It's equally astonishing that the birds are able to measure its relative strength with such accuracy that they can trace it back to its source simply by sensing in which direction it becomes marginally stronger. But a turkey vulture is exceptionally well-equipped among birds, with wide-open nostrils and extremely well-developed sense organs within them.

The American child is a highly intelligent human being - characteristically sensitive, humorous, open-minded, eager to learn, and has a strong sense of excitement, energy, and healthy curiosity about the world in which he lives. Lucky indeed is the grown-up who manages to carry these same characteristics into adult life. It usually makes for a happy and successful individual.
Walt Disney
Philosophy treats of physics where a more careful knowledge is required because the problems which come under this head are numerous... So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers.
Vitruvius
Sport in the sense of a mass-spectacle, with death to add to the underlying excitement, comes into existence when a population has been drilled and regimented and depressed to such an extent that it needs at least a vicarious participation in difficult feats of strength or skill or heroism in order to sustain its waning life-sense.
Lewis Mumford
Thou who didst waken from his summer dreams The blue Mediterranean, where he lay, Lull'd by the coil of his crystalline streams Beside a pumice isle in Bai's bay, And saw in sleep old palaces and towers Quivering within the wave's intenser day, All overgrown with azure moss and flowers So sweet, the sense faints picturing them.
Percy Bysshe Shelley
Science has taught... me to be careful how I adopt a view which jumps with my preconceptions, and to require stronger evidence for such belief than for one to which I was previously hostile. My business is to teach my aspirations to conform themselves to fact, not to try and make facts harmonise with my aspirations.
Thomas Henry Huxley
