Makes sense in physics, I guess

Haha lol I love polynomial long division for some reason

Matrices. I learned them in algebra 2 and never saw a real application until quantum mechanics getting my physics degree. Linear algebra this and computer science that...it seemed completely skippable

The purpose of the above experiment was only to verify the claim that a mist (by analogy, a cloud) is made of droplets of a particular size. Since they are microscopic, it's tough to have firsthand knowledge of them.

I have a feeling I over-answered you 😅

The smallest dirt particles, clay, sink through water so slowly that the water may be muddy for days. This is because each particle, though more dense than water, doesn't have enough mass to effectively displace water. They understand by analogy that small particles fall slowly, remaining suspended.

Sorry, I wasn't clear... The student's question was actually about whether fog counted as a cloud. I went down the rabbit trail and ended up on this video.

By this point in the curriculum, we would have seen how quickly sand falls through water, but smaller particles like silt sink more slowly.

That's really cool! Reminds me of this album art. Yours is badass

They are kind of stuck, suspended in the oil. I don't see an awful lot of motion unless the oil is moving. That is a good comparison though

I feel the same about math I've done. I liked *doing it* and now that it's done, I have a product I can be proud of. If I just Googled it and skipped to the end it would be joyless, and if I had GPT give it to me I would feel nothing.

Awesome! Are the happy couple Satanists too?

I can recognize students who approach and digest my subject the way I did, versus those who did not...but that's an egocentrist view unworthy of an objective assessment. I love the diversity of people who go through my classes.

And even if they were like "Cool, let me try that" it also can't make them left-handed
