Charles and Ray Eames were thinking about scale and using the system of exponential powers to visualize and understand large quantities long before their magnum opus of 1977, *Powers of Ten: A Film Dealing with the Relative Size of Things in the Universe, and the Effect of Adding Another Zero *(the title says it all: the magic lies in it’s brilliant demonstration of one example). Their films *A Communications Primer,* 1953 (based on Claude Shannon’s *The Mathematical Theory of Communication*, 1949), and *2 ^{n}* from 1961, are examples of this kind of thinking. Kees Boeke’s book

*Cosmic View: The Universe in 40 Jumps*,1957, provided a framework for the explorations of scale seen in

*Powers of Ten: A Rough Sketch for a Proposed Film Dealing with the Powers of Ten and The Relative Size of the Universe*, 1968, and

*Powers of Ten…,*1977.
