Designing experiments is hard. It is difficult to create something that is both simple enough to understand fully AND useful at the same time. For this reason, I am particularly impressed with a paper by Hunter and Weeks; it is creative and elegant.
They simulate three discs in a circular container and measure the free energy landscape of the system (something that is often too abstract to visualize or to be of any practical use). Their paper has influenced the way I approach problems, so I figured I’d share their paper with you!
