Query: Some mathematical properties of the Bartlett chi ratio   Based on artistic interpretations, art professor Christopher Bartlett (Towson
University, USA) suggested introducing a new mathematical constant related to
the golden ratio. He called it the chi ratio, as chi follows phi in the Greek
alphabet. Without going too much into the artistic considerations, which may be
subject to criticism similar to the golden ratio debunking, we focus on showing
that the chi ratio is interesting as a number as such, with remarkable
geometric properties, just as the golden ratio is.
