Hypersonic heating is really weird. We only have data going to about mach 17 (the HTV-2 was the fastest solidly atmospheric vehicle I found) but as we go from subsonic, to supersonic, to hypersonic regimes air becomes pretty much incompressible, and forms a really solid shockwave in front of a fast-moving object. Air is a pretty good thermal insulator, so for very fast, blunt objects they actually heat much slower than you might expect.
Tl;Dr it absolutely vaporized, but it likely lasted longer than you might expect.
- Comment on Heavy Metals 2 weeks ago:
Doesnt exist. Some metals can form organometallic complexes (with CO, CN, methyl groups), in which case you get for instance “organic mercury” compounds. Iron can also do that, but that’s not what theyre talking about here.
What they mean is “biogenic” iron. The snail precipitates dissolved iron and sulfur in the water to form its shell out of iron sulfide. Its a different physical structure, but chemically similar to iron pyrite (fools gold).

There are two “halves” but they’re nowhere near symmetric. The two parts nested inside one another in (a) are the “halves”.
- Comment on Makes more sense than the Imperial system 2 weeks ago:
The SI base unit is actually the kilogram (despite naming), a metric tonne is actually a megagram lol.
Anyhow, if the prefix-less naming matched the base unit, 10 kg would be a “decagram”. As it is, it’s 10,000× the base of the naming system, and theres no prefix on factors of 10 above 1000, so sadly there’s no way to name it neatly.
Edit: actually it looks the like the Greek for 10,000 is “myriad”, so it would be a myrigram. Dope!
- Comment on YEET 2 weeks ago:
One thing that no one ever talks about with this is the massive air resistance on it going Mach 164 through the atmosphere would incur (albiet for a very brief period)…I bet that would knock 25-50 kmph off it easily.

Second…trilogy? Do you mean the hobbit movies?

Could it have been the movie version of Eon by Greg Bear? Haven’t seen the movie, but sounds very similar to the book.
Side note: it took me like 6 years and a lot more reading before ran into Rendezvous with Rama by Arthur C. Clarke and realized that Eon was…heavily inspired by thay book.

You’re allowed to like gimmicks!
What makes them a gimmick IMO is that they’re sold as “this will change your life and the way you work”, but really it’s just that a subset of the audience for the gimmickless product thinks they’re kinda neat.

It is how it’s generally taught in schools, which is unfortunate.

Nope. RNA is chemically different: different sugar in the backbone, and there are wayyyy more than 4 RNA bases (like 12 iirc)
- Comment on Call me 5 weeks ago:
Something called a “lesion” around a base mismatch, basically a bubble in the strand pairing. It can introduce kinks in the helix, and generally is the result of mutation in one strand.

I mean honestly? If you’re not even keeping full cells from the prey, I think we can give it to them. Lil guy, you can photosynthesize. No need to bother them with the asterisks.

That is true, but part of improving our environmental impact will be decreasing that transport of raw materials, localizing chemical industries near the sources of their raw materials.

Sure the threat model is different, I’m just saying it’s still a single point of failure.
- Comment on "EU-Linux:" Petition calls for the implementation of an EU-Linux operating system in public administrations across all EU countries 1 month ago:
I mean yes, but currently they’re all dependent on Windows, so its less of centralizing OSes, and more changing what its centralized on.
- Comment on It hurts me. 1 month ago:
Yep! The LD50 is 12.5% in air (higher than I thought, honestly) and yes the issue is that it binds preferentially to hemoglobin.
The main treatment for sub-lethal exposure is just supplying pure oxygen to kick the equilibrium the other way and slowly remove the CO from your system. It won’t all come off, but your body recycles red blood cells pretty quickly, so you’re back on your feet within a few hours and back to normal within a few days. However, there’s no treatment for lethal doses, people have proposed using things like cobalt porphyrins (which bind CO even better than iron hemes) to more quickly sequester the CO from your hemoglobin, but that’s not been trialled yet in humans.
I wasnt aware of its use as a neurotransmitter (but I’m absolutely going to look into it now), but its barely soluble in water so there must be more going on there. just like urea, it’s a natural waste product, and typically one your body wants to get rid of reasonably quickly.

Yikes that’s almost as bad.

When you’re supposed to choose between siding with the Mages and Templar, it tells you to go back to the war room, which I assume should activate some kind of cutscene…but nothing happens. You just get to choose more missions on the map. I can’t tell how far back it bugged out, even if I go back to before starting that questline, I get the same issue.

I was playing through Inquisition for the first time earlier this year, and 30h in the main questline broke, and I cant proceed…a real bummer.

- Comment on The 1900s 2 months ago:
In chemistry a lot of the foundational synthesis and work is as old as the 60s and 70s; people build on it, but in some cases those early papers said pretty much all there is to be said on a topic, so there’s no reason to republish on it.
I’ve had to cite papers as old as the late 30s before, because no one has ever found anything to fix or correct about their work! Pretty impressive if you ask me, given how few tools they had.
- Comment on Publishers Always Innovating 2 months ago:
Truly. Also the springer nature ones load so slowly for absolutely no reason, and break 10% of the time. I really don’t get what their motivation is, do they think that after I’ve said no, I dont want a web version, I will be happy with a different web version?
- Comment on Integer addition algorithm could reduce energy needs of AI by 95% 2 months ago:
Good point. Though, the vast majority of ML training and use is tensor math on floating points, so largely dot and cross products, among other matrix operations.
- Comment on Integer addition algorithm could reduce energy needs of AI by 95% 2 months ago:
I think you’re thinking of the famous fast inverse square root algorithm from Quake.
With respect to the top comment, the only reason 3d graphics are possible (even at 850W of power consumption) is due to taking a bunch of shortcuts and approximations like culling of polygons. If its a reasonable shortcut it either has or will be taken.

Yeah if that’s not on-brand for Intel, I don’t know what is! I wonder what the max power draw for the 14900H is, it’s gotta be close 😂
