Page 392 - There is now reigning in philosophy and in science an apathetic acquiescence in the conclusion that no coherent account can be given of nature as it is disclosed to us in senseawareness, without dragging in its relations to mind."
Page 663 - If a circuit consisting of a parallelplate condenser and inductance be maintained in oscillation by means of a thermionic valve, a small change in distance apart of the plates produces a change in the frequency of the oscillations which can be accurately determined by methods described. It is shown that changes so small as
Page 209 - of the slider. Static friction is a function of the molecular weight of the lubricant; and in a simple chemical series of chain compounds such as fatty acids and alcohols or paraffins a good lubricant will be found if one goes high enough in the series. But it is not a simple function,
Page 541 - Probably the best way in which a singlelayer coil can be constructed with great precision is by winding uniform round wire in a spiral groove accurately cut in a circular cylinder, as first suggested by Viriamu Jones and as exemplified in the work of the National Physical Laboratory. If the cylinder is conducting and
Page 103 - Above a certain voltage the intensity of any line per unit number of electrons reaching the anode attains a saturation value, in agreement with the quantum hypothesis, which requires that the number of quanta radiated be proportional to the number of collisions, and hence (approximately) to the number of electrons present. Curves are given
Page 439 - Two octets may hold 1, 2 or sometimes even 3 pairs of electrons in common. A stable pair and an octet may hold a pair of electrons in common. An octet may share an even number of its electrons with 1, 2, 3 or 4 other octets. No electrons
Page 542 - It is then clearly possible to join successive layers of the two solenoids systematically in series by very short connectors at the ends, in such a way that the current goes alternately up a layer of one solenoid and down a layer of the other, and that the small effects of each pair of short connectors
Page 209 - weight is disturbed thereby. The relation of lubricating qualities to viscosity broadly resembles that to molecular weight. In a simple chemical series lubrication and viscosity change in much the same way with molecular weight, but that there is no fundamental relation between viscosity and lubrication is shown by the following figures :— Viscosity
Page 250 - faults diminishes gradually to zero, and the valley dies out on the broad top of the anticline. Downhill, towards the plunging nose of the anticline, the trough is closed abruptly by a crossfault nearly at right angles to the anticlinal axis. The length of the
Page 542 - however, is due to the long conductors necessary to connect the far end of each coil with the near end of the next, which may interfere greatly with the direction and uniformity of the field due to the spiral windings. All the advantages of precise winding may be obtained, and at the same time the (small) effect of
