comment Proving the uncountability of $[a,b]$ and $(a,b)$
I just realized one thing.If we use the Schroder-Bernstein theorem,which I studied just now, and we use the fact that $(a,b)$ is an injection into $[a,b]$ and $[a,b]$ is an injection into $(a,b)$.That way, there is a bijection between $[a,b]$ and $(a,b)$.
