An Educational Satellite Explorer—Built with AI
How we built a single-file, offline satellite visualization app with AI. The method: Define a role for the AI, plan-then-proceed, and use evidence (show images, don’t just tell) to drive development. We built a single-file, offline web app that visualizes two satellites and a ground station. It displays everything on a 2D map and a […]
Tidal Acceleration
An example of tidal acceleration discussed in General Relativity. It shows a ring of particles free falling in a non-uniform gravitational field. Specifically 5 gram dice falling toward a 1000 kg “bowling ball”, time is speed up. The program Universe Sandbox was used in creating this simulation. General Relativity. A few short lectures by Avi Rabinowitz, […]
