Chemistry and biology are interchangeably blue or green, physics is yellow, comp sci is red.

Cryoprotectants also do this pretty efficiently – they prevent crystallization, which leads to “vitreous” ice, which has more or less the same structure as liquid water and so doesn’t expand much. I think they do use that when freezing people, but the problem is that even if you fill the blood vessels with pure ethylene glycol, it diffuses very slowly, and it takes hours to get into cells which are far from large blood vessels. They dont diffuse the cryoprotectant in that thoroughly, though, because that’d take so long the body would have started to decay too much.

I just mean that its pretty hard to do research with no money at all, and any funding should be reported in that section.

Oh that would be so fun but my brain can’t math that…

Doing a study like this with no funding whatsoever is…suspect at best

You also can’t mention it to the Dutch, they’ll get way too excited.

The thing about green photons having too much energy isn’t really true, though it’s commonly talked about. Blue photons are significantly higher-energy than green, and are very well-absorbed. There’s speculation that our sun (being a greenish star) just produces too many green photons, and absorbing so many so fast would be detrimental, but I haven’t seen that definitively proven yet. People are trying, though – there are all sorts of papers about making artificial supplementary antennae to absorb in the green region.
There are a couple proposed reasons to reflect green, which range from information theory arguments about decoupling different parts of the photosynthetic mechanism, to the ‘purple earth’ hypothesis mentioned in another comment, to the ‘green sun’ idea. My point is, the why of green photosynthesis is not a settled matter.
Also, the absorbance of red and blue photons isn’t because red and blue photons have useful energies, specifically. The photons excite electrons in a ‘high energy’ path and a ‘low energy’ path, yes, but the elections excited by these photons don’t directly do chemical work – these exitons are in a quantum-coupled system which is very complicated to understand (I won’t even pretend I understand it fully), and the reduction potentials further down the line are only indirectly (and not proportionally) connected to the energies of the original photons.
Basically, we have studied photosynthesis really intensively for like 50+ years, and in some ways it’s still basically magic. The more we study it, the more information we have, but more often than not that leaves us more confused, because it’s just a crazy system. And I, for one, think that’s pretty damn cool.
Will edit later with sources.

Open board is unmaintained, heliboard is the fork, and has added some great features IMO.

Laziness. That figures.

That is generous on what you can lick…
About half of the green ones would still probably kill you, just…slowly.

Ahhhh it’s a humpy, I stand corrected. Not familiar with them. That’s absolutely wild!

Photoshopped, unfortunately. They change, but not that much.
- Comment on speedometers 3 weeks ago:
Hmmm, he says, reveling in his pedantry: Speedometers actually measure net displacement, and since thermal energy causes collisions on the small scale, but results in very little net movement for the particles, its not quite like a speedometer.
I like to think of it as a ball pit with one of those super bounce ball stacks in it.

I’ve tried multiple times to get the song ID to work, but the birdsong has to be so loud in the recording for it to detect it that I rarely get close enough to a bird for it to work. I was sad about that, it seemed so cool. And to be honest, for visual ID, I still prefer a bird book. Maybe it’s just a me thing.

Do you really think you could build a tower without tensile reinforcement? The hoop stress on the base of a cylindrical tower is no joke, especially when made from something as dense as concrete…
- Comment on Kobo's new color E Ink eReaders start at only $150 4 weeks ago:
No, I forget where exactly it was, but at some point last year I was deep in Rakuten’s documentation and it referenced that the Clara HD’s OS is based on a modified Android 8 kernel.
- Comment on NASA 4 weeks ago:
Well, yeah. The earth is a better reference frame, but the orbital velocity of the moon (3679.2 km/h) is no less impressive.
- Comment on Kobo's new color E Ink eReaders start at only $150 5 weeks ago:
That’s true, but I get easily more than that on my current kobo, which has a similar advertised battery life. I can get easily 5-6 days of reading 8h a day on it.
- Comment on Kobo's new color E Ink eReaders start at only $150 5 weeks ago:
All kobos use a custom OS built on Android…8 (lol). Its not recognizable as Android, but it is the base.
- Comment on 3 days 🤯 1 month ago:
Oh it should be roughly equivalent. But really, what besides a slab can you build without worrying about tension?
- Comment on 3 days 🤯 1 month ago:
I can only assume they’re trying to talk about concrete 3D printing, but oh boy is that not ready for anything which needs strength.
- Comment on shoot for the moon 1 month ago:
Yeah, it’s a funny meme, but a basic understanding of physics reaaaallly flips it on its’ head.

This is my exact situation! It’s not just uncomfortably small, either – it’s flat out unusable. I think its a hiDPI issue, but from the forum posts it sounds like its been an issue for 5-6 years. I even tried changing the QT startup settings, but no luck.
