The Three Laws of Thermodynamics are fundamentally downers:
- Energy can neither be created nor destroyed. It can only change forms.
- The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.
- As temperature approaches absolute zero, the entropy of a system approaches a constant minimum.
It can help to put them in joke form:
- You can’t win, you can only break even.
- You can only break even at absolute zero.
- You can never reach absolute zero.
