Small-Scale Question Sunday for June 18, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I've probably watched too many episodes of "Voyage to the Bottom of the Sea" where getting to crush depth is something you don't want to happen, and that high-tech super-sub was not made out of carbon fibre composites.

God rest the dead, but this all does seem like an avoidable tragedy.

"Crush depth" is pretty much defined as "the depth where it's something you don't want to happen". "Design depth", still well below "operating depth", is where you planned for crush depth to be, and most of the time it's not quite as deep, because surely you built your design with tolerances all on the safe side rather than the quick+cheap side ... but based on everything reported up to and including the debris discovery, that doesn't seem to have been the case this time. RIP. At least they went instantly.

Yeah, my jaw dropped when I went to the website and it was cheerily "our prototype predecessor model went to 500m. This time we're heading for 4,000m."

I mean that is some scaling-up without intermediate steps in between! But God rest them all, they paid the price. Including the CEO, so it's whoever is left behind in the firm is going to be carrying the can for this one.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
