This is one of the most insightful things I've read about the field of mathematics in a long time. (And I read it on tumblr!)
Content includes:
Quotes from top mathematicians/physicists explaining how other top mathematicians systematically try to make their work seem more like a work of genius (as opposed to something *you* could do)
Positive argument for mathematical insight being hard yet doable through hard work as opposed to only doable via magic/genius
Then a separate person follows up with arguments that totally surprised my assumptions. I find that the pendulum in math lectures is swung way too far towards 'formalism only, no intuition', but the person (a math tutor) explains how if you swing the pendulum too far the other way and a lecture is all intuition and no messy details, this causes the students also to lose understanding.
I'll add another supporting quote. Mathematician Niels Henrik Abel says of Gauss : "He is like the fox, who effaces his tracks in the sand with his tail."
A counter-example to this sleight-of-hand behavior is Euler. As related by Polya here: https://archive.org/stream/InductionAnd AnalogyIn Mathematics1 #page/n109/mode/2up
(markdown bugs up the underscores in my link)
I think you can get around the messed-up-link problem in at least two ways. First, write some link text, select it and use the make-a-link button like this. Second, use Markdown: link text in square brackets immediately followed by link URL in parens like this. If I've guessed correctly, those should both be links to the Polya thing you were hoping to link to.
[EDITED to add: hmm, first one works (once I fixed a wrong guess at what the URL was meant to be) but second one doesn't function as a link at all, which I suspect may be a Markdown bug. ...... (read more)
