After Simon read up on spherical geometry on Brilliant.org, he and Neva crafted some pretty colourful half-spheres. How’s that as an alternative to Easter eggs? Simon has also discovered a great tutorial on spherical geometry by Think Twice: Spherical Geometry: Deriving The Formula For The Area Of A Spherical Triangle. Think Twice is an awesome resource for animated math, helping to understand mathematical concepts intuitively through visualising them (accompanied by beautiful music that Simon sometimes just turns on simply to have some math and music beauty on the background).
They also had fun looking for shortest routes across the Atlantic applying their knowledge of geodesics.
Simon had already recorded a video about how to make such a sphere, see our earlier publication here.
