 But even when its temperature does not exceed that of boiling water, the wire produces a dark ascending current. This, I say, is due to the distribution of the floating matter. Imagine the wire clasped by the mote-filled air. My idea is that it heats...  Scientific Papers: 1881-1887 - Page 149by John William Strutt Baron Rayleigh - 1900Full view - About this book
