Her lips are pips
I call her hips
“Twirly” and “Whirly.” 

Song lyric

(Pips are the dots on dice. The above "choose us" image in the form of a
St. Bridget's cross is from Twirly Industries, a sportswear maker in Pakistan.)

Techie Wordplay: “Lynx”

On the  Lynx  web browser

"As of 2022, it is the oldest web browser still being maintained,,,,"

"The speed benefits of text-only browsing are most apparent
when using low bandwidth internet connections, or older computer
hardware that may be slow to render image-heavy content."
— Wikipedia [“Older” link added.]

And then there is . . .

See as well the LYNX of Oslo artist Josefine Lyche.

Update of June 30, 2022 —

Lyche, whose art often incorporates mathematical notions,
has not yet, as far as I know, explored the Borromean  link
(three rings, linked mutually but not pairwise) in her art.

Remarks by a different math fan, Evelyn Lamb

"I have had a thing for the Borromean rings for years now.
There’s something so poetic about them. The three rings
are strong together, but they fall apart if any one of them
is removed. Alternatively, the three rings are trapped together
until one of them leaves and sets the others free. I’m kind of
surprised there isn’t a WisÅ‚awa Szymborska poem or 
Tom Stoppard play that explores the metaphorical possibilities
in the Borromean rings." — Scientific American , Sept. 30, 2016.

at a round table or a square one?"

Disturbing Archimedes

Filed under: General — Tags: — m759 @ 2:01 pm

Princeton University Press on a book it will publish in March—

Circles Disturbed: The Interplay of
Mathematics and Narrative

"… brings together important thinkers in mathematics,
history, and philosophy to explore the relationship
between mathematics and narrative.
  The book's title recalls the last words of the great
Greek mathematician Archimedes before he was
slain by a Roman soldier— 'Don't disturb my circles' …."

Tesseract

"… a finite set with  elements
is sometimes called an n-set …."

Tesseract formed from a 4-set—

IMAGE- Tesseract.


The same 16 subsets or points can
be arranged in a 4×4 array that has,
when the array's opposite edges are
joined together, the same adjacencies
as those of the above tesseract.

"There is  such a thing as a 4-set."
— Saying adapted from a novel
