George Ellery Hale Quote

Light is the most universal of all languages. Its messages reach us with equal faculty from the depths of the universe and from the electrons whirling in the nearest atom. Like the hieroglyphics of the Egyptians, its tones are silent, but unlike them, it tells of the present as well as of the past.
