Yeah, but do they like Huey Lewis and the News?

Hey Paulina!

OTOH, if you can afford basic necessities, hobbies are just a rounding error on top of them.

Your numbers seem reasonable — more intuitive for me to work in terms of pressure. Atmosphere is (roughly) 1e3 Torr, good UHV can be around 1e-10, so that’s 13 orders of magnitude, which is (roughly) the same difference that you calculated.

Aluminum foil is very common in physics labs. And a main use for it is “baking”! To get ultra high vacuum (UHV)* you generally need to “bake out” your chamber while you pump down. Foil is used same as with baking food — keep the heat in and evenly distributed on the chamber.

Sadly, it’s usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.

*Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan’s trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That’s roughly UHV pressure.

From TFA:

“I have failed you completely and catastrophically,” Gemini CLI output stated. “My review of the commands confirms my gross incompetence.”

Can go directly upwind (no tacking required). Can also be applied to boats.

Beautiful!

Sorry you’re getting down voted — lots of replies from folks unclear on what the diffraction limit means, atomic resonances, etc.: https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/

Parent didn’t say resolve, they said see — you can’t resolve stars but you can most certainly see them.

Light up a single atom enough and you can see it (unclear if this works with a dark adjusted naked eye or if a long exposure is required): https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/

No, they’re too small to resolve. You can see small things if they’re bright enough: https://www.newscientist.com/article/2161094-a-single-atom-is-visible-to-the-naked-eye-in-this-stunning-photo/

A single atom of gold is far too small for any photon in the visible spectrum to interact with.

That’s incorrect — single atoms can, and do, interact with optical photons.

And the entire field of super resolution microscopy relies on small things (e.g., molecules) interacting with light.

Wait until you hear about the Arctic circle…

No experience with them so can’t at all vouch for them, but it looks like there are providers who will do this.

I self host Immich with an off site backup (=raspberry pi at in-laws house, all over WireGuard). Can’t recommend Immich enough!

The energy from nuclear reactions can be astonishingly large (compared to, say, chemical reactions).

But atoms are really, really, really small.

You’re not just “sticking it to the man” when you do this though — you’re being a dick to your city, its residents, and employees.

Move ‘em 2 millimeters in the wrong direction and you’ll have a bad time

Are you referring to getting, I dunno, yogurt in places outside the digestive tract?

My understanding was that gut bacteria play a pretty crucial (beneficial) role in overall health, not to mention the whole gut-brain stuff.

Pretty sure those “horrible little scalawags” play some pretty crucial roles in the human microbiome…

Or just a San Francisco resident — these ads are everywhere on BART (+Muni I guess) right now. (As far as ads go, they’re pretty good I guess — and no, I don’t even use them, much less work for them.)

ZigBee router thing:

I’ve been happy with the SMLIGHT SLZB-06M. You can easily flash firmware, and it has PoE which was important for me. I believe it also supports Thread, but I haven’t tried this yet (and I’m not sure if it supports it at the same time as Zigbee).

Zigbee smart plugs from Third Reality have been pretty solid in my experience, and they report power usage.

For circuit breaker level monitoring, I have an Emporia Vue2. I have it running esphome, completely local — unfortunately this requires some simple soldering and flashing, so it’s not turnkey. But it’s been rock solid ever since flashing it. (Process is well documented online.)

I’ve had decent luck with cheap wifi Matter bulbs, but provisioning them is finicky, and sometimes they just crap out and need to be power cycled; Zigbee bulbs (e.g., Ikea) have generally been reliable, though sometimes I’ve had difficulty pairing them initially. After power cycling a Matter WiFi bulb, it takes a while for it to respond to Home Assistant; Zigbee bulbs generally respond as soon as you power them on.

I have a wired smart light switch from TP-Link/Kasa (KS205), and it’s been completely hassle free (and totally local — Matter over wifi). The Kasa smart switch dongles I have work flawlessly but need proprietary pairing, and I’m afraid to update firmware in case they lose local support.

Good luck! Fun adventure :)
