How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension

@ErikReaganRefresh Savannah

“Geographical curves are so involved in their detail that their lengths

are often infinite or, rather, undefinable. However, many are statistically "self-

similar," meaning that each portion can be considered a reduced-scale image of

the whole. In that case, the degree of complication can be described by a quantity

D that has many properties of a "dimension," though it is fractional; that is, it

exceeds the value unity associated with the ordinary, rectifiable, curves.”

Fudge Ratio

1. Start guestimating things

2. Write down your guestimate

3. Do

4. Write down the actual time spent

5. Calculate your "fudge ratio"
