Famous quotes containing the word phenomena:
“Many of the phenomena of Winter are suggestive of an inexpressible tenderness and fragile delicacy. We are accustomed to hear this king described as a rude and boisterous tyrant; but with the gentleness of a lover he adorns the tresses of Summer.”
—Henry David Thoreau (1817–1862)
