Famous quotes containing the words world, record and/or progression:
“I have not loved the world, nor the world me;
I have not flatter’d its rank breath, nor bow’d
To its idolatries a patient knee.”
—George Gordon Noel Byron (1788–1824)
“We are at war with the most dangerous enemy that has ever faced mankind in his long climb from the swamp to the stars, and it has been said if we lose that war, and in so doing lose this way of freedom of ours, history will record with the greatest astonishment that those who had the most to lose did the least to prevent its happening.”
—Ronald Reagan (b. 1911)
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
