James Clerk Maxwell

Disciplines:

physics/theoretical physics
physics/electromagnetism
physics/thermodynamics

Summary

Scottish physicist who formulated the Maxwell equations — unifying electricity, magnetism, and light as a single electromagnetic field — the greatest theoretical achievement in physics between Newton and Einstein.

Core Contribution

Unified electricity, magnetism, and light in four equations — predicting that light is an electromagnetic wave, predicting the existence of radio waves, and creating the mathematical framework that Einstein called the most profound in physics — single-handedly creating the theoretical foundation for modern communications technology.

Key Spikes & Highlights

  • Maxwell's Demon (devised a famous thought experiment — a tiny demon controlling a molecular door — that appeared to violate the second law of thermodynamics, launching a century-long debate about the relationship between information and entropy)
