A Historical Inquiry into the Relationship Between Theories in Economics and Physics with Emphasis on Adam Smith, Newton, Keynes, and Einstein

Abstract

In light of recent advancements in financial theory, a novel analytical approach—econophysics—has emerged to examine price fluctuations. This interdisciplinary field represents both a contemporary trend within economics and an extension of statistical physics, offering more nuanced analyses of various economic variables. Researchers in econophysics have developed a distinctive framework to model the evolution of financial markets, diverging significantly from traditional financial frameworks. This shift has facilitated the construction of an interdisciplinary paradigm, with theoretical foundations traceable to early parallels identified in the works of pioneering thinkers such as Adam Smith and John Maynard Keynes. Smith's economic theories, for instance, exhibit clear influences from Newton’s three laws of motion, while Keynes's insights display conceptual affinities with Einstein’s theory of relativity. The present study seeks to investigate the origins of both physics and economics in this context, focusing on their conceptual intersections as evidenced in the works of Smith and Newton, Keynes, and Einstein, among others. Finally, the study addresses the emergence of econophysics as a distinct academic discipline, explores its practical applications in financial markets, and outlines the key challenges currently confronting the field.
