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.
