Lessons from the Landscape

I will discuss how the string landscape might inform how we think about low energy effective field theories coupled to gravity. By studying the largest-to-date ensembles of geometries for string compactifications, we find several striking generic features: large hidden gauge sectors, regions of strong coupling, and large numbers of light axions. Understanding these ensembles, and the landscape as whole, requires a new set of tools, both formal and computational, including new mathematics and tools from data science, the development of which I will discuss.
