it leads to the idea that measuring 2 sets via a bijection is a better idea than measuring via containment
- andrewla 1y agoThat a bijection exists is incredibly useful. But the idea of "measuring" infinite sets in the cardinality sense is not very interesting or useful.
- oskaralund 1y agoSaying that two sets have the same cardinality is equivalent to saying there is a bijection between them. I don't understand how the latter can be useful but not the former?
