Friday Fun Thread for July 18, 2025

Be advised: this thread is not for serious in-depth discussion of weighty topics (we have a link for that), this thread is not for anything Culture War related. This thread is for Fun. You got jokes? Share 'em. You got silly questions? Ask 'em.

Also some nominative determinist fun.

This was a really fun paper to read, especially since I just noted that I'm going through an MIT OCW nuclear course right now. My actual knowledge on the topic still rounds to approximately zero, but it was actually enjoyable to just go through the proposed reactions/decays, just pull up the same tables they're using, do the incredibly simple energetics calculations, and see that they are, indeed, correct. I would have had no clue how to do even that just a few months ago.

So, can confirm that the stone simple energetics work; they're not so far out to lunch that they've made such a stupidly basic error (we're not dealing with total cranks). I can't say much of anything on any of the many many other questions involved concerning reactor/process design, materials handling, economics of it, etc. They do point out some prior works that had looked into this in the past, so it's also not unprecedented, but the current authors get an order of magnitude more production in their calculations. The current authors, correctly in my view, point out that the prior works (in the 80s) didn't really show their work for how they got their estimate for gold production, as they were focused on cobalt (and the current authors write reasonably significantly on mercury enrichment, which prior works didn't, and I don't have the knowledge to evaluate). There may be (and probably is?) some other technical barrier to the rest of the scheme that an experienced nuclear engineer would spot in an instant, but if not...

What a time to be alive!

I'm going through an MIT OCW nuclear course right now.

Then you seem like the best person to ask this rather obvious question: why is nobody doing that in conventional fission reactors right now? At least the fast breeders should have suitable neutron flux, right?

just asked myself the same. My wild guess is - it requires some major redesign.

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!
