 I removed the comment about logarithmic axes: "The scatter plot uses logarithmic scales.  If they were linear, the origin would be at the bottom left.  With a logarithmic scale you can have fast, slow, safe and dangerous unbounded in all 4 directions."  Having spent lots of time doing plots (logarithmic and otherwise) I'm pretty sure this comment is incorrect.  In fact, logarithmic scales cannot go through zero because log(0) is undefined, meaning that logarithmic plots are the ones that can't be unbound in all four directions.  Also, in linear plots there is no requirement that the origin has to be at the bottom left.[[User:Cmancone|Cmancone]] ([[User talk:Cmancone|talk]]) 17:18, 12 July 2016 (UTC)

 Speaking of it, though, if you DID want to chart fast/safe collisions, visible light photons hitting something would probably rate!

	I think it's worth noting that this chart also shows how unlike a mathematical scatter plot, the position of the points relative to the axes isn't really meaningful. Randall could have chosen to have the entire chart only show the lower right quadrant, and place the other sample points close to the origin, but his choice of presentation emphasizes the discrepancy. Formula 1 car crashes aren't simply "less dangerous" than rocket crashes, compared to rockets they are extremely slow and safe - words that one generally wouldn't use to describe formula 1. 20:28, 5 July 2016 (UTC)		I think it's worth noting that this chart also shows how unlike a mathematical scatter plot, the position of the points relative to the axes isn't really meaningful.

 :None of those events resulted in a crash. All crashes have been fatal as far as I can see.  A crash involves the rocket hitting something.  --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:04, 2 July 2016 (UTC)
 ::By that definition, has there ever been a fatal rocket crash (excluding rockets fired as weapons hitting their target)? Thinking of the US space program: Apollo 1 was a fire in the capsule on the ground, not a crash. Challenger was an explosion in mid air, not a crash. Columbia was a break up on re-entry, not a crash.

 One thing I think it might be interesting to indicate is how this is the first one of these plots where everything is in only two quadrants. There is no slow but dangerous crash nor fast but safe crash. Usually at least one these quadrants would have an entry, and probably a facetious one.
 :True but there has only been three (with this) comic with a four quadrant scatter plot, the other being [[388: Fuck Grapefruit]] and [[1501: Mysteries]]. The other scatter plot are either in one square or not really scatter plots that can be compared to this one. So it may be too slim a data set to say this is special for xkcd. But still interesting enough that there are no fast safe or slow dangerous crashes. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:22, 2 July 2016 (UTC)
 I also think the part about scale could be expanded to more than just the "relative to the speed of light." Something like "While we tend to speak of race cars as going fast, they are slow compared to rockets." --[[User:Trlkly|Trlkly]] ([[User talk:Trlkly|talk]]) 22:27, 1 July 2016 (UTC)
