If we wanted to use the definition of isomorphism to prove that Z is not isomorphic to Q, we would have to show that there does not exist an isomorphism p : Z Q. In other words, we would have to show that every function that we could possibly define from Z to Qwould violate at least one of the conditions that define isomorphisms. To show this directly seems daunting, if not impossible....
