Don't be a $\frac{d^3x}{dt^3}$

What does it all mean?

    $\begingroup$ So that's a shirt that specifically asks mathematicians and physicists to not be jerks? Because...? $\endgroup$

    $\begingroup$ This question is not that bad, it is about the physical meaning of the time derivate of the acceleration and therefore a legitimate physics question. So it need not to be closed or something as certain people claim ... $\endgroup$

    $\begingroup$ At first, I thought, "Don't be a jolt", what does that mean? Then, I remembered that in some countries, it is called "jerk". $\endgroup$ Commented Jun 22, 2013 at 5:32

It means don't be a jerk. The third derivative of position (i.e. the change in acceleration) is called "jerk", though it's a little used quantity. It's called jerk because a changing acceleration is felt as a "jerk" in that direction.

In physics, sometimes the third derivative of position with respect to time is called jerk.

Jerk is the third derivative, fourth derivative is jump.
