Albert Einstein was born in Ulm, Germany, and studied at the Swiss Federal Polytechnic in Zurich. While working as a patent examiner in Bern, he published four papers in 1905 covering the photoelectric effect, Brownian motion, special relativity and the equivalence of mass and energy.

His general theory of relativity, completed in 1915, described gravity as the curvature of space and time. Observations during the solar eclipse of 1919 supported its predictions and brought him international fame. He received the 1921 Nobel Prize in Physics for his work on the photoelectric effect.

Einstein left Germany in 1933, after the Nazi party came to power, and settled in the United States, joining the Institute for Advanced Study in Princeton, New Jersey. In later years he spoke publicly on pacifism, nuclear disarmament and civil rights. He died in Princeton in 1955.

“Science is a wonderful thing if one does not have to earn a living at it. One should earn one’s living by work of which one is sure one is capable. Only when we do not have to be accountable to anyone can we find joy in scientific endeavor.”

Selected works

On a Heuristic Point of View Concerning the Production and Transformation of Light

The proposal that light energy travels in discrete quanta rather than continuous waves, and what that explains about the photoelectric effect.

Scientific paper · 1905
On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat

How the random jittering of tiny particles suspended in a liquid follows from the motion of unseen molecules, and how it can be measured.

Scientific paper · 1905
On the Electrodynamics of Moving Bodies

How measurements of time and distance depend on the observer's motion, and why the speed of light is the same for everyone.

Scientific paper · 1905
Does the Inertia of a Body Depend Upon its Energy Content?

The argument that a body giving off energy loses mass, and that mass and energy are therefore two measures of the same thing.
