Emma Willard's Maps of Time

Maps have long been a part of human society. They are valuable tools to pass on knowledge. Still, in using maps, abstractions, and models, we must always be wise to their limitations. They are, by definition, reductions of something far more complex. There is always at least an element of subjectivity, and we need to remember that they are created

A map, compared with text, makes it easier to see and understand how a complex system fits together. It also has the potential to show roadblocks, dead ends, and relationships in a way that brings the big picture to life.
