Upcoming experiments will map galaxies and gas across unprecedented volumes and probe further back into cosmic time than ever before. These experiments have the potential to probe fundamental physics questions such as the nature of dark matter and dark energy, and the initial conditions of the Universe. But in order to extract the full scientific potential from these data, we need to understand how luminous tracers (stars and gas) are related to the underlying matter density field, and we must develop techniques that can accurately forward model the galaxy formation process with a computational efficiency that is orders of magnitude higher than standard numerical hydro/N-body techniques. I will describe the philosophy and status of the SMAUG (Simulating Multiscale Astrophysics to Understand Galaxies) project, and how it will form a pillar in the new Simons Collaboration "Learning the Universe", which will combine new galaxy formation models, new machine learning techniques, and simulation based inference to obtain constraints on cosmology and astrophysics.</span></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; -webkit-text-stroke-color: rgb(218, 215, 211); min-height: 16px;" class=""><span style="-webkit-font-kerning: none;" class=""></span><br class=""></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; -webkit-text-stroke-color: rgb(218, 215, 211);" class=""><span style="-webkit-font-kerning: none; background-color: rgb(255, 255, 255);" class="">Join Zoom Meeting</span></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; color: rgb(107, 0, 109); -webkit-text-stroke-color: rgb(218, 215, 211);" class=""><span style="text-decoration: underline; -webkit-font-kerning: none;" class=""><a href="https://uniroma1.zoom.us/j/81122901013?pwd=M1hnRHRXZkEyeW1QMFlPQ2FXa0dNZz09" class="">https://uniroma1.zoom.us/j/81122901013?pwd=M1hnRHRXZkEyeW1QMFlPQ2FXa0dNZz09</a></span></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; -webkit-text-stroke-color: rgb(218, 215, 211); min-height: 16px;" class=""><span style="-webkit-font-kerning: none;" class=""> </span><br class="webkit-block-placeholder"></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; -webkit-text-stroke-color: rgb(218, 215, 211);" class=""><span style="-webkit-font-kerning: none;" class="">ID riunione: 811 2290 1013</span></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; -webkit-text-stroke-color: rgb(218, 215, 211);" class=""><span style="-webkit-font-kerning: none;" class="">Passcode: 686688</span></div><div style="-webkit-text-stroke-width: initial; margin: 0px; font-stretch: normal; line-height: normal; -webkit-text-stroke-color: rgb(218, 215, 211);" class=""><span style="-webkit-font-kerning: none;" class="">————————————————</span></div><div class=""><span style="-webkit-font-kerning: none;" class=""><br class=""></span></div><div class="">
