    But they didn’t say “stemmed”. They said “stemming”. But sure, they’re technically correct in a historical context. I wanted to be more precise about the current definition. Under that current definition, it’s actually degree Celsius that stems from Kelvin.

    The original Fahrenheit system was actually pretty clever. It set 0° at the temperature of brine and 96° at internal body temperature. That made marking a thermometer really easy. Like, ridiculously easy. 96 is divisible by two many times before reaching a decimal.

    Because the freezing temperature of water was really close to 32°, the later Fahrenheit system set that as the lower temperature and 212° as the boiling point instead of using body temperature. That made marking a thermometer more difficult, and basically took away Fahrenheit’s only advantage. It was more consistent though. Now Fahrenheit is formally defined based on Kelvin.

    Centigrade was originally marked as 100° at the freezing temperature, going down as temperature increases to 0° at the boiling temperature. Obviously that didn’t last long. The downside is that marking a Celsius thermometer depended on atmospheric pressure. Now Celsius is defined based on Kelvin by -273.15° being absolute zero and a degree corresponding to a very specific amount of heat energy increase.

    So yeah, Fahrenheit hasn’t made any sense for many many years.

    This is so dumb. Of course you can run an app coded by your friend. Either your friend can pay $100 a year to notarize their app, or you can pay $100 a year to run his app as a developer. Couldn’t be easier.

    Edit: apparently I need to add /s. I figured this was a stupid enough take that it was obvious.
