书桌上的新版的《数学花园漫游记》勾起了我对往事的回忆。我从小对数学挺感兴趣的,喜欢读数学书。但当时家里比较穷,也想不到买什么书,《数学花园漫游记》是从何而来,我已经记不得了。但我清晰地记得,当我翻开书,读到第一章数数问题时,就被那个如何估计池塘中的鱼数的问题深深迷 The new version of “Mathematical Garden Walkthrough” on my desk brought back memories of the past. I was very interested in math, like to read math books. But at that time, the family was poorer and could not think of buying any books. The Mathematical Garden Walk is from wherever I can not remember.
