The Continuum Hypothesis:
A Look at the History of the Real Numbers in The Second Millennium.


Abstract:

After Cantor first demonstrated that the real numbers (continuum) were uncountable, the hypothesis arose that the set of the real numbers was "the smallest" uncountable set. In 1900 David Hilbert made settling the continuum hypothesis the first problem on his now famous list of problems for this century. The author will discuss some of the historical, philosophical, and mathematical  developments connected to this problem proceeding from issues of definition of the real numbers and proofs of uncountability to issues of consistency and models and proofs of the independence of this hypothesis and possibly some comments on its current status.
