    David is one of my most favorite guests on Numberphile, Brady. I am so happy to see him on Objectivity. Perhaps a future discussion with Dr. Eisenbud regarding hyperdeterminants and multidimensional matrices is appropriate?

    O... M... G..., David Eisenbud has a VELVET voice, too?! Can we just have a twenty minute episode of David and Keith having a one-on-one conversation about, oh, I don't know, ANYTHING?

    It gives me butterflies to my stomach seeing the actual handwriting of brillant mathematicians and physicists of previous generations. It is kind of sad that next generations won't be able to do the same with scientists of our time, papers being typed today.
    (PS Dr. Eisenbud is such a gentle person, i love to see him in your videos.)

      Many physicists still do alot of algebra in hand, of course it never gets published in that form, but i bet you could still find some stuff like this among physicists. Especially the older guys.

    • @comsubpac

      When were papers ever published in handwritten form?

    • @Liliou
      @Liliou 6 ปีที่แล้ว

      Lasse true I didn't think about that, let's hope some of it gets well conserved so that people can have a look at it in the future and enjoy it

    2021, after rewatching this I looked up Arthur Cayley and discovered he was born in 1821, so it's been his bicentenary this year! No details in Wikipedia about Cayley's family, so no clues, alas, as to who he was mourning in 1869, whether a wife or a child.

    Never ceases to amaze me. Yet another excellent video, that gets several dislikes. Are there people who literally go through as many YT videos as possible, and just Thumbs Down every one they can? Quite what is it that some (ok, only 3 as of now, but the principle stands) people dislike about this video?
    Is it just bad mouse control.."meant to click Like but hit Dislike by accident"? Or just pure malice?
    I despair of humanity sometimes!

    The 23 fundamental thingies wouldn't have anything to do with the number of dimensions string theory started out with right? I remember from numberphile's -1/12 video that 12 has some significance and string theory is down to 11 dimensions now iirc?
