The Quantum World, a free science course on Tomo

The Quantum World

Discover the strange rules that govern the universe at its smallest scale. Learn why particles can be in two places at once and how this 'weird' science powers your smartphone.

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.

24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Breaking the Rules of Reality; Waves, Particles, and Uncertainty; The Power of Observation; and Quantum Physics in Your Pocket. It starts from scratch.

What you'll learn

Key ideas in The Quantum World

  • Energy is not a smooth stream but is made of individual units called quanta
  • Electrons disappear from one state and reappear in another instantly
  • You cannot have 'half' of a fundamental energy packet
  • There is no 'travel time' or intermediate path during a quantum leap
  • The total energy is always a multiple of these base packets
  • The transition is an all-or-nothing jump between fixed positions
  • Energy as discrete packets
  • The instantaneous nature of a quantum leap
  • The universe has a 'minimum resolution' beyond which things aren't smooth
  • Classical physics (Newtonian) works for large objects but fails at the atomic scale
  • The concept of energy as discrete packets (quanta) versus a continuous flow
  • At the macro scale, the graininess is hidden because the 'pixels' are so small
  • Quantum effects are only noticeable when dealing with the very small
  • Nature behaves like a digital screen rather than an analog painting
  • Quantum particles do not have a single definite location until measured
  • The 'pixelated' nature of the universe at the smallest scale
