Les ZFleurs des Mathématiques


An attractive and intriguing image by Kristina Armitage for an article on Zermelo-Fraenkel set theory at Quanta Magazine (click for larger image).


Post-Performative Post-Scriptum

The title of this post is a pun on Charles Baudelaire’s Les Fleurs du mal / Flowers of Evil (1857). If you’re already familiar with the book, you might have missed the “ZF” of ZFleurs.

The Bird Dimension

M.C. Escher, Another World / Andere Wereld (1947)


This is almost my favorite image by Escher. But I’d like a frEscher perspective in it: I think the bird should be looking in the other direction, out into the impossibly overlapping universes, not into the cupola and at the viewer.

Bennae Bellae

Feathers by Ben Rothery (click for larger)


Post-Performative Post-Scriptum

“Bennae Bellae” is a play on Pennae Bellae, which is Latin for “Beautiful Feathers” (Pennae Pulchrae would be better, but not as assonant).

Ho Rhodornix

Y Rhosyn a’r Wylan

There’s a rose at Number Seven,
Tho’ the air is wintered now,
And it glows at Number Seven,
In the brain behind thy brow.

There’s a gull that turns the stillness
Of the air above thy head:
’Tis the gull that spurns the illness
Of the creed where color’s dead.

There’s a rose at Number Seven;
There’s a gull that turns the air:
And what glows at Number Seven
Is the spurner turning there.
