Yesterday, everyone was all atwitter over a new preprint by Xian-Jin Li containing a purported proof the Riemann Hypothesis. The optics of it looked good (Li is clearly not a crank), but Terry Tao has identified an apparent error.
More at Not Even Wrong.
[...] It appears that someone has found a flaw in Xian-Jin Li’s proposed proof of the Riemann hypothesis according to the Not Even Wrong blog. (Hat tip: Ars Mathematica) [...]

I think that the preprint of Prof. Xian-Jin Li will be very useful for a future and definitive proof of the Riemann hypothesis. Furthermore, many mathematics contents of this paper can be applied for further progress in varios sectors of theoretical physics.
