  • Here’s wiktionary:

    Although sometimes used, normalcy is less common than normality in American English. It is very rarely used in the UK, Canada, Australia, and New Zealand. It is frequent in India and Zimbabwe however.

    So it’s a regional thing.

    Although the claim that in US English the “normality” form is more common does not match my experience as a speaker of US English.





  • Do people not remember back in the 2010s when bit.ly was the main link shortener used everywhere on the internet, and then Ghadafi, the then dictator of Libya, declared the site to be incompatible with Muslin decency norms because it was used for porn? And then all bit.ly links were just dead links?

    How many times do we have to learn this lesson? Domain name hacks are fun but just not worth it. And in 2023, now we have all the new TLDs. This was a dumb decision

    the speed of light expressed in units of distance per time, is a dimensionful quantity so it probably doesn’t mean anything to say some theory does or does not predict a value for it. The value is entirely determined by how big you choose your yardsticks and sundials to be, which is arbitrary convention.

    It is only meaningful to talk about theoretical predictions of the values of constants if they are dimensionless, like the fine structure constant.

    However relativity does suggest as a natural point of view that space and time are just orthogonal directions in a unified spacetime. In this point of view, relativity gives you the option of measuring your timelike and spacelike coordinates with the same yardstick (which you may still choose arbitrarily). And then relativity does predict its value. It’s 1. No units.





  • The point wasn’t that ranged attacks or siege or cavalry weapons are more important than melee weapons, though depending on the battle or the century, that may well be true.

    The point was that when it comes to melee, the weapons used by your infantry was never swords. Swords are prestige weapons, expensive and heavy, wielded by wealthy knights and nobility for ceremonial purposes, duels, or tournaments. The king cannot afford to equip a thousand infantry with swords (the way you see in movies like Braveheart or LotR), and even if he could, the infantrymen have neither the skill nor strength to wield them for an extended duration.

    Swords weren’t the weapon of last resort. They just weren’t included in the loadout at all, of the soldiers engaging in melee combat. So what did they use? Spears. That’s probably why the OP says spears are king.

    But take it with a grain of salt cause I don’t actually know anything about medieval warfare. It’s just a thing I heard.
