    "Independen Day: Resurgence" is on TV now. It has the old actors and a bunch of important others. However, reviews say it's very bad. The first one, watched as a kid, caused a huge impact on me.

    [1/4] “Frame dragging” by a rotating black hole is a very cool phenomenon — and less arcane than it’s often portrayed to be. Suppose you woke up in some kind of space habitat, with a dome that showed you a sky full of stars that remained perfectly still. You feel 1 gee’s weight.

    The vast majority of numbers in the universe are non computable, but fortunately for us, the universe seems to only need computable numbers. Why? A mystery.

    -> you can create a function that does what Cantor did in his diagonal argument, so then the number of functions is non countable.

    I think this is equivalent to saying that the number of computer programs is countably infinite. The number of functions, however, is uncountable infinite, because ->

    Indeed, since the first time I saw the ranking of universities, I'm surprised by how far European (non UK) universities are in the ranking. (I'm sadly not surprised by the position of Spanish universities).

    Books like "The 7 habits of highly effective people" and similar (on managing your time, optimizing...) Do they really teach something valuable or nothing you can't learn by common sense?

    A strong argument in favor of the EU: it is attacked by both sides of the political spectrum => high probability of being the correct way.
