The Second Law

The arrow from which everything flows

ΔS ≥ 0

For macroscopic isolated systems

LOW ENTROPY

Ordered, concentrated

Few microstates

PARTICLE DISPERSAL

From grid toward equilibrium

Explore the changing spread

Initial grid Dispersal proxy: 0% Equilibrium spread

An illustrative dispersal proxy, not a measurement of thermodynamic entropy. The meter averages distance from the initial grid and scales it to the expected equilibrium spread. It can fluctuate in either direction.

Particles spreading away from the initial grid

WHAT THE SECOND LAW ESTABLISHES

• The arrow of time — past differs from future
• Irreversibility — some changes cannot be undone
• The drive to spread — energy disperses, differences equilibrate

Everything in The Deeper Law begins here. Local order can grow while the combined entropy of a system and its surroundings increases. The book asks what this permits, and where the analogy to coordination reaches its limits.
