Albert Einstein is one of the most influential and recognized scientists in history. He is best known for his theories of special and general relativity and his postulation of mass–energy equivalence as expressed by the famous equation E = mc2. In 1905, often called his miracle year, Einstein published five papers, one of which (on his quantum theory of light) won him a Nobel Prize in 1921. Einstein has become the iconic scientific genius of the 20th century, and his picture continues to be featured seemingly everywhere, even a half century after his death.

After measurements taken during a total solar eclipse in 1919 proved Einstein's theory of general relativity was correct, his popularity soared, and he instantly became an international celebrity. Time magazine named Einstein Person of the Century in its final issue of 1999. Einstein's theories radically changed the way we view the universe, laid the groundwork for modern physics, and led to some of the most significant scientific and technological advances in human history.

The Early Years

Albert Einstein was born into a Jewish family in Ulm, Germany, on March 14, 1879. Einstein's interest in science was first sparked at the age of 5 when his father showed him a compass and explained that magnetism caused the needle to always point north. He was fascinated by the fact that there are forces in nature that cannot be seen, and the experience left a lasting impression on him.

In 1885, Einstein began his education at the age of 6 at a neighborhood Catholic primary school in Munich, Germany. He moved on to secondary school in 1888 and became interested in physics, math, and philosophy the following year. By the time he was 11, Einstein could prove the Pythagorean theorem by himself, and by age 12, he had taught himself calculus.

In 1894, Einstein's family moved to Italy but left him behind in Munich to finish his schooling. Einstein was unhappy, however, and left school after his teacher told him he would not amount to anything because of his irreverence. The following year, Einstein tried to enroll in the Swiss Federal Polytechnical Institute 2 years early, but he failed the nonscience parts of the entrance exam. In 1896, he retook the exam and began school that fall. Four years later, Einstein graduated, and in 1902, he began working as a clerk in the Swiss Patent Office in Bern, Switzerland.

Year of Miracles

In 1905, at the age of 25, Einstein had a sudden burst of progress and published five scientific papers, including three of his most important, in his spare time while working at the patent office. In that 1 year, Einstein proposed his revolutionary quantum theory of light, helped prove the existence of atoms, was able to explain Brownian motion, radically changed the way we think of space and time, and came up with science's most famous equation: E = mc2.

Einstein submitted his first paper of the year—the one that would earn him a Nobel Prize in 1921—to Annalen der Physik (Annuals of Physics) in March, and it was published 3 months later. In the paper, “On a Heuristic Point of View Concerning the Production and Transformation of Light,” Einstein put forth his revolutionary particle theory of light. For two centuries, scientists had thought of light as a continuous wave. Einstein, however, postulated that light is actually made up of many point-like particles—light quanta—later termed photons. By thinking of light as particles, Einstein laid the foundation for quantum theory and was able to explain the photoelectric effect—something that had puzzled scientists for almost 20 years.
