The Quantum World, a free science course on Tomo

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.

What you'll learn

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

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.
