Trajectories
At the Galileo Museum, it was fascinating to learn about the original uses of different tools available at the time. The telescope was originally advertised for navigation and military purposes before it was pointed towards the heavens. In addition, compasses (the mathematical compass not the directional compass) were used to calculate distances and angles for navigation and trajectories. I enjoyed learning about how it was discovered that artillery followed a parabolic path. Because of this discovery, compasses were used to calculate the distance and angle required to hit the opposing forces.

I liked how Galileo after upgrading and redoing the telescope, first sold the telescope to different militaries as a way to get the word out on the telescope and to pay for the work he had done.
