Chapter 02 of 5

Enter the Demon

Maxwell’s tiny gatekeeper attempts a logic-defying feat.

  1. The Challenger

    A Mind for Molecules

    In 1867, James Clerk Maxwell imagined a tiny, intelligent being capable of seeing individual molecules. He designed this creature specifically to test the limits of the Second Law.

  2. The Setup

    The Divided Chamber

    Imagine a sealed box divided into two compartments by a wall. A small, frictionless door connects the two sides, controlled by our imaginary observer.

  3. Molecular Chaos

    The Speed Distribution

    Inside the box, molecules move at various speeds. Some are fast (hot) and others are slow (cold), colliding randomly in a state of high entropy.
