"Conductivity" Quotes from Famous Books

... these little things begin to satisfy me yet," he told me nearly a year ago. "Either they increase the central energy without affecting the nerves, or they simply increase the available energy by lowering the nervous conductivity; and all of them are unequal and local in their operation. One wakes up the heart and viscera and leaves the brain stupefied, one gets at the brain champagne fashion, and does nothing good for the solar plexus, and what I want—and what, if it's an earthly possibility, I mean to have—is a stimulant ...

... course of the steam in a plant, the next advantage of the use of superheated steam is the absence of water in the steam pipes. The thermal conductivity of superheated steam, that is, its power to give up its heat to surrounding bodies, is much lower than that of saturated steam and its heat, therefore, will not be transmitted so rapidly to the walls of the pipes as when saturated steam is flowing through the pipes. The loss of heat ...

... almost say changing from zero to infinity, and the reverse, instantly, is one which suggests some very far-reaching inquiries to the electrician and the physicist. What is the nature of electrical conductivity or resistance, and how is it so ...

... dual or multiple personality aside, and putting the matter very simply, I believe that my soul made a right choice in you my wife. I believe that alcohol was necessary for a while to put my body, even at its expense, into a state of conductivity, so that my soul, when I was somewhat alcoholized, could gain some expression; give some glimpses of itself and suggest the trend of my powers. For this reason I believe that some men are made to drink and drug—but that is another subject ...

... augmented, these images blended into a continuous ring of light. At a particular instant the electro-magnet was excited, currents were evolved in the rotating cube, and the strength of these currents, which increases with the conductivity of the cube for electricity, was practically estimated by the time required to bring the cube and its associated mirrors to a state of rest. With bismuth this time amounted to a score of seconds or more: a cube of copper, on the contrary, was struck almost ...

... containing over 2 or 3 per cent. of salt. The best way to add salt to a liquid rheostat is to make a strong solution in a separate vessel and add as much of this solution as is needed. This avoids the annoying increase in conductivity of the solution which happens when the salt itself is added and ...

... fig. 9 shows the relative conductivity (reciprocal of resistance) of all the strengths of sulphuric acid solutions, and by its aid and the figures in the preceding table, the specific resistance of any given ...
