Introduction: 

What actually goes into a particle simulation—and why does it matter? In this accessible and engaging talk, Trevor Teague of the University of Michigan walks us through the essentials of computational particle research as practiced within COMPASS. From atomic to centimeter scales, we explore how simulations help us ask—and answer—questions that are difficult, if not impossible, to address through experimentation alone.

Combining humor, real-world case studies, and a behind-the-scenes look at cutting-edge tools, this presentation demystifies what it means to “do a simulation” and how the COMPASS team uses them to solve critical scientific challenges across materials science, energy, medicine, and beyond.
