The empty set?[edit]

Perhaps Jakesyl would like to remind us how a long list of digits is more appropriate to the talk page than the following question, which the digits replaced. —Tamfang (talk) 06:52, 15 July 2014 (UTC)

Isn't there something in the article about other symbols that resemble phi? —Tamfang (talk) 09:30, 12 July 2014 (UTC)
Well, good this is here. Otherwise, I wouldn't believe that people could confuse those symbols... — LlywelynII 04:16, 6 October 2014 (UTC)

Grain Size[edit]

Phi is a symbol used when describing grain size in sedimentology. Wentworth and Krumbian scales both use φ to describe the size of individual sediment particles.

This should be added to the list of scientific measurements that utilize phi.
