The author, a Pure Mathematician and a Structural Engineer, tries
to prove that there cannot be any relationships between pure
mathematics an concrete architecture, by first mentioning the
variety of mathematics invented by man over the centuries. He
defines pure mathematics, illustrating it by examples from
Euclidean geometry and non-Euclidean geometries and pointing out
the essential reality of the most abstract mathematics, including
the essential importance of Riemannian geometry to the
Einsteinian general theory of relativity.
He then considers the essential quality of concreteness of all
architecture and of its many facts, pointing out that the only
real architecture must be built architecture and that no
theoretician of architecture is an architect.
He next explains that his work with some of the greatest
architects of this century has shown him that architecture is one
of the most demanding activities of man and that, interested as
he is about architecture, he does not dare to work as an
architect, and is satisfied with only helping architects with his
knowledge of structures.
Finally, he takes off his "mathematician hat" and put on his
"structural engineering hat" and suddenly realizes that, yes,
applied mathematics is so important to architecture that, if
mathematics had not been invented, architects would have been
compelled to invent it themselves.
There are so many knowledgeable architects and theoreticians of
architecture at this meeting that he does not dare to complete
with them, and brings his presentation to a close.
