斯蒂格勒定律例子列表

斯蒂格勒定律（Stigler's law），又稱名字命名法則。是芝加哥大學一位很有幽默感的統計學家史蒂芬·史蒂格勒提出的一定律，最簡單的說法是「沒有科學的發現是因其原有發現者的名字而命名」，即科學定律最後的命名大多歸功於後來更有名望的科學家。斯蒂格勒自己認為斯蒂格勒定律其實是羅伯特·金·莫頓最先發現，因此「斯蒂格勒定律」本身的命名也符合斯蒂格勒定律。

著名示例包括：

- 高斯分佈：最早是由棣莫弗在1718年著作中提出。
- 本福特定律：最早是由西蒙·紐康在1881年提出。
- 三次方程的卡爾達諾公式：解法的思路來自塔塔利亞。
- 歐拉數e：雅各布·伯努利第一個注意到此常數。
- RSA加密演算法：RSA是1977年由羅納德·李維斯特（Ron Rivest）、阿迪·薩莫爾（Adi Shamir）和倫納德·阿德曼（Leonard Adleman）一起提出的。當時他們三人都在麻省理工學院工作。RSA就是他們三人姓氏開頭字母拼在一起組成的。其實1973年，在英國政府通訊總部工作的數學家克利福德·柯克斯（英語：）在一個內部文件中就提出了一個相同的演算法，但他的發現被列入機密，一直到1997年才被發表。

- 玻意耳-馬略特定律, which stipulates the reciprocal relation between the pressure and the volume of a gas, was first noted by Richard Towneley and Henry Power. In France, the law is known as Mariotte's law, after 埃德姆·馬略特, who published his results later than Boyle, but crucially added that the relation holds only when temperature is kept constant.
