Fig. 7: Modeling the curvature of the hybrid crystals to logarithmic and Archimedean functions.
From: Logarithmic and Archimedean organic crystalline spirals
a A typical Archimedean spiral with red dots representing the constant distance between the adjacent intersections. b A typical logarithmic spiral with red dots representing logarithmic increase between every intersection along the x axis. c The Archimedean function that best fits the P4//2j crystal. d The logarithmic function that best fits the P4//2e crystal.
