Four-Year* Date

Filed under: Uncategorized — m759 @ 11:00 AM

"Eigenvalues. Fixed points. Stable equilibria.
Mathematicians like things that stay put.
And if they can't stay put, the objects of study
should at least repeat themselves on a regular basis. . . ."

— Barry Cipra, "A Moveable Feast," SIAM News , Jan. 14, 2006

Class of 64 continues…

Uncategorized — m759 @ 12:00 PM 

Mathematician Norbert Wiener reportedly
died on this date in 1964.

“Mathematics is too arduous and uninviting a field
to appeal to those to whom it does not give great rewards.
These rewards are of exactly the same character as
those of the artist. To see a difficult uncompromising material
take living shape and meaning is to be Pygmalion,
whether the material is stone or hard, stonelike logic."

Southwestern Noir

Uncategorized — m759 @ 2:56 PM 

Kyle Smith on April 15, 2015, in the New York Post —

"The ludicrous action thriller 'Beyond the Reach'
fails to achieve the Southwestern noir potency
of 'No Country for Old Men,' but there’s no denying
it brings to mind another Southwestern classic
about malicious pursuit: the Road Runner cartoons."

The previous post was about the death of a figure
from the world of entertainment.

but from a different world —

From the American Mathematical Society today

Jean Pedersen (1934-2016) 
Friday February 5th 2016

Jean Pedersen died January 1 at the age of 81.
She was a longtime member of the faculty at
Santa Clara University. Pedersen and Peter Hilton
co-authored A Mathematical Tapestry: Demonstrating
the Beautiful Unity of Mathematics 
, which used paper
folding to show connections between geometry,
number theory, and group theory. Pedersen was an
AMS member since 1979.

Spielerei  —

"On the most recent visit, Arthur had given him
a brightly colored cube, with sides you could twist
in all directions, a new toy that had just come onto
the market."

— Daniel Kehlmann, F: A Novel  (2014),
     translated from the German by
     Carol Brown Janeway

Nicht Spielerei  —

A passage suggested by the 2006 Oxford University Press title
The Architecture of Modern Mathematics , edited by 
José Ferreirós and Jeremy Gray —

Jeremy Gray, Plato's Ghost: The Modernist Transformation of Mathematics ,
Princeton, 2008 —

"Here, modernism is defined as an autonomous body of ideas,
having little or no outward reference, placing considerable emphasis
on formal aspects of the work and maintaining a complicated—
ndeed, anxious— rather than a naïve relationship with the day-to-day
world, which is the de facto view of a coherent group of people,
such as a professional or discipline-based group that has a high sense
of the seriousness and value of what it is trying to achieve.
This brisk definition…."

William Butler Yeats —

“Poets and Wits about him drew;
‘What then?’ sang Plato’s ghost.
   ‘What then?’

‘The work is done,’
   grown old he thought, 
‘According to my boyish plan;
Let the fools rage,
   I swerved in naught,
Something to perfection brought’;
But louder sang that ghost,
   ‘What then?’

Spielraum

Filed under: Uncategorized — Tags: — m759 @ 1:27 PM

From the concluding paragraph of a new book by
mathematician Michael Harris:

"A team of eminent scholars is completing a definitive
edition of Hausdorff’s collected works—'unique
in the annals of mathematical publishing'— with the
care befitting the literary figure he undoubtedly was….
he is honored as, perhaps, the first modern
mathematician to give a name to what we have been
calling the 'relaxed field'— he called it the
'Spielraum  of thought'— and as a mathematician
who never lost his sensitivity to his chosen field’s
problematic attractions while remaining fully aware that
every veil lifted only reveals another veil."

— Harris, Michael, Mathematics without Apologies:
Portrait of a Problematic Vocation  
(2015-01-18)
