• ... that binary logarithms can be used to determine the number of octaves between two musical tones and the number of stops between two photographic exposures?

Improved to Good Article status by David Eppstein (talk). Self-nominated at 00:24, 30 December 2015 (UTC).

• Recently promoted to Good Article, long enough, within policy. QPQ done. Hook interesting, first part cited, but I could not find any content or reference to finding the number of stops between two exposures. Suggest shorter hook:

ALT1: ... that binary logarithms can be used to determine the number of octaves between two musical tones?

The hook source is on the sentence "A single stop of exposure is one unit on a base-2 logarithmic scale." But ALT1 is ok with me. —David Eppstein (talk) 19:10, 31 December 2015 (UTC)

• Good to go with ALT1. Zeete (talk) 19:18, 31 December 2015 (UTC)
