New electrical resistance demos! #Physicsmystery Thanks to @YeanyScience for the inspiration.

Bill Watterson is my favorite cartoonist. I adored the relationship btw Calvin and Hobbes as a child. But as I've gotten older, these strips feel even more tender and insightful. My respect for him grew when I learned of his stance against merchandising. Such principles are almost unheard of today.

NEW: Organ tuners have been leaving temperature and humidity records in little-known books for decades. 🎹 They reveal how temperatures inside churches have changed over time due to climate change and increased heating. A new scoop for The Reengineer! www.thereengineer.pro/p/church-org...

Decorations and wrapping for day 17 of #ChemAdvent! Baubles were traditionally silvered using the reduction of silver nitrate with glucose - a chemical test used in classrooms to detect aldehydes. Wrapping paper and tape are both cellulose-based 🎁 #ChemSky 🧪

Electrifying physics Christmas tree 2025! ⚡ #inductioncoil #neonbulbs #sciencesky

Two years after talking about it, it finally became a reality. The new Archimides density practical for Year 8 was a resounding success. First they needed to determine if the drachma coins were made of gold & then if Hiero's crown was gold or an amalgam of Au & Ag. 👑 #Eureka #density #stories

A bit of a different Christmas tree this year 😉 youtube.com/shorts/BXTsX... #TECHOGNITION #TechniciansmakeitHappen #sciencetechsRULE
