me telling my grandkids what it was like to have vaccines

New blog post!! I wanted to share the mini lab set up that I used to introduce mathematical models in my physics classes. I'm especially proud of the inverse square relationship comparing the diameter and length of a playdough snake 😊 #iteachphysics passionatelycurioussci.weebly.com/blog/pattern...

Last night’s star party at the Great Basin National Park Astronomy Festival was amazing. Clear skies, inky black darkness, large enthusiastic crowd, and well prepared amateur astronomers combined for a memorable experience. I am exhausted, will post more tomorrow.

Hey DOJ, today would be a great day to honor Charlie Kirk by releasing the Epstein Files. KIRK: "The DOJ should immediately move to unseal all the Epstein documents in the SDNY. I think every file should be released to the public."

Genius

NOVA is back. The BBC’s five-part series, Human premiered on Wednesday. #ITeachBiology might work this series into their courses. Part 1 is Origins. paleoanthropologist Ella Al-Shamahi has answers. And I have questions. Human - 1. Origins www.teacherspayteachers.com/Product/Huma...

Luckily, Sinclair has a helpful database of all their stations, so you can see if they're operating in your area and respond accordingly. sbgi.net/tv-stations/

Driving tomorrow to the Great Basin National Park Astronomy Festival to show the night sky to the public. Unfortunately, clouds are heading there too. Saturday looks good, might be partial clearing Thursday and Friday. Fortunately, there are many other events scheduled. www.nps.gov/grba/planyou...

Stunning! Our 2D views are like comparing a live insect to one smashed on the windshield.

First time teaching this class, and I don't think I came up with this idea (some fuzzy twitter #iTeachPhysics memory), but planning to have them guess the power rule first.

Wow! Best viewed on a large screen

Oh this is very cool #MathNerds

If you’ve ever wondered what the aurora “really” looks like, check out this blog article I wrote that dives headfirst into the question: theauroraguy.com/blogs/blog/w... . The bottom line is there’s a lot of nuance to how people perceive the aurora with their bare eyes.

Oop.

The Lake Clementine dam is an hour hike from the top of the Foresthill Bridge. The mist from the water flowing over it created a rainbow and a noticeable drop on in temperature.

"A Dead Statesman" I could not dig; I dared not rob: Therefore I lied to please the mob. Now all my lies are proved untrue And I must face the men I slew. What tale shall serve me here among Mine angry and defrauded young? —Rudyard Kipling, from "Epitaphs of the War", in _The Years Between_ (1919)

#teach180 blog post about the "salami problem" I do in AP C about equilibrium & forces. It's built up as a big memorable demo. I have done this same type of problem, based on a Hewitt Drew-it, in our college prep Physics as well, sans salami. 🎢🧪 breebarnettdreyfuss.blogspot.com/2025/09/sala...

Day 1 cont: 12 Ss started with @cossettej.bsky.social's passionatelycurioussci.weebly.com/blog/game-of.... This is a great way to kick-start the 12s and we talked about the challenges of figuring out the rules of the game from within the game #teach180 🎢

Silicon Valley folks, we will have Physics Show performances for the next two weekends. Tell your friends that they can get seats at www.thephysicsshow.com. Proceeds go towards bringing kids from Title 1 schools to our campus for fun science learning!
