Can Dogs Talk? [PBS NOVA] Questions to accompany PBS NOVA's Can Dogs Talk? This was season 53, episode 3 of NOVA. Do speech buttons really allow dogs to talk to us? Scientists investigate.As of the publication of this resource...

The title pits tried and true attention economy convention against Betteridge’s law of headlines.

I have even more questions. But I’m not here to push your buttons.

There are some interesting findings, but room for skepticism.

Michael Faraday's "your lines of force are highly attractive" is my personal favorite. What's yours?

I always considered it a victory when I was able to transform jaded, "been there; done that" high school juniors and seniors back into the giggling elementary students they had been just a few years ago. Scientist valentines did that reliably.

Here are some ideas on how to implement scientist valentines:

Michael Faraday scientist valentine: Your lines of force are highly attractive.

Valentine's Day has a way of sneaking up on you, #ITeachPhysics colleagues. It arrives a day early in schools this year, but there is still time to prepare.

It’s 50+°F in Bozeman here in February. The Sun’s got some spots, so I thought I’d shoot them before sunset. Neither the skies nor my technique were perfect.

Marco Rubio is no Isaac Newton.

While true, that statement doesn’t pack as much devastation as one might hope for.

I’m no Isaac Newton, and for that I am grateful.

an acceleration graph that increases, then decreases approximately linearly

That's why it's cool! If a force is applied to an object that increases or decreases linearly, you get an acceleration that varies linearly. Every time you takeoff on a plane you experience this as this @phyphox.org graph shows. You do something similar when merging onto a freeway. #ITeachPhysics

YouTube video by Bruce Springsteen Bruce Springsteen - Streets Of Minneapolis (Official Audio)

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Stay free

The one I used was public domain. That probably helps its popularity. Image Playground wasn’t quite up to the task.

In clickbait terms: "Everyone was WRONG about Earth's asteroid bombardment!" But that is not the way.

New NOVA. Season 53 opens with the story of how asteroids might have initiated life on Earth. It's compelling, and evidence for the model is presented.

Nevertheless, I have questions...

My Lessons of Phyz 2025 TPT Yearbook is out. These two are perennial favorite pages.

I scoped out a new shooting location while the auroral numbers looked promising. Forty minutes out of town in a bit of a canyon. Last night’s show stayed low, but I didn’t come away completely empty-handed.

In other news, we are less than one month away from Valentines Day, my #ITeachPhysics friends. Are your Scientist Valentines ready to go?

I never did that for my own students’ letters. One thing I did do was to wish the reader well in attracting my student to their institution / program.

I thought highly of my students and didn’t like the perceived begging aspect of the application process.

Themes/items added The Lessons of Phyz at TPT in 2025. I just finished blog entries for All The Things for 2025. It throws into question my commitment to “retirement”.

With any luck, I’ll do better in 2026.

No spoilers, but keep an eye on that trusty war hero, Benedict Arnold. Saratoga went better than Quebec, and he was put in charge of Philadelphia when the Americans regained it. But everyone’s talking about what happens to him in episode 6.

Hundreds showed up Sunday afternoon in Bozeman, Montana (and in other cities in the Treasure State) to honor Renee Good.

The school’s Van de Graaff generator was there when I arrived in 1986 (it was vintage 1960s), and still working when I left in 2021.

It inspired a favorite demo with a favorite title: Charging Ahead. When we went remote, I created a robust presentation.
