Quantum Reality
Like Duolingo, but for Quantum Reality. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.

Key ideas in Quantum Reality
- There is a minimum 'step' or size below which things cannot be divided
- Energy transfer happens in specific, countable amounts
- Physical reality is made of distinct building blocks rather than a perfectly smooth, infinite slope
- A 'quantum' is the smallest possible unit of a physical entity
- The concept of a 'pixelated' universe at the smallest scales
- Understanding that energy is delivered in discrete packets
- Subatomic particles don't have a single fixed position until they interact with something
- Superposition allows for multiple states to exist simultaneously
- The act of looking or measuring forces the particle to 'choose' a single state
- Observation collapses the multiple possibilities into one reality
- The concept of superposition in subatomic objects
- The effect of observation on a quantum system
- Quantum math doesn't tell you what *will* happen, only the percentage chance of it happening
- The 'clockwork' universe where every cause has a single certain effect does not apply at the atomic scale
- Probability vs. predictability in the quantum realm
- Classical theory predicted that higher frequencies of light would carry more energy without limit
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Quantum Reality the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
