Darth Calculus 🏳️🌈 @darthcalculus.bsky.social · 20hScience folks...is there an explanation for this? I usually teach radiometric dating to 8th graders with an experiment where we record the temperature of hot water as it cools over time. The trend is roughly exp decay, but this year I tried to make the curve fit better. Why a fractional exponent? 100

The messengers aren’t people who actually care about STEM. It’s really a shorthand for “do something practical, focus on your relation to the labor market”. 1241379

Darth Calculus 🏳️🌈 @darthcalculus.bsky.social · 22/09/2026I'm giving a practice quiz in algebra 2 today, and it's 3 pages, so I figured I could put the answer key (shrunk to fit on one page) on the back. But with 3 pages, there's still an empty quarter page left. So, I made it appear recursively. Lol #ITeachMath 341
