comment Why is work done $F$ applied over a distance energy?
@user84641 Your comment does not really relate to your question above. Do you know the difference between work and energy?

comment Why is work done $F$ applied over a distance energy?
@Qmechanic I am not sure if the question is "Why is it called kinetic energy?" or "Why is this expression an energy".

comment Estimate the amount of atoms in the smallest speck of matter you can see with the naked eye
1) How did you transform volume to amount of atoms? 2) Why did you pick a sphere, and not just a disk-like volume?

comment Numerically summing a divergent series
Also, I think this question would be much more appropriate on Computational Sciense SE.

comment Numerically summing a divergent series
@grdgfgr The point is that you get an "arbitrary" result based on the amount of terms and resolution. Analytically you might be able to say something useful when taking limit to 0 or $\infty$, but numerically you can only take limits to very small or very large (system precision). This is just not the same thing.
