Quantum Physics in Your Pocket
Discover how the strange rules of the subatomic world power your smartphone, heal your body, and define the future of technology.
Like Duolingo, but for Quantum Physics in Your Pocket. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
79 levels across 8 sections, about 158 minutes end to end, roughly 32 days at five minutes a day. It moves through The Invisible Engine, The Weird Rules of Reality, Quantum Shortcuts, Life is Quantum, The Digital Revolution, Modern Medicine, The Future of Power, and The Quantum Horizon. It starts from scratch.

Key ideas in Quantum Physics in Your Pocket
- Classical physics predicts electrons should move like continuous water, not discrete packets
- Quantum energy gaps allow a material to switch between conducting and insulating
- Modern electronics require the precise control of individual subatomic particles
- Metals have no gap and are always 'on', while insulators have gaps too large to cross
- The fundamental limitation of classical physics in explaining modern electronics
- The role of energy gaps in semiconductor function
- Light behaves as individual particles called photons
- One photon hitting a sensor releases exactly one electron (the photoelectric effect)
- Quantum particles can pass through physical barriers that would stop a classical object
- Trapping electrons behind these barriers allows data to stay saved even when the power is off
- The process of digital image capture via light packets
- Color is determined by the specific amount of energy an electron loses
- Changing the physical size or structure of a material changes its available energy levels
- The mechanism of non-volatile flash memory
- How electron energy levels determine screen color
- In a laser, one photon triggers a 'clone' photon from an atom
