If there is a branch of mathematics that "embodies" its relationship with physics and the engineering sciences in a exemplary manner, it is none other than Differential Equations.

This book draws its mathematical standards from the brilliant tradition that this relationship has created. The non-formalistic spirit, the emphasis on intuitive and qualitative understanding, the elegance and efficiency of the methods, are some elements of this tradition that shape the character of the book and partly explain its warm reception by the educational community.

With its plethora of applications, the 180 solved examples, and the approximately 800 unsolved problems along with their answers, this book is particularly suitable not only as a teaching aid but also as a guide for purely personal study. A truly new book on an old, yet always relevant, topic.
