 Newtonian mechanics, a description of the particle-like behavior of macroscopic objects, failed to describe very small objects such as electrons.Abductive reasoning was performed to obtain the dynamics of massive objects (particles with mass) such as electrons.The electromagnetic wave equation, the equation that described the dynamics of light, was used as a prototype for discovering the Schrödinger equation, the equation that describes the wave-like and particle-like dynamics of nonrelativistic massive particles.
