This simple principle (and its variants and generalizations) applies to optics, mechanics, electromagnetism, relativity and quantum mechanics, and provides an essential guide to understanding the beauty of physics. This unique text provides an accessible introduction to the action principle across these various fields of physics and examines its history and fundamental role in science"-- ER -
