Speaking of, I just put this together this week to teach vector addition.

Upside: Path of totality went through my driveway. Downside: It was completely cloudy. Upside: Still got great brightness data, and learned a lot about the logness of our perception of brightness and made a simulation to demonstrate. #iTeachPhysics www.desmos.com/calculator/8...

#ITeachPhysics Thank you to @sstoneb.bsky.social for time and thoughtful feedback. I am much happier with this "Capacitor Intuition" @desmos.com simulation now. www.desmos.com/calculator/c...

#ITeachPhysics I've been working on an electrostatics @desmos.com simulation to build up student intuition for parallel plate capacitors including a partial dielectric. I am a little too close to it right now, does this simulation make sense to others? www.desmos.com/calculator/o...
