Page 253 - If there is one thing more certain than another, it is that, as the popular element increases, that government recedes from aristocracy and monarchy toward republicanism.
Page 179 - When light is scattered by particles which are very small compared with any of the wavelengths, the ratio of the amplitudes of the vibrations of the scattered and incident light varies inversely as the square of the wave-length, and the intensity of the lights themselves as the inverse fourth power.
Page 223 - ... the yellow-green afford the most light ; the red give less light, but much more heat; while the still larger and less frequent vibrations, which have no effect on the sense of sight, may be supposed to give rise to the least refrangible rays, and to constitute invisible heat.
Page 222 - ... no more. So far as I know, no physicist of eminence reasserted Melloni's principle with equal emphasis, till JW Draper, in 1872. Only sixteen years ago, or in 1872, it was almost universally believed that there were three different entities in the spectrum, represented by actinic, luminous and thermal rays.
Page 223 - England, of whom it was observed, that, "if he had but known a little law, he would have known a little of everything.
Page 294 - ... uniformly white, without the least appearance of any of the coloured rings ; and yet, by viewing them through a prism, great multitudes of these rings have discovered themselves. And in like manner, plates of Muscovy glass, and bubbles of glass blown at a lamp-furnace, which were not so thin as to exhibit any colours to the naked eye, have through the prism exhibited a great variety of them ranged irregularly up and down in the form of waves. And so bubbles of water, before they began to exhibit...

Page 525 - But it is startling to find a referee expressing the opinion that 'the paper is nothing but nonsense, unfit even for reading before the Society.' Another remarks ' that ihe whole investigation is confessedly founded on a principle entirely hypothetical, from which it is the object to deduce a mathematical representation of the phenomena of elastic media. It exhibits much skill and many remarkable...
Page 418 - ... which we had to overcome. We found, after a few trials, that we could get over it by wetting the shot with alcohol. We will try again with dry shot. Three shots have gone through and nothing has happened. Now we will try one wetted with alcohol, and I expect it will break the film at once. There ! it has gone ! The apparatus for executing the photography of a breaking soap film will of necessity be more complicated than before, because we have to time the spark exactly with the breaking of the...
Page 40 - There is now, without the grating, a very trivial flaring ;* but when the grating is in position again — though a great part of the sound is thereby stopped out — the effect is far more powerful than when no obstruction intervened. The grating acts, in fact, the part of a lens. It concentrates the sound upon the flame, and so produces the intense magnification of effect which we have seen. [The exterior radius of the...
