Famous quotes containing the words frame, aspect and/or ratios:
“she drew back a while,
Then, yielding to the irresistible joy,
With frantic gesture and short breathless cry
Folded his frame in her dissolving arms.
Now blackness veiled his dizzy eyes, and night
Involved and swallowed up the vision; sleep,
Like a dark flood suspended in its course,
Rolled back its impulse on his vacant brain.”
—Percy Bysshe Shelley (1792–1822)
“[Convey to your child] that you understand how hard it can be to lose a friend, that under the circumstances feeling sad, angry, hurt or rejected is perfectly normal, that the friendship had some good things and some bad things to it and that neither aspect should be overlooked. . . . Children should be helped to realize that in time they’ll find other friends—but they mustn’t expect a new friend to “replace” a former one.”
—Myron Brenton (20th century)
“Typography is not only a technology but is in itself a natural resource or staple, like cotton or timber or radio; and, like any staple, it shapes not only private sense ratios but also patterns of communal interdependence.”
—Marshall McLuhan (1911–1980)
