Sommario/riassunto

Olympiad mathematics is not a collection of techniques of solving mathematical problems but a system for advancing mathematical education.  This book is based on the lecture notes of the mathematical Olympiad training courses conducted by the author in Singapore. Its scope and depth not only covers and exceeds the usual syllabus, but introduces a variety concepts and methods in modern mathematics.  In each lecture, the concepts, theories and methods are taken as the core. The examples are served to explain and enrich their intension and to indicate their applications. Besides, appropriate num

Sommario/riassunto

"In Anatomy of Failure, Harlan Ullman asserts that presidents and administrations have consistently failed to use sound strategic thinking and lacked sufficient understanding of the circumstances prior to deciding whether or not to employ force. He analyses the records of presidents from John F. Kennedy to Barack Obama and Donald Trump in using force or starting wars. His recommended solutions begin with a "brains-based" approach to sound strategic thinking to address one of the major causes of failure--the inexperience of too many of the nation's commanders-in-chief. Ullman reinforces his argument through the use of autobiographical vignettes that in some cases making public previously unknown history."--Provided by publisher.
