Famous quotes containing the word physics:
“The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.”

“Mathematics should be mixed not only with physics but with ethics.”
—Henry David Thoreau (1817–1862)

Cancels our physics with a sneer,
And spatters all we knew of denouement
Across the expedient and wicked stones.”
