Tom Wujec: Learn to use the 13th-century astrolabe

The video explores the impact of technological progress, using the astrolabe as a case study. It discusses how the astrolabe, a 13th-century device, was used to tell time and understand the sky. The video explains the concept of stereographic projection and provides a step-by-step guide on using an astrolabe. It highlights the device's historical significance, various uses, and its role in connecting people to the universe. The video concludes by reflecting on the astrolabe's legacy and the balance between technological precision and a felt sense of the world.
