Book Description

Excerpt from A Treatise on the Teeth of Wheels: Demonstrating the Best Forms Which Can Be Given to Them for the Purposes of Machinary Improvement in science is frequently very slow, being retarded either by ignorance or prejudice, both of which too often prevail among those who have the best opportunity of making practical observations. Mechanics, in general, conduct their operations according to a certain routine, which they have acquired by experience; and as they are little versed in theory, or the mathematical principles of what they profess, they seldom think of going beyond the beaten track in which they have been accustomed to move. Some of our greatest engineers, indeed, have been men of no education; they attained to eminence merely by the natural force of their genius, and of course were liable to fall into mistakes, which the man versed in mathematical knowledge could either rectify or avoid.
