All of our fancy radio and electronic equipment depends on detailed knowledge of the behavior of matter at the smallest of scales. Here is where ICs acquire their characteristics and where memories are stored. At this scale, quantum mechanics takes over! This week's puzzle shrinks its focus down to the level where the world is mostly empty space--the atomic--so your pencil will have to be mighty sharp.
