Page 508 - Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.
Page 553 - If a window is broken and left unrepaired, people walking by will conclude that no one cares and no one is in charge. Soon, more windows will be broken, and the sense of anarchy will spread from the building to the street on which it faces, sending a signal that anything goes.
Page 572 - It is my belief that flight is possible and, while I am taking up the investigation for pleasure rather than profit, I think there is a slight possibility of achieving fame and fortune from it. It is almost the only great problem which has not been pursued by a multitude of investigators, and therefore carried to a point where further progress is very difficult. I am certain I can reach a point much in advance of any previous workers in...

Page 178 - ... two thousand times as much as the electrons. Thus, more than 99.99 per cent of the atom's mass is contained in the nucleus, and since mass is a manifestation of energy, it follows that practically all of the atom's energy also resides there. Moreover, the protons are positively charged particles, and the number of protons in the nucleus equals the number of electrons outside, for the atom as a whole is electrically neutral. Therefore, since it is the number of electrons outside that determines...
