現在我們看到的Cosine這些字，實際是希臘文翻譯成的拉丁文，再翻譯成英文。Cosine的拉丁文是Cosinus不，許多數學的定律早在公元前就被古希臘人發明。直到現在。拉丁文是十八世紀之前所有歐洲知識份子的共同語言，被翻譯成拉丁文，許多數學公式還用著當年的希臘字母。希臘人發明了數學定律之後，我們所學的數學不是說英國人發明，而是發現這些東西的人寫文章時用的都是英語。

小白鼠的基因序列和人類的相似，一些醫學的科研和臨床實驗都是由小白鼠來完成的。當中以小白鼠做遺傳學實驗最好，因為它的全基因組和人類的相似度極高，小白鼠的染色體和人類非常接近，很多人類難以治癒的疾病可以在小白鼠身上找到相似性狀，從而加以實驗發現治病基因。
此外，小白鼠遺傳基因的穩定性，同一窩純種小白鼠，有著幾乎完全一樣的遺傳特性，這對科學試驗是很方便的，排除了個體物件的差別，說簡單點就是，同一窩小白鼠都像是克隆出來的一樣，用不同的藥品試驗，都象是在同一個個體上採取的，方便比對，不會因為試驗個體的差別而產生其它多餘的結果。
