Episode notes

Infinity is not a number in the usual sense, and so there are things you can say about infinity. This was one of the discoveries by Georg Contour years ago that there are different sizes of infinity in the set of real numbers. A subset of the integers may or may not be infinite in size, but if it is finite in size, it is equal in cardinality to the integer as a whole.

Welcome to the June 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic. Enjoy!
