Shitposter while I tend to two babies. Maybe when I have my life back, I’ll help us get a few more niche communities back?

    Not in defense of the imperial system, but if you’re curious why it’s so arbitrary, it’s a crazy story about untangling a ton of proprietary guild measurements. The mile itself isn’t quite proprietary (it was defined as 8 furlongs, and you can blame the English for ruining a perfectly good roman measurement) but they needed to make it a certain number of chains, rods, yards, and feet, plus a few other obscure measurements I forget about. Naturally that results in a stupid conversation rate (mostly vs yards and feet since it was basically a different system).

    Why we still use it, dunno. I can see an argument for keeping feet and inches for things like carpentry (in the similar way I like hexadecimal in programming) but miles is not that. It’s about as logical as this point as fahrenheit, which is to say it’s outdated nonsense.





  • That’s a pretty valid point, although the rear view usually also blinds me at the same time. Usually I get the full three mirror flash, one from behind and two on the wings, lol. I really like my mirrors, though, they have a lovely convex mini-mirror on them so I get a little extra glance. I still look over my shoulder, but it’s nice to detect someone hovering there before I even make my decision to lane change.

    Teaching stats and using percentages now and again, it’s not really that useful of a tool most of the time since you aren’t usually working with an easy number like 50 (Or 10, 20, 25, etc.).

    Usually what I’m doing is breaking it down into manageable parts (factors), so 6% is 5% + 1% which I can usually do in my head regardless of the number (or if 5% hard, work in increments of 1%, which I can multiply by 6).

    It’s a pretty common strategy to with with factors. Just surprised how many of my students don’t know it!
