A Japanese web magazine investigates the proportions behind sunflowers, A4 paper, television screens, and other familiar objects.

Landing page captured for the 2026-09-12 issue.

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.
