I’m pretty sure he was involved with the liberation theology movements in Argentina before the previous pope clamped down on it (in his capacity as a cardinal)

I’m not sure late unification is necessarily the determing factor here. e.g. look at Italy

you can model the tax on the supply or the demand. in most simple models the outcome is the same

technically yes, but to proof would usually show that this works by constructing the bijection of [0,1] into (0,1) and then you’d say the cardinalities are the same by the Schröder-Berstein theorem, because the proof of that is likely not something you want to demonstrate every day

even if that’s not how you can write it, one gets the same issue in yours subtracting infinity from both sides

it’s actually Vulcan

ah, but don’t forget to prove that the cardinality of [0,1] is that same as that of (0,1) on the way!

no, there aren’t enough integers to map onto the interval (0,1).

probably the most famous proof for this is Cantor’s diagonalisation argument. though as it usually shows how the cardinality of the naturals is small than this interval, you’ll also need to prove that the cardinality of the integers is the same as that of the naturals too (which is usually seen when you go about constructing the set of integers to begin with)
