Hilbert's First Problem and the number four
Hilbert's First Problem was about the continuum hypothesis,
so really about: is the arithmetic of infinite numbers
simple? What are its rules? The talk will be exclusively
in naive set theory, and does not assume any specialized knowledge.
We try to exemplify the idea, that when we ask the right question
there is much to be said, even restricting ourselves to sets of reals only.
