Ring, field, injection, surjection, bijection, jet, bundle. Does anybody know who first introduced those terms and when and why those people called these matimatical structures so. I mean not the definitions but the properties of real things which can be accosiated with those mathematical structures terms. For example, 'nutural number' is number which can be associate with the real things in the nuture, e.g. 1,2,3.... Number 0 is not nutural, because nobody see zero thing, and the negative number too.
