Fortunately, they'll never happen. How are you supposed to get your connecting regional train if it doesn't stop at the same station? And it's often a huge advantage of rail that your journey starts and ends near the city center.
I once wrote a brainfuck interpreter in Haskell which executes even incomplete programs as far as possible. It was really easy thanks to streaming ByteStrings and lazyness in general.
I'm somehow afraid of a world in which huge amounts of energy can be wasted without having a bad conscience. Probably it would lead to some new problems.
What if the world is just a dream? Then an individual person's consciousness has a massive influence on the weather. And there would be new arguments for the existence of God.
All formulas and statements are expressed in first-order logic. It has no such phrase as "pick". But picking (in the axiom of choice) means: Finding a function that maps every set to an element of this set.
What is a function: It's a set of tuples where every tuple (x, y) means: x is mapped to y. Of course there must be exactly one tuple for every "x".
(Tuples btw are usually a short notion for {{x}, {x,y}}. They exist always by the axiom of pairing. By the axiom of extensionalty, they fulfill the universal property of pairs, i.e. (x, y) = (z, w) iff x = z and y = w.)
Assume x is a single nonempty set. Picking means: Finding a function {x} -> x. But this is easy: ∃y(yϵx) because x is nonempty, and then we can build our function, which consists just of the single tuple (x, y).
It also works for finite sets of sets since you can do it manually n times, the formula just gets longer.
Merkel grew up in a country where you could be "banned" for anything. I'm not surprised that she doesn't like the idea of private companies deciding according to their own (not democraticly chosen) rules who should speak and who shouldn't.
Bad handwriting causes data loss since 5000 years probably. Whether it's an AI or a human reading it, handwriting is sometimes impossible to decipher. To avoid data loss, don't use handwriting or write very neat.
I for one liked it.
