……一番搜寻之后，他终于找到了原始论文。引理阐述得清晰而简练。至于证明，作者写的是：‘留作读者练习。’而这篇 1941 年论文的作者正是角谷静夫（Kakutani）。”出自 Steven Krantz 的《Mathematical Apocrypha》https://en.wikipedia.org/wiki/Shizuo_Kakutani
…work, he finally found the original paper. The lemma was stated clearly and succinctly. For the proof, the author had written, 'Exercise for the reader.' The author of this 1941 paper was Kakutani." Mathematical Apocrypha Steven Krantz https://en.wikipedia.org/wiki/Shizuo_Kakutani
unless I'm missing something large chunks were taken straight from Mathematical Apocrypha Redux : https://books.google.ca/books?id=8mBdvAjk_gQC&pg=PA155&lpg=P...
The link to Mathematical Apocrypha does something very strange. I think it’s meant to be this: https://www.goodreads.com/book/show/1262199 Edit: now the link works.
这个故事是由 Saunders Mac Lane 讲述的，引用在《Mathematical Apocrypha Redux》一书中：> 冯·诺伊曼在 1927 年引入了希尔伯特空间的公理化描述，并将其应用于量子力学研究中。据说有一次他在 1929 年去哥廷根讲学……
The story is told by Saunders Mac Lane, quoted in the book Mathematical Apocrypha Redux: > J. von Neumann in 1927 introduced the axiomatic description of a Hilbert space, and used it in his work on quantum mechanics. There is a story of the time he came to Göttingen in 1929 to lecture…

除非是我看漏了什么，不然有大段大段的内容根本就是直接从《Mathematical Apocrypha Redux》里抄过来的：https://books.google.ca/books?id=8mBdvAjk_gQC&pg=PA155&lpg=P...

指向《Mathematical Apocrypha》的那个链接表现得非常诡异。我觉得它本意应该是这个：https://www.goodreads.com/book/show/1262199 编辑：现在链接能用了。
