We spend a lot of time working with our hands, in fact that’s why we can do science at all. It’s shocking the amount of science ignorance and lack of skill floating around. This got us wondering we are bad at science and where the practical skills we have are going. Then we found some articles!

Maps are useful things, but it turns out that projecting a 3D object on a 2D map can cause a lot of unexpected problems. They even inspired an XKCD comic. This week we explore maps and map projections. We also chat about machine learning as part of #FunPaperFriday. What’s the big problem? The Earth is a sphere, actually it’s an ellipsoid, actually it’s really bumpy and messy Taking 3D information and pushing in onto a 2D medium means that you must sacrifice something, you are losing a dimension
