Famous quotes containing the words physical, memory and/or limits:
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“We turned to other things.
I haven’t any memory have you?
Of ever coming to the place again
To see if the birds lived the first night through.
And so at last to learn to use their wings.”
—Robert Frost (1874–1963)
““... Ain’t it a caution to us not to fix
No limits to what rose in rubbing sticks
On fire to scare away the pterodix
When man first lived in caves along the creeks?”
“Marvelous world in nineteen-twenty-six.””
—Robert Frost (1874–1963)
