Web21 May 2008 · Gravity was once viewed as a kind of innocuous background, certainly irrelevant to quantum field theory. Today gravity plays a central role. Its existence justifies string theory! There is a saying in English: “You can’t make a silk purse out of a sow’s ear.”. In the early seventies string theory was a sow’s ear. WebSurely, Schwinger had mused, there had to be a more direct way to confront the phenomena of nature. So within a year, he did come up with a more phenomenological approach, which he dubbed source theory. Source theory papers started appearing in 1966, [ 2] first applied to electrodynamics, [ 3] and then to chiral symmetry. [ 4] couple personalized christmas ornaments
