{"text":"To calculate 'the' fine structure constant, 1/137, we would need a realistic model of just about everything, and this we do not have. In this talk I want to return to the old question of what it is that determines gauge couplings in general, and try to prepare the ground for a future realistic calculation.","author":"Steven Weinberg","tags":["fine-structure-constant","history-of-science","mathematics","physics","theory-of-everything"],"id":98964,"author_id":"Steven+Weinberg"}
