In Memory of Ernst Eduard Kummer

Filed under: General — Tags: , , — m759 @ 3:33 pm

(29 January 1810 – 14 May 1893)

See as well some earlier references to diamond signs here .

The proper context for some diamond figures that I  am interested in
is the 4×4 array that appears, notably, in Hudson's 1905 classic 
Kummer's Quartic Surface . Hence this post's "Kummerhenge" tag,
suggested also by some monumental stonework at Tufte's site.

The diamond signs of Donald Knuth

“When there’s nothing to believe in 
Still you’re coming back,
you’re running back 
You’re coming back for more
 
So put me on a highway….”
— Eagles, 1975

The Meaning of 3:16

From The New Yorker, issue dated Feb. 28, 2005:

"Time Bandits," by Jim Holt, pages 80-85:

"Wittgenstein once averred that 'there can never be surprises in logic.'"

"Miss Gould," by David Remnick, pages 34-35:

"She was a fiend for problems of sequence and logic…. Her effect on a piece of writing could be like that of a master tailor on a suit; what had once seemed slovenly and overwrought was suddenly trig and handsome."

Suddenly:

See Donald E. Knuth's Diamond Signs, Knuth's 3:16 Bible Texts Illuminated, and the entry of 3:16 PM today.

Trig and handsome:

"She shaped the language of the magazine, always striving for a kind of Euclidean clarity– transparent, precise, muscular."

Intersecting altitudes
Einstein on Time cover

Einstein on his
"holy geometry book" —

"Here were assertions, as for example the intersection of the three altitudes of a triangle in one point, which– though by no means evident– could nevertheless be proved with such certainty that any doubt appeared to be out of the question. This lucidity and certainty made an indescribable impression upon me."
