My Erdös number: 3

Don Knuth and Me

Back in 1999, I spotted a typo while reading Knuth’s Digital Typography. I sent him an email pointing out the error (it was a very minor one), and forgot about it. Within six months, I received a letter from him with a brief handwritten note — and a cheque for $2.56. This is one of my most prized possessions.


My one success at nonacademic publishing

In the fall of 2011, I emailed a cartoon idea to Dan Piraro, who writes the Bizarro comic strip. Much to my surprise, he liked it and decided to use it! Since I initially wanted to be a cartoonist when I was young (back before I wanted to be a mathematician or a philosopher), this made me happy. I like the socioeconomic commentary of it.
