When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles ofa real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, butthrough television and telephony we shall seeand hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instrumentsthrough which we shall be able to do thiswill be amazingly simple compared with ourpresent telephone. A man will be able to carryone in his vest pocket.
