The Inconsistency of Arithmetic (2011)
Huh, I remember when this happened, but I hadn&#x27;t realized it happened in some blog commemts.<p>For those who are unaware, the comment pointing the flaw in Nelson&#x27;s proof is Terrance Tao, one of the most extraordinary mathematicians in the world. He&#x27;s won a good fraction of the field&#x27;s medals, including the Fields Medal. A nice, down-to-earth guy, too, by all accounts.<p>I jokingly call this the time he literally saved mathematics.
