In the history of physics, the concept of fields had its origins in the 18th century in a mathematical formulation of Newton's law of universal gravitation, but it was seen as deficient as it implied action at a distance. In 1852, Michael Faraday treated the magnetic field as a physical object, reasoning about lines of force.

A golden age of physics began with the simultaneous discovery of the principle of the conservation of energy in the mid-19th century. [7] [8] A golden age of physics was the years 1925 to 1927. [9] The golden age of nonlinear physics was the period from 1950 to 1970, encompassing the Fermi–Pasta–Ulam–Tsingou problem and others. [10]
