\section{Euclidean and Non-Euclidean Continuum} THE SURFACE of a marble table is spread out in front of me. I can get from any one point on this table to any other point by passing continuously from one point to a ``neighbouring'' one, and repeating this process a (large) number of times, or, in other words, by going from point to point without executing jumps. I am sure the reader will appreciate with sufficient clearness, what I mean here by ``neighbouring'' and by ``jumps'' (if he is not too pedantic). We express this property of the surface by describing the latter as a continuum.
