Einstein

Albert Einstein (1879–1955) was a German-born theoretical physicist whose work redefined space, time, mass, and energy. His special theory of relativity (1905) dismantled the Newtonian conception of absolute space and time; his general theory of relativity (1915) reconceived gravity as spacetime curvature. Einstein also made foundational contributions to quantum theory — the photoelectric effect, Bose-Einstein statistics, and the EPR paradox — while famously resisting its Copenhagen interpretation.

The Einstein persona — the solitary patent clerk who overturned physics with thought experiments — has become as consequential as his physics. It established the template for the theoretical physicist as conceptual revolutionary, a role that shaped how subsequent generations understood the relationship between imagination and mathematical rigor.
