Sticks and stones may break my bones, but words can make me think I deserved it.

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 learned very early on in life that not everyone wants to hear every fact in the world, even if you want to tell them everything you've ever read.

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.

If 'other people have experiences incorrectly' is annoying to you, think how unbearable it must be to have a condescending stranger tell you they hate the way you're experiencing your life at just the moment you've found something you want to remember.

But I’ve never seen the Icarus story as a lesson about the limitations of humans. I see it as a lesson about the limitations of wax as an adhesive.

Take wrong turns. Talk to strangers. Open unmarked doors. And if you see a group of people in a field, go find out what they are doing. Do things without always knowing how they'll turn out.
