具體描述

內容簡介

A funny, entertaining introduction to Ben Franklin and his many inventions, including the story of how he created the "magic square." A magic square is a box of nine numbers arranged so that any line of three numbers adds up to the same number, including on the diagonal! Teachers and kids will love finding out about this popular teaching tool that is still used in elementary schools today!

精彩書評

"In this lively offering from the Step into Reading + Math series, young readers will learn about both Benjamin Franklin and magic squares--square grids of numerals in which all the numbers in any vertical, horizontal, or diagonal row adds up to the same sum. The text introduces Franklin as a smart, curious kid whose ideas led him to "inventing cool things"; as a witty, intelligent man whose ideas were the seeds of America's first library, fire station, and hospital; and as a "super busy guy" who amused himself during meetings of the Pennsylvania Colonial Assembly by creating magic squares. An appended section offers step-by-step directions for those who want to construct their own versions of the mathematical puzzle. The engaging, informal style of the writing and the colorful, cartoonlike illustrations make this a playful but solid choice for introducing young readers to Franklin and to magic squares."

古人雲:“書中自有黃金屋,書中自有顔如玉。”可見,古人對讀書的情有獨鍾。其實,對於任何人而言,讀書最大的好處在於:它讓求知的人從中獲知,讓無知的人變得有知。讀史蒂芬?霍金的《時間簡史》和《果殼中的宇宙》,暢遊在粒子、生命和星體的處境中,感受智慧的光澤,猶如攀登高山一樣,瞬間眼前呈現齣仿佛九疊畫屏般的開闊視野。於是,便像李白在詩中所寫到的“廬山秀齣南鬥旁,屏風九疊雲錦張,影落明湖青黛光”。
