  • There are a lot of concepts in mathematics which do not have good real world analogues.

    i, the _imaginary number_for figuring out roots, as one example.

    I am fairly certain you cannot actually do the mathematics to predict or approximate the size of an atom or subatomic particle without using complex algebra involving i.

    It’s been a while since I watched the entire series Leonard Susskind has up on youtube explaining the basics of the actual math for quantum mechanics, but yeah I am fairly sure it involves complex numbers.


  • The explanation I’ve seen is that … is notation for something that can be otherwise represented as sums of infinite series.

    In the case of 0.999…, it can be shown to converge toward 1 with the convergence rule for geometric series.

    If |r| < 1, then:

    ar + ar² + ar³ + … = ar / (1 - r)

    Thus:

    0.999… = 9(1/10) + 9(1/10)² + 9(1/10)³ + …

    = 9(1/10) / (1 - 1/10)

    = (9/10) / (9/10)

    = 1

    Just for fun, let’s try 0.424242…

    0.424242… = 42(1/100) + 42(1/100)² + 42(1/100)³

    = 42(1/100) / (1 - 1/100)

    = (42/100) / (99/100)

    = 42/99

    = 0.424242…

    So there you go, nothing gained from that other than seeing that 0.999… is distinct from other known patterns of repeating numbers after the decimal point.




  • Jesus fucking god.

    Anderson Cooper is talking to Kamala.

    After Kamala basically explains some actual achievements of the Biden administration while refusing to address Biden’s incoherence…

    Cooper says “Yes but neither candidate explained what you just said so succinctly and quickly.”

    This is after Kamala has been stalling for almost an hour. When she comes in screen she’s twirling her hair nervously and does it again, unable to even crack her immensely fake smile a single time.

    MSNBC and CNN basically are either in shock or reporting on the entire Democratic party being in shock.

    With MSNBC, after most of the panel talks about the possibility of Biden resigning Maddow just got into an argument with some other talking head over whether or not its possible for Biden to bow out, as the other person says yeah it actually is technically possible.

    To sum up, Cooper asked Kamala if Joe is like this all the time.

    She did not say no.

    What an astounding fuck up.


  • I think it was his third time speaking… he was answering one question on one topic and basically accidentally started talking about something else and then was visibly confused as he realized he was making no sense.

    I am legitimately going to need to read a transcript of this to figure out wtf he was talking about half the time.

    Like… Biden was just asked if his age would impact his presidency.

    His response was to mumble about being the youngest person in politics originally, and uh we are building more chip fab plants, and America is awesome.

    Trump is now answering the same question and is actually staying on topic for his entire answer though he’s lying a bit.

    And Joe just went back to mumbling about how Trump is actually 6 foot 4, or 6 foot 5, or well anyway he couldnt carry his bag while golfing.

    Yeah… Biden is very much coming across as a near senile grandpa and Trump is coming across far more well composed.


  • Yeah, its infuriating that punk has become a suffix.

    There is nothing punk about steampunk, dieselpunk, atompunk. They are just fantasy technological scenarios / art styles.

    Cyberpunk has an both a recognizable aesthetic and a whole lot of political, social and philosophical views baked into it. You get the punks in cyberpunk as either a direct ideological opposition to the power of corporations, or as an indirect result of said corpos creating a hell world for 99% of people.

    There is nothing inherently rebellious about worlds or characters within worlds with more prevalent / advanced steam or diesel or nuclear power.

    Solarpunk arguably has some actual punk to it if you actually try to follow the idea of personally minimizing your fossil fuel usage, but mostly its a utopian or post-dystopian setting / art style.

    Its now like -gate being affixed to any kind of publicized controversy.

    Most people do not understand what Watergate even was and why it was so significant.







  • I’m from the wet side of the PNW and we have all of those as well, excepting possibly northern widows, I’ve not heard of those.

    I’ve spent weeks in cabins and lived in houses and apartments all over WA.

    Every single time I have ever seen a spider in a house or apartment, its been something that is totally harmless to humans.

    Out in the boonies? Sure, thats where you’ll actually run into some dangerous things.

    That being said, I’ve never lived in MN, perhaps dangerous spiders are a more serious threat in urban/suburban areas, and yeah, climate change fucks up everything.

    Something absolutely absurd started happening a few years ago, right in the middle of Seattle, like 2 blocks from a main road:

    Coyotes.

    I’ve seen coyotes out in the foothills occasionally, on trails far from cities, in the brush on the east side of the state.

    But… basically that heat wave a few years back, and wildfires and droughts managed to drive a population of coyotes into residential areas of Seattle, likely hunting the rabbits.

    That was pretty stunning to me.





  • Unless I am mistaken, aren’t basically every kind of Tarantula you can keep as a pet non venomous?

    I’m the kind of person that’ll take basically any kind of spider save a black widow and just put it outside while my gf is screaming at 115db to murder it and will then be angry with me for 3 days that I didn’t.

    Poor tarantula.

    Oh right, this ‘politician’ is an amazing argument for lowering housing costs such that people can afford studios instead of living with crazy ‘main character’ people like this.


  • Its possible they could last long enough for some kind of rescue mission, assuming they were in the cabin and not blown out into space.

    Fairly sure the payload bay does not have windows.

    Or they may have been able to rendezvous with the ISS and live there, assuming the damage was only to the shuttle bay.

    They’d certainly die if they attempted to re enter the atmosphere.

    Though, judging by how small the earth is… they seem to be significantly higher in earth orbit than any shuttle missions I am aware of?

    Nah, it was my handwriting, used the same lingo and joke I remember using at the time, took up most of the board… which is why I was so shocked it hadn’t been erased.

    Most of the time people wrote on it, they were gracious with the space.

    Due to typing far more often than writing, and many years later me figuring out oh haha I’m actually naturally left handed, my writing is a fairly uncommon kind of small cap block print, otherwise I am basically the only one capable of reading my non block print scribbles.
