The calculus of variations is a beautiful subject with a rich
history and with origins in the minimization problems of calculus. Although
it is now at the core of many modern mathematical fields, it does not
have a well-defined place in most undergraduate mathematics
curricula. This volume should nevertheless give the undergraduate
reader a sense of its great character and importance.

Interesting functionals, such as area or energy, often give rise to problems
for which the most natural solution occurs by differentiating a one-parameter family of
variations of some function. The critical points of the functional are related
to the solutions of the associated Euler-Lagrange equation. These differential
equations are at the heart of the calculus of variations and its applications
to other subjects. Some of the topics addressed in this book are Morse theory,
wave mechanics, minimal surfaces, soap bubbles, and modeling traffic flow. All
are readily accessible to advanced undergraduates.

This book is derived from a workshop sponsored by Rice University. It
is suitable for advanced undergraduates, graduate students and
research mathematicians interested in the calculus of variations and
its applications to other subjects.

#### Readership

Undergraduates, graduate students and research mathematicians interested in the calculus of variations and its applications to other subjects.

#### Reviews & Endorsements

This is a nice little book on many levels. The exposition is entertaining, the interplay between the mathematics and the applications is interesting, and the idea of 'advertising' higher mathematics to undergraduates and graduate students seems exciting and productive.

-- MAA Reviews

The book is recommended to an audience of undergraduate students as well as to teachers looking for inspiration for their own lectures.

-- EMS Newsletter

This work is a beautiful collection of six papers written by well known specialists in the Calculus of Variations. ... All these papers are very well written and they illustrate the fruitful interplay between pure and applied mathematics.
