You can easily count all the reals on the real number line now. In fact, you can count all the
"points" in any dimension as well. I will not show as I don't see the point anymore.
There's one last thing about the power set of the set of all integers being uncountable. This
proof also uses a diag. fn approach. You can prove it incorrect (use that special case I
mentioned when I was pointing out the flaws of the diag. fn, where I created a list only using 0
and 1). I can show you how the counting works as well. It's easy. But I'm not going to since I
have a problem with the definition of set and thereby the concept of power set.
The article concludes here. Thank you for going along this crazy journey with me.
