Biography

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist whose groundbreaking work in modern physics changed how we understand space, time, energy, and gravity. Born in Ulm, Württemberg, then part of the German Empire, Einstein moved to Switzerland in 1895 and later gave up his German citizenship. He studied at ETH Zurich, graduating in 1900 with a teaching diploma in mathematics and physics. After working at the Swiss Patent Office in Bern, he earned his PhD at the University of Zurich in 1905.

In 1905, often called Einstein's 'miracle year,' he published four major papers that changed physics. These papers introduced special relativity, explained the photoelectric effect, offered proof for atoms through Brownian motion, and set out the mass-energy equivalence formula E=mc². His work on the photoelectric effect earned him the Nobel Prize in Physics in 1921, although he is best known for the theory of relativity.

By 1915, Einstein had completed his theory of general relativity, which described gravity as a curvature of spacetime caused by mass and energy, rather than a force. This theory made several predictions that were later observed, such as light bending around massive objects and the way Mercury's orbit shifts. The theory dramatically changed our view of the universe and laid the foundations for modern cosmology.

Einstein's personal life included two marriages: first to Mileva Marić in 1903, with whom he had three children, and later to his cousin Elsa Einstein in 1919. His career took him from the Swiss Patent Office to top academic roles, including at the Prussian Academy of Sciences in Berlin in 1914. When the Nazis came to power in 1933, Einstein, who was Jewish, moved to the United States, joining the Institute for Advanced Study at Princeton. He spent his last years trying to develop a unified field theory and passed away in Princeton on 18 April 1955.

Before Fame

Einstein's rise to scientific fame began during a time of rapid progress in physics at the early 20th century. Growing up in a middle-class Jewish family, he showed an early talent for math and physics, even though he struggled with traditional schooling. When his family moved to Italy when he was fifteen, he left behind Germany's strict school system and continued his studies in the freer environment of Switzerland.

The late 19th and early 20th centuries brought major discoveries in physics that questioned classical Newtonian mechanics. Scientists were dealing with issues like electromagnetic radiation, light behavior, and atomic structure. Einstein's job at the Swiss Patent Office, where he assessed electromagnetic devices, gave him practical knowledge about the physical principles he would later change through his theoretical work.

Key Achievements

  • Developed the theory of special relativity (1905) and general relativity (1915)
  • Explained the photoelectric effect, earning the 1921 Nobel Prize in Physics
  • Formulated the mass-energy equivalence principle expressed as E=mc²
  • Provided mathematical proof of atomic theory through explanation of Brownian motion
  • Made significant contributions to quantum theory and statistical mechanics

Did You Know?

  • 01.Einstein's brain was removed without family permission after his death and studied for decades by researchers seeking to understand the source of his genius
  • 02.He played the violin throughout his life and once said that if he had not been a physicist, he would probably have been a musician
  • 03.Einstein refused surgery for an abdominal aneurysm in 1955, stating 'I want to go when I want. It is tasteless to prolong life artificially'
  • 04.He was offered the position of President of Israel in 1952 following the death of the country's first president, but declined the honor
  • 05.Einstein's famous tongue-out photograph was taken on his 72nd birthday when he grew tired of posing for photographers
