  • The history of men of science has one peculiar advantage, as it shows the importance of little things in producing great results. Smeaton learned his principle of constructing a lighthouse, by noticing the trunk of a tree to be diminished from a curve to a cyclinder ... and Newton, turning an old box into a water-clock, or the yard of a house into a sundial, are examples of those habits of patient observation which scientific biography attractively recommends.
