    I'm at a conference this week and I mention Yoneda's lemma in my talk. Does anyone know how to pronounce Yoneda properly?

    Is it:


    or something else entirely? (I'd like to at least sound semi-knowledgeable even if I'm really not.)

    at 00:20 you'll hear it (it's an interview to the japanese gymnast Isao Yoneda)

    If you're going to point to YouTube, point to Catsters! :)

    The catsters aren't native japanese people, so there's no reason to think that they will say it correctly.

    I don't think Ian was worried about pronouncing it like native Japanese, but more worried about sounding silly at a math conference :)

    If you'd like to sound like an American cowboy (or maybe Australian outback?), try "Ya-neh-da" :)

    The correct pronunciation is closer to "Yo-nay-da" (as I'm sure they pronounce it in Catsters, although I'm behind a wall where YouTube is blocked at the moment).

    A cute kid's song I learned to practice the sounds...

    "Ko buta... tanuki... kitsune... neko... (repeat ad nauseum)".

    Literally, it means "Little pig... raccoon.. fox... cat... (repeat ad nauseum)", but I think it sounds better in Japanese :)

    The "ne" sound is like "nay".

    I feel I must protest that American cowboys and Australian jackeroos/jillaroos (the parallel occupation from whom one would expect an 'outback' accent) have very dissimilar accents :) (says me from Adelaide, where people from other states sometimes mis-identify us as being from the UK!)

    More seriously, mention of the Yoneda lemma at the American Physical Society annual meeting sounds like score one for category theory. Good on you, Ian.

    Well, in my hurry to get all the words out (since talks at APS meetings are a whopping 10 minutes long), I think I spit out something that roughly sounded like Yo-nay-da. But at least the physicists now know about it. If I figure out someplace to store it, I'll put the talk up somewhere online and link to it from my info page here on nLab.

    And I should report that the presentation went quite well. After the session I was cornered by several physicists wanting more information on category theory. Note that I included a URL for nLab in my talk (which greatly benefited from the input of David and Urs). So we may get an additional contributor or two. Either way, I have some new areas in quantum mechanics and quantum field theory that could benefit from a categorical approach.

    As for accents, with apologies to the English since it's their language, my accent, like many folks from the Great Lakes and West Coast areas of North America, is about as close to dictionary English as one can get.

    Cool. I really wish I could have seen it. Did you know, if the file is not TOO big, you can upload it to the nLab directly?

    Aha! I did not know that. Well, I guessed it was possible, but I guessed one needed a private lab space to do it and I don't have a private lab space on nLab.
