The key scientific works of Einstein are concentrated in several revolutionary articles from 1905, as well as in the General Theory of Relativity, completed in 1915–1916. Below are the main works listed by significance and chronology. 1905: The Miracle Year This year Einstein published several articles that radically changed physics. Work Title of the Article Significance On Brownian Motion On the Movement of Particles Suspended in a Stationary Liquid, Required by the Molecular-Kinetic Theory of Heat Evidence of the reality of atoms and molecules, a method for determining their sizes On the Photoelectric Effect On One Heuristic Point of View Concerning the Emission and Transformation of Light Hypothesis of light quanta, the foundation of quantum theory, Nobel Prize in 1921 Special Theory of Relativity On the Electrodynamics of Moving Bodies Abandonment of absolute time and space, the principle of the constancy of the speed of light Equivalence of Mass and Energy Does the inertia of a body depend on the energy contained in it? Equation E = mc², the connection between mass and energy Doctoral Thesis New Definition of Molecular Sizes New method for calculating Avogadro's number and molecular sizes 1915–1916: General Theory of Relativity Work Title of the Article Significance Foundational Work Foundations of the General Theory of Relativity Geometric theory of gravity, curvature of spacetime, explanation of the precession of perihelion of Mercury and the deflection of light Other Important Works ...
