Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest.
There are now nearly 700 maps.
I believe the gap in know how is related to learning -- new learning, unlearning, relearning.
I think of knowing as a more staid, steady, stable state. When I know something, it is for sure; it is so sure it is fact.
Learning is an active state, an process of searching, digging, questioning, connecting, thinking, imagining, visualizing, trying, pitching, collecting, building, sharing, enhancing, coloring, synthesizing, communicating. Learning is unfinished.
