沒錯,跟我的想法差不多!我是把x、y座標互乘,計算變號次數,要算四次。而脫離速度,我是以速度的點積及 2/r 來比較,自認可以降低浮點數誤差。我們方法不同,但結果相同!

這的確覆蓋很多東西。我原意是想要將各式學科結合在一起,而不要死板板地限制在一個領域之中。在學校,老師大都侷限於自己專門的領域中授課,各個科目沒什麼交集。這樣感覺不怎麼好,就好比一隻魚被大卸八塊卻不鮮美可口,成了屍塊一般。老實說,學科並非涇渭分明而有個明確的界線,若肯努力去探索,必定可以找到它們的異同處。
台灣最近在鼓吹程式教育,希望整個教育體系能好好納入程式設計。這想法本身不錯,自己也樂觀如是發展,但擔心會流於形式,而失去其中的真諦。
所以我才寫這系列,想作為一個範本供他們參考。這一篇文章本身就是高中領域內的東西來做發揮,行星運行、牛頓力學、向量,沒有超出範圍,如果是好好學習的高中生,應並不難理解當中的理論。這樣一來,在授課的同時便可以結合程式設計,一同學習,不一定要特別開一門資訊課來教導。
不過,我是期望大家都可以學習,好好地體會當中的奧妙啦!只可惜這系列難度有點高,算是一個遺憾。
