商品描述

In this intriguing book, John Barnes takes us on a journey through aspects of numbers much as he took us on a geometrical journey in Gems of Geometry. Similarly originating from a series of lectures for adult students at Reading and Oxford University, this book touches a variety of amusing and fascinating topics regarding numbers and their uses both ancient and modern.

The author informs and intrigues his audience with both fundamental number topics such as prime numbers and cryptography, and themes of daily needs and pleasures such as counting one's assets, keeping track of time, and enjoying music. Puzzles and exercises at the end of each lecture offer additional inspiration, and numerous illustrations accompany the reader. Furthermore, a number of appendices provides in-depth insights into diverse topics such as Pascal's triangle, the Rubik cube, Mersenne's curious keyboards, and many others. A theme running through is the thought of what is our favourite number.

Written in an engaging and witty style and requiring only basic school mathematical knowledge, this book will appeal to both young and mature readers fascinated by the curiosities of numbers.

商品描述(中文翻譯)

在這本引人入勝的書中，約翰·巴恩斯（John Barnes）帶領我們探索數字的各個面向，就如同他在《幾何的瑰寶》（Gems of Geometry）中帶領我們進行幾何之旅一樣。這本書同樣源自於他在雷丁大學（Reading）和牛津大學（Oxford）為成人學生所做的一系列講座，觸及了許多有趣且迷人的主題，關於數字及其古今用途。

作者以基本的數字主題，如質數（prime numbers）和密碼學（cryptography），以及日常需求和樂趣的主題，如計算資產、記錄時間和享受音樂，來啟發和吸引讀者。每個講座結尾的謎題和練習提供了額外的靈感，並且有許多插圖伴隨著讀者。此外，數個附錄深入探討了各種主題，如帕斯卡三角形（Pascal's triangle）、魔方（Rubik's cube）、梅森奇特鍵盤（Mersenne's curious keyboards）等。貫穿全書的主題是我們最喜愛的數字是什麼。

這本書以引人入勝且機智的風格撰寫，只需基本的學校數學知識，將吸引對數字的奇趣感到著迷的年輕和成熟讀者。

作者簡介

Dr Barnes' principal achievements have been in the area of computer programming language design. He designed the language RTL/2 whilst with ICI. This was widely used in the 1970s and 80s for process control in the UK, the Netherlands and South Africa. The first ticket barrier system on the London Underground was an early example. He was a member of the Ada language design teams. Ada is widely used in safety critical applications such as those found in defence systems generally, avionics, air traffic control and railroad signalling. He has published twelve books: RTL/2 Design and Philosophy (1976); Programming in Ada (1982); Programming in Ada 95 (1996); High Integrity Ada (1997); Ada 95 Rationale (1997); High Integrity Software (2003); Programming in Ada 2005 (2006); Ada 2005 Rationale (2008); Gems of Geometry (2009); SPARK (2012); Ada 2012 Rationale (2013); Programming in Ada 2012 (2014). "Programming in Ada" went through four editions and was translated into six languages.
Dr Barnes has published many papers and given many lectures and tutorials on various aspects of programming. Although moving towards retirement he still gives occasional lectures including lectures for postgraduate courses. He has recently rediscovered an interest in mathematics and has given a number of popular courses at the Universities of Reading and Oxford as part of their Continuing Education programs; Gems of Geometry (now in a second edition) is based on one set of these courses.

作者簡介(中文翻譯)

巴恩斯博士的主要成就集中在計算機程式語言設計領域。他在ICI工作期間設計了RTL/2語言。這種語言在1970年代和1980年代廣泛用於英國、荷蘭和南非的過程控制。倫敦地鐵的第一個票閘系統就是一個早期的例子。他是Ada語言設計團隊的成員。Ada廣泛應用於安全關鍵的應用程序，例如一般的防禦系統、航空電子學、空中交通控制和鐵路信號系統。他已出版十二本書籍：RTL/2 Design and Philosophy（1976年）；Programming in Ada（1982年）；Programming in Ada 95（1996年）；High Integrity Ada（1997年）；Ada 95 Rationale（1997年）；High Integrity Software（2003年）；Programming in Ada 2005（2006年）；Ada 2005 Rationale（2008年）；Gems of Geometry（2009年）；SPARK（2012年）；Ada 2012 Rationale（2013年）；Programming in Ada 2012（2014年）。《Programming in Ada》經歷了四個版本，並被翻譯成六種語言。

巴恩斯博士發表了許多論文，並就程式設計的各個方面進行了多次講座和教程。儘管逐漸接近退休，他仍然偶爾進行講座，包括研究生課程的講座。他最近重新發現了對數學的興趣，並在雷丁大學和牛津大學的繼續教育計劃中開設了一系列受歡迎的課程；《Gems of Geometry》（現在已進入第二版）就是基於這些課程的一組內容。
