# Albert Einstein

Albert Einstein transformed humanity's understanding of space, time, and energy with his special (1905) and general (1915) theories of relativity, earning the 1921 Nobel Prize in Physics for his discovery of the photoelectric effect. His famous mass-energy equivalence, E=mc², underpins both nuclear physics and modern cosmology. Einstein's public advocacy for pacifism, civil rights, and international cooperation made him one of the most recognized and admired figures of the 20th century.
