乔治·波利亚（George Polya，1887—1985)，美国数学家和数学教育家。生于匈牙利布达佩斯。1912年获布达佩斯大学博士学位。1914年至1940年在瑞士苏黎世工业大学任数学助理教授、副教授和教授，1928年后任数学系主任。1940年移居美国，历任布朗大学和斯坦福大学的教授。1976年当选美国科学院院士。还是匈牙利科学院、法兰西科学院、比利时布鲁塞尔哲学科学院和美国艺术和科学学院的院士。其数学研究涉及复变函数、概率论、数论、数学分析、组合数学等众多领域。1937年提出的波利亚计数定理是组合数学的重要工具。长期从事数学教学，对数学思维的一般规律有深入的研究，著有《怎样解题》《数学的发现》《数学与猜想》。

A perennial bestseller by eminent mathematician G. Polya, "How to Solve It" will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can be of help in attacking any problem that can be "reasoned" out - from building a bridge to winning a game of anagrams. Generatio...(展开全部)

A wide-ranging take on why humans have a troubled relationship with being an animal, and why we need a better one Human are the most inquisitive, emotional, imaginative, aggressive, and baffling animals on the planet. But we are also an animal that does not think it is an animal. How well do we really know ourselves? How to Be Animal tells a remarkable story of what it means to...(展开全部)

Humans are the most inquisitive, emotional, imaginative, aggressive and baffling animals on the planet. But how well do we really know ourselves? How to Be Animal writes a remarkable story of what it means to be human and argues that at the heart of our psychology is a profound struggle with being animal. As well as piecing together the mystery of how this psychology evolved, t...(展开全部)

Proofs play a central role in advanced mathematics and theoretical computer science, and this bestselling texts' third edition will help students transition from solving problems to proving theorems by teaching them the techniques needed to read and write proofs, with a new chapter on number theory and 150+ new exercises.

This is a new and revised edition of a book which has already established itself as a basic text in social theory. The first section of the work provides a concise critical analysis of some leading schools of thought in social philosophy, giving particular attention to phenomenology, ethnomethodology and Wittgensteinian thought. Giddens concentrates primarily upon the implicat...(展开全部)
