When I was a child I took this book down from my fathers bookshelf and looked at the illustrations for long spells. The style was intriguing. I puzzled out the meanings of the pictures long before I could read or understand the text and the ideas of the history of mathematical ideas. But I got the gist of things through the illustrations. Over the years the book was lost from my father’s collection. But I found the scanned text online and finally got around to making a copy for my own digital files. The video puts things in a continuous display. I will put the video on Youtube and use whatever copyright free music Youtube offers. I looked up the book online a few years ago and saw that I could by a copy from 1956 for maybe $60. But it is online free….

I think of sitting on a hardwood floor near the window next to the dinning room table as sunlight came through the lace curtains. I can picture myself being about ten years old. I liked the historical graphic approach to the idea of mathematics the book displayed. In school math just seemed like blackboards and white chalk and problems and boredom. I was always looking out the window. Kinda like this….

This picture gave me a visual map of the river of time. I thought the past seemed a lot more exciting than the hum drum present I lived in.

And…I uploaded the video to Youtube and got an audio track that I did not hear because the computer I’m video editing on does not have audio. So, I picked a Youtube supplied ambient music track and than go to my laptop to see what my video sounds like. Not bad.
