Famous quotes containing the words experiments and/or rays:
“My experiments did not turn out quite like yours, Henry. But science, like love, has her little surprises.”
—William Hurlbut (1883?)
“I am often mad, but I would hate to be nothing but mad: and I think I would lose what little value I may have as a writer if I were to refuse, as a matter of principle, to accept the warming rays of the sun, and to report them, whenever, and if ever, they happen to strike me.”
—E.B. (Elwyn Brooks)
