction of the earth’s movement and the other part of the beam perpendicular to it. In a lecture on how he discovered relativity, Einstein recalled that his idea was to split a light beam, reflect it in different directions, and see if there was “a difference in energy depending on whether or not the direction was along the earth’s motion through the ether.” This could be done, he posited, by “using two thermoelectric piles to examine the difference of the heat generated in them.” 41

Weber rejected the proposal. What Einstein did not fully realize was that similar experiments had already been done by many others, including the Americans Albert Michelson and Edward Morley, and none had been able to detect any evidence of the perplexing ether—or that the speed of light varied depending on the motion of the observer or the light source. After discussing the topic with Weber, Einstein read a paper delivered the previous year by Wilhelm Wien, which briefly described thirteen experiments that had been conducted to detect the ether, including the Michelson-Morley one.

Einstein sent Professor Wien his own speculative paper on that topic and asked him to write him back. “He’ll write me via the Polytechnic,” Einstein predicted to Mari картинка 29. “If you see a letter there for me, you may go ahead and open it.” There is no evidence that Wien ever wrote back. 42

Einstein’s next research proposal involved exploring the link between the ability of different materials to conduct heat and to conduct electricity, something that was suggested by the electron theory. Weber apparently did not like that idea either, so Einstein was reduced, along with Mari картинка 30, to doing a study purely on heat conduction, which was one of Weber’s specialties.

Einstein later dismissed their graduation research papers as being of “no interest to me.” Weber gave Einstein and Mari картинка 31the two lowest essay grades in the class, a 4.5 and a 4.0, respectively; Grossmann, by comparison, got a 5.5. Adding annoyance to that injury, Weber said that Einstein had not written his on the proper regulation paper, and he forced him to copy the entire essay over again. 43

Despite the low mark on his essay, Einstein was able to eke by with a 4.9 average in his final set of grades, placing him fourth in his class of five. Although history refutes the delicious myth that he flunked math in high school, at least it does offer as a consolation the amusement that he graduated college near the bottom of his class.

At least he graduated. His 4.9 average was just enough to let him get his diploma, which he did officially in July 1900. Mileva Mari картинка 32, however, managed only a 4.0, by far the lowest in the class, and was not allowed to graduate. She determined that she would try again the following year. 44

Not surprisingly, Einstein’s years at the Polytechnic were marked by his pride at casting himself as a nonconformist. “His spirit of independence asserted itself one day in class when the professor mentioned a mild disciplinary measure just taken by the school’s authorities,” a classmate recalled. Einstein protested. The fundamental requirement of education, he felt, was the “need for intellectual freedom.” 45

Throughout his life, Einstein would speak lovingly of the Zurich Polytechnic, but he also would note that he did not like the discipline that was inherent in the system of examinations. “The hitch in this was, of course, that one had to cram all this stuff into one’s mind for the examinations, whether one liked it or not,” he said. “This coercion had such a deterring effect that, after I had passed the final examination, I found the consideration of any scientific problems distasteful to me for an entire year.” 46

In reality, that was neither possible nor true. He was cured within weeks, and he ended up taking with him some science books, including texts by Gustav Kirchhoff and Ludwig Boltzmann, when he joined his mother and sister later that July for their summer holiday in the Swiss Alps. “I’ve been studying a great deal,” he wrote Mari картинка 33, “mainly Kirch-hoff ’s notorious investigations of the motion of the rigid body.” He admitted that his resentment over the exams had already worn off. “My nerves have calmed down enough so that I’m able to work happily again,” he said. “How are yours?” 47
