This isn’t a substitute for books . Reminder $A \preceq B$: $A$ can be “injected” into $B$. $A \sim B$: $A$ and $B$ share the same cardinality. $A \prec B$: $A$ can be “injected” into $B$, but it’s “smaller” than $B$. A finite set can be “counted” from one to some nonnegative integer. Infinite is the “antonym” of finite. Wolf’s proof When I first saw this proof in Robert S. [Read More]
