245 페이지 - The square described on the hypothenuse of a rightangled triangle is equal to the sum of the squares described on the other two sides.
41 페이지 - I intend, in some cases, to apply a degree of cold, not capable of reducing the steam to water, but of contracting it considerably, so that the engines shall be worked by the alternate expansion and contraction of the steam. " Lastly, Instead of using water to render the piston or other parts of the engines air and steam-tight, I employ oils, wax, resinous bodies, fat of animals, quicksilver, and other metals, in their fluid state.
80 페이지 - Having made my single reciprocating engines very regular in their movements, I considered how to produce rotative motions from them in the best manner ; and amongst various schemes which were subjected to trial, or which passed through my mind, none appeared so likely to answer the purpose as the application of the crank, in the manner of the common turning lathe...
