Famous quotes containing the words actual and/or particles:
“To develop an empiricist account of science is to depict it as involving a search for truth only about the empirical world, about what is actual and observable.... It must involve throughout a resolute rejection of the demand for an explanation of the regularities in the observable course of nature, by means of truths concerning a reality beyond what is actual and observable, as a demand which plays no role in the scientific enterprise.”
—Bas Van Fraassen (b. 1941)
“The atoms of Democritus
And Newton’s particles of light
Are sands upon the Red Sea shore,
Where Israel’s tents do shine so bright.”
—William Blake (1757–1827)
