It's the time between the Winter Solstice and Christmas, and the forthcoming New Year... the perfect time to put a bowling ball (attached to the ceiling by cable) to one's chin, let it go, hold REAL still, and see what happens next.

👨🚀✨ Apparently, orbiting a planet requires more than just a "space license" - who knew? 🚀💨 In this surprise twist, physics nerds reveal that slowing down actually helps you go faster in space 🤯, because apparently, Newton's laws don't apply to #sci-fi movies. Good thing we have WIRED to explain what Star Trek didn't! 📚🔍

Demonstrating Problem Solving: Newton's First Law of Motion
Newton's 1687 preface on Principia Mathematica ✍️
The ancients considered mechanics in a twofold respect; as rational, which proceeds accurately by demonstration, and practical. To practical mechanics all the manual arts belong, from which mechanics took its name. But as artificers do not work with perfect accuracy, it comes to pass that mechanics is so distinguished from geometry, that what is perfectly accurate is called geometrical; what is less so is called mechanical.
Interested in introductory #physics at the #university level? Check out my lecture playlist from when I taught Physics I (PHYS 1303/1307) at Southern Methodist University. The #lectures each focus on a topic and so can be cherry-picked, etc.
I taught using a flipped classroom model, with peer mentoring and active learning during class.
