The launch of Nautilus, the world's first atomic submarine marked a transition in naval warfare-a transition as sudden as that associated with the Monitor.
The aeroplane. . . is not capable of unlimited magnification. It is not likely that it will ever carry more than five or seven passengers. High speed monoplanes will carry even less. . . . Over cities, the aerial sentry or policeman will be found. A thousand aeroplanes flying to the opera must be kept in line and each allowed to alight upon the roof of the auditorium, in its proper turn.
In size the electron bears the same relation to an atom that a baseball bears to the earth. Or, as Sir Oliver Lodge puts it, if a hydrogen atom were magnified to the size of a church, an electron would be a speck of dust in that church.
It may be that the invention of the aeroplane flying-machine will be deemed to have been of less material value to the world than the discovery of Bessemer and open-hearth steel, or the perfection of the telegraph, or the introduction of new and more scientific methods in the management of our great industrial works. To us, however, the conquest of the air, to use a hackneyed phrase, is a technical triumph so dramatic and so amazing that it overshadows in importance every feat that the inventor has accomplished.
