Physicist · 1879 – 1955
Albert Einstein
Key Takeaways
- Einstein's special and general relativity replaced Newton's absolute space and time.
- His equation E=mc² showed mass and energy are equivalent.
- He won the 1921 Nobel Prize for explaining the photoelectric effect, a foundation of quantum theory.
- His 1905 'miracle year' produced four papers that each transformed physics.
Albert Einstein is the most famous scientist of the modern age. In a single year — 1905 — he published papers that overturned classical physics, and a decade later he rewrote the theory of gravity itself.
The miracle year and relativity
In 1905 Einstein introduced special relativity and the equation E=mc². In 1915 his general theory of relativity recast gravity as the curvature of spacetime — a vision confirmed when starlight was seen bending around the Sun in 1919.
Icon and conscience
Building on and surpassing Isaac Newton, Einstein became the 20th century’s symbol of genius. A committed pacifist, he nonetheless urged the development of the atomic bomb against Nazi Germany, a decision that troubled him for the rest of his life.
Influence
Einstein redefined the concepts of space, time, mass and energy, enabling technologies from GPS to nuclear power and making him the 20th century's icon of genius.
Legacy
'Einstein' is a global synonym for genius; his theories remain the foundation of cosmology and modern physics.
Major Works
- On the Electrodynamics of Moving Bodies (1905)
- The Foundation of the General Theory of Relativity (1916)
Controversies
- Signed the 1939 letter urging the US to develop the atomic bomb, which he later regretted.
- Famously resisted quantum indeterminacy: 'God does not play dice.'
Notable Quotes
“Imagination is more important than knowledge.”
“God does not play dice with the universe.”
