    And by leeward I mean windward. /facepalm

    Higher loads. Oversimplified summary: Has to be able to lift half the weight instead of a quarter. Higher twisting loads due to longer ww hull.

    In theory it could combine a decent amount of form stability (from a wide leeward side) with a high l/b (while heeled) and self righting. Pays the price of shunting, but that's still a nice combination to have.

    A danish (I think) guy build models like that. I find it quite intriguing in theory.

    So am I. Why is the bern where the stow should be?
  6. Okay, sorry. I was under the assumption you weren't insane. Obviously I was mistaken.
  7. So do me a favour and don't. I've worked with refugees and none of them left their home for fun. Many of them have been through unspeakable horrors and they deserve every bit of help they get and then some.

    Shhht, don't tell them they have basically the same ideology or they will ally up.

    Still better than our navy. 135 million € repair bill so far and she's still in a yard.

    Gladly I didn't have to take econ classes. The logic for philosophers class was infuriating as it (basically) assumed all sets to be non-empty. The book for that class is 250 pages of headache inducing gibberish.

    Reminds me of a coeds story about her horrors in maths for economists. "Why is the derivate of fixed costs equal to zero?" Which lead to half an hour "philosophizing" before she got picked. Math students in "logic for philosophers" was another fun one.

    I'd rather call them strictly criminal standards.

    Maybe, but I've seen a lot of kids suddenly get it, if you change your angle of explanation a bit. Fractions are a difficult subject for many and there's multiple ways to explain them. One of them usually works and in my experience it's mostly the "Okay, forget what you've been tought about division, because it doesn't exist. 1/4 is a brand new number we made up and 1/4*4=1" approach. At least for adolescents. That said some math teachers are just trash. I do pro bono math classes for autistic kids and used to do them for refugees. The materials I see from other teachers can be infuriating. An exam (!) full of ax+b=c. No assignment. No question. Quite obvious (s)he didn't spend more than 5 minutes on that.

    Was a bit of a rushed extracurricular project to program a representation of the mandelbrot set, after we had finished the curriculum, so I can't blame him. My math teacher at that time was one of the best teachers I ever had. Great mix of good explanations, humour and giving us space to explore concepts on our own. We regularily hit him up for physics explanations, when we didn't get the explanations of our physics teacher. He also tought us a lot of maths other students did not learn. I was quite bewildered at my coeds at uni several times. "How do you not know what a group/field/etc is?!?" Anyway, I think there should be two teachers in a classroom at all times. Seems strange that we don't provide collegial feedback in a profession so important.

    Teacher's prejudices having an impact on their students is pretty well known. Therefore I think students should have as many teachers as possible. This also helps with antipathy between students and teachers. Having the teacher I had the worst relationship with all the time sounds like a nightmare. Sometimes a slightly different explanation also helps a lot. I didn't really get complex numbers in school. The explanation at uni changed that quickly.
  17. We're just making fun of you mikey, because you spam PAGES of blah whenever you think someone is wrong. Noone here cares whether it's centrisomething force.

    It's possible to have someone else register your place of residence for disabled persons who can't do it themselves or similar cases, I guess. But generally you'd go to the cities office with your ID and a statement from your landlord or contract about the purchase of property to get your new place of living registered. You'll automatically be listed as a voter at your new place of residence and purged from the voters list at your prior home. States require some time of residency (6 months?) before you can vote in state elections so people can't state hop to vote. Happened to me in 06, when I moved to Hamburg and couldn't vote in the state election. Might have been the county election, not 100% sure. Uhm, on topic: math education can be racist and curricula should be checked. Math departments at universities could use some more poc and women.

    You must register where you live, there's a non trivial punishment if you fail to do so. The voter registration is automatic. Homeless persons can apply for the voting register seperately.

    Uhm, it's the federal republic of Germany. With 16 states. With their own parliaments and so on. We track that with an Einwohnermeldeamt. Great idea. You should try it. If you aren't registered with it, you're not going to get the letter needed for voting and your name isn't going to be on the voters list anyway. From my understanding you need to be registered as a voter to vote in the US aswell. Obviously there are always going to be some mistakes with lists not being up to date, but that's not fraud. Fraud implies intent.

    Your maths isn't wrong, but no one does it that way like ever... Especially as it ignores the number of eligible voters going up as well. That's why it is more usual to speak about percentage points. As for the voting by mail, we have the same idiotic arguments from the right wing in germany. Do you seriously believe the people setting up voting by mail are too stupid to set up basic failsaves like a unique ballot ID matched to a voter? Where are the people complaining of not recieving their ballots if someone else used it?

    The english wiki states 23 million additional votes which is roughly 7 percentage points higher turnout. The german wiki, which I looked at first, states 12 million/2 percentage points. Anyway you are avoiding the point: How does a higher turnout statistically prove fraud? Was there fraud in 04 aswell, when turnout jumped up 5 percentage points? How huge must the fraud have been in german elections for the european parliament when voter turnout jumped up 15 percentage points?

    That site does not contain any calculations regarding what you said. 30 seconds of googling found voter turnout not increasing by 30kk but by 12kk, tho. An increase of ~2% which fits with the pattern of increased voter turnout since the 90s. The site you linked speaks of ~1100 cases of election fraud. It is unclear whether they are all from the 2020 pres election. Even if they were, they wouldn't change the outcome. Overall I rate your statements BS for bullshit.
