A professor once said to me: publication is about intelligent copy paste from one field to another. His claims were right in a sense that he knew what results already exist in one field and apply it to the other non-mature yet field. Ofcourse he didn't mean a literal copying.
If you are working in a cut-edge research (a new obscure area) and already familiar with another stable mature-enough area, is utilizing one's techniques to the other is a good approach for making contributions to the field?
is it count as a good contribution?
is it common in Academia? (specifically for Computer Science field)
