Feb 7, 2011 at 5:57 comment added mephisto The details in the question appear garbled to me. However, I was present when Katz asked Milnor about the story that he had once asked a question at a thesis defense which had sunk the thesis. Milnor looked embarrassed, and said that it had happened. He added that he hadn't been trying to trip up the student --- he had asked the question simply out of curiosity.

Jan 25, 2011 at 18:25 comment added Sean Tilson @ Mariano: I gather that what is meant is that the space is just a finite set of points with the discrete or indiscrete topology.

Jan 25, 2011 at 2:25 comment added Michael Hardy For some decades after the alleged event, a story persistently circulated that a certain professor at a certain institution had fallen out of a window while lecturing. I would tell you some specific reasons why this might have somewhat plausible, but then too many people might guess who it was.

Jan 24, 2011 at 23:18 comment added Gerry Myerson Mathematical urban legends have been collected by Steven Krantz in the book, Mathematical Apochrypha (and I think there's a second volume). A few refer to the thesis defense.

Jan 24, 2011 at 22:44 comment added Dick Palais Willie Wong asked:"@Dick: is that the one Qiaochu recorded below?", and it no doubt is. Perhaps I will add more detail. I first heard it when I was grad student myself at Harvard (so if you know when I got my degree you will realize how old a legend this is !). Moreover the story as I heard it was that the thesis advisor was Garett Birkhoff.
Jan 24, 2011 at 22:37 comment added Willie Wong @Dick: is that the one Qiaochu recorded below?
Jan 24, 2011 at 22:31 comment added Dick Palais Well, and of course there is the old chestnut of the (supposedly Harvard) student who wrote a thesis about the class of functions satisfying a Lipschitz condition of order (1 + \epsilon ) :-) But getting back to the original question, why not just ask Milnor?
Jan 24, 2011 at 22:29 comment added Valerio Talamanca I also had heard an urban legend about Milnor sitting in on a dissertation defense (long ago when I was a graduate student a Brandeis). In the version I had heard the class of new topological space that were studied was observed by Milnor to consist only of the empty set.

Jan 24, 2011 at 22:18 comment added Willie Wong Maybe I hung around the wrong crowd, but I've never heard Igor's story. True or not, it'd be a shame if that story somehow got lost before my generation.

Jan 24, 2011 at 21:21 comment added Todd Trimble I had heard an urban legend about Milnor sitting in on a dissertation defense, but in this story the speaker airily discussed a certain natural transformation, that Milnor expressed doubted it was natural, and that Milnor was right. According to the story, the thesis was completely invalidated because the student hadn't checked naturality, and had to start all over (or something like that).

Jan 24, 2011 at 21:04 comment added Nick Salter Perhaps not an urban legend per se, but when I was learning algebra, my professor, in an attempt to impress upon us the necessity of checking that certain maps are well-defined, told us the story of a classmate of his who got several years into his Ph.D. thesis before realizing that the maps he was investigating weren't well defined. Horrified, we asked him if this was true. "No" he said, "but that's one lie you'll never forget!"
Jan 24, 2011 at 21:01 comment added Bill Thurston I heard a version of this too, from sources I thought were reputable (but I forget who, probably more than one.)
Jan 24, 2011 at 20:54 comment added Mariano Suárez-Álvarez Since every finite CW complex is weakly homotopically equivalent to a finite topological space, that does not sound so bad... :)
