HM = Harmonic Mean: Even if it sounds counterintuitive to an untrained eye, this mean appears in the very laws encoded in our universe. For example, if you go from point $A$ to point $B$ with a speed of $v_1$ and come back with a speed of $v_2$, what is your average speed? A bad student would say $v_{\text{avg}}=\frac{v_1+v_2}{2}$, but a good student would know it is actually the harmonic mean: $v_{\text{avg}} = \frac{2}{\frac{1}{v_1} + \frac{1}{v_2}}$.
