The Measurement Problem
The logical crisis: why does looking at something change what it is?
- The Great Wall
Where Math Fails
The Schrödinger equation describes smooth waves, but reality shows us sharp, distinct particles. The jump from one to the other is the measurement problem.
- Wave Collapse
Sudden Disappearance
When we look, the broad range of possibilities 'collapses' into a single outcome. Physics doesn't yet explain how this happens.
- The Mystery
The Missing Link
Quantum math works perfectly for atoms, and classical math works for cats. There is no math for the transition between them.
