Page 556 - Here is unfolded to us a new and astonishing world one which it is hard to conceive should contain no possibilities of transmitting and receiving intelligence. Rays of light will not pierce through a wall, nor, as we know only too well, through a London fog. But the electrical vibrations of a yard or more in wave-length of which I have spoken will easily pierce such mediums, which to them will be transparent. Here, then, is revealed the bewildering possibility of telegraphy without wires, posts,...
Page 459 - ... the art of directing the great sources of power in nature for the use and convenience of man, as the means of production and of traffic in states.
Page 557 - This is no mere dream of a visionary philosopher. All the requisites needed to bring it within grasp of daily life are well within the possibilities of discovery, and are so reasonable and so clearly in the path of researches which are now being actively prosecuted in every capital of Europe that we may any day expect to hear that they have emerged from the realms of speculation to those of sober fact.5 If Crookes...
Page 485 - ... which is of use to the grantee only because the people as a whole allow him to use it. It is eminently right that he should be allowed to make ample profit from his development of...
Page 464 - Engineering is the art of organizing and directing men and of controlling the forces and materials of nature for the benefit of the human race.
Page 557 - ... miles; secondly, more delicate receivers which will respond to wavelengths between certain defined limits and be silent to all others; thirdly, means of darting the sheaf of rays in any desired direction, whether by lenses or reflectors, by the help of which the sensitiveness of the receiver (apparently the most difficult of the problems to be solved) would not need to...
Page 555 - The discharge, whatever may be its nature, is not correctly represented (employing for simplicity the theory of Franklin) by the single transfer of an imponderable fluid from one side of the jar to the other; the phenomena require us to admit the existence of a principal discharge in one direction, and then several reflex actions backward and forward, each more feeble than the preceding, until the equilibrium is obtained.
Page 627 - States, and for other purposes, have considered the same, and recommend that the bill do pass with the following amendment: In line 7, page 1, strike out the words " has been or," and insert the word " hereafter " after the word
Page 556 - ... which to them will be transparent Here, then, is revealed the bewildering possibility of telegraphy without wires, posts, cables, or any of our present costly appliances. Granted a few reasonable postulates, the whole thing comes well within the realms of possible fulfillment. At...
Page 556 - What remains to be discovered is firstly, simpler and more certain means of generating electrical rays of any desired wave-length, from the shortest, say a few feet, which will easily pass through buildings and fogs, to those long waves whose lengths are measured by tens, hundreds, and thousands of miles ; secondly, more delicate receivers which will respond to wave-lengths between certain defined limits and be silent to all others...
