The five lectures are about:
1. The development of quantum mechanics.
2. Quantum electrodynamics.
3. Magnetic monopoles.
4. A positive energy, relativistic wave equation.
5. Cosmology and the gravitational constant.
In my opinion, Dirac is one of the greatest physicist ever. This book gives a unique insight his way of doing science, in which mathematical beauty plays an important role.
Lecture #1 is also very nice because Dirac has experienced much of the development of quantum mechanics himself, making him an authority on the area.

This book is fairly easy to read and understand. It is not too technical. It includes articles that are ethical in nature, and those that are mathematical and quantitative. This is an excellent introduction for anyone interested in discount rates, project evaluation, cost-benefit analysis, and equity among generations.
