| Chapter | |||
|---|---|---|---|
| 1. | Conservation of Energy | Energy is never created or destroyed, only converted between kinetic and potential forms | ⚛ |
| 2. | Conservation of Momentum | Total momentum of an isolated system is constant, even through collisions | ⚛ |
| 3. | Conservation of Angular Momentum | Spinning things keep spinning unless a torque acts on them | ⚛ |
| 4. | Thermodynamics | Entropy always increases, and that arrow of time constrains every engine | ⚛ |
| 5. | Waves | Waves superpose, interfere, and decompose into Fourier components | ⚛ |
| 6. | Electricity | Charges create fields, fields do work, and circuits are the plumbing | ⚛ |
| 7. | Magnetism | Moving charges create magnetic fields; magnetic forces are always perpendicular to velocity | ⚛ |
| 8. | Electromagnetism | Changing electric fields create magnetic fields and vice versa: Maxwell's equations | ⚛ |
| 9. | Optics | Light is an electromagnetic wave: reflection, refraction, diffraction | ⚛ |
| 10. | Relativity | Space and time are one fabric; nothing outruns light | ⚛ |
| 11. | Quantum Mechanics | Particles are waves of probability; measurement collapses the wavefunction | ⚛ |
| 12. | The Atom | Quantum mechanics explains the periodic table, spectral lines, and chemical bonds | ⚛ |
