Famous quotes containing the words mass and/or start:
“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)
“We shall make mistakes, but they must never be mistakes which result from faintness of heart or abandonment of moral principles. I remember that my old school master Dr. Peabody said in days that seemed to us then to be secure and untroubled, he said things in life will not always run smoothly, sometimes we will be rising toward the heights and all will seem to reverse itself and start downward. The great thing to remember is that the trend of civilization itself is forever upward.”
—Franklin D. Roosevelt (1882–1945)
