This question, asking about how in string theory the quanta corresponding to the different elementary particles are related to the particular excitations of only one single fundamental string, has been wrongly and brutally closed before it was even an hour old for no good reason.
It is absolutally NOT a duplicate of this question, which deals only with the general properties of quanta in quantum mechanics. Conversely, it is a very different and quite good (as one can see by the 7 upvotes (and only 1 downvote) and 4 times marked as a favorite) specific string theory question. I yesterday tried to explain this to dmckee, but it was in vain.
So can this question please be reopened, such that finally interesting answers can start to turn in (and the very stupid undeserved automatic downvote gets hopefully removed too ...) ?
