  • Same, especially because I’m a frequent sky-looker but have to prepare any ride-along that all we’re going to see by eye is pale fuzzy blobs. All my camera is going to show you tonight is pale sprindly clouds. I think it’s neat as hell I can use some $150 binoculars to find interstellar objects, but many people are bored by the lack of Hubble-quality sights on tap. Like… Yes, and then sent a telescope to space in order to get those images.

    That being said, I once had the opportunity to see the Orion nebula through a ~30" reflector at an Observatory, and damn. I got to eyeball about what my camera can do in a single frame with perfect tracking and settings.





  • Yes, that would be one way to make it noticeable. If all land/sea floor lifted, gradually, 1.2km into the air, we wouldn’t see it. I also Flubbed the per-km increase of the ruler and edited it to correct the increase down to 20cm per km. So as far as our ability to tell things are 0.02% further, no mere mortal would recognize it. But with a lap band around the Earth, we’d definitely notice the new halo floating above us instead of being a tripping hazard.

    That reminds me of a fun fact about how the increase in circumference does not care what your starting values are. If you wanted to wrap a rope around a soccer ball, then make the rope lift 1m above the surface of the ball all around, you’d do probably do the pid math like (pid2)-(pi*d1) :

    3.140.022m=0.069m of rope around the ball
    3.14
    (0.022+1+1)=6.349m of rope to float 1m above the ball
    6.349-0.069=6.28m of extra rope

    Then do it for the planet.

    3.1440,000,000m=125,600,000. 00m of rope around the planet
    3.14
    (40,000,000+1+1)=125,600,006.28m of rope to float 1m above the ground 125,600,006.28-125, 600,000= 6.28m of extra rope.

    1m above, or 2m greater diameter, can just be fed directly into pid as derived from pi(d2-d1) since we know it’s a basic request to lift it 1m


  • 67% of the Earth’s mass is comprised of silicates in the mantle. Solid silicates have very low thermal coefficients of expansion, meaning they change volume very little in comparison to other compounds. So if the mantle was cooled and solidified to 0, then heated to 50, it’d have very little effect. It’d grow something like 0.02% in volume.

    Being that the mantle is generally liquid, you’ll see a much larger effect from the initial cooling. But how much? I don’t know. Liquid rock isn’t present in mere mortal online calculators and my ability to dive into the material properties and manually calculate it is long gone from my head.

    But “much” larger may not be significant to the human experience, given that 0.02% would be imperceptible as a baseline. If you had a 1km long solid silicon ruler, heating it from 0 to 50C would make it just (edit) 0.2m longer. A circumferential ruler reaching around the Earth along the equator would go from ~40,000km to 40,008km.

    Edit: corrected 20m to 0.2m. Flubbed the percentage in the calculator as 0.02 (2%) instead of 0.0002 (0.02%). So really, really imperceptible to a human walking 1km


  • I take it the Switch/S2 has many non-Nintendo games shared with other consoles? Hard to search through 4,000 titles on Wikipedia to find them at random, but I did see they had one Assassin’s Creed (Odyssey) at the game’s launch. I never really had Nintendo systems and just associate them with exclusive Nintendo games.

    I’m choosing to believe the Steam Machine will do more of the same for PC games. Maybe it won’t force optimization at launch, but I hope it maintains itself as a benchmark for builds and provides demand for optimization to a certain spec.


  • OK, so you don’t have fossil-fuel-free solutions, either, and you don’t have a reasonable plan to handle night time energy needs. You specifically said that utilizing fossil fuels at all was an issue, including for production of renewable, with the claim about not being able to source a turbine without fossil fuel use. It sounds like you don’t understand that “night” happens during normal human waking hours, that there are actual activities and demand for energy specifically at night, and that there is no direct path to a fossil-fuel-free energy solution. I have no idea how subsidizing alternates erases fossil fuels for your idea.

    Its the winter solstice in the northern hemisphere and I have 8.5 hours of daylight today. That’s about 4 hours of decent solar production without clouds, since the sun is so low. I guess I’ll just try sleeping, without electric heat (since CNG is a fossil and solar is dormant), for 14 hours tonight from dusk to dawn (5pm-7am). Wait, solar panels are still using fossil fuels for production, so those are out. Is a wood stove OK? It’s renewable, but it’s a major CO2 burden, much worse than CNG. Can’t mine lithium or nuclear material with the existing industry, all runs on petroleum. I’m not sure if life is worth living, as every waking hour has been spent at work, using the small time frame to try to support myself financially.

    This also means no activity can occur at night. No manufacturing? Triple the facility sizes to allow the “night time” morning shift and the “night time” late night shift to operate with the daytime shift. Can’t go anywhere, can’t entertain myself, can’t eat, can’t enjoy anything other than lying in the dark, waiting for the sun to come back. That’s weird, putting all the overnight demand in the daytime is causing brownouts because we couldn’t triple our energy production. But hey, the burden is being shared and we’re all miserable for 5 straight months. But the summer will be rad with only demanding 8 hours of dormancy.

    Look at the project. It’s not a continuous production of CO2. It says this one contains 2,000 tonnes of CO2 and produces 200MWh/day. A CNG power plant is somewhere in the range of 0.5kg CO2/kWh. That’s 10,000kg CO2 from CNG for 20MWh, or 10 tonnes. In just 200 days, a CNG plant of the same capacity will produce as much CO2 as this entire facility contains.

    Bashing innovative projects like this for being anything less than a time machine to go pure nuclear actively hurts progress. Is that your goal? To maintain the status quo?








  • This is pretty much what I was going to say. You always lose material, but the amount lost varies drastically based on the method. Even when using a knife or shears in a purely straight motion (no sawing or sliding), the material has to deform to make room for the cutting device. It may rip apart, it may bulge into itself, it may crumble, it may do it all. Try cutting a thin slice off a nice block of cheese and you’ll see nearly all the deformation go to the slice, while the knife will be coated in cheese






  • I dunno, he was in Scream 6 and will be in 7 since apparently they want to keep going with this series. I still see Ghostface masks every year at Halloween. But, sure, I can agree his presence in the movie isn’t as culturally significant.

    On the flipside, Shaggy is an existing character to me that happened to be played by Lillard in later adaptations. He’s not the face of Shaggy to me because Shaggy was a cartoon first.

    But that’s my take.
