Abstract

Ever since H. Poincaré [1] asserted the conventional nature of the geometry of physical space, there has been a debate on this problem, particularly since a new kind of space was introduced by Einstein's General Relativity. Accounts and bibliographies were given by many authors, among which we cite A. Griinbaum [2] and J. Ehlers [3].
