OTD in 1741, Anders Celsius used a thermometer marked with 100 units between the boiling and freezing points—the first use of what would become the Celsius scale. (He originally assigned 0° to boiling and 100° to freezing, but these would be reversed.) https://t.co/3CjKM74PtY 🌡️ https://t.co/ikRPjqySZf — PolitiTweet.org
