Once I got married, I started working from an office. I found that having somewhere to go that isn't my house is mentally helpful: 'This is the place where I answer email and write blog posts,' and 'over there is the place where I do the dishes.

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.'

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.

Sometimes I mistake this for a universe that cares.

The role of gender in society is the most complicated thing I’ve ever spent a lot of time learning about, and I’ve spent a lot of time learning about quantum mechanics.

I think the comic that's gotten me the most feedback is actually the one about the stoplights. Noticing when the stoplights are in sync, or calculating the length of your strides between floor tiles - normal people notice that kind of stuff, but a certain kind of person will do some calculations.

The scholarly authorities on freezing to death seem to be, unsurprisingly, Canadians.
