Mostly doing physics, I sometimes also end up forcing together various innocent binaries in /bin and /usr/bin to get a job done. They usually hold together just long enough to finish :\
I don’t answer questions that use non-SI units.

On the derivative of a Heaviside step function being proportional to the Dirac delta function
It should be noted that this works for arbitrary small integration limits $\pm \epsilon$, which excludes most/all functions but $\delta(x)$ from fulfilling the requirement.
