This video is about a new stunning visual resolution of a very pretty and important paradox that I stumbled across while I was preparing the last video on logarithms.
00:00 Intro
00:56 Paradox
03:52 Visual sum = ln(2)
07:58 Pi
11:00 Gelfond’s number
14:22 Pi exactly
17:35 Riemann’s rearrangement theorem
22:40 Thanks!
Riemann rearrangement theorem.
This page features a different way to derive the sums of those nice m positive/n negative term arrangements of the alternating harmonic series by expressing H(n) the sum of the first n harmonic numbers by ln(n) and the Euler–Mascheroni constant. That could also be made into a very nice visual proof along the lines that I follow in this video
Gelfond’s number
e^π being approximate equal to 20 π may not be a complete coincidence after all:
