Web23 Jun 2009 · If you sum the harmonic series starting from 1, then pretty soon you are adding very small values to something which is O (1). If instead you can start summing from 1/n (where n is some large value) and then add 1/ (n-1), 1/ (n-2), and so on, you will be summing values which are much closer in magnitude.
