Old School Tie

From a review of A Beautiful Mind:

“We are introduced to John Nash, fuddling flat-footed about the Princeton courtyard, uninterested in his classmates’ yammering about their various accolades. One chap has a rather unfortunate sense of style, but rather than tritely insult him, Nash holds a patterned glass to the sun, [director Ron] Howard shows us refracted patterns of light that take shape in a punch bowl, which Nash then displaces onto the neckwear, replying, ‘There must be a formula for how ugly your tie is.’ ”

“Algebra in general is particularly suited for structuring and abstracting. Here, structure is imposed via symmetries and dualities, for instance in terms of Galois connections……. diamonds and boxes are upper and lower adjoints of Galois connections….”

“Perhaps every science must
start with metaphor
and end with algebra;
and perhaps without metaphor
there would never have been
any algebra.”

algebra combined, see

  1. Did you watch Numb3rs, last night? Wait, do you watch Television? If you did and do how accurate is the show. I’m counting on you.
    How’s that for pressure 😉

  2. oh by the way I disagree…algebra would exist because of human’s love for a good mystery.

  3. That’s funny – my husband just sent off an abstract to the A.M.S. – American Musicological Society, that is 🙂
