Region
Matter & Energy
Physics and chemistry: forces and motion, electricity, light, heat and atoms. The rules behind how everything around us behaves.
Matter & Energy covers physics and chemistry: how things move and why, electricity and magnetism, light and sound, heat, and what matter is made of.
Branches of this region
21 of 24 topics in this region are written so far. The rest are uncharted: on the map, but not yet written. The Atlas is growing.
- MechanicsThe branch of physics that explains how and why things move: forces, motion, momentum and energy, from falling objects to orbiting planets.4 branches
- Electricity & MagnetismElectric charge, current, magnets and induction: the linked forces behind every circuit, motor and power station.3 branches
- Light & WavesWhat waves are, how sound travels, the electromagnetic spectrum from radio waves to gamma rays, and how light reflects, bends and interferes.
- Heat & ThermodynamicsHeat, temperature and the four laws of thermodynamics: how heat moves, why no engine is perfect, and how fridges and heat pumps work.
- Atoms & Chemistry
- Modern Physics
