I used to work at NASA in Virginia. It was nothing glamorous; I was just tasked with making code compile for obscure projects, and I wasn't very good at it. Now I spend most of my time drawing pictures and looking at funny things on the Internet, which in retrospect is largely what I did at my old job, too.

I've always thought that one of the the great thing about physics is that you can add more digits to any number and see what happens and nobody can stop you.

I don't have hard numbers about this, but the impression I get is that the amount of eyeballs you get from being on the humor shelf at Barnes & Noble - it is almost insignificant.

Google owns YouTube, and recently, I drew a comic about an idea for a YouTube feature - which they actually took seriously and implemented. So I'm thinking that maybe we'll have a future where Google is 'xkcd.'

Correlation doesn’t imply causation, but it does waggle its eyebrows suggestively and gesture furtively while mouthing ‘look over there.’

I think the really cool and compelling thing about math and physics is that it opens up entry to all these hypotheticals - or at least, it gives you the language to talk about them. But at the same time, if a scenario is completely disconnected from reality, it's not all that interesting.

It's tempting to just write a comic called 'Everyone Mail Randall Munroe Twenty Bucks' - maybe it would work, and I could just close down the 'xkcd' store and sit on a beach and draw pictures and make snarky Reddit posts for the rest of my life.
