Episode notes

After Johannes Kepler's discovery of his famous three laws of planetary motion, there were meant to be improvements on Nicholas Copernicus's heliocentric model. It was during this time that many of the foundational ideas of our civilization were codified. Knowledge is basically a special kind of information that, once instantiated in the world, tends to cause itself to remain so. This definition emerges naturally in our deepest theory in physics, which is called Constructor Theory.

In this episode of Fallible Animals, we discuss how it is that sciences progresses, despite the fact that all science is conjectural. It turns out that progress entails reducing errors in our worldview. We define knowledge and review its growth over the course of history. Finally, we take as a case study our ever-improving understanding of our own Solar System, from Copernicus to Kepler to Newton.
