There is a blowup of the RHS "pixel" which if I read the graphics correctly implies the horizontal axis to reach to well over 10^60 to 10^80 or even 10^100 Bernoulli trials of a particular random walk that was actually performed. Now I'd set 10^10 as a realistic estimate of how many steps per seconds a random walk can be simulated on a single computer, and I can generously expand that to 10^20 factoring in parallel computations. 10^30 is then reached after 10^10 seconds, which is about a third of a millenium, while the current age of the universe only brings us to about 10^38 steps. Therefore the graphics can only be some sort of a synthetic picture of what plotting the result of an actual random walk could look like, and not a picture abstracted from a particular random walk actually computed. IMO this should be mentioned in some way.178.238.175.249 (talk) 09:06, 22 February 2014 (UTC)
