Four people, including an off-duty New York City police officer, were killed Monday evening when a man with a rifle walked into a Manhattan high-rise corporate building and opened fire.

Rulers for scale.

I consider DEI detrimental when people with less skill and knowledge are promoted above those with more. That is the maga argument. The Harvard case of discriminating against Asians is an example.

I've always used CA vs Ca to teach the correct way to write element symbols but hadn't realized how many others there were! And they missed NH/Nh!

The Dangers of Feelgoodism in Education - The Effortful Educator Just because a catchy educational quote or image makes us feel good (or confirms our already established beliefs) doesn't mean it is based in fact or logic.

Excellent (as always) from @blakeharvard.bsky.social

I did think the feelgoodism tweets and memes were innocuous but no... they can engender practices that are detrimental...

Check out this recording of the seismic waves from the M4.1 earthquake in Tenn! This was recorded by a seismometer 180 km away. To see how the ground moved near you visit www.iris.edu/app/station_...

He clearly hasn’t.

It’s a protest against tyranny.

You can go into the settings and remap the keys (what I do) so I have a key that does Caps Lock or you can use

Age is, of course, a fever chill
that every physicist must fear.
He’s better dead than living still
when once he’s past his thirtieth year.

Did you know:
📈 Physicists actually hit peak performance at 50.
🧪 Chemists at 46
💰 Entrepreneurs crush it until 45

Perhaps not as useful...

Not as specific as yours...

Two small circular stamps shown: "Consistent with earlier incorrect work and/or answers" in red and "Awesome physics thinking shown here" in purple.

I made my own grading stamps, they might be a little small though!
"Consistent with earlier incorrect work and/or answers"
"Awesome physics thinking shown here"

When one of them notices your pet peeve and makes it into a meme in physics meme homework...

Though not just a peeve. It is better to say forces come in pairs. The other way implies it's sequential not concurrent.

A student hanging from a “human free-body diagram” apparatus while the teacher points to the tension reading on a scale.

Human Free-Body Diagram apparatus: students can become the “dot” in the middle of a free-body diagram, seeing and feeling the effects of tension, the normal force and the gravitational force. #ITeachPhysics

Where did you find such a heavy duty circular scale?

I'm not drinking tonight. So there.

I've made them with a bunch of scaffolding and solutions as I've noticed that I haven't had enough practice and support for this skill in AP1.

Cgs unit?

I think ratpower is a cgs unit...
