Markowitz's foundational paper introducing mean-variance portfolio optimisation and the efficient frontier. Reformulates portfolio construction as a quadratic programme in (μ, Σ) and quantifies the variance-reducing role of correlation in diversification.
Einstein's foundational paper generalising the principle of relativity to non-inertial frames and reformulating gravitation as spacetime curvature. Establishes the field equations G_μν = (8πG/c⁴) T_μν and three quantitative predictions confirmed within the decade.
