Note from Brady: In a previous video I "under explained" the true magnitude of Graham's Number. This is because my brain is small. Apologies to Professor Graham who has a big brain and unsurprisingly explained his number flawlessly. This video is designed as a correction that can also stand alone. It will be our last Graham's Number video (for a little while, at least!)

With thanks to Simon Pampena and Mike Lawler.
