Every time you press the brake pedal to come to a stop at a planned location, you’re doing calculus.

It’s easy to lose sight of the idea that calculus is the most natural thing in the world to us. The specific mathematical language used to describe it can be complex, but we continually and intuitively make those calculations with our own bodies.

Me: Use the open sriracha before you open a new bottle.

Kid: OK! opens the new bottle

Me: Why did you open that?

Kid: I couldn’t find the other one.

This is literally where I found the old bottle when I opened the refrigerator.

An open refrigerator with a half-empty bottle of sriracha on the very front of the middle shelf, label facing forward saying “SRIRACHA”.&10;&10;There is another open bottle of it in the background. It is not the 3rd one that the kid just now opened.
