Every anti-vaxxer I encounter seems to love weird unregulated supplements. They hate Big Pharma but they love Little Pharma, Big Pharma’s younger sibling who grew up without any adult supervision.

Setting up AP problems in the lab: 2023 Physics 1, KE vs SPE graph The 2023 AP Physics 1 exam posed an unusual question about a cart oscillating on a spring. What would a graph of Kinetic Energy vs. Spring Potential Energy look like, for the cart-spring system? We…

I just set up 2023 AP1 Q1, a graph of KE vs. SPE for an oscillating cart on a spring, in my lab. It's truly wonderful when Physics Works. #iTeachPhysics

They’ll never be *good* at the third law, but this helps an enormous amount! πŸ˜€

Demand that students write descriptions of forces. This method *works*. A person pushes a block to the right. After the person pushes, the block slows down due to friction on a rough track. Draw a free body diagram of the block after the person pushes while the block s…

Here's an example of how my insistence that students list the applying and experiencing object for each force in a free body helped a student get a free body just right. #iTeachPhysics

Watching men's figure skating. Currently in 1st place: Canadian skater Gogolev. Wonder if Gogolev is friends with Disco Stu.

This is about soccer, but has direct resonance for when physics teachers have to do public relations with folks - parents and colleagues and admins - who don’t know about physics teaching but think they do, and yet have a right to give their input. #iTeachPhysics

And shit, there's the first crypto ad. See, the Federal Reserve doesn't need to advertise at all, let alone at the Super Bowl.

Lots of AI baloney. Saw one ad for Draftkings before the game, none during yet. And no crypto so far, thank gawd.

The PSA condemning anti-Semitism loses a touch of its impact when followed by a chorus of toilets singing Phil Collins.

Huh. Super Bowl ad for AI. So, people need to be convinced, at great expense, to use their crappy product. Sorta like pepsi.

Would they say the Super Bowl is in the Chicagoland Area if it were held in Milwaukee? Cause San Jose is pretty far from the GG bridge...

But these are the same folks who think Born in the USA is a super patriotic rah rah America Lee Greenwood-style tune.
