Path integral theory explained by its inventor
on 11 November 1996
The path integral technique of quantum physics is used
in nearly all of modern physics, ranging from astrophysics
to condensed matter theory. In this book, the author and
developer of path integrals, R.P.Feynman, provides us with
a unique insight into this theory and its applications in
the various fields of physics.
The first few chapters present Feynman's view on the
fundamental concepts underlying quantum mechanics. From
this intuitive view, path integrals are introduced.
Later chapters cover more advanced topics like the
perturbation method, quantum electrodynamics and the
relation of path integrals to statistical mechanics.
Most books on quantum mechanics tend to drown the
underlying physics in a sea of mathematics. Feynman
however, presents his celebrated theory in a clear,
concise way, keeping the perfect balance between
mathematics and physical insight. Definitely a book
anyone interested in quantum physics should keep
under his or her pillow !
