This theory revolutionized our understanding of space and time by proposing that the laws of physics are the same for all observers in uniform motion.

In the same year as his special theory of relativity, Einstein published another groundbreaking paper on the photoelectric effect.

This phenomenon occurs when light, typically in the form of photons, strikes a material surface and liberates electrons from it. Also Read: Timeline of Albert Einstein. Einstein explained the photoelectric effect by proposing that light energy is quantized into discrete packets of energy, now known as photons. He suggested that the energy of these photons is directly related to their frequency, and this insight provided crucial support for the emerging field of quantum mechanics.

For his work on the photoelectric effect, Einstein was awarded the Nobel Prize in Physics in Building on his special theory of relativity, Einstein developed the general theory of relativity, which is a theory of gravitation. General relativity made a groundbreaking prediction: the bending of light by gravitational fields. General relativity has become a fundamental theory in modern physics and has implications for our understanding of the universe on both cosmic and quantum scales.

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. 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 Warin 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. 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 do they talk about in the letters? It was a long friendship.
