Heisenberg's Uncertainty

For 2,000 years, from Aristotle to Newton, we believed the universe was precise. If you measured it well enough, you knew it. In 1927, Werner Heisenberg proved this was impossible. He showed that at the quantum scale, nature is fuzzy. The more you focus on a particle's position (x), the more its momentum (p) blurs. You cannot know both. This isn't because our instruments are bad; it's because the universe does not have a precise state until it is forced to choose. The inequality `Δx·Δp ≥ ℏ/2` is the tombstone of the Clockwork Universe.

This simple formula killed Laplace's Demon (see 008-007). The Demon relied on knowing the current state of every particle to predict the future. Heisenberg showed that the 'current state' is fundamentally unknowable with perfect precision. If you can't know the present, you can't calculate the future. Causality at the micro-level is not a rigid chain; it is a roll of the dice. Einstein hated this ('God does not play dice'), but the math held.

Uncertainty implies that the act of observation changes the observed. To 'see' an electron, you must bounce a photon off it. That photon hits the electron and changes its path. We are not outside the fishbowl looking in; we are in the water. Every measurement is an interference. This connects back to the Oracle Bones (008-006)—the realization that to read the future is to alter it.
