How Quantum Physics Works
Like Duolingo, but for How Quantum Physics Works. 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: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Rewriting the Rules of Light and Matter and The Bizarre Effects Shaping Our World. It starts from scratch.

Key ideas in How Quantum Physics Works
- Energy at the subatomic scale comes in distinct, indivisible packets called quanta
- You cannot exchange half a quantum of energy; it is an all-or-nothing delivery
- Everyday smooth energy transfers are an illusion caused by billions of tiny discrete packets blurring together
- Each incoming packet of light delivers energy based on its color (frequency), not the overall beam brightness
- A single high-energy photon (like violet or UV) has enough punch to eject an electron, while billions of low-energy red photons cannot combine their energy to do it
- Increasing brightness only adds more packets of the same energy, not stronger individual packets
- Electrons are restricted to specific, fixed energy levels (rungs) around the nucleus
- There is a lowest possible rung (the ground state) below which an electron cannot fall
- Because an electron cannot lose energy continuously, it cannot spiral into the nucleus and collapse matter
- Transitions between allowed states happen instantaneously rather than across a smooth path
- An electron is never found 'halfway' between two allowed energy rungs
- The size of the downward step an electron takes directly sets the exact color and wavelength of the emitted photon
- Because each element has a unique ladder of allowed rungs, each produces a unique set of sharp color lines (spectral fingerprint)
- Atoms do not glow in continuous rainbows; they glow at specific discrete wavelengths corresponding to their rung gaps
- Single particles still form a multi-striped wave interference pattern over time
- Each particle lands as a discrete dot, but the collective distribution shows alternating bands of high and low probability
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 How Quantum Physics Works 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.
