New thoughts on QFT formulation by Nima Arkani-Hamed. Citing from the talk: "What's as a misnomer called gauge symmetry, whose beauty is extolled at length in all the textbooks on the subject, is completely garbage. It's completely content free, there's nothing to it." Newer thoughts on QFT formulation: Amplituhedron (Wiki) - locality and unitarity are also not fundamental |
