David Tong is a Professor of Theoretical Physics at the University of Cambridge and a Fellow of Trinity College. He is known for his contributions to quantum field theory and its application to diverse areas of physics, including particle physics, condensed matter, cosmology, and quantum gravity. His lecture notes on theoretical physics have gained a global following due to their clear explanations and easy-going, accessible style.

• 1. Newtonian Mechanics; 2. Forces; 3. Interlude: Dimensional Analysis; 4. Systems of Particles; 5. The Two-Body Problem; 6. Rotating Reference Frames; 7. The Lagrangian Formalism; 8. Small Oscillations; 9. Rigid Bodies; 10. The Hamiltonian Formalism; 11. Special Relativity.

'This is theoretical physics 'done right'. The author's love of the subject and its history, as well as its results, shines through. The definitions and derivations are clean, but never dry. For students of modern physical science, these volumes will be a rich source of instruction, insight - and joy.' Frank Wilczek, Massachusetts Institute of Technology
