Portrait of Augustus Edward Hough Love Augustus Edward Hough Love,  1911 Encyclopædia Britannica (1911)

“ Finite Bending of Thin Rod.—The equation
curvature = bending moment ÷ flexural rigidity may also be applied to the problem of the flexure in a principal plane of a very thin rod or wire, for which the curvature need not be small. When the forces that produce the flexure are applied at the ends only, the curve into which the central-line is bent is one of a definite family of curves, to which the name elastica has been given, and there is a division of the family into two species according as the external forces are applied directly to the ends or are applied to rigid arms attached to the ends

Portrait of John Ruskin John Ruskin,  The Bible of Amiens (1884)

“ It is simple and severe at the bottom, and daintily traceried and pinnacled at the top, and yet seems all of a piece—though it isn't—and everybody must like the taper and transparent fretwork of the flèche above, which seems to bend to the west wind,—though it doesn't—at least, the bending is a long habit, gradually yielded into, with gaining grace and submissiveness, during the last three hundred years. ”

Portrait of E. F. Benson E. F. Benson,  Daisy's Aunt

“ But, as I said, when the pall lifted a little, that was the worst of all, because then, for a moment it might be, or for an hour or two, I knew that life and youth and joy were just as dominant and as triumphant as ever in the world, and that it was I who had got on the wrong side of things, and saw them left-handed, and could be only conscious of this hideous nightmare of suffering. ”
