The paradox of the proof

Caroline Chen:

On August 31, 2012, Japanese mathematician Shinichi Mochizuki posted four papers on the Internet.

The titles were inscrutable. The volume was daunting: 512 pages in total. The claim was audacious: he said he had proved the ABC Conjecture, a famed, beguilingly simple number theory problem that had stumped mathematicians for decades.

Then Mochizuki walked away. He did not send his work to the Annals of Mathematics. Nor did he leave a message on any of the online forums frequented by mathematicians around the world. He just posted the papers, and waited.

Two days later, Jordan Ellenberg, a math professor at the University of Wisconsin-Madison, received an email alert from Google Scholar, a service which scans the Internet looking for articles on topics he has specified. On September 2, Google Scholar sent him Mochizuki's papers: You might be interested in this.

"I was like, 'Yes, Google, I am kind of interested in that!'" Ellenberg recalls. "I posted it on Facebook and on my blog, saying, 'By the way, it seems like Mochizuki solved the ABC Conjecture.'"

The Internet exploded. Within days, even the mainstream media had picked up on the story. "World's Most Complex Mathematical Theory Cracked," announced the Telegraph. "Possible Breakthrough in ABC Conjecture," reported the New York Times, more demurely.
