第四百六十七章 九章算术
最新网址：m.ltxsdz.com
“九章算术”公孙俶也是接过了一本九章算术，先前林玧琰也是说过，周公制礼而有九数，九数之流则九章是矣，故此博学多才的公孙俶也是知晓九章算术听其书名便是已经知晓乃是一本数理之作。
众人知晓此时公子琰拿出来九章算术一定不是无的放矢，一一观览起来，秦国的士子已经是接纳了“白纸”作为书写工具的存在，但是郑地士子还是认为竹简和帛书才是文人士子书写的正统，到了秦国，虽是好奇白纸乃是如何制造的，但因为其低廉的价格流行在寒门士子之中，那些郑地士子也是将白纸归拢于最为下品的书写材料之一。
造纸术和印刷术在如今的大秦还是属于秘密，林玧琰的心腹孔宣如今还是在竹山邑造着纸张，这数年间大秦的战事着实不在少数，也是让林玧琰忽视了造纸术和印刷术的作用。
林玧琰也是在众人看的七七八八的时候，解释道“九章算术拢共包括方田、粟米、衰分、少广、商功、均输、盈不足、方程及勾股等九个方面，乃是数理集大成之作。”
“鞭辟入里，发人深省”公孙俶也是给出来了极高的评价，这九章算术之中的数理运算，乃是结合实际选出来的例子，虽说旁边列出来了一些蝌蚪文字，让公孙俶看不懂，但公孙俶也是看出来了，那蝌蚪文字不过只有数十种，只要运用得当，便是能够以最短的速度掌握这九章算术之中的精髓。
“的确是数理集大成之作”谷梁丘也是点了点头，这么多年来，谷梁丘一直钻研儒家经学之作，数理接触的也是比较少，但并不是没有接触，就谷梁丘所知，那位南阳书院出身的师弟，如今大秦司空、南郡守明子夫便是在数理一学上有着独到的天赋。
尤其是方才林玧琰已经是明指出来了，这九章算术乃是源自姬周王朝初期的那位鲁国太公周公旦“周公制礼而有九数，九数之流则九章是矣。”
恰巧这位周公旦也是儒家学说推崇的先贤之一，更何况但凡是能够为吏者，甚至是领政一方的郡守，皆是要掌握一定的数理，如此方能够更好的调度，治理地方也是井然有序，不至于乱了套子。
先天上，这本九章算术在谷梁丘看来就是属于儒家之作。
“暂且不论南阳学宫如何，大秦的乡邑已经是陆陆续续开办了名为私塾的讲学启蒙之地，除了宣传大秦的法治之外，则是需要教授乡邑子弟读书认字，倒不如从这九章算术之中挑出来一些浅显易懂的数理教授乡邑子弟，如何”
有教无类已经是成为了中原士子的共识，真是一度还产生了“肉食者鄙”的观点，教授乡邑子弟以数理并非是难以接受。
但是这些士子已经是察觉到了九章算术之中的珍贵之处，不过碍于对上面的蝌蚪文字并不熟识，故此不便看懂罢了，是故也是有着士子站起来请求公子琰教授这九章算术之上的蝌蚪文字。
林玧琰笑了笑，这些士子看不懂的蝌蚪文字不过是后世简简单单的阿拉伯数字罢了，至于其他的不过只是一些数学运算之中的常用符号罢了，并不难理解，林玧琰不过是花了半个时辰，一一详细解释清楚，场中便是有着聪慧者完全领悟了其中的意思。
“未曾料到勾股尚还能够如此推算”
“方程也是极为巧妙，简直难以想象数理之中还能够隐藏着如此玄妙的东西”
林玧琰的视线一一扫过这些沉浸在数理巧妙的士子，也是勾起来了嘴角，数千年积攒起来的数理常识此时此刻爆发式的展现在这些士子的面前，岂会是没有丝毫的诱惑
“如此一来，倒是好将这些士子引入局了”
