A common challenge in computational science is addressing multi-scale phenomena: large-scale environments influence small-scale behaviors, which in turn affect the larger system through complex feedback mechanisms. For instance, in galaxy formation, gas accreting into galactic centers powers an active galactic nucleus, resulting in significant reduction of star formation throughout the host galaxy over hundreds of millions of years. Similar multi-scale dynamics are present in climate models, where local phenomena impact global behavior, as well as in numerous other scientific and engineering fields. I am involved with Leibniz-Campus SCALES, an initiative that unites scientists modeling these phenomena in astrophysics, climate science, earth system modeling, and mathematicians focused on the underlying methodologies. Our goal is to learn from advances across these traditionally separate disciplines and collaboratively enhance the reliability and accuracy of our models by leveraging our broad, collective expertise.
