Quantum Mechanics and Reality
Examine what quantum theory actually reveals about the fabric of physical existence. Move past introductory pop-science paradoxes to evaluate how measurement, entanglement, and rival interpretations dismantle our classical assumptions about objective reality.
Like Duolingo, but for Quantum Mechanics and Reality. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 8 levels across 2 sections, about 16 minutes end to end, roughly 3 days at five minutes a day. It moves through Dismantling Classical Reality and Evaluating Quantum Ontologies. It assumes you already know the basics.

Key ideas in Quantum Mechanics and Reality
- Schrödinger evolution describes deterministic, continuous wave change.
- Measurement collapse invokes sudden, random jumps to definite values.
- Standard theory lacks a formal rule defining when collapse overrides evolution.
- The Von Neumann cut marks where linear quantum systems meet classical observers.
- Moving the cut along the measurement chain yields identical experimental probabilities.
- The mathematical placement of the cut is physically arbitrary within standard theory.
- Decoherence entangles a quantum system with surrounding environmental particles.
- Phase-damping rapidly suppresses observable quantum interference effects.
- Decoherence produces an apparent mixture but leaves the selection problem unsolved.
- Wigner models his friend and the apparatus together as one combined quantum wave.
- The inside friend experiences a single definite result before Wigner opens the lab.
- The experiment proves facts can be relative to observers in unitary quantum mechanics.
- EPR assumed local realism: nothing travels faster than light and distant objects have pre-existing states.
- Predicting a distant particle's measurement with certainty implies an objective 'element of physical reality'.
- Because standard quantum mechanics lacks variables for these predetermined states, EPR called it incomplete.
- Bell showed that local realism sets a strict mathematical cap on correlations across different detector angles.
