Einstein (19 page)

Then he published his critique of Boltzmann’s theories. He noted that they worked well in explaining heat transfer in gases but had not yet been properly generalized for other realms. “Great as the achievements of the kinetic theory of heat have been in the domain of gas theory,” he wrote, “the science of mechanics has not yet been able to produce an adequate foundation for the general theory of heat.” His aim was “to close this gap.”

This was all quite presumptuous for an undistinguished Polytechnic student who had not been able to get either a doctorate or a job. Einstein himself later admitted that these papers added little to the body of physics wisdom. But they do indicate what was at the heart of his 1901 challenges to Drude and Boltzmann. Their theories, he felt, did not live up to the maxim he had proclaimed to Grossmann earlier that year about how glorious it was to discover an underlying unity in a set of phenomena that seem completely separate.

In the meantime, in November 1901, Einstein had submitted an attempt at a doctoral dissertation to Professor Alfred Kleiner at the University of Zurich. The dissertation has not survived, but Mari
told a friend that “it deals with research into the molecular forces in gases using various known phenomena.” Einstein was confident. “He won’t dare reject my dissertation,” he said of Kleiner, “otherwise the shortsighted man is of little use to me.”

By December Kleiner had not even responded, and Einstein started worrying that perhaps the professor’s “fragile dignity” might make him uncomfortable accepting a dissertation that denigrated the work of such masters as Drude and Boltzmann. “If he dares to reject my dissertation, then I’ll publish his rejection along with my paper and make a fool of him,” Einstein said. “But if he accepts it, then we’ll see what good old Herr Drude has to say.”

Eager for a resolution, he decided to go see Kleiner personally. Rather surprisingly, the meeting went well. Kleiner admitted he had not yet read the dissertation, and Einstein told him to take his time. They then proceeded to discuss various ideas that Einstein was developing, some of which would eventually bear fruit in his relativity theory. Kleiner promised Einstein that he could count on him for a recommendation the next time a teaching job came up. “He’s not quite as stupid as I’d thought,” was Einstein’s verdict.“Moreover, he’s a good fellow.”

Kleiner may have been a good fellow, but he did not like Einstein’s dissertation when he finally got around to reading it. In particular, he was unhappy about Einstein’s attack on the scientific establishment. So he rejected it; more precisely, he told Einstein to withdraw it voluntarily, which permitted him to get back his 230 franc fee. According
to a book written by Einstein’s stepson-in-law, Kleiner’s action was “out of consideration to his colleague Ludwig Boltzmann, whose train of reasoning Einstein had sharply criticized.” Einstein, lacking such sensitivity, was persuaded by a friend to send the attack directly to Boltzmann.

Marcel Grossmann had mentioned to Einstein that there was likely to be a job at the patent office for him, but it had not yet materialized. So five months later, he gently reminded Grossmann that he still needed help. Noticing in the newspaper that Grossmann had won a job teaching at a Swiss high school, Einstein expressed his “great joy” and then plaintively added, “I, too, applied for that position, but I did it only so that I wouldn’t have to tell myself that I was too faint-hearted to apply.”

In the fall of 1901, Einstein took an even humbler job as a tutor at a little private academy in Schaffhausen, a village on the Rhine twenty miles north of Zurich. The work consisted solely of tutoring a rich English schoolboy who was there. To be taught by Einstein would someday seem a bargain at any price. But at the time, the proprietor of the school, Jacob Nüesch, was getting the bargain. He was charging the child’s family 4,000 francs a year, while paying Einstein only 150 francs a month, plus providing room and board.

Einstein continued to promise Mari
that she would “get a good husband as soon as this becomes feasible,” but he was now despairing about the patent job. “The position in Bern has not yet been advertised so that I am really giving up hope for it.”

Mari
was eager to be with him, but her pregnancy made it impossible for them to be together in public. So she spent most of November at a small hotel in a neighboring village. Their relationship was becoming strained. Despite her pleas, Einstein came only infrequently to visit her, often claiming that he did not have the spare money. “You’ll surely surprise me, right?” she begged after getting yet another note canceling a visit. Her pleadings and anger alternated, often in the same letter:

If you only knew how terribly homesick I am, you would surely come. Are you really out of money? That’s nice! The man earns 150 francs, has room and board provided, and at the end of the month doesn’t have a cent to his name! ... Don’t use that as an excuse for Sunday, please. If you don’t get any money by then, I will send you some . . . If you only knew how much I want to see you again! I think about you all day long, and even more at night.

Einstein’s impatience with authority soon pitted him against the proprietor of the academy. He tried to cajole his tutee to move to Bern with him and pay him directly, but the boy’s mother balked. Then Einstein asked Nüesch to give him his meal money in cash so that he would not have to eat with his family. “You know what our conditions are,” Nüesch replied. “There is no reason to deviate from them.”

A surly Einstein threatened to find new arrangements, and Nüesch backed down in a rage. In a line that could be considered yet another maxim for his life, Einstein recounted the scene to Mari
and exulted, “Long live impudence! It is my guardian angel in this world.”

That night, as he sat down for his last meal at the Nüesch household, he found a letter for him next to his soup plate. It was from his real-life guardian angel, Marcel Grossmann. The position at the patent office, Grossmann wrote, was about to be advertised, and Einstein was sure to get it. Their lives were soon to be “brilliantly changed for the better,” an excited Einstein wrote Mari
. “I’m dizzy with joy when I think about it,” he said. “I’m even happier for you than for myself. Together we’d surely be the happiest people on the earth.”

That still left the issue of what to do about their baby, who was due to be born in less than two months, by early February 1902. “The only problem that would remain to be solved would be how to keep our Lieserl with us,” Einstein (who had begun referring to their unborn child as a girl) wrote to Mari
, who had returned home to have the baby at her parents’ house in Novi Sad. “I wouldn’t want to have to give her up.” It was a noble intention on his part, yet he knew that it would be difficult for him to show up for work in Bern with an illegitimate child. “Ask your Papa; he’s an experienced man, and knows the world better than your overworked, impractical Johnnie.” For good measure,
he declared that the baby, when born, “shouldn’t be stuffed with cow milk, because it might make her stupid.” Mari
’s milk would be more nourishing, he said.
