    That’s a misconception. The Maya (not Mayan, that’s the language) long count for December 20, 2012 was 12.19.19.17.19. December 21, 2012 was 13.0.0.0.0. Today is 13.0.11.7.4. It continues the same way indefinitely, it’s just the number of days since some arbitrary date (August 11, 3114 BCE if you’re curious) in base 20, with the second to last digit in base 18, which seems odd at first but it rather cleverly makes it so the third digit can stand in as a rough approximation of years, and the second is approximately a generation. Now October 13, 4772 could be seen as an endpoint but there’s nothing that says it can’t be extended with one more digit to 1.0.0.0.0.0, and then you’re good for another 150,000 years or so.

    Now there was a creation myth that said 0.0.0.0.0 was the previous world’s 13.0.0.0.0, but there was no recorded belief that this was any sort of recurring cycle, in fact plenty of Maya texts predicted astronomical events millennia past 2012. The idea that it was recurring was probably borrowed from the similar Greek construct of ekpyrosis, which doesn’t specify any sort of time frame.









  • 4 degrees is the apocalyptic scenario. The vast majority of oxygen in the atmosphere is provided not by trees or any plants, but by the algae and cyanobacteria in the ocean. At the 4 degree threshold, they can’t do aerobic respiration anymore, so they switch to anaerobic respiration. This means they stop producing oxygen, drastically reducing the amount of oxygen in the atmosphere and drastically increasing the carbon dioxide. This does two things: kills any large fauna, humans included, and the additional carbon dioxide continues to act as a greenhouse gas, accelerating the effect even further. Eventually, after almost all oxygen breathing life is dead, we reach equilibrium, assuming your definition of 'we" includes insects, because that’s basically all that would be left. If there’s a risk of reaching the 4 degree threshold, we would be forced into taking our chances with the literal nuclear option of deliberately inducing a nuclear winter.


  • The Doomsday rule.

    Not necessarily the part for calculating the day of the week for any arbitrary day centuries ago, that’s just a useless party trick, but for the current year so you don’t need to pull out your phone to check. Knowing that 1/3 (or 1/4 on a leap year), the last day of February, 3/14, 4/4, 5/9, 6/6, 7/11, 8/8, 9/5, 10/10, 11/7, and 12/12 are all the same day of the week, that this year they’re all Tuesdays, and next year they’re all Thursdays, is mostly easy to remember and very frequently useful.


  • My guess is it was part of a two-pronged election strategy. First, make COVID denial part of the GOP’s political platform, so that they’re more likely to be performatively reckless, including waiting on line in crowded polling places where no one is masked (which goes further to scare people away that were actually taking COVID seriously), while people taking precautions like voting by mail or by voting early when it’s less crowded would be disproportionately likely to vote Democratic.

    Then, pass unreasonable regulations like “mail-in and early votes can’t be counted until all votes cast on Election Day are counted”, while pressuring election workers to post results as early as possible, skewing votes in their favor, or, failing that, point to the fact that the votes against them were counted later as evidence of fraud.
