Einstein: His Life and Universe Page 3

  That approach required him to embrace nonconformity. “Long live impudence!” he exulted to the lover who would later become his wife. “It is my guardian angel in this world.” Many years later, when others thought that his reluctance to embrace quantum mechanics showed that he had lost his edge, he lamented, “To punish me for my contempt for authority, fate made me an authority myself.”7

  His success came from questioning conventional wisdom, challenging authority, 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. Tyranny repulsed him, and he saw tolerance not simply as a sweet virtue but as a necessary condition for a creative society. “It is important to foster individuality,” he said, “for only the individual can produce the new ideas.”8

  This outlook made Einstein a rebel with a reverence for the harmony of nature, one who had just the right blend of imagination and wisdom to transform our understanding of the universe. 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 twentieth century, when Einstein helped usher in the modern age.

  CHAPTER TWO

  CHILDHOOD

  1879–1896

  Maja, age 3, and Albert Einstein, 5

  The Swabian

  He was slow in learning how to talk. “My parents were so worried,” he later recalled, “that they consulted a doctor.” Even after he had begun using words, sometime after the age of 2, he developed a quirk that prompted the family maid to dub him “der Depperte,” the dopey one, and others in his family to label him as “almost backwards.” Whenever he had something to say, he would try it out on himself, whispering it softly until it sounded good enough to pronounce aloud. “Every sentence he uttered,” his worshipful younger sister recalled, “no matter how routine, he repeated to himself softly, moving his lips.” It was all very worrying, she said. “He had such difficulty with language that those around him feared he would never learn.”1

  His slow development was combined with a cheeky rebelliousness toward authority, which led one schoolmaster to send him packing and another to amuse history by declaring that he would never amount to much. These traits made Albert Einstein the patron saint of distracted school kids everywhere.2 But they also helped to make him, or so he later surmised, the most creative scientific genius of modern times.

  His cocky contempt for authority led him to question received wisdom in ways that well-trained acolytes in the academy never contemplated. And as for his slow verbal development, he came to believe that it allowed him to observe with wonder the everyday phenomena that others took for granted. “When I ask myself how it happened that I in particular discovered the relativity theory, it seemed to lie in the following circumstance,” Einstein once explained. “The ordinary adult never bothers his head about the problems of space and time. These are things he has thought of as a child. But I developed so slowly that I began to wonder about space and time only when I was already grown up. Consequently, I probed more deeply into the problem than an ordinary child would have.”3

  Einstein’s developmental problems have probably been exaggerated, perhaps even by himself, for we have some letters from his adoring grandparents saying that he was just as clever and endearing as every grandchild is. But throughout his life, Einstein had a mild form of echolalia, causing him to repeat phrases to himself, two or three times, especially if they amused him. And he generally preferred to think in pictures, most notably in famous thought experiments, such as imagining watching lightning strikes from a moving train or experiencing gravity while inside a falling elevator. “I very rarely think in words at all,” he later told a psychologist. “A thought comes, and I may try to express it in words afterwards.”4

  Einstein was descended, on both parents’ sides, from Jewish trades-men and peddlers who had, for at least two centuries, made modest livings in the rural villages of Swabia in southwestern Germany. With each generation they had become, or at least so they thought, increasingly assimilated into the German culture that they loved. Although Jewish by cultural designation and kindred instinct, they displayed scant interest in the religion or its rituals.

  Einstein regularly dismissed the role that his heritage played in shaping who he became. “Exploration of my ancestors,” he told a friend late in life, “leads nowhere.”5 That’s not fully true. He was blessed by being born into an independent-minded and intelligent family line that valued education, and his life was certainly affected, in ways both beautiful and tragic, by membership in a religious heritage that had a distinctive intellectual tradition and a history of being both outsiders and wanderers. Of course, the fact that he happened to be Jewish in Germany in the early twentieth century made him more of an outsider, and more of a wanderer, than he would have preferred—but that, too, became integral to who he was and the role he would play in world history.

  Einstein’s father, Hermann, was born in 1847 in the Swabian village of Buchau, whose thriving Jewish community was just beginning to enjoy the right to practice any vocation. Hermann showed “a marked inclination for mathematics,”6 and his family was able to send him seventy-five miles north to Stuttgart for high school. But they could not afford to send him to a university, most of which were closed to Jews in any event, so he returned home to Buchau to go into trade.

  A few years later, as part of the general migration of rural German Jews into industrial centers during the late nineteenth century, Hermann and his parents moved thirty-five miles away to the more prosperous town of Ulm, which prophetically boasted as its motto “Ulmenses sunt mathematici,” the people of Ulm are mathematicians.7

  There he became a partner in a cousin’s featherbed company. He was “exceedingly friendly, mild and wise,” his son would recall.8 With a gentleness that blurred into docility, Hermann was to prove inept as a businessman and forever impractical in financial matters. But his docility did make him well suited to be a genial family man and good husband to a strong-willed woman. At age 29, he married Pauline Koch, eleven years his junior.

  Pauline’s father, Julius Koch, had built a considerable fortune as a grain dealer and purveyor to the royal Württemberg court. Pauline inherited his practicality, but she leavened his dour disposition with a teasing wit edged with sarcasm and a laugh that could be both infectious and wounding (traits she would pass on to her son). From all accounts, the match between Hermann and Pauline was a happy one, with her strong personality meshing “in complete harmony” with her husband’s passivity.9

  Their first child was born at 11:30 a.m. on Friday, March 14, 1879, in Ulm, which had recently joined, along with the rest of Swabia, the new German Reich. Initially, Pauline and Hermann had planned to name the boy Abraham, after his paternal grandfather. But they came to feel, he later said, that the name sounded “too Jewish.”10 So they kept the initial A and named him Albert Einstein.

  Munich

  In 1880, just a year after Albert’s birth, Hermann’s featherbed business foundered and he was persuaded to move to Munich by his brother Jakob, who had opened a gas and electrical supply company there. Jakob, the youngest of five siblings, had been able to get a higher education, unlike Hermann, and he had qualified as an engineer. As they competed for contracts to provide generators and electrical lighting to municipalities in southern Germany, Jakob was in charge of the technical side while Hermann provided a modicum of salesmanship skills plus, perhaps more important, loans from his wife’s side of the family.11

  Pauline and Hermann had a second and final child, a daughter, in November 1881, who was named Maria but throughout her life used instead the diminutive Maja. When Albert was shown his new sister for the first time, he was led to believe that she was like a wonderful toy that he would enjoy. His response was to look at her and exclaim, “Yes, but where are the wheels?”12 It may not have been the most perceptive of questions, but it did show that during
his third year his language challenges did not prevent him from making some memorable comments. Despite a few childhood squabbles, Maja was to become her brother’s most intimate soul mate.

  The Einsteins settled into a comfortable home with mature trees and an elegant garden in a Munich suburb for what was to be, at least through most of Albert’s childhood, a respectable bourgeois existence. Munich had been architecturally burnished by mad King Ludwig II (1845–1886) and boasted a profusion of churches, art galleries, and concert halls that favored the works of resident Richard Wagner. In 1882, just after the Einsteins arrived, the city had about 300,000 residents, 85 percent of them Catholics and 2 percent of them Jewish, and it was the host of the first German electricity exhibition, at which electric lights were introduced to the city streets.

  Einstein’s back garden was often bustling with cousins and children. But he shied from their boisterous games and instead “occupied himself with quieter things.” One governess nicknamed him “Father Bore.” He was generally a loner, a tendency he claimed to cherish throughout his life, although his was a special sort of detachment that was interwoven with a relish for camaraderie and intellectual companionship. “From the very beginning he was inclined to separate himself from children his own age and to engage in daydreaming and meditative musing,” according to Philipp Frank, a longtime scientific colleague.13

  He liked to work on puzzles, erect complex structures with his toy building set, play with a steam engine that his uncle gave him, and build houses of cards. According to Maja, Einstein was able to construct card structures as high as fourteen stories. Even discounting the recollections of a star-struck younger sister, there was probably a lot of truth to her claim that “persistence and tenacity were obviously already part of his character.”

  He was also, at least as a young child, prone to temper tantrums. “At such moments his face would turn completely yellow, the tip of his nose snow-white, and he was no longer in control of himself,” Maja remembers. Once, at age 5, he grabbed a chair and threw it at a tutor, who fled and never returned. Maja’s head became the target of various hard objects. “It takes a sound skull,” she later joked, “to be the sister of an intellectual.” Unlike his persistence and tenacity, he eventually outgrew his temper.14

  To use the language of psychologists, the young Einstein’s ability to systemize (identify the laws that govern a system) was far greater than his ability to empathize (sense and care about what other humans are feeling), which have led some to ask if he might have exhibited mild symptoms of some developmental disorder.15 However, it is important to note that, despite his aloof and occasionally rebellious manner, he did have the ability to make close friends and to empathize both with colleagues and humanity in general.

  The great awakenings that happen in childhood are usually lost to memory. But for Einstein, an experience occurred when he was 4 or 5 that would alter his life and be etched forever in his mind—and in the history of science.

  He was sick in bed one day, and his father brought him a compass. He later recalled being so excited as he examined its mysterious powers that he trembled and grew cold. The fact that the magnetic needle behaved as if influenced by some hidden force field, rather than through the more familiar mechanical method involving touch or contact, produced a sense of wonder that motivated him throughout his life. “I can still remember—or at least I believe I can remember—that this experience made a deep and lasting impression on me,” he wrote on one of the many occasions he recounted the incident. “Something deeply hidden had to be behind things.”16

  “It’s an iconic story,” Dennis Overbye noted in Einstein in Love,“the young boy trembling to the invisible order behind chaotic reality.” It has been told in the movie IQ, in which Einstein, played by Walter Matthau, wears the compass around his neck, and it is the focus of a children’s book, Rescuing Albert’s Compass, by Shulamith Oppenheim, whose father-in-law heard the tale from Einstein in 1911.17

  After being mesmerized by the compass needle’s fealty to an unseen field, Einstein would develop a lifelong devotion to field theories as a way to describe nature. Field theories use mathematical quantities, such as numbers or vectors or tensors, to describe how the conditions at any point in space will affect matter or another field. For example, in a gravitational or an electromagnetic field there are forces that could act on a particle at any point, and the equations of a field theory describe how these change as one moves through the region. The first paragraph of his great 1905 paper on special relativity begins with a consideration of the effects of electrical and magnetic fields; his theory of general relativity is based on equations that describe a gravitational field; and at the very end of his life he was doggedly scribbling further field equations in the hope that they would form the basis for a theory of everything. As the science historian Gerald Holton has noted, Einstein regarded “the classical concept of the field the greatest contribution to the scientific spirit.”18

  His mother, an accomplished pianist, also gave him a gift at around the same time, one that likewise would last throughout his life. She arranged for him to take violin lessons. At first he chafed at the mechanical discipline of the instruction. But after being exposed to Mozart’s sonatas, music became both magical and emotional to him. “I believe that love is a better teacher than a sense of duty,” he said, “at least for me.”19

  Soon he was playing Mozart duets, with his mother accompanying him on the piano. “Mozart’s music is so pure and beautiful that I see it as a reflection of the inner beauty of the universe itself,” he later told a friend. “Of course,” he added in a remark that reflected his view of math and physics as well as of Mozart, “like all great beauty, his music was pure simplicity.”20

  Music was no mere diversion. On the contrary, it helped him think. “Whenever he felt that he had come to the end of the road or faced a difficult challenge in his work,” said his son Hans Albert, “he would take refuge in music and that would solve all his difficulties.” The violin thus proved useful during the years he lived alone in Berlin, wrestling with general relativity. “He would often play his violin in his kitchen late at night, improvising melodies while he pondered complicated problems,” a friend recalled. “Then, suddenly, in the middle of playing, he would announce excitedly, ‘I’ve got it!’ As if by inspiration, the answer to the problem would have come to him in the midst of music.”21

  His appreciation for music, and especially for Mozart, may have reflected his feel for the harmony of the universe. As Alexander Moszkowski, who wrote a biography of Einstein in 1920 based on conversations with him, noted, “Music, Nature, and God became intermingled in him in a complex of feeling, a moral unity, the trace of which never vanished.”22

  Throughout his life, Albert Einstein would retain the intuition and the awe of a child. He never lost his sense of wonder at the magic of nature’s phenomena—magnetic fields, gravity, inertia, acceleration, light beams—which grown-ups find so commonplace. He retained the ability to hold two thoughts in his mind simultaneously, to be puzzled when they conflicted, and to marvel when he could smell an underlying unity. “People like you and me never grow old,” he wrote a friend later in life. “We never cease to stand like curious children before the great mystery into which we were born.”23

  School

  In his later years, Einstein would tell an old joke about an agnostic uncle, who was the only member of his family who went to synagogue. When asked why he did so, the uncle would respond, “Ah, but you never know.” Einstein’s parents, on the other hand, were “entirely irreligious” and felt no compulsion to hedge their bets. They did not keep kosher or attend synagogue, and his father referred to Jewish rituals as “ancient superstitions.”24

  Consequently, when Albert turned 6 and had to go to school, his parents did not care that there was no Jewish one near their home. Instead he went to the large Catholic school in their neighborhood, the Petersschule. As the only Jew among the seventy students in his class
, Einstein took the standard course in Catholic religion and ended up enjoying it immensely. Indeed, he did so well in his Catholic studies that he helped his classmates with theirs.25

  One day his teacher brought a large nail to the class.“The nails with which Jesus was nailed to the cross looked like this,” he said.26 Nevertheless, Einstein later said that he felt no discrimination from the teachers. “The teachers were liberal and made no distinction based on denominations,” he wrote. His fellow students, however, were a different matter. “Among the children at the elementary school, anti-Semitism was prevalent,” he recalled.

  Being taunted on his walks to and from school based on “racial characteristics about which the children were strangely aware” helped reinforce the sense of being an outsider, which would stay with him his entire life. “Physical attacks and insults on the way home from school were frequent, but for the most part not too vicious. Nevertheless, they were sufficient to consolidate, even in a child, a lively sense of being an outsider.”27

  When he turned 9, Einstein moved up to a high school near the center of Munich, the Luitpold Gymnasium, which was known as an enlightened institution that emphasized math and science as well as Latin and Greek. In addition, the school supplied a teacher to provide religious instruction for him and other Jews.

  Despite his parents’ secularism, or perhaps because of it, Einstein rather suddenly developed a passionate zeal for Judaism. “He was so fervent in his feelings that, on his own, he observed Jewish religious strictures in every detail,” his sister recalled. He ate no pork, kept kosher dietary laws, and obeyed the strictures of the Sabbath, all rather difficult to do when the rest of his family had a lack of interest bordering on disdain for such displays. He even composed his own hymns for the glorification of God, which he sang to himself as he walked home from school.28
