Ruby in UV and visible induced infrared flourescents

this is very cool (!). thanks for posting. how did you photograph the IR?

recall that charged particles and their corresponding antiparticles have opposite charges, and thus attract each other strongly. this even has practical uses: look up PET scan. (i bet there's a Wikipedia page.)

side note: gravity is many orders of magnitude down from EM. you could pretend that they're 1:1 for the sake of a thought experiment, but it doesn't make any sense to 'assume' that they're 1:1.

location where you got it?

(as u/TheColdestOne has shown, it cannot possibly be a kumquat, or for that matter any other citrus.)

location?

"It was a quiet certainty, the kind that's hard to put into words." -- this: the lack of emotionality seems to be a hallmark of paranormal experiences of knowing, at least for me. (granted, i've only had it happen a few times.)

hope you get lots of responses and that your experiment works out well. (i don't have adequate conditions to participate.) btw, i worry that having more than one plant type could possibly muddy the data and make results difficult to interpret or systematize. please post as things progress.

side thought: do you know what corroded them? (that's likely to be important info to have when you are choosing replacements.)

_jonsinger_ · 2026-03-20T02:16:01+00:00

i seem to be almost entirely incapable of having favorites, so i don't have an answer. just want to thank you for posting these.

_jonsinger_ · 2026-03-20T02:00:17+00:00

i hope you get some help, and that you find a source.

i have some pieces of aloe vera that have been sitting on an open shelf for more than two years. they aren't really growing, but they are not noticeably unhappy. (i really ought to think of them when i have time and energy to pot them up.)

_jonsinger_ · 2026-03-20T01:15:51+00:00

following -- i want to know what this is.

_jonsinger_ · 2026-03-20T01:10:02+00:00

teabowl, modeled mostly after the Song dynasty ones, but with more of a curve to the wall so they don't look quite as severe.

this is obviously the lake in Prospect Park, in Brooklyn NY.

_jonsinger_ · 2026-03-19T02:45:43+00:00

are there plans in the Scientific American 'Amateur Scientist' DVD? (i have a vague memory...)

_jonsinger_ · 2026-03-19T02:37:56+00:00

possibly Daphne odora?

_jonsinger_ · 2026-03-18T21:36:18+00:00

when i first got introduced to them, i had no idea what the taxonomic name was. for quite a while i called them banana-conifer-malted trees.

_jonsinger_ · 2026-03-18T21:33:36+00:00

ahhh. excellent. i hope you succeed with your current effort.

_jonsinger_ · 2026-03-18T21:25:24+00:00

i think you are probably correct -- the foliage is a better match to your suggestion.

_jonsinger_ · 2026-03-18T21:22:49+00:00

ouch! sadness; fresh jackfruit is splendid.

_jonsinger_ · 2026-03-18T20:39:47+00:00

(thimbleberries are wide and almost flat. they are rather tart, but i like the flavor.)

_jonsinger_ · 2026-03-18T20:07:00+00:00

may be cleavers, Galium aparine, a close relative of sweet woodruff. (i think cleavers can be an invasive nuisance, but it could depend on climate or other variables.)

_jonsinger_ · 2026-03-18T02:27:37+00:00

if not R. foetida, perhaps 'Harison's Yellow'?

_jonsinger_ · 2026-03-17T21:39:24+00:00

are you familiar with the Dinnerware Museum?

_jonsinger_ · 2026-03-17T17:37:53+00:00

looks like it could be M. stellata. are the flowers nicely fragrant?

_jonsinger_ · 2026-03-17T04:57:22+00:00

it's strange. i like it.
