A quotation by Robert Boyle
Father of Chemistry and Uncle of the Earl of Cork
[On his tombstone]
Quoted in A L Mackay, Dictionary of Scientific Quotations (London 1994)
I confess, that after I began...to discern how useful mathematicks may be made to physicks, I have often wished that I had employed the speculative part of geometry, and the cultivation of the specious Algebra I had been taught very young, a good part of that time and industry, that I had spent about surveying and
fortification (of which I remember I once wrote an entire treatise) and other parts of practick mathematicks.
