Famous quotes containing the words numbers, representing, scientific and/or quantities:
“He bundles every forkful in its place,
And tags and numbers it for future reference,
So he can find and easily dislodge it
In the unloading. Silas does that well.
He takes it out in bunches like birds nests.”
—Robert Frost (18741963)
“... today we round out the first century of a professed republic,with woman figuratively representing freedomand yet all free, save woman.”
—Phoebe W. Couzins (18451913)
“A superstition which pretends to be scientific creates a much greater confusion of thought than one which contents itself with simple popular practices.”
—Johan Huizinga (18721945)
“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] (18321898)
