Ed's guest is Felix Palmer, introducing the A5 discrete global grid system. The conversation explores the intriguing concept of tiling pentagons, revealing that while it may seem impossible, it can be achieved by altering the angles of the vertices. The discussion also delves into the implications of projections from geometric shapes like the icosahedron to the sphere, highlighting how these projections can warp angles yet still maintain surface coverage.Show notes on the Geomob website, where you can also learn more about Geomob events and sign up for our monthly newsletter.
