I suddenly remembered my college days where one of my classmates present a research paper, one of the teacher says it's already been used by previous student last year. And the other prof said that why it name as "re-search" to continuesly present innovative over the same topic that have been used.
Which also answered in your statement
discussion and the increase in understanding.
lol - exactly :)
re-search is the scientific method and every great idea, had humble beginnings through many mediocre ideas.
