Numbers are an important feature of almost all known cultures. In this detailed anthropological study, Thomas Crump examines how people from a wide range of diverse cultures, and from different historical backgrounds, use and understand numbers. By looking at the logical, psychological and linguistic implications, he analyses how numbers operate within different contexts. The a...(展开全部)

This volume is a window on a period of rich and illuminating philosophical activity that has been rendered generally inaccessible by the supposed "revolution" attributed to "Analytic Philosophy" so-called. Careful exposition and critique is given to every serious alternative account of number and number relations available at the time.

In a grand and immemsely readable synthesis of historical, political, cultural, and economic analysis, a prize-winning historian depicts much more than a break with England. He gives readers a revolution that transformed an almost feudal society into a democratic one, whose emerging realities sometimes baffled and disappointed its founding fathers.

Because evolution endowed humans with a complement of ten fingers, a grouping size of ten seems natural to us, perhaps even ideal. But from the perspective of mathematics, groupings of ten are arbitrary, and can have serious shortcomings. Twelve would be better for divisibility, and eight is smaller and well suited to repeated halving. Grouping by two, as in binary code, has tu...(展开全部)

古斯塔夫·勒庞(Gustave Le Bon，1841-1931) 法国著名社会心理学家。他自1894年始，写下一系列社会心理学著作，以本书最为著名，被 翻译成近二十种语言，至今仍在国际学术界有广泛影响。 勒庞认为，现代生活逐渐以群体的聚合为特征，在《乌合之众》一书中，他指出，个人一旦进入群体中，他的个性便湮没了，群体的思想占据统冶地位，而群体的行为表现为无异议，情绪化和低智商。

蔡天新编著的《数之书》是一本有关整数（有时也涉及有理数）的书，是每一位受过中等或高等教育的人都能看懂或部分看懂的书。本书共有7章，内容包括：整除的算法、同余的概念、同余式理论、平方剩余、n次剩余、整数幂模同余和加乘数论等。前5章及其补充读物仍构成《初等数论》的教学内容，最后两章不在此课程的讲授范围之内，但第6章与同余式紧密相关，且能够伸手触摸到。至于本书的最大特色，可能要数每节后面的补充读物。这种形式是一种尝试，希望借此拓广读者的知识面和想象力，递增他们对数论的兴趣和热爱。本书可供数学及相关专业的教师、学生阅读参考，也可供数学爱好者自学使用。
