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.

Kurzbeschreibung
Based on the newly released personal letters of Albert Einstein, Walter Isaacson 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.

CHAPTER ONE
THE LIGHT-BEAM RIDER
"I promise you four papers," the young patent examiner wrote his friend. The letter would turn out to bear some of the most significant tidings in the history of science, but its momentous nature was masked by an impish tone that was typical of its author. He had, after all, just addressed his friend as "you frozen whale" and apologized for writing a letter that was "inconsequential babble." Only when he got around to describing the papers, which he had produced during his spare time, did he give some indication that he sensed their significance.
"The first deals with radiation and the energy properties of light and is very revolutionary," he explained. Yes, it was indeed revolutionary. It argued that light could be regarded not just as a wave but also as a stream of tiny particles called quanta. The implications that would eventually arise from this theory -- a cosmos without strict causality or certainty -- would spook him for the rest of his life.
"The second paper is a determination of the true sizes of atoms." Even though the very existence of atoms was still in dispute, this was the most straightforward of the papers, which is why he chose it as the safest bet for his latest attempt at a doctoral thesis. He was in the process of revolutionizing physics, but he had been repeatedly thwarted in his efforts to win an academic job or even get a doctoral degree, which he hoped might get him promoted from a third- to a second-class examiner at the patent office.
The third paper explained the jittery motion of microscopic particles in liquid by using a statistical analysis of random collisions. In the process, it established that atoms and molecules actually exist.
"The fourth paper is only a rough draft at this point, and is an electrodynamics of moving bodies which employs a modification of the theory of space and time." Well, that was certainly more than inconsequential babble. Based purely on thought experiments -- performed in his head rather than in a lab -- he had decided to discard Newton's concepts of absolute space and time. It would become known as the Special Theory of Relativity.
What he did not tell his friend, because it had not yet occurred to him, was that he would produce a fifth paper that year, a short addendum to the fourth, which posited a relationship between energy and mass. Out of it would arise the best-known equation in all of physics: E=mc2.
Looking back at a century that will be remembered for its willingness to break classical bonds, and looking ahead to an era that seeks to nurture the creativity needed for scientific innovation, one person stands out as a paramount icon of our age: the kindly refugee from oppression whose wild halo of hair, twinkling eyes, engaging humanity, and extraordinary brilliance made his face a symbol and his name a synonym for genius. Albert Einstein was a locksmith blessed with imagination and guided by a faith in the harmony of nature's handiwork. His fascinating story, a testament to the connection between creativity and freedom, reflects the triumphs and tumults of the modern era.
Now that his archives have been completely opened, it is possible to explore how the private side of Einstein -- his nonconformist personality, his instincts as a rebel, his curiosity, his passions and detachments -- intertwined with his political side and his scientific side. Knowing about the man helps us understand the wellsprings of his science, and vice versa. Character and imagination and creative genius were all related, as if part of some unified field.
Despite his reputation for being aloof, he was in fact passionate in both his personal and scientific pursuits. At college he fell madly in love with the only woman in his physics class, a dark and intense Serbian named Mileva Maric´. They had an illegitimate daughter, then married and had two sons. She served as a sounding board for his scientific ideas and helped to check the math in his papers, but eventually their relationship disintegrated. Einstein offered her a deal. He would win the Nobel Prize someday, he said; if she gave him a divorce, he would give her the prize money. She thought for a week and accepted. Because his theories were so radical, it was seventeen years after his miraculous outpouring from the patent office before he was awarded the prize and she collected.
Einstein's life and work reflected the disruption of societal certainties and moral absolutes in the modernist atmosphere of the early twentieth century. Imaginative nonconformity was in the air: Picasso, Joyce, Freud, Stravinsky, Schoenberg, and others were breaking conventional bonds. Charging this atmosphere was a conception of the universe in which space and time and the properties of particles seemed based on the vagaries of observations.
Einstein, however, was not truly a relativist, even though that is how he was interpreted by many, including some whose disdain was tinged by anti-Semitism. Beneath all of his theories, including relativity, was a quest for invariants, certainties, and absolutes. There was a harmonious reality underlying the laws of the universe, Einstein felt, and the goal of science was to discover it.
His quest began in 1895, when as a 16-year-old he imagined what it would be like to ride alongside a light beam. A decade later came his miracle year, described in the letter above, which laid the foundations for the two great advances of twentieth-century physics: relativity and quantum theory.
A decade after that, in 1915, he wrested from nature his crowning glory, one of the most beautiful theories in all of science, the general theory of relativity. As with the special theory, his thinking had evolved through thought experiments. Imagine being in an enclosed elevator accelerating up through space, he conjectured in one of them. The effects you'd feel would be indistinguishable from the experience of gravity.
Gravity, he figured, was a warping of space and time, and he came up with the equations that describe how the dynamics of this curvature result from the interplay between matter, motion, and energy. It can be described by using another thought experiment. Picture what it would be like to roll a bowling ball onto the two-dimensional surface of a trampoline. Then roll some billiard balls. They move toward the bowling ball not because it exerts some mysterious attraction but because of the way it curves the trampoline fabric. Now imagine this happening in the four-dimensional fabric of space and time. Okay, it's not easy, but that's why we're no Einstein and he was.
The exact midpoint of his career came a decade after that, in 1925, and it was a turning point. The quantum revolution he had helped to launch was being transformed into a new mechanics that was based on uncertainties and probabilities. He made his last great contributions to quantum mechanics that year but, simultaneously, began to resist it. He would spend the next three decades, ending with some equations scribbled while on his deathbed in 1955, stubbornly criticizing what he regarded as the incompleteness of quantum mechanics while attempting to subsume it into a unified field theory.
Both during his thirty years as a revolutionary and his subsequent thirty years as a resister, Einstein remained consistent in his willingness to be a serenely amused loner who was comfortable not conforming. Independent in his thinking, he was driven by an imagination that broke from the confines of conventional wisdom. He was that odd breed, a reverential rebel, and he was guided by a faith, which he wore lightly and with a twinkle in his eye, in a God who would not play dice by allowing things to happen by chance.
Einstein's nonconformist streak was evident in his personality and politics as well. Although he...
