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.

I am if and only if I am.

Any ban of a political party includes "successor" parties/structures. If a large number of politicians from a banned party joined another, that party is likely to get banned too.

It won't fix the issue but it provides room to breathe. A ban is preferable over doing nothing any day of the week.

Zweibel would be two Bel (or two Decibel, converted to the better known unit) if you forgot about your space key.

Surely you mean Zwiebel.

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 the neat property: erf(-x) = -erf(x)

You could replace erf(x) with an integral but this would be illegible without LaTeX.

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.

To expand a little:

For a much smaller sample size of just 1 million, the probability to lose just 1% off of the median is basically zero.

WolframAlpha doesn't even bother to calculate the exact result and just rounds it:

To be fair, people with tumors behind their ears will likely hide it to avoid assholes staring/taking pictures. I don't see many cancer patients attending chemotherapy either because they are wearing hats/wigs.

Still, shouldn't they get cancer on their hands instead? That's the closest body part to your phone at any time on average, isn't it?

The walls of the echo-chamber have been built up and reinforced for over a decade. No single election cycle will ever pierce through.

These people are lost causes unless a massive culture shift happens. And it's not looking like that will happen in the next decades. You, just like other countries, will have to deal with a growing strong block of far right, young men who will grow up to be far right seniors.

The warning signs started being obvious with Gamergate but they were ignored. The only thing that can be done is preventing the growth of these echo-chambers but the damage is done. It's just like how carbon capture will not solve climate change, only stopping emitting more as soon as possible.

That... doesn't seem overwhelming?

In the city council election I voted in (Germany) you had ~40 votes (don't remember the exact number) to distribute among candidates. Each party put up to ~40 candidates on the ballot and you had to distribute your vote among the candidates. You received like 10 ballots, with each party being on a separate one and had to cast your vote in an envelope with the relevant ballots.

Additionally, you can give up to 3 of your votes to any one candidate by putting a digit next to their name or just cast one party's ballot without entering anything to give one vote to each candidate on that ballot.

Sure, it sounds complicated but you received the ballots with some information two weeks before the election and were encouraged to bring them filled out to the polling station (to reduce waiting time) or register for mail-in voting. Most people probably just casted their entire vote for one party anyways.

I'm a cis guy, so feel free to ignore everything I said. Though I do want to comment because I have experienced something similar (except not in regards to gender.)

My strategy to cope with it is to take a break from whatever I was watching the instant I start experiencing this and just allow myself to feel sad for some time. I don't think ignoring these emotions helps, so I'll bury myself under a mountain of plushies until the negative feelings pass. Once I feel better I usually don't have any issues with continuing the video/movie/series and actually start enjoying it again. After all, I actually want to watch them. Also, after feeling like I'm capable of rational thought again it helps to question myself why I felt upset and to think of "counterarguments" that contradict the negative thoughts.

Your mileage may vary but it can't hurt (except momentarily) to give it a try.

There's no problem with piracy if you never ever ever intend to subscribe to a streaming service though. Give me the option to pay for DRM-free .mkv files with differing qualities and bit rates and I'd consider not pirating, provided the prices are reasonable.

You'd be forced to learn Assembler because for some reason that's the German translation of Assembly.
