« I have always liked to analyse data but have
never been fond of math and its ‘funky’
letter abbreviations.
The Statistics class was a real eye-opener and
taught me how to use math to analyse data
and this helps me to perform better in my
daily tasks. »

GALTON, 1908
Some people hate the very name of Statistics, but I
find them full of beauty and interest.
Whenever they are not brutalized, but delicately
handled by the higher methods, and are warily
interpreted, their power of dealing with complicated
phenomena is extraordinary.
They are the only tools by which an opening can be
cut through the formidable thicket of difficulties that
bars the path of those who pursue the Science of man.

L’Ingénieur Général
Henri SABATIER
« Sans doute, vous ne serez pas aussitôt une
lumière de la question ; mais une spécialité est un
bien qui s’acquiert lentement, formé d’apports
incessants, gros et petits, comme des mille bribes
qu’on accroche au passage et qui permettent de
pénétrer insensiblement plus avant dans la partie
qu’on a faite sienne.
Si aujourd’hui, rien ne vous tente, laissez-vous
porter pendant la durée du Cours. D’ici là, des
éléments d’orientation vous seront apparus. Si à ce
moment, rien ne vous a encore décidé, la Direction
du Cours vous aiguillera. »

Proverbe chinois
J ’entends et j’oublie.
Je vois et je me souviens.
Je fais et je comprends.
Mark Rothko (1903 - 1970)
« The progression of a painter's work
as it travels in time from point to
point, will be toward clarity.. toward
the elimination of all obstacles
between the painter and the idea..
and the idea and the observer.. »
