    I think the statement “this system is consistent” is a practical statement that is unprovable in a sufficiently powerful consistent system.

    Can you help me understand the tone of your text? To me it sounds kinda hostile as if what you said is some kind of gotcha.

    It’s very counter intuitive. As the other commenter suggested I was referring to Gödel and his incompleteness theorem.

    Actually if the system you made up doesn’t work it would be possible to prove that it does inside that system as you can prove anything inside a system that doesn’t work.

    That is why my comment is not entirely accurate it should actually be: Until you prove that if the system works you can’t prove that the system works.

    Can you spot the difference in the logic here?




  • I’m actually quite interested in dress history. I’m an engineer at heart and clothing is fundamentally also an engineering problem (and design of course). It’s an area of engineering that was always dominated by women and you can sometimes see the novel approaches that brings.

    For example historical corsets were actually quite comfortable when fitted right. One reason why is actually breast support. Predecessors to the modern Bra did exist but were not in fashion as a more compressed looking bust and later a shaped silhouette was in fashion.

    Also it’s cool what tricks one can use to form the silhouette without extremely compressing the waist (which is how many modern people often think is the function of a corset).

    I recommend Bernadettes channel on this topic: link

    If you only think about half live then yes it would be radioactive forever but in reality after a long time every atom would’ve decayed into non radioactive elements.

    You can even calculate the expected time it would take for the random process of decay to terminate.











  • I do not like Orban at all and hate to agree with him, but I think he is right. I think there are two big reasons why Ukraine is unlikely to join the EU proper in the near to medium term:

    1. The EU needs reform when it comes to deciding things when there is no consensus and this is now a very accepted position.The EU will only become more sluggish if we open the gates to another country with veto power.
    2. Farmers. Ukraine is a big (and has potential to be even bigger) aggreculture powerhouse. Many laws (aggreculture subsidies etc) in the EU are not sustainable if Ukrain becomes part of the EU.

    These problems are solvable, but take a lot of time I think. Also I don’t think it is in the EUs best interest to allow a war torn/rebuilding market into the single market, but here I could be wrong. Maybe there are reasons (like a way to exploit Ukraine after the war) that would invalidate my theory…

    I would like to see the EU expand, but I think it will take a long time.



  • This sounds fascinating. I was always fascinated how complicated life could be in days past. Like how we take decimalization for granted today or the cheap conversion of money and the enormous availability of modern currency (i.e. Paper money and coins).

    I once read about coin shortages and how that could impact an entire region. Fascinating stuff.

    Do you happen to have book recommendations on the topic of coins or economic history of Europe (or even more specifically the German speaking area)?
