  • Specifically, radio operators like them - with a directional antenna, it matters which direction goes from Canada to Australia the fastest, and if your station is fixed it can even be a paper map.

    I don’t know what sailing yachts would use. Probably a close-up map that’s nearly flat anyway, since surf, wind direction and local obstacles are the main consideration. In commercial or military sailing, it’s entirely possible normal navigation just takes place automatically and digitally at this point. Sextant, compass and Mercator still exist as a backup, though!





  • The Yugoslavia example is very worrying. Who knows how they would have fared in an invasion, but just normal politics was deadly.

    In the modern digital world it doesn’t seem necessary to decentralise much, since lines of communication can be very durable, if not necessarily fast. Even North Korea has data going in and out. If chain of command is clearly established and enforced ahead of time, and forces are numerous, integrated, nicely hidden away and given initial orders, I don’t expect decapitation would work well. Not in the Canadian cultural context.

    I hear the Taliban has been an inspiration in these wargames. That works, they’re definitely hyper-central.











  • I mean, me neither. But if all sets are finite AoC just trivially holds, right? You can do it “manually”.

    If you back off to just ZF, parts of functional analysis will break. Linfinity space isn’t separable, and so isn’t necessarily Baire anymore, for example.

    If we go all the way to finitism or ultrafinitism it doesn’t really exist as a concept in the first place. But, whatever numerical engineering calculation will still work, and you can probably do something that looks like functional analysis to determine a mode of vibration, even if you’re actually just using a series of high-dimensional but finite spaces. Probably, anyway. Don’t ask me to prove it.
