## A quotation by James Jeans

The essential fact is that all the pictures which science now draws of nature, and which alone seem capable of according with observational facts, are mathematical pictures.

Quoted in J R Newman,

*The World of Mathematics*(New York 1956).

From the intrinsic evidence of his creation, the Great Architect of the Universe now begins to appear as a pure mathematician.

*Mysterious Universe*.

We may as well cut out the group theory. That is a subject that will never be of any use in physics.

[discussing a syllabus in 1910]

Quoted in D MacHale,

*Comic Sections*(Dublin 1993)

... nature seems very conversant with the rules of pure mathematics, as our mathematicians have formulated them in their studies, out of their own inner consciousness and without drawing to any apppreciable extent on their experience of the outer world.
