Quantum Physics for the Real World
Discover the strange rules that govern the smallest building blocks of our universe and how they power the technology in your pocket.
Like Duolingo, but for Quantum Physics for the Real World. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through The Quantum Surprise, The Rules of the Game, and Quantum Tech in Your Pocket. It starts from scratch.

Key ideas in Quantum Physics for the Real World
- Energy is not a smooth fluid but comes in discrete packets
- Large-scale 'classical' physics rules do not apply to atoms
- There is a 'smallest possible' amount of energy that cannot be divided further
- Subatomic particles do not move in simple, predictable lines
- The term 'quantum' refers to these individual, countable units
- Human intuition based on everyday objects is often wrong about the very small
- Light travels and interferes like a wave
- Light hits targets and transfers energy in concentrated lumps like a particle
- The concept of energy being 'quantized' rather than infinitely divisible
- The 'photon' is the name for the particle-like unit of light
- To see something, you must bounce light or energy off it
- The failure of classical intuition at the atomic scale
- At the quantum scale, the energy used to observe a particle is strong enough to push it
- The act of looking is a physical interaction that changes the result
- The dual nature of light
- The physical impact of measurement on a quantum system
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 Physics for the Real 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.
