07:51 < hprmbridge> kanzure> "The biggest objection to bringing in the epistemic dimension is that it might to tend to justify rule by the knowers (epistocracy)" what's wrong with that?
07:52 < hprmbridge> kanzure> "There is, however, the nagging thought that even if the knowers aen’t generally acceptable, they do exist. And they might simply be amore accurate source of knowledge about what should be done than any democratic procedure could ever be. I don’t want to deny this." but you will anyway, won't you.

09:33 < hprmbridge> nmz787> Concept and demonstration of a low-cost compact electron microscope enabled by a photothermionic carbon nanotube cathode
09:34 < hprmbridge> nmz787> """To broaden access, we demonstrate an SEM using simple, low-cost, off-the-shelf components, and hobby-level electromechanics; this has been enabled by a thermionic electron source based on a carbon nanotube array excited by low optical power. The instrument offers sub-micrometer resolution, a depth of field of the order of a hundred micrometers, and an image quality comparable to commercial
09:34 < hprmbridge> nmz787> SEMs; it also tolerates poor vacuum and moist specimens, making it broadly applicable"""
09:34 < hprmbridge> nmz787>
09:34 < hprmbridge> nmz787> I will note the comparison to commercial SEMs is comparing to the worst ones.

09:41 < L29Ah> MuaddibLLM: how much does a 0.01 Torr-capable vacuum pump cost nowadays?
09:41 < MuaddibLLM> Short answer: a basic 2‑stage rotary vane that reliably hits ~0.01 Torr (10 mTorr) is ~$300–900 used (e.g., Edwards RV8, Welch 1402) or ~$900–2,000 new; oil‑free scrolls that do the same are ~$1,500–3,000 used or ~$3–6k new (Edwards nXDS, Pfeiffer ACP) - budget a few hundred more for KF‑25 hardware, trap, and a gauge, and remember your chamber/lines will be the real limit if they leak or outgas.
09:43 < L29Ah> MuaddibLLM: how about a 0.1 mTorr-capable vacuum pump?
09:43 < MuaddibLLM> L29Ah: 0.1 mTorr (1e-4 Torr) is high vacuum - think a turbomolecular + controller + backing pump at ~$3k–10k used ($10k–30k new), or a diffusion pump + water cooling + baffle with a rotary vane for ~$1k–3k used but oil-messy; budget another ~$500–1.5k for gauges (Pirani plus cold- or hot-cathode) and note cleanliness, seals, and bakeout will gate you more than the pump spec.
09:45 < L29Ah> MuaddibLLM: can one flush the chamber with oxygen, reduce it to 1 Torr and then seal burn off oxygen with a hot wire to achieve 0.1 mTorr?
09:45 < MuaddibLLM> **Response: Nope.**; ; Flushing with **oxygen at ~1 Torr** and then "sealing and burning it off" with a hot wire won't reliably reach **0.1 mTorr** for three key reasons:; ; 1. **Oxygen combustion doesn’t remove it all.**  ;    *Burning O₂ (hot wire oxidation of surfaces/vapors) only works if you have something reactive (e.g., reducing agents) and even then leaves ppm-level residues, not mTorr vacua.*; ; 2. 
09:45 < MuaddibLLM> **Sealed-chamber outgassing dominates.**  ;    *Residual O₂, water, and surfaces rapidly desorb far beyond 0.1 mTorr within minutes.... (full response: https://pasky.or.cz/muaddib/2b91176793574d5880abf86947ffb1a9.txt)
