May 9, 2011 at 1:46 | comment | added | Michael Hardy | I think it's better not to phrase it as a proof by contradiction. Instead of saying "Suppose there is a bijection", say "Consider any injection", and then show that it misses some points. | |

May 8, 2011 at 7:24 | comment | added | Asaf Karagila♦ | If you try to impress them in the largeness of a "bigger cardinality" just try and give them the idea how far from $\aleph_0$ is $\aleph_1$, that no matter how far you went - if you only walked a countable number of steps from $\omega$ then you are still countable. This is a stepping stone in understanding how big is the difference in cardinalities, from here explain vaguely that the power set can be almost anything larger, so it must be vastly larger. | |
