He spent a little time in Europe, including in Britain in the early s. Finally, he left Europe forever—never to return—in That suited him very well. He lived in Princeton right up to his death in As a Jew, he was very interested in the founding of Israel and took an active role in that. He was a patent clerk in Bern and worked in the patent office for a number of years from Probably his most productive years are those years when he was a patent clerk.

Having said that, he came up with general relativity when he was a professor of physics in Berlin. Also, at the patent office, although he was not known in the academic world, he had some contact with academic physicists like Max Planck who was a key supporter of relativity. But we should remember that he was always involved with those two worlds. Are there any clues as to where his revelations came from?

Did his unconventional background play a part in that? Like many geniuses, he was not particularly successful in his university training. He attended a famous institution—in Zurich—but was always rebelling against his academic education, constantly reading the latest research on his own.

He was not working with other people at all. He was not very successful in his relationships with his university lecturers.

He was a rebel and, because he was so passionate about physics, his best ideas really came from his own reading and thinking. One of the most famous ones concerns chasing a light ray. When he was 16 or 17, he imagined whether you could catch up with a light ray and what that would mean.

Yes, to begin with, it did. He had friends who he tried his ideas out on and often they disagreed—quite violently in some cases—and that improved his thinking. At one point, he did have a collaborator who was a mathematician and they published some work on general relativity together.

Afterwards, he always published alone. The Standard of Greatness by John Rigden from Can you tell us a bit about that? Einstein published five papers that year. All of them are considered of great value. The paper that Einstein regarded as the most revolutionary of his work in was actually about quantum theory. There was another paper about Brownian motion. He showed that the phenomenon of Brownian motion—which had been known for almost years—was actually due to atoms bombarding particles.

This was considered proof of the atomic theory of matter by his fellow physicists — the first time that atoms had really been proved to exist. Then, the last of the five papers concerned probably the most famous equation in science: This came out of his first paper on relativity and was published at the end of This is the principle that energy and mass are two aspects of the same thing.

Yes, and c is the speed of light. Fission was not discovered until later — just before the Second World War, in fact. Can you talk us through that theory? John Rigden puts it quite well in his book. This theory of relativity led to the concept of space-time which is a key thought in general relativity. General relativity was much more comprehensive, it included gravitation and acceleration. General relativity is what we often see illustrated with a rubber sheet with marbles on it distorting the sheet.

Is that right? The experimental proof of general relativity came only later. Probably the most famous aspect of the experimental proof is the bending of a light-ray by the gravitational field of the sun.

The light emitted by distant stars was observed to be bent by the gravitational field of the sun in during an astronomical expedition led by Sir Arthur Eddington, a British astronomer. After that expedition, physicists started to take general relativity much more seriously. There were other experimental proofs as well, but that was the beginning of the idea that general relativity was correct. Before that, it was unproven and Einstein asked astronomers to go looking for it.

ALBERT EINSTEIN - HINDI - FOUNDER OF THEORY OF RELATIVITY

Astronomers were able to back up his theory with observations. So, after we had the proof of general relativity, how was science different? How did the universe look different? What are the implications of that for the way we see the world now?

The whole idea of the Big Bang has been explained, to a great extent, in terms of general relativity. This came much later than Einstein of course — he was dead by then. General relativity also explains the existence of black holes. The whole structure of space and time which Newton imagined, an absolute coordinate system, has been abandoned in favour of a curved space-time formulation.

His achievements in so many papers in such a short period of time seems almost superhuman. But he was just human, right?

Do we risk exaggerating his genius sometimes? He was certainly very human and had many failings as well as an extraordinary scientific imagination. There were a few letters to his wife, and he published a little bit. There is this feeling that it came out of the blue. What we do know is what he published in and that he was fascinated by contradictions in physics.

From that, he concluded that light always moves at a constant speed — independent of the coordinate system you were using to measure it with. Another contradiction that fascinated him was to do with magnetism and electric charge. He imagined that if you had a stationary charge observed by a stationary observer, there would be no magnetic field which could be observed with a compass. So which was true? And he did resolve it, with his theory of relativity. Yes, he did. It was fruitful for his imagination.

He liked contradictions and found them stimulating. With practically no mathematics, he manages to show how various contradictions were perceived by Einstein and then used to create these various papers during that year. Rigden is very good at explaining it in clear language with historical anecdotes nicely integrated into the text. This is a collection of correspondence between Einstein and his friend, the German physicist, Max Born.

What makes the book unique is that the author is German, when most biographers come from the English-speaking world.

To have a German writing on Einstein is particularly interesting. He was born in Germany in and grew up there until he was 16 when he went to join his parents in Italy. He was unhappy with the German educational system: He was not a very willing student in an authoritarian education system. In fact, his whole life was a battle against authority in different forms.

He kept Swiss nationality throughout his life, until he went to the United States and became an American citizen when he was quite old, in So, he is not German by nationality, though he was born there.
