  • Well yeah, every map projection has to mis-represent something. In this case they’re arguing that presenting area is more important than presenting angles. Outside of long-distance travel on ships and planes, which are not using general-purpose world maps, nobody is navigating with a world map, so I think that they’re probably right here. It seems more important to me to understand the relative size of Africa to other landmasses than it is to know that the Korean peninsula is actually a few degrees off of being straight north of Borneo

    The actual paper the number comes from (Fate of Empires by John Glubb) is complete bullshit, though. Even the cherry-picked examples it uses, which are limited strictly to the surroundings of the Mediterranean, don’t use any kind of consistent criteria for when an empire starts or ends. He tries to count “Alexander (and his successors)” as one coherent entity and then picks an end year in which all of them had either already collapsed long ago or would not do so for many decades to come. He cuts centuries off of the Roman Empire’s lifespan by just saying that the empire was unstable and getting invaded a lot (and ignoring the Eastern Empire entirely). HIs reckoning of the “Arab Empire” includes three separate caliphates, and the end date isn’t even the actual end of any of them

    Other than that, no, it does not attempt to find an average in the sense of a mean lifespan. It actually does argue that 250 years for an empire can be compared to a human living 70 years.
