Number systems aren't real math, at least not serious math. They're an affectation. 99.9% of math is number-system-independent, so nobody should care about them. [[Special:Contributions/172.70.46.108|172.70.46.108]] 22:30, 29 September 2023 (UTC)<br />

I thought this was a complete joke, until coming here. The "factorial number system" exists?!

:: It's not a reference to Mario Kart specifically (lots of racing games have ghosts), but that's basically what this is doing - translating the concept of racing ghosts to the real world.--[[Special:Contributions/108.162.216.70|108.162.216.70]] 13:50, 21 September 2015 (UTC)<br />

::: Well, there are some fitness running apps that support a ghost runner mode, so you run against your best time and get updates if you are in front or behind of your „ghost“. Without actually being able to prove it, I believe (and always assumed) this idea is actually inspired from racing games like Mario Kart.

So in the title text, is he being replaced with the ghost who always <i>*ahem*</i> comes last? --[[User:SaturNine|SaturNine]] ([[User talk:SaturNine|talk]]) 12:53, 21 September 2015 (UTC)<br />

I don't know if it's worth mentioning that this appears to be a width-first (route-)search algorithm. A memory-heavy but guaranteed 'perfect' solver of best routing, at every point of choice (from the very first, how you start the journey), all possible/practical travel options are explored (including taking a journey in the 'wrong' direction, or waiting for the non-stop train that is not the first to arrive, to take advantage of connections with faster transport links), in parallel according to the total time (or other measure of efficiency) yet taken on each iteration. Unless any 'ghost' arrives at a node that has already been visited by a 'ghost', when it need not continue. Eventually, the most efficient son-of-a-son-of-a-son...-of-a-son-of-a-ghost will reach the destination, indicating the 'correct' answer. At least within the limits of the split-and-propogate algorithm, and the amount of parallelisation available to devote to the problem. (See also the multiple-overlayed 'searches' performed by two-minutes-of-Nicholas Cage, in the near-climactic scene in {{w|Next_(2007_film)|the film 'Next' (beware spoilers!)}}.)

Will his children have half-siblings that are fathered by the ghost that has replaced him in the bedroom? Or are ghosts infertile?[[Special:Contributions/108.162.215.170|108.162.215.170]] 04:07, 22 September 2015 (UTC)<br />
Doesn't light do this according to some theory, sending out "investigation waves / photons" to determine the quickest way to get anywhere? I'm no expert on this, just some food for thought...<br />
