Flashcards

Photoelectric Effect

Einstein's 1905 theory explaining how light behaves as both a wave and a particle, leading to breakthroughs like solar power.

Brownian Motion

Einstein's 1905 theory explaining the random movement of particles suspended in fluid, providing evidence for atoms.

General Theory of Relativity

Einstein's groundbreaking theory published in 1915, explaining gravity as a curvature of space-time caused by mass and energy.

Special Theory of Relativity

Einstein's influential theory developed in 1905, which states that the laws of physics are the same for all observers in uniform motion, and that the speed light is a constant regardless of the observer's motion.

Global Recognition

  • Awarded the Nobel Prize in Physics for services to theoretical physics (1921)

Leaving Germany

  • Emigrated to the US in 1933 due to Nazi oppression of Jews; had natural talent for mathematics and a love of learning.

Advocating Peace

  • Signed the Russell-Einstein Manifesto in 1955 to warn about nuclear weapons.

Early Life and Career

  • Born in Ulm, Germany to Jewish parents; displayed early mathematical talent; natural scientific talent.
  • Completed schooling in Switzerland.
