Title:  Physics We Learned with the Event Horizon Telescope 

Abstract: The Event Horizon Telescope has allowed us to obtain direct images of two black holes, the one in the center of the M87 galaxy and the one in the center of the Milky Way, with horizon-scale resolution, full polarization, and timing information. In my talk, I will discuss how we have used these observations to get new insights into the microphysics of plasmas in strong gravitational fields, the mode of accretion onto supermassive black holes, the properties of turbulence in the interstellar medium, and the intricacies of black-hole spacetimes near their horizons.
