Practicle physics and introduction to field theory

Lee T.D.

The intention of the course was to bring both theoretical and experimental students of physics to the forefront of this very exciting and active field. Because of the different backgrounds of those who attended my lectures, this book is self-contained. Whenever possible, I have adopted an approach that is more pragmatic than axiomatic. All derivations are done explicitly, which at times to o more sophisticated reader may appear pedantic.
