Welcome to 2020. This year has special significance for me, as my oldest son will graduate high school and prepare to go off to college in the fall. Like many high school seniors, he is uncertain about what he wants to do in life; but he is excited and confident that the next few years will bring great things.
2020 is an interesting year numerically as well. Not only does it begin a whole new decade, but it brings to mind the concept of perfect vision as well as one of reflection — hindsight is, after all, 20/20. In this issue of SDM, both meanings are explored in various ways.
