How Did We Get Here?: Planet
In this installment of “How Did We Get Here?”, we considered the intellectual history of “planet” with mathematician, physicist, and astrophysicist Kelly Cline. We started with the ancient Greeks, moved to Copernicus, and then sashayed into the 20th century. Along the way we learned about how scientific words and their definitions serve as a specific lens through which we can view the world. By scientifically defining words so that they most closely match real categories that exist in physical reality, this makes it easier for us to understand, investigate, and make sense of the universe. As such, this installment of HDWGH and the evolution of how we understand and use the word planet gave us important insights into the nature of science and the foundations of our modern civilization.
