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.
The energy from nuclear reactions can be astonishingly large (compared to, say, chemical reactions).
But atoms are really, really, really small.

Yeah it’s missing the text, “…then the Planck X would be…” for the first two.
And a big plastics shill, unfortunately.
For back-of-the-envelope or mental calculations, pi is often 3 or 10^(1/2).
The latter is better than 1% accurate, and has nice properties when doing order-of-magnitude/log space calculations in base 10.
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 :)
No, I’ve been a strict vegetarian for a long time, mostly vegan now but not strict about it. I did eat fish a few years ago because it was an invasive species (and also, delicious).
But also, I have no problem getting the food/nutrients I need from a plant based diet, which isn’t always easy for other folks.
Thanks for the thoughtful response! 1) makes a lot of sense, and 2) makes a lot of “emotional sense” to me (as opposed to “intellectual sense,” I guess).
“Enters”? You mean they weren’t already in racist meltdown mode?
What’s the conventional wisdom as to why this is so bad, but eating meat basically gets a pass? Like, meat offers sustenance, yes, but it’s by no means required. So basically, humans eat meat because it tastes really good — it’s great “culinary entertainment.”
This is a different kind of entertainment, but it’s deeply offensive to many folks. I’m not trying to be a dick about it, just curious why this is seen as such a sin.
Is it that these animals weren’t “supposed” to be killed? Would a movie about a beef cow who ends up getting slaughtered, both onscreen and IRL, be seen as better? Worse?
Talk to your manager.
Shortly after I was hired, my manager told me I should feel free to decline any meeting that didn’t seem useful, or that if it was preventing me from getting “real” work done.

I think a lot of companies view their free plan as recruiting/advertising — if you use TailScale personally and have a great experience then you’ll bring in business by advocating for it at work.
Of course it could go either way, and I don’t rely on TailScale (it’s my “backup” VPN to my home network)… we’ll see, I guess.
I’m drunk, and it’s all Mexico’s fault!
