  • Yeah, I think the battery thing OP pointed out makes more sense than the power argument. The Z1 extreme used in other handhelds is based on the 8840HS iirc, anf its at least one generation newer than the basis for the steam decks somewhat custom silicon.

    The Deck processor is 4 Zen 2 CPU cores and 8 RDNA 2 GPU CUs, while the 8840HS is 8 Zen 4 CPU cores plus 12 RDNA 3 graphics CUs. It’s going to be wildly more powerful. The 8745H actually has the same CPU and iGPU configuration as the 8840HS – not even close to steam deck specs.

    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.

    Doesn’t 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).



  • 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 there’s 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!
