helical antennas work fine too and look goofy as hell

i’ve used the same (800ml can) and this one works well. cookie tin is 15cm dia 8cm tall and it works, but size can vary a bit. you can copy or scale slightly designs of 13cm band antennas
wait i thought for some reason that pringles can sized waveguide would have cutoff frequency above 2.4ghz. nevermind, there’s something better because bigger aperture can get you more directivity like this https://lea.hamradio.si/~s53mv/wumca/cup.html i made two out of cookie tins and it works over 500m at least
pringles can is too small for 2.4ghz cantenna,it’s near cutoff frequency but just barely, you need 10cm-ish diameter can or shorter 16cm-ish can

nah, what happened is that they were non-psychotic before contact with chatbot and weren’t even usually considered at risk. chatbot trained on entire internet will also ingest all schizo content, the timecubes and dr bronner shampoo labels of the world. learned to respond in the same style, when a human starts talking conspirational nonsense it’ll throw more in while being useless sycophant all the way. some people trust these lying idiot boxes; net result is somebody caught in seamless infobubble containing only one person and increasing amounts of spiritualist, conspirational or whatever the person prefers content. this sounds awfully like qanon made for audience of one, and by now it’s known that the original was able to maul seemingly normal people pretty badly, except this time they can get there almost by an accident, getting hooked into qanon accidentally would be much harder.
this is about exactly what you can expect from a man whose approach to science is take a phenomenon -> think about it really, really hard -> just know how it works and have an answer (without checking if it’s correct or not, he already thinks he figured it out and won’t change opinion ever even in the face of contrary evidence)

iirc L-aminoacids and D-sugars, that is these observed in nature, are very slightly more stable than the opposite because of weak interaction
probably it’s just down to a specific piece of quartz or soot that got lucky and chiral amplification gets you from there
also it’s not physics, or more precisely it’s a very physicy subbranch of chemistry, and it’s done by chemists because physicists suck at doing chemistry for some reason (i’ve seen it firsthand)
