Siméon Poisson D'Arcy Thompson Gaston Tarry


A quotation for today

D'Arcy Thompson (1860 - 1948)

Cell and tissue, shell and bone, leaf and flower, are so many portions of matter, and it is in obedience to the laws of physics that their particles have been moved, moulded and conformed. They are no exceptions to the rule that God always geometrizes. Their problems of form are in the first instance mathematical problems, their problems of growth are essentially physical problems, and the morphologist is, ipso facto, a student of physical science.

On Growth and Form (Cambridge 1917)

Another quotation by one of today's mathematicians
