Albert Einstein

Albert Einstein was born in Ulm, Germany, and showed early curiosity about nature and abstract reasoning, though his unconventional path through school and the Swiss Polytechnic belied the revolution he would later ignite. After years as a patent clerk in Bern, he published a series of papers in 1905—his annus mirabilis—that transformed understanding of light, matter, and energy.

Special relativity unified space and time and established that the speed of light is constant for all observers, leading to the famous equation E=mc². General relativity, completed in 1915, recast gravity not as a force across empty space but as the curvature of spacetime caused by mass and energy. The theory predicted phenomena such as the bending of starlight and gravitational waves, later confirmed by observation.

Awarded the Nobel Prize in 1921 for explaining the photoelectric effect, Einstein also helped lay foundations for quantum theory while famously debating its interpretation. A pacifist who later warned of nuclear danger, he emigrated to the United States and spent his final decades at the Institute for Advanced Study, pursuing a unified field theory and advocating for civil rights and international cooperation.

1879 — Born in Ulm. Born to a middle-class Jewish family in the German Empire.

1905 — Annus Mirabilis. Published papers on the photoelectric effect, Brownian motion, and special relativity.

1915 — General Relativity. Presented field equations describing gravity as spacetime curvature.

1921 — Nobel Prize. Awarded for services to theoretical physics, especially the photoelectric effect.

1955 — Death in Princeton. Died in New Jersey, leaving a legacy as the twentieth century's emblem of scientific genius.

   Death in Princeton

   Died in New Jersey, leaving a legacy as the twentieth century's emblem of scientific genius.

Einstein did more than advance physics—he changed how humanity imagines the universe. Relativity dismantled absolute space and time, while his quantum contributions opened the atomic age. His celebrity made science a public conversation, and his moral voice on war, racism, and nuclear weapons showed that intellectual achievement carries ethical responsibility. Today his theories are tested daily in particle accelerators, telescopes, and the satellites of global navigation.
