  • I remember being kinda excited for the tv-series, since Peter Lustig would dub the inventor in the German version (I am sure that was part of the advertisements). Peter was already famous for his roles in educational science programs for children, so having those shows in animated form with cute mammoths couldn’t possibly fail.

    I think I only ever watched the episode on water pressure. Usual problem of it only being on Tv while I was at school.

    …well would you look at that, not only did I watch at least 2 episodes, but I also learn that the episodes about gravity and blimps is called “the far side”.





  • When a drivers license is taken or suspended, especially for speeding in cities, give an easy option to directly… lease(?)1 an e-bike. And then suspend licenses for a lot more of the dangerous behaviors we currently just accept.

    A relative got her license suspended for a month for speeding, and then simply did not go anywhere. Having an exciting new mode of transport might have just been what she needed, the supermarket is just 2km away.

    1: The state can hammer out the details, obviously we don’t want to gift them it or it becomes a reward for speeding, and selling them it means they could just resell it afterwards when the goal is that they keep and use it. Maybe like a 5 year ban on reselling it, only one per household. Also, probably keep the model generic and discreet so no shame is cast when just trying to buy groceries.





  • I never said that. What I meant is that a behaviour, which benefits a species as a whole but reduces one individual’s fitness, is not evolutionary competitive. It’s evolutionary game theory, like the prisoners dilemma from normal game theory.

    And to determine if some behaviour is such a dilemma, you have to consider costs and benefits of it, which is not at all clear in natural situations. That’s why I said it needs to be studied.

    But I must concede, I sort of assumed what exactly you called an evolutionary advantage. Common homosexuality in penguins or not discriminating against homosexual individuals in penguins have very different analysis here.

    I’d be cautious with saying evolutionary advantage here.

    I don’t believe the “Gay Uncle hypothesis” any more than the somewhat debunked “Grandmother Hypothesis”, which aimed to explain menopause with biological altruism. Just because we could think of a way in that it might be advantageous for a species doesn’t mean it’s advantageous for an individuals fitness.

    Of course, it can be still an advantage, but we’d only know with more free, uncensored research.

    This bike lane is on the left side, but the bike lanes in the rest of the city are on the right. Someone then thought the best way to connect them is to have them cross 2 streets to get to the bike path leading to the right, and from there take 2 left turns if they want to go left, which also has a separate lane for right turns - just for the cars, of course, so that is another lane bicycles need to cross.

    So, depending how the traffic lights work, bicycles have to wait up to 5 times to do a simple left turn. The traffic needs to flow after all, and traffic just means car traffic to some city planners.




  • I think that is thinking a bit too narrow. A lot of the stuff we use today might just be our bronze to our successors iron - you can build an unstable society on either. And what we do use up today could still work if used more efficiently - we might not have enough rare metals to give everyone a smartphone in the post-post-apocalypse, but I could see us still launching satellites if only big governments had computers - because they did.
