Sagan then directs our attention to a less complicated topic than our quest for knowledge of the Universe; when he asks "Can we know... in detail a grain of salt?" We all know what a grain of salt is; or do we? When Sagan discusses the atomic composition of a grain of salt and its "1016 sodium and chlorine atoms," molecular composition. The ability of science to provide all the knowledge in the universe became a sad reality, when Sagan drew our attention to the fact that “the total number of things knowable by the brain is not more than 1014…, but this number is only 1 % of the number of atoms in our grain of salt.
