Bertram Kostant, Professor Emeritus of Mathematics at MIT, on an object discussed in this week's New Yorker:
Hermann Weyl on the hard core of objectivity:
relevant feature of modern science is the emergence of abstract
symbolic structures as the hard core of objectivity behind-- as
Eddington puts it-- the colorful tale of the subjective storyteller
mind." (Philosophy of Mathematics and Natural Science, Princeton, 1949, p. 237)
Steven H. Cullinane on the symmetries of a 4x4 array of points:
|
A Structure-Endowed Entity
"A guiding principle in modern mathematics is this lesson: Whenever you -- Hermann Weyl in Symmetry Let us apply Weyl's lesson to the following "structure-endowed entity."
What is the order of the resulting group of automorphisms? |
automorphisms plays
a role in what Weyl,
following Eddington,
called a "colorful tale"--
The Diamond 16 Puzzle
This puzzle shows
that the 4x4 array can
also be viewed in
thousands of ways.
"You can make 322,560
pairs of patterns. Each
pair pictures a
different
symmetry of the underlying
16-point space."
