Walter Isaacson - Einstein - His Life and Universe

Music continued to be a passion. There were nine violinists in his class, and their teacher noted that they suffered from “some stiffness in bowing technique here and there.” But Einstein was singled out for praise: “One student, by the name of Einstein, even sparkled by rendering an adagio from a Beethoven sonata with deep understanding.” At a concert in the local church, Einstein was chosen to play first violin in a piece by Bach. His “enchanting tone and incomparable rhythm” awed the second violinist, who asked, “Do you count the beats?” Einstein replied, “Heavens no, it’s in my blood.”

His classmate Byland recalled Einstein playing a Mozart sonata with such passion—“What fire there was in his playing!”—that it seemed like hearing the composer for the first time. Listening to him, Byland realized that Einstein’s wisecracking, sarcastic exterior was a shell around a softer inner soul. “He was one of those split personalities who know how to protect, with a prickly exterior, the delicate realm of their intense personal life.” 65

Einstein’s contempt for Germany’s authoritarian schools and militarist atmosphere made him want to renounce his citizenship in that country. This was reinforced by Jost Winteler, who disdained all forms of nationalism and instilled in Einstein the belief that people should consider themselves citizens of the world. So he asked his father to help him drop his German citizenship. The release came through in January 1896, and for the time being he was stateless. 66

He also that year became a person without a religious affiliation. In the application to renounce his German citizenship, his father had written, presumably at Albert’s request, “no religious denomination.” It was a statement Albert would also make when applying for Zurich residency a few years later, and on various occasions over the ensuing two decades.

His rebellion from his childhood fling with ardent Judaism, coupled with his feelings of detachment from Munich’s Jews, had alienated him from his heritage. “The religion of the fathers, as I encountered it in Munich during religious instruction and in the synagogue, repelled rather than attracted me,” he later explained to a Jewish historian. “The Jewish bourgeois circles that I came to know in my younger years, with their affluence and lack of a sense of community, offered me nothing that seemed to be of value.” 67

Later in life, beginning with his exposure to virulent anti-Semitism in the 1920s, Einstein would begin to reconnect with his Jewish identity. “There is nothing in me that can be described as a ‘Jewish faith,’ ” he said, “however I am happy to be a member of the Jewish people.” Later he would make the same point in more colorful ways. “The Jew who abandons his faith,” he once said, “is in a similar position to a snail that abandons his shell. He is still a snail.” 68

His renunciation of Judaism in 1896 should, therefore, be seen not as a clean break but as part of a lifelong evolution of his feelings about his cultural identity. “At that time I would not even have understood what leaving Judaism could possibly mean,” he wrote a friend the year before he died. “But I was fully aware of my Jewish origin, even though the full significance of belonging to Jewry was not realized by me until later.” 69

Einstein ended his year at the Aarau school in a manner that would have seemed impressive for anyone except one of history’s great geniuses, scoring the second highest grades in his class. (Alas, the name of the boy who bested Einstein is lost to history.) On a 1 to 6 scale, with 6 being the highest, he scored a 5 or 6 in all of his science and math courses as well as in history and Italian. His lowest grade was a 3, in French.

That qualified him to take a series of exams, written and oral, that would permit him, if he passed, to enter the Zurich Polytechnic. On his German exam, he did a perfunctory outline of a Goethe play and scored a 5. In math, he made a careless mistake, calling a number “imaginary” when he meant “irrational,” but still got a top grade. In physics, he arrived late and left early, completing the two-hour test in an hour and fifteen minutes; he got the top grade. Altogether, he ended up with a 5.5, the best grade among the nine students taking the exams.

The one section on which he did poorly was French. But his three-paragraph essay was, to those of us today, the most interesting part of all of his exams. The topic was “Mes Projets d’avenir,” my plans for the future. Although the French was not memorable, the personal insights were:

If I am lucky and pass my exams, I will enroll in the Zurich Polytechnic. I will stay there four years to study mathematics and physics. I suppose I will become a teacher in these fields of science, opting for the theoretical part of these sciences.

Here are the reasons that have led me to this plan. They are, most of all, my personal talent for abstract and mathematical thinking ... My desires have also led me to the same decision. That is quite natural; everybody desires to do that for which he has a talent. Besides, I am attracted by the independence offered by the profession of science.

In the summer of 1896, the Einstein brothers’ electrical business again failed, this time because they bungled getting the necessary water rights to build a hydroelectric system in Pavia. The partnership was dissolved in a friendly fashion, and Jakob joined a large firm as an engineer. But Hermann, whose optimism and pride tended to overwhelm any prudence, insisted on opening yet another new dynamo business, this time in Milan. Albert was so dubious of his father’s prospects that he went to his relatives and suggested that they not finance him again, but they did. 71

Hermann hoped that Albert would someday join him in the business, but engineering held little appeal for him. “I was originally supposed to become an engineer,” he later wrote a friend, “but the thought of having to expend my creative energy on things that make practical everyday life even more refined, with a bleak capital gain as the goal, was unbearable to me. Thinking for its own sake, like music!” 72And thus he headed off to the Zurich Polytechnic.

CHAPTER THREE

THE ZURICH POLYTECHNIC

1896–1900

The Impudent Scholar

The Zurich Polytechnic, with 841 students, was mainly a teachers’ and technical college when 17-year-old Albert Einstein enrolled in October 1896. It was less prestigious than the neighboring University of Zurich and the universities in Geneva and Basel, all of which could grant doctoral degrees (a status that the Polytechnic, officially named the Eidgenössische Polytechnische Schule, would attain in 1911 when it became the Eidgenössische Technische Hochschule, or ETH). Nevertheless, the Polytechnic had a solid reputation in engineering and science. The head of the physics department, Heinrich Weber, had recently procured a grand new building, funded by the electronics magnate (and Einstein Brothers competitor) Werner von Siemens. It housed showcase labs famed for their precision measurements.

Einstein was one of eleven freshmen enrolled in the section that provided training “for specialized teachers in mathematics and physics.” He lived in student lodgings on a monthly stipend of 100 Swiss francs from his Koch family relatives. Each month he put aside 20 of those francs toward the fee he would eventually have to pay to become a Swiss citizen. 1

Theoretical physics was just coming into its own as an academic discipline in the 1890s, with professorships in the field sprouting up across Europe. Its pioneer practitioners—such as Max Planck in Berlin, Hendrik Lorentz in Holland, and Ludwig Boltzmann in Vienna—combined physics with math to suggest paths where experimentalists had yet to tread. Because of this, math was supposed to be a major part of Einstein’s required studies at the Polytechnic.
