“ Even now, within an ace of thirty years from this intellectual cataclysm, poor old Oxford is only just recovering from a protracted state of vertigo, and settling down again to useful work. It is sad that she should have to chronicle the early loss of one who has been a main agent in the revolution. ”

“ There is a common type of mind which fails to see a proof which is not of the character of demonstration, and which, in its absence, neglects to use the faculty of judgment and decision so necessary in the common affairs of business.
The computing school, and especially those who teach its physical branches, very correctly and consistently insist upon the solving of problems as a test of thorough knowledge. ”

“ They may adopt artistic or literary pursuits, they may choose the professions of law or of medicine. In all these, the attempt to reduce the subject-matter laid before them to the strict conditions of an equation or a ratio, so far from being a fruitful mental effort, may absolutely prove a hindrance. ”

“ Englishmen, with their characteristic tenacity of existing forms, had retained all but unchanged in their large public schools and in the older universities a form of intellectual culture which really originated in the middle ages, or at the latest with the restoration of learning. ”

“ What is the 'kinetic energy' of a moving mechanical system? A shot of 1,000 pounds moving at 1,600 feet per second strikes a fixed target. How far will the shot penetrate the target exerting upon it an average pressure equal to the weight of 12,000 tons? ”

“ A solid right circular cone of homogeneous iron is 64 inches in height, and its mass is 8,192 pounds. The cone is cut by a plane perpendicular to the axis, so that the mass of the small cone removed is 686 pounds. Find the height of the center of gravity of the truncated portion remaining, above the base of the cone.
"4. A heavy body starting from rest slides down a smooth plane inclined 30° to the horizon. How many seconds will it occupy in sliding 240 feet down the plane, and what will be its velocity after traversing this distance? ”
