Overall: 
No problems with the article, pic is nice, and the hook is interesting enough for a broad audience. Karma points for double QPQ. –LordPeterII (talk) 14:18, 14 September 2022 (UTC)
- Hi there, David Eppstein, could you point me to the verifying quote in the book? theleekycauldron (talk • contribs) (she/her) 23:16, 10 October 2022 (UTC)
- It's a magazine, not a book. Pp. 454–455: "The inner yellow portion of a daisy exhibits a beautiful geometrical arrangement of its elements ... the configuration of the flower (Fig.5)". Of course he doesn't call it a Doyle spiral or a circle packing (that would be anachronistic and impossible for a hook about how those concepts were used much earlier than they were named) but Fig.5 (the one reproduced in the hook image) is a Doyle spiral. —David Eppstein (talk) 23:42, 10 October 2022 (UTC)
