  • fun fact, days have actually been getting longer pretty much since formation of earth (well moon to be correct). reason iirc is that moon is slowly moving away from earth, and this results in some dynamics changing and as a result earth spins slower. like billions of years ago, it was closer to 23 hours.

    ps - very rusty memory right now, should have skipped writing instead of half borked fact

    adding to this comment, the best way that we currently know how to extract this energy is using spinning black holes, with theoretical efficiency of ~42% (answer to the universe)(src: a minute physics video precisely on this). the naive solution to just touch them gets like 0.01-0.1% of total energy, so in bad case, we need trillion years.





  • well i seemingly have a very different viewpoint, because the most interesting economics bits are econometrics, essentially data science - the same things all other stem folks use to find the underlying distribution, estimators, their significance, finding the p value. Using this to model whole world is just as wrong as saying all of chem is solved by taking mendelev periodic table. sourely it works, and explains some stuff, but just knowing it does not predict all of chemistry. same way, for example ls-lm model (suppply demand curve) does not explain the whole world, and good economists do not claim they can explain it (sorry for using bad examples, 1 only took 2-3 eco courses).



  • I seemingly have a rverse take - I much prefer the latter. i just do not use threadiverse, i use places where !/@ means something totally else (for example in programming ! is not and @ can be used for different purposes, but in my shell, @ sigil is used for arrays). the latter is very clear to me - /c/ is comm and /u/ is user. a bit more verbose (3 characters vs 1) but not that much but much more readable for someone comming from outside or who context switches.
