David Tong -- Cambridge Lecture Notes on Theoretical Physics

David Tong: Lectures on Theoretical Physics


Dynamics and Relativity

An introduction to Newtonian Mechanics and Special Relativity, aimed at first year undergraduates.

[Lagrange Points]

Classical Dynamics

A second course on classical mechanics, covering the Lagrangian and Hamiltian approaches, together with a detailed discussion of rigid body motion.



An introduction to electromagnetism, starting from the Maxwell equations and describing their application to electrostatics, magnetostatics, induction and light. The course also covers the relativistic form of the equations.


Statistical Physics

An introduction to statistical mechanics and thermodynamics, aimed at final year undergraduates. After developing the fundamentals of the subject, the course covers classical gases, quantum gases and phase transitions.

Kinetic Theory

A graduate course on basic topics in non-equilibrium statistical mechanics. It covers kinetic theory and the Boltzmann equation, stochastic processs and linear response.


Quantum Field Theory

An introductory course on quantum field theory, aimed at first year graduate students. It covers the canonical quantization of scalar, Dirac and vector fields. Videos are also included.


String Theory

An introduction to string theory, aimed at first year graduate students. It covers the bosonic string and the basics of conformal field theory.



A course for advanced graduates students, covering solitons in supersymmetric gauge theories and D-branes. It was given at the TASI summer school.
