Dear Sung et al., I appreciate human bias in terms of numerical scale, but I don’t think that is what we actually achieve by using logarithms. If the universe of possibility is fractal, using a logarithm does not eliminate the problem of large numbers. I think the primary outcome achieved by using logarithms is that units come to represent proportions rather than absolute (fixed scale) amounts. It reveals an aspect of scale-free form.
