To me, the new URL "Songlines.space" suggests both the Outback
and the University of Western Australia. For the former, see
"'Max Barry' + Lexicon" in this journal. For the latter, see SymOmega.
The new URL forwards to a combination of these posts.
Three properties of space — interlocking, interlacing, interweaving.

— "Socrates, the fourth, intertwining, is at . . .

(The "intertwining" part is at Sex Textiles (March 26, 2021).)
Another concept from The New York Times today: intertwining —
“The historical achievements and experiences of women and men
are like the intertwined warp and weft threads of a woven fabric.”
— Virginia Postrel in a NY Times opinion piece today.

Actually, Dirac “bridged math and physics” much earlier —
“Spinors, which are a kind of square root of vectors, had been introduced
in algebra and also in physics as part of Paul Dirac’s theory of the electron.
A spin structure on a manifold allows such square roots to exist.”

Poetic paraphrase —
“How can we tell the singer from the song?”
Fiction set in Duke Humfrey's Reading Room at
the Bodleian Library, University of Oxford:

"I walked quickly through the original, fifteenth-century part of the library, past the rows of Elizabethan reading desks with their three ascending bookshelves and scarred writing surfaces. Between them, Gothic windows directed the reader’s attention up to the coffered ceilings, where bright paint and gilding picked out the details of the university’s crest of three crowns and open book and where its motto, 'God is my illumination,' was proclaimed repeatedly from on high."

The reader may contrast the above Squarespace.com logo

for a square space (the Galois window ):
(Continued from November 13)
The work of Ron Shaw in this area, ca. 1994-1995, does not
display explicitly the correspondence between anticommutativity
in the set of Dirac matrices and skewness in a line complex of
PG(3,2), the projective 3-space over the 2-element Galois field.
Here is an explicit picture —

See my post of Nov. 23 on publications by E. M. Bruins
in 1949 and 1959 on Dirac matrices and line geometry,
and on another author who gives some historical background
going back to Eddington.

finite geometry and quantum theory —
The matrices underlying the Saniga paper are those of Pauli, not
those of Dirac, but these two sorts of matrices are closely related.
