   I seem to recall from Aubrey that one of Elizabeth's scholars applied   
   mathematics to gunnery, possibly Dr Dee before he became an occultist.   
      
   The Parliamentary officer Nathaniel Nye directed cannon in the English   
   civil war and published a book on the mathematics of it in 1647, in   
   which he cited a much earlier Italian mathematician, Tartaliga, who   
   wrote on the subject in 1537.
