### Famous quotes containing the word physics:

“We must be physicists in order ... to be creative since so far codes of values and ideals have been constructed in ignorance of *physics* or even in contradiction to *physics*.”

—Friedrich Nietzsche (1844–1900)

“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in *physics* because they are true in ethics.”

—Henry David Thoreau (1817–1862)

“But this invites the occult mind,

Cancels our *physics* with a sneer,

And spatters all we knew of denouement

Across the expedient and wicked stones.”

—Karl Shapiro (b. 1913)
