  • A set of propositional formulas is satisfiable if and only if all finite subsets of it are satisfiable.

    The cardinality of a set is always smaller than the cardinality of the set of subsets of the former set.

    A set cannot contain itself.

    There is no 1 to 1 mapping from the natural numbers to the real numbers.

    There is a 1 to 1 mapping from the natural numbers to the rational numbers.

    Something exists. I cannot tell you what it is but it does exist. Maybe reality is an illusion but even then the illusion exists.











  • When I went on a trip to the US I bought a relatively expensive travel insurance as I knew if something would’ve happened I would be screwed forever.

    It did cost me about 80 eur but they claimed 100% cost coverage without copay or any of that nonsense. The coverage was for a whole year but only 60 days after the start of the vacation. It also included legal insurance for medical things with a max payout of 100,000 eur and medical transport back to Germany if possible and necessary.

    Did not need to use it fortunately but they advertised that they even covered stuff like decompression chambers after a dive accident. I wonder how much I would’ve needed to fight them if it came to it but I had a cheaper coverage with similar coverage from them when I went to Turkey. There I got the whole sum after I went to the hospital for a really bad insect sting without any fuzz. But it was only a hundred euros or so.

    Fortunately this is the closest near contact with the us healthcare system.
