Thing that I learned yesterday (one among many, but this is the most memorable):
The first derivative of distance related to time (change in distance over time) (dx/dt) is velocity.
The second derivative (change in velocity over time) (d2x/dt2) is acceleration.
The third derivative (change in acceleration over time) (d3x/dt3) is jerk.
I knew all of those.
The fourth derivative is jounce.
The fifth, sixth, and seventh derivatives are snap, crackle, and pop.
This makes me very happy.
