  • Sure. Except if you allow those in power to define the meaning of demos, every single country that ever existed - including Nazi Germany - was democratic. As a result, the term democratic becomes tautological in that it is always true regardless of the system involved.

    So yes, your statement that China is a nation is true.


  • I don’t think that’s why kids hate it. Rather, teachers fail to explain the underlying motivations, the reasoning and the purpose which makes math feel like arbitrary decisions.

    I’d argue math is much more uncertain than other subjects. What’s the purpose of the endoplasmic reticulum in your cells? Just memorize the textbook. Find all X such that [statement] is true? You better have some creativity! Or a lot, depending on the problem.

    Some accompanying evidence for uncertainty: https://xkcd.com/2117/




  • I’ve found a proper approximation after some time and some searching.

    Since the binomial distribution has a very large n, we can use the central limit theorem and treat it as a normal distribution. The mean would be obviously 500 billion, the standard deviation is √(n * p * (1-p)) which results in 500,000.

    You still cannot plug that into WA unfortunately so we have to use a workaround.

    You would calculate it manually through:

    Φ(b) - Φ(a), with
    b = (510 billion - mean) / (standard deviation) = 20,000
    and
    a = (490 billion - mean) / (standard deviation) = -20,000
    and
    Φ(x) = 0.5 * (1 + erf(x/√2))
    

    erf(x) is the error function which has one good property: erf(-x) = -erf(x)

    Therefore:

    Φ(20,000) - Φ(-20,000)
    = 0.5 * [ erf(20,000/√2) - erf(-20,000/2) ]
    = erf(20,000/√2)
     erf(14,142)
    

    WolframAlpha will unfortunately not calculate this either.

    However, according to Wikipedia an approximation exists which shows that:

    1 - erf(x) ≈ [(1 - e^(-Ax))e^(-x²)] / (Bx√π)
    

    And apparently A = 1.98 and B = 1.135 give good approximations for all x≥0.

    After failing to get a proper approximation from WA again and having to calculate every part by itself, the result is very roughly around 1 - 10^(-86,857,234).

    So it is very safe to assume you will lose between 49% and 51% of your gut bacteria. For a more realistic 10 trillion you should replace a and b above with around ±63,200 but I don’t want to bother calculating the rest and having WolframAlpha tell me my intermediary steps are equal to zero.




  • Don’t worry, the youth will only become further right-wing.

    Here’s the result of a local German state election from September. It displays the results for people aged 18-24, divided into male (light) and female (dark). AfD is openly fascist. No other age group voted for them as much. Getting 46% in a system with proportional representation is basically unheard of by the way.

    I very much suspect this trend will continue.


  • Why then do countries with existing left parties and proportional representation elect further and further right-wing parties in Europe?

    It’s simple: They promise easy solutions for complicated problems. Banning immigration will fix all crime and the economy, opposing LGBTQ+ rights will ensure a return of the better olden days, climate change is nothing to be worried about etc etc

    And even people depending on social support will gladly shoot themselves in their feet if it means someone else will have it worse.
