This chapter of the book looks at the structure of our environment, including our bodies, by examining the wide spectrum of dimensions of objects. Themes discussed provide some general information about concepts of data, information, and knowledge; dimensions of objects and the ways to look on and interpret them; ways to watch events and how they depend on various factors, especially within a nano-world. These issues are further examined with reference to our bodies and microbes that used to inhabit or attack us. Discussion involves materials such as soft matter, liquid crystals, and colloids, and then events occurring as waves in the quantum world, including the very beginnings of the universe, processes going now in nature, and plans concerning Mars colonization in the near future. Further text tells about carbon in its various forms, dimensions, existing reservoirs, and its role in living organisms.
