  • 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.







  • 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.





  • There’s nothing to lose by trying as long as you accept that the worst case scenario is they’re still not part of your life.

    Maintaining relationships is hard. They’re likely minimally social these days as well. Somewhere around your age is where many people suddenly feel lonely. It’s a tough lesson on the concept of “friends of proximity”. That’s usually a negative term, but, quite frankly, I believe all friends are friends of proximity. If you change proximity (new job, differetlnt school, drop a hobby, move, etc), you have to work harder to stay in each other’s orbits. Shortened tangent: this is something I’m at peace with now. Instead of putting asterisks next to everyone that’s a work friend or hobby friend, they’re just friends. I don’t know when that friendship will end, so I focus on enjoying the current relationship.

    The point I’m coming to is that, while I understand this is a unique situation for you, it’s a common general feeling. That will make it tough to rejoin social circles that likely don’t exist anymore. But, if you do manage to meet up, have at it. Enjoy it. Perhaps there are other people in your orbit that can be reevaluated as a friend. Maybe you can find something to do with them, even if it’s just a very basic hangout after work or something. I find many people are hesitant because they also think of these friendships as temporary, but hopefully you can get a feel for options and feedback. I know your post was about old friends, but I’m hoping they’re not your only option.

    And please, please, do not take social media posts as their daily diary. It’s so hard to accept, but every day they’re not posting, they’re just as bored and alone as everyone else scrolling. Social media is the high lights reel. So much of it is projection.
