Erik-Jon Gaizka, the magician of infinity

摘要

A favourite trick for any magician is to come out on stage wearing a top hat,nremove it and show it to the audience to persuade everyone there’s nothingninside. Then he places the hat on a table, in full view of the audience, but justnfar enough away so that no one can see inside it. All that’s left is for him tonpronounce the magic words and ... hey presto! the magician walks up to thenhat, from which, with no apparent effort, he then pulls a sleek white rabbitnbefore the breathless spectators. Of course, there’s a trick to it: in a world likenours such a thing is not physically possible. What I would like to show in thisnarticle is that, in a world that only differs essentially from ours in the fact thatnin it we can take advantage of the peculiarities of infinity, it is really possiblento make a rabbit appear from a top hat, with no trick whatsoever.
