Resumen de ALL or nothing?
Campbell talks about the quest for a unified physics. Unification has been a driving force in physics since at least the days of Newton. Newton's insight unified heavenly and Earthly realms previously considered irreconcilable. His neat set of universally valid equations carved a template for future generations of physicists, while allowing engineers to calculate the forces and torques that made possible the engines of the Industrial Revolution. Wind forward 200 years, and James Clerk Maxwell performed a similarly revolutionary act of unification. In the 1860s, he showed that electricity and magnetism are two facets of the same force, electromagnetism.
