From QM to QFT to ST
Tomorrow, the Physics Stack Exchange should experience a silent completion of a Holy Trinity. Users are given a golden "tag" badge when the answers by a single user to questions with a particular tag reach the score 1,000.
I have just learned it has to be from at least 200 questions now. A third "tag" is waiting to join the elite club; it had the score 998 and 195 questions today. After the daily update, it should break through both thresholds, unless I am overlooking some other condition in which case I apologize for the wrong rumors in advance (update: it did happen).
For the sake of simplicity, the "tag" badges are being collected by the same user. Just to be sure, the prominent "tags" are:
quantum-mechanicsThe moment to applaud would be now! Troglodytes...
Quantum mechanics (QM) has arguably represented the most important conceptual revolution in the 20th century physics (although relativity was novel and important, too). Quantum field theory (QFT) allowed us to construct quantum theories that were compatible with Einstein's special relativity and reach the "theory of nearly everything" (TONE), using Lisa Randall's terminology, namely the Standard Model. String theory (ST) is the last step (at least so far) that allows us to add the newest insights and ingredients so that gravity and general relativity (GR) may be reconciled and some inadequacies of the whole QFT framework may be fixed.
