I am bummed that this is not the article the OP is looking for, because I LOVE this! I have a math girl who is 19 and filling out Ph.D. applications as we speak; she has co-authored a half-dozen or so papers and has two more, plus a book chapter, in the works. In other words, she is a rock star in her math world, and she did so much of what is mentioned in this article, especially radically accelerating her math education. The description of the guy who trolls middle schools looking for the next math rock star was pretty awesome. I am going to write him to suggest he also start trolling gymnastics gyms; my daughter says gymnastics desensitized her to failure and that that has been an invaluable asset.
Anyway, carry on, but thanks, Aras, for the link.
