Famous quotes containing the words silk and/or mass:
“O bid me mount and sail up there
Amid the cloudy wrack,
For Peg and Meg and Paris’ love
That had so straight a back,
Are gone away, and some that stay
Have changed their silk for sack.”
—William Butler Yeats (1865–1939)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
