The Calculus of Joy
Make no mistake, dogs know calculus. My own dog can work out all the math involved to determine exactly when and where a projectile will be at an exact point in time, and then be there to meet it. She obviously isn’t doing math, but she is working things out using her emotional intelligence, and she is rarely wrong. I don’t know how she does it, but what I do know though is that she definitely has the formula for joy worked out.
