## A quotation by Daniel Bernoulli

...it would be better for the true physics if there were no mathematicians on earth.

Quoted in

*The Mathematical Intelligencer*

**13**(1991).

... there is no philosophy which is not founded upon knowledge of the phenomena, but to get any profit from this knowledge it is absolutely necessary to be a mathematician.

Quoted in C Truesdell,

*Essays in the History of Mathematics*
