You know you live in a house full of math and science people when in one day you come across your husband’s pad of scribbled notes that includes lots of calculations and gratuitous use of the word “torque,” your son asks if he can dismantle his roller skates to use the parts to build something that requires wheels and ball bearings, and your daughter casually talks about the reactive properties of common household agents.

I’m excited for the day they use their superpowers together.

Or maybe I should be afraid.
