Abstract: Gauge theories provide a highly successful framework for the description of nature, even though precision calculations tend to become enormously complex. This complexity may not be a feature of gauge theory itself but of our computational schemes. In conventionalFeynman graph expansions, for example, one often observes unexpected cancellations which can result from hidden symmetries. Where such hidden symmetries of gauge theory have been uncovered, they turned out to be well known from a seemingly unrelated area of physics: the study of solvable 1-dimensional quantum system. In my talk I will review some of these intriguing connections, and I will illustrate their powerful implications at the example of high energy scattering amplitudes.
