Einstein: What is the Theory of Relativity?

by Albert Einstein, Harry Yoon (translator)

What is the Theory of Relativity According to the Man Himself?This short article was originally written by Albert Einstein at the request of The London Times, in 1919, and it was intended for the general audience. If you are interested in getting a general overview, and the historical context, regarding Einstein's relativity, then this is the best introduction for you (~10 pages).Einstein published his two seminal papers on special relativity in 1905, and he published his field equations for gravity (now known as Einstein's field equations) in 1915, which was viewed as the completion of the theory of general relativity.One of the most important predictions of his theory was bending of light in a strong gravitational field. This was confirmed by the English expedition led by Sir Arthur Eddington in 1919, during the solar eclipse, which made Einstein an instant celebrity. This newspaper article was published after Eddington's public announcement of this rather exciting and historical event. (It was right after the end of WWI.)It was originally written by Einstein in German, and both the German and English-translated versions are now in public domain. This short booklet attempts at a new translation to give a somewhat clearer account of what Einstein wanted to convey in his original writing.It is the BEST high-level account of the development of relativity, by Einstein himself!A completely new English translation - 2024!

About the author

Special and general theories of relativity of German-born American theoretical physicist Albert Einstein revolutionized modern thought on the nature of space and time and formed a base for the exploitation of atomic energy; he won a Nobel Prize of 1921 for his explanation of the photoelectric effect.

His paper of 1905 formed the basis of electronics. His first paper, also published in 1905, changed the world.
He completed his Philosophiae Doctor at the University of Zurich before 1909.

Einstein, a pacifist during World War I, stayed a firm proponent of social justice and responsibility.

Einstein thought that Newtonion mechanics no longer enough reconciled the laws of classical mechanics with those of the electromagnetic field. This thought led to the development. He recognized, however, that he ably also extended the principle to gravitational fields and with his subsequent theory of gravitation in 1916 published a paper. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light, which laid the foundation of the photon.

Best known for his mass–energy equivalence formula E = mc2, dubbed "the world's most famous equation," he received "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory.

He visited the United States when Adolf Hitler came to power in 1933 and went not back to Germany. On the eve of World War II, he endorsed a letter, alerting Franklin Delano Roosevelt, president, to the potential development of "extremely powerful bombs of a new type" and recommending that the United States begin similar research. This recommendation eventually led to the Manhattan project. Einstein supported defending the Allied forces but largely denounced the idea of using the newly discovered nuclear fission as a weapon. Later, with Bertrand Russell–Einstein manifesto highlighted the danger of nuclear weapons.

After the rise of the Nazi party, Einstein made Princeton his permanent home as a citizen of United States in 1940. He chaired the emergency committee of atomic scientists, which organized to alert the public to the dangers of warfare.

At a symposium, he advised:

"In their struggle for the ethical good, teachers of religion must have the stature to give up the doctrine of a personal God, that is, give up that source of fear and hope which in the past placed such vast power in the hands of priests. In their labors they will have to avail themselves of those forces which are capable of cultivating the Good, the True, and the Beautiful in humanity itself. This is, to be sure a more difficult but an incomparably more worthy task... "

("Science, Philosophy and Religion, A Symposium," published by the Conference on Science, Philosophy and Religion in their Relation to the Democratic Way of Life, Inc., New York, 1941).

In a letter to philosopher Eric Gutkind, dated 3 January 1954, Einstein stated:

"The word god is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honorable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this."

(The Guardian, "Childish superstition: Einstein's letter makes view of religion relatively clear," by James Randerson, May 13, 2008)

Great intellectual achievements and originality made the word "Einstein" synonymous with genius.

The institute for advanced study in Princeton, New Jersey, affiliated Einstein until his death in 1955.
