  • Hvordan ser det ud på Feddit.dk? Bruger I museer?

    Ja, men det er mest som familieaktivitet og ferieunderholdning til børnene.

    Jeg gad egentlig godt at museer blev lidt mere hardcore mht. til at udstille den enorme viden som ligger bag udstillingerne. Det bliver ofte en lidt tynd omgang, hvor de har forsøgt at lave interaktive udstillinger eller oplevelser med lydfortællinger som er drønende kedelige og samtidig så overfladiske at man intet lærer. Jeg føler lidt at jeg kommer på skoleudflugt når jeg går ind i et museum. Det er selvfølgelig fint at man kan nå at se det hele på et par timer, men der mangler mulighed for at gå lidt dybere, hvis jeg skulle have lyst til at komme oftere og i længere tid.




  • I think any aliens advanced enough to visit Earth would probably understand it.

    Whether it’s horror movies or extreme sports, it is some kind of play, which is about creating a safe or controlled environment to explore things that either isn’t really happening (horror movies) or things that haven’t been tried before (extreme sports).

    A lot of extreme sports are actually relatively safe because it’s done by individuals in highly controlled environments. Statistically it’s a lot more dangerous to participate in other sports or everyday activities where there’s a larger risk from other participants or things that are unpredictable. Things like horse riding, traffic and trampolines are more dangerous because they’re more unpredictable. The consequences might be worse if it fails thoughm, making it “extreme”.

    Travelling through space to explore inhabited planets absolutely requires the same kind of desire and process of safely testing out things that are potentially dangerous.



  • I’ve seen the same kind of visualization made from different sources before showing the same point. There is really nothing shocking or unbelievable in the picture?

    It’s fine to be sceptical because it is an estimate. However it is a qualified estimate. Read more from the source: https://www.prb.org/articles/how-many-people-have-ever-lived-on-earth/

    If you have a better way of estimating the figure, I’m sure they would be all ears.

    I do remember reading school books and science articles 30-40 years ago and the estimates then were different, but that’s just how science works.

    Again it’s fine to be sceptical, but unless you can provide an alternative figure with better documentation, I really don’t understand why you’re encouraging people to be sceptical.

    It’s almost as if you seem to have different motive, so I have decided to doubt your scepticism.


  • That’s pretty much the point. We could’ve had vehicles that could drive over rough ground, but they opted to make flat roads and rubber tires, both of which are causing issues environmentally and congestion.

    My whole thought experiment is : If you were to settle a brand new world, would you repeat the concept of roads and rubber tires?


  • Early EVs and horse carriers had large wheels because the roads and paths where dirt or cobblestone.

    My point is that, if they had simply said “okay, that is the condition that we need to accept, adapt to and solve” like we do today with tarmac roads taking for granted, they could have developed a vehicle to do that. It would probably have larger wheels and soft suspension, but the only reason cars are shaped as they are today is because they didn’t solve it back then.

    What happened instead was that low torque combustible engines were subsidized and rolled out on the condition that tarmac roads were also provided by the state. This was largely due to bitumen being a biproduct from petrol production. The oil industry pushed for both combustible engines and tarmac because they could supply both.

    My previous rant is basically just entertaining the idea of what we’d do today if posed with a similar challenge. Roads are absolutely taken for granted and tmwe will never be able to undo that. It might be relevant if we ever inhabit another planet, but the last I read was that road planning had already begun on the moon…




  • Yeah tires is probably one of the worst inventions ever. It spreads microplastics everywhere. The main purpose is traction.

    Tarmac is bad too. Roads as a whole is a pretty bad solution.

    It’s almost as if railways had everything right from the start.

    The following is me ranting about a rather obscure theoretical idea, so please bear with me, or quit while you can.

    Now, if we were to reinvent the entirety of transportation. Let’s imagine we rewind time to just before cars, but keep our current knowledge, are cars really the way to solve transportation? No. Just no. Imagine landing on a pristine foreign planet and the first thing we do is to pollute everything just to pave a road for transportation that also requires more pollution to use said road. It is just not right. The idea of "road’ comes from the predecessor of cars, carriages, and people sort of took that idea for granted and developed from there. I don’t even blame them.

    Let’s go back to the imaginary planet, and rethink it without the idea of “road’”. How would we solve transportation? By redesigning the wheel. In order to make a wheel that could drive over off-road, we basically need something a lot more solid and durable than rubber. And we’d need engines that could easily and swiftly apply the correct force to the drivetrain to circumvent the uneven terrain. With current technology that would be solvable.

    Guess what the first cars were? Electric and with huge solid wheels. The paved road and rubber tires are the result of a push towards combustible engines made by the oil industry. The 1800s electric car manufacturers were actually on the right path, they just didn’t have the technology or money to do it.





  • Yes, sure it can. Mashed/blended spaghetti bolognese or lasagna are available as baby food.

    Baby food products are basically just ordinary food blended and packed in smaller convenient portions. Simply look at the package to see what it contains.

    Cat and dog foods are completely different kinds of food, which is often made from animal biproducts and not suitable for human consumption.
