The Quantum World
Like Duolingo, but for The Quantum World. 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.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Breaking the Rules of Reality and The Connected Universe. It starts from scratch.

Key ideas in The Quantum World
- Nature has a minimum 'pixel' size that cannot be split
- Energy is delivered in discrete packets rather than a continuous flow
- Particles like electrons do not sit at a specific point
- Subatomic objects exist as a 'cloud' or wave of possible locations
- The act of looking or measuring is what forces a particle to 'choose' one spot
- Understanding that reality is 'grainy' rather than continuous
- The concept that particles lack a single fixed position until measured
- Quantum events are governed by chance, not set-in-stone paths
- We can calculate the percentage chance of an outcome, but never the outcome itself for one particle
- The weirdness of quantum mechanics 'washes out' as objects get larger
- Common sense rules like 'an object is in one place' only emerge when billions of particles work together
- Distinguishing between the rules of the quantum world and the everyday world
- A particle exists in all possible configurations at once before observation
- The shift from deterministic 'clockwork' physics to probabilistic outcomes
- Measurement 'collapses' the particle into one specific state
- The state is not a blend or a midpoint, but a collection of possibilities
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 The Quantum World 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.
