When the great pyramids were being built there was still woolly mammoths walking the earth.

    Humans can’t feel wet, what we’re actually feeling is cold. It’s why when you have a cold patch on a blanket or carpet you can’t quite figure out if it’s wet or not.

        Let $\mu(x)=0$ if $\exists y<x\mu(y)=0$ or $x$ is the 20 millionth prime. $\mu(x)=\mu(x+1)+1$ otherwise. The elements of the sequence only become defined once the 20 millionth prime is found; till then they’ve yet to be constructed.

        Bonus: The sequence $\nu$ is defined as follows.

        Let $\nu(x)=0$ if $\exists y\leq x\mu(y)$ is perfect. $\nu(x)=\nu(x+1)+1$ otherwise.

        We’re not sure if this is a sequence, even though it is algorithmically definable. Its existence relies on the existence of an odd perfect number.

    There is no thru line from mouth to urethra. You drink water, it gets absorbed into your blood, your urinary system filters excess water and waste, you pee it out. Your pee is filtered blood, the only thru line for water to take from your mouth is your ass. I understood that when it was taught, but I didn’t really think about it…

    Useless knowledge.

    When playing Mechwarrior 2 on a Windows 2000 system, make sure to change your video mode to 32bit color.

    I’ll throw in a useful tip too!

    You can buy USB foot switches for your computer and assign keystrokes and other functions to them.

    Almost feels like cheating when you are playing a tactical shooter and can lean left or right and strafe on demand without crossing any controls. Having microphone activation, map, inventory, or any number of misc actions boud to a foot pedal makes a huge difference in your ability to play a game.

    The people who got anime to take off in the US are the same people who started the furry fandom.

    The Superman symbol was based off of the symbol for a sci fi fan club.

    Conventions, and sci fi as we know it, are because of one electronics magazine.

    The guy who did localization for the Zambak magazine’s Turkish translation of “the alice in wonderland” has the cool birthday January 1st, 1969.

    (Might’ve been another magazine, could not find a picture online)

    With vanishingly rare exception, addicts choose the mood altering substance that is closest to what the medically accepted treatment for their underlying disorder(s) would be.

    People who are addicted to alcohol, without exception, have an underlying anxiety disorder.

    People with ADHD and similar brain functioning tend to choose amphetamines.

    The list goes on and it gets very complicated, because most mood altering substances have multiple effects, and most people have a blend of underlying issues. But the point is, there is a very noteworthy observation there, I feel.

    I feel qualified to say this as myself I am 11 years sober and have worked in the field of addiction for 8 years and I’m formally educated.

      I have ADHD and I trend to get into a comfortabele alcohol Buzz every evening because it shows down the train of emotions. Amphetamines don’t really feel good, nor do other drugs. I hate speed and weed.

    The aging sun will make the continental drift stop via increased solar activity which will accelerate rock weathering. This will break the carbon cycle long before the earth is absorbed by the sun going in its red giant phase.

      UPDATE: the wiki has been updated! “However, a 2024 paper by RJ Graham et al. argues that silicate weathering is far less temperature-dependent than initially thought, and that falling carbon dioxide levels are unlikely to lead to the death of life on Earth” yay!

    Dont do this.

    You can hurt yourself if you grab the top of your thumb with the fingers of the same hand and make a motion like youre banging a hammer with your wrist.

    Dont do this.
