Galileo probably gained insight into many issues around motion from his investigation of the pendulum.
The video also mentions issues with the church and academia.
anyone else. But finally he arrived at two... three golden eggs. And the first golden egg then is that the orbits are ellipses-- he talked always about planets-- and the Sun is at one focus. That's Kepler's law number one. These are from around 1618 or so. The second... Kepler's second law is-- quite bizarre how he found that out, an amazing accomplishment.
