Susskind Classical Mechanics MOC
This map is the classical-mechanics spine of Susskind The Theoretical Minimum index. It follows the local Susskind classical mechanics reference PDF at a study-note level: no long quotations, just the ideas, equations, and traps Andrew is likely to need when revisiting the material.
One-sentence spine
Classical mechanics is the study of how a complete state moves through phase space, with equivalent languages built from Newton’s laws, stationary action, Hamiltonian flow, and conservation.
Lecture map
| Lecture | Note | Main question |
|---|---|---|
| 1 | Susskind Lecture 1 - Classical Mechanics | What is a state, and why should deterministic laws preserve information? |
| 2 | Susskind Lecture 2 - Motion | How do smooth trajectories encode velocity, acceleration, oscillation, and circular motion? |
| 3 | Susskind Lecture 3 - Classical Mechanics | How does Newton replace Aristotle by making force proportional to acceleration? |
| 4 | Susskind Lecture 4 - Systems of More Than One Particle | Why does an N-particle state live in 6N-dimensional phase space? |
| 5 | Susskind Lecture 5 - Energy | How do conservative forces come from a potential, and why is T + V conserved? |
| 6 | Susskind Lecture 6 - Principle of Least Action | How does one functional, the action, produce the equations of motion? |
| 7 | Susskind Lecture 7 - Symmetries and Conservation Laws | How does invariance of the Lagrangian generate conserved quantities? |
| 8 | Susskind Lecture 8 - Hamiltonian Mechanics | How do energy and time-translation symmetry lead to Hamilton’s equations? |
| 9 | Susskind Lecture 9 - Phase Space Fluid and Liouville Theorem | Why does Hamiltonian flow preserve phase-space volume? |
| 10 | Susskind Lecture 10 - Poisson Brackets and Angular Momentum | How do Poisson brackets package motion, symmetry generators, and angular momentum? |

Suggested study route
- Read Lectures 1-4 as the state-space setup: positions alone are not enough.
- Read Lectures 5-7 as the Lagrangian setup: energy, action, and symmetry.
- Read Lectures 8-10 as the Hamiltonian setup: phase-space flow and Poisson brackets.
- Read Lecture 11 as the bridge to electromagnetism and later quantum mechanics.
