Field notes
The publication sorts its material into three visible categories: golden-ratio cases, alternative proportions that serve as practical optima, and claims that do not survive checking. Its current examples connect 137.5° sunflower-seed spacing with packing, 16:9 screens with the compromise between cinema and 4:3 television, and 1:√2 paper with successive halving from A4 to A6. The sunflower note also cites a citizen count of 657 specimens.
