entropy
Disorder increases over time. Energy dissipates. Systems tend toward equilibrium. Maintenance is the default cost of existence—order requires constant input.
key principles
- 01
Disorder is the default
Left alone, organized systems decay. Rooms get messy. Relationships drift. Bodies age. Entropy is the arrow of time.
- 02
Order requires energy
Maintaining organization demands continuous input. The moment you stop investing, decay begins.
- 03
Heat death is the destination
Eventually, all energy spreads evenly—no gradients, no work possible. This is thermodynamic equilibrium.
- 04
Local order, global disorder
Life creates local pockets of order by exporting entropy elsewhere. We stay organized by making our environment less so.

The Arrow of Time
The second law of thermodynamics states that entropy—disorder—increases in any closed system. This is one of the most universal principles in physics, and it applies far beyond physics.
Everything tends toward decay. Not because decay is forced, but because there are so many more ways to be disordered than ordered. Order is improbable; disorder is probable. Time takes us from improbable to probable.
