Seite 336 - Great fleas have little fleas upon their backs to bite 'em, | And little fleas have lesser fleas, and so ad infinitum.
Seite 182 - Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show.
Seite 56 - Just so it is in the mind ; would you have a man reason well, you must use him to it betimes, exercise his mind in observing the connection of ideas and following them in train. Nothing does this better than mathematics, which therefore I think should be taught all those who have the time and opportunity, not so much to' make them mathematicians as to make them reasonable creatures...
Seite 212 - But who shall parcel out His intellect by geometric rules, Split like a province into round and square? Who knows the individual hour in which His habits were first sown, even as a seed?

Seite 170 - I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Seite 370 - In the first course there was a shoulder of mutton, cut into an equilateral triangle, a piece of beef into a rhomboides, and a pudding into a cycloid. The second course was two ducks, trussed up into the form of fiddles; sausages and puddings resembling flutes and hautboys, and a breast of veal in the shape of a harp. The servants cut our bread into cones, cylinders, parallelograms, and several other mathematical figures.
Seite 244 - Go, wondrous creature! mount where Science guides; Go, measure earth, weigh air, and state the tides; Instruct the planets in what orbs to run, Correct old Time, and regulate the sun; Go, soar with Plato to th...
Seite 378 - Music has charms to soothe a savage breast, To soften rocks, or bend a knotted oak. I've read that things inanimate have moved, And, as with living souls, have been informed, By magic numbers and persuasive sound.
