    $\begingroup$ I find admirable for a 22-year man to have such math knowledge. I'm 24 and although working hard, I still dream about it... $\endgroup$

    $\begingroup$ If stackexchange had been invented when I was your age I might never have become a vicar ... stunningly good performance. This forum makes maths visibly international, and raises the bar for everyone. Blindingly good performance. Congratulations Qiaochu! 200k beckons ...? $\endgroup$ Commented Nov 9, 2012 at 22:21

Thanks, everyone! I'm happy that people are getting something out of my contributions.


Yes, indeed! Qiaochu, thanks for your contribution to MSE!

Qiaochu's questions are valuable too. I respect his willingness to admit to the world he doesn't know everything. Not everyone is secure enough in their own knowledge and abilities to do that. Count me as a fan. (Forgive me: in my head I read your name as Pikachu.)


Qiaochu's research is really appreciable. The fact that he is only in his 20's and is liable to become a Mathematics professor is unbelievable. I wonder how he did all this in such a short time! I really love his blog.

Best of luck for the future! We guys are with you!

P.S.: 200k is not too far! enter image description here
