2. Powers of Three I first ran across the fraction 1/243 in one of the Rama series of books by Arthur C. Clarke. Now 243 is the fifth power of 3. The decimal equivalent forms a very curious pattern as I describe in the notes. I then created an Excel spreadsheet to calculate decimal equivalents of the reciprocals of different powers of three to help analyze the patterns ( the notes explain how to create this spreadsheet ). I then could extend the work to explore powers of other repeating decimals. The only limitation is the size of your spreadsheet and your imagination.

Not pure math yet, but an introduction to a method that will be mathematically described in subsequent articles.

... Let's look somewhere other than the current point a to point b method of relocation and transport. Perhaps oil is in fact the best fuel for such a method. Breaking it down, why is it we wish to go from point a to point b in the first place?...
