Famous quotes containing the words magic and/or number:
“Oh, what a catastrophe for man when he cut himself off from the rhythm of the year, from his unison with the sun and the earth.

—D.H. (David Herbert)
“Can it be, that the Greek grammarians invented their dual number for the particular benefit of twins?”
