Famous quotes containing the words numbers, representing, scientific and/or quantities:
“Individually, museums are fine institutions, dedicated to the high values of preservation, education and truth; collectively, their growth in numbers points to the imaginative death of this country.”
—Robert Hewison (b. 1943)
“... today we round out the first century of a professed republic,—with woman figuratively representing freedom—and yet all free, save woman.”
—Phoebe W. Couzins (1845–1913)
“The scientific mind is atrophied, and suffers under inherited cerebral weakness, when it comes in contact with the eternal woman—Astarte, Isis, Demeter, Aphrodite, and the last and greatest deity of all, the Virgin.”
—Henry Brooks Adams (1838–1918)
“The Walrus and the Carpenter
Were walking close at hand:
They wept like anything to see
Such quantities of sand:
“If this were only cleared away,”
They said, “it would be grand!”
“If seven maids with seven mops
Swept it for half a year,
Do you suppose,” the Walrus said,
“That they could get it clear?”
“I doubt it,” said the Carpenter,
And shed a bitter tear.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
