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.



A course on electromagnetism, starting from the Maxwell equations and describing their application to electrostatics, magnetostatics, induction, light and radiation. The course also covers the relativistic form of the equations and electromagnetism in materials.


Applications of Quantum Mechanics

An advanced course on quantum mechanics, aimed at final year undergraduates. It covers the basics of condensed matter physics and scattering theory and a number of other topics.


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.


Quantum Hall Effect

An introductory course to the quantum Hall effect. The first half uses only quantum mechanics and is at a level suitable for undergraduates. The second half covers more advanced field theoretic techniques of Chern-Simons and conformal field theories.


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.

Concepts in Theoretical Physics

A handful of lectures aimed at first year undergraduates, each focussing on a different topic in theoretical physics.
