“Here’s a metaphor to help you get a sense for how this complicated thing functions.”

“But it’s not really doing that!”

“That’s why it’s a metaphor, not a description.”

“Here’s an explanation in layman’s terms.”

“No, that’s wrong, that term only means this specific thing when used in the relevant technical jargon.”

“I’m not speaking to people who use the jargon, I’m speaking to the general public, who use the term in a much broader sense than you do.”

And then there’s the flip side:

“I learned this thing was simple. These edge cases can’t possibly exist.”

“You learned the simplified version. The real thing is more complicated.”

As the saying goes, The map is not the territory. The map isn’t complete, but that doesn’t make it wrong either, as long as you don’t insist that the real things that aren’t on your map must not be there.

Tonight, our Star Trek: Deep Space Nine rewatch (on DVD) is up to “Bar Association”, the episode in which Rom leads all of Quark’s employees on a strike to demand better working conditions.

Ferengi workers don’t want to stop the exploitation. We want to find a way to become the exploiters.
Rom, before deciding he’d rather stop the exploitation

A circular halo around the sun, which is behind a tree. A contrail crosses the halo, leaving its shadow on the thin cloud layer below.

A clear 22-degree halo around the sun, bright enough that I didn’t have to adjust the image afterward. This is straight from my phone.

Even cooler: you can actually see the contrail’s shadow on the layer of cloud that’s producing the halo! The sun is behind the tree, and while the contrail pops out so it looks closer than the almost uniform layer, it’s clear from the shadow that the contrail is higher.
