Chapters 7, 9, and 11 refer to supplemental animations. They are gathered together on this page. If your browser is unable to play these directly, you’ll need to download them (try right-clicking on the file links).
Chapter 7: Diagrams and Animations
Here is an animation of an orbit with epicycles made using Javis: 395k MP4 video.
This is a short video of a vibrational mode of a drum head, assembled using the Reel package: 43k MP4 video.
Chapter 9: Physics
The Oceananigans section shows how to set up a 2D simulation of thermally convecting flow. Below are links to videos of the simulation showing the temperature field, the horizontal velocity component, and the vertical velocity component.
Chapter 11: Biology
In order to gather data for the artificial evolution experiment, we ran many predator-prey simulations using the Agents package. This video shows one of them. The prey creatures are blue dots, and the predators are red or green open circles with small dot at their centers. The red predators have locked on to a target and are pursuing it; the green ones are waiting for someone to come into range.
