Suspecting polarisation as the thing required, I shifted and shifted the mirrors, changing their relation, until at last, in a great degree, so far as I was concerned, by chance, things came right between them, and I saw the mountains blue and steady and clear. I stepped forward, and my feet were among the heather. All I knew of the way to the cottage was that we had gone through a pine-forest.
Such experiments, however, are in reality more beautiful and ingenious than instructive, since ignited as well as obscure bodies possess the power of throwing back light incident upon them, and will consequently transmit to us from the neighbourhood of the sun rays partly direct, partly reflected, of which a certain proportion will exhibit the peculiarity known as polarisation.
His chief scientific interest was optics, and he invented the kaleidoscope, and improved Wheatstone's stereoscope by introducing the divided lenses. In 1815 he was elected a member of the Royal Society, and, later, was awarded the Rumford gold and silver medals for his discoveries in the polarisation of light. In 1831 he was knighted.
He was one of the founders of the British Association in 1831. His scientific investigations and discoveries embraced the subjects of heat, light, polarisation, and specially glaciers. In connection with the last of these he wrote Travels through the Alps , Norway and its Glaciers , Tour of Mont Blanc and Monte Rosa , and Papers on the Theory of Glaciers.
It appeared beyond question that light must be interpreted as a vibratory process in an elastic, inert medium filling up universal space. It also seemed to be a necessary consequence of the fact that light is capable of polarisation that this medium, the ether, must be of the nature of a solid body, because transverse waves are not possible in a fluid, but only in a solid.
This "secondary" or reacting current is evidently due to the polarisation of the foils that is to say, the electro- positive and electro-negative gases collected on them. Professor Groves constructed a gas battery on this principle, the plates being of platinum and the two gases surrounding them oxygen and hydrogen, but the most useful development of it is the accumulator or storage battery.
And each time that such a polarisation of attention took place, the child began to be completely transformed, to become calmer, more intelligent, and more expansive; it showed extraordinary spiritual qualities, recalling the phenomena of a higher consciousness, such as those of conversion.
The reason may have been a very simple one: the polarisation of signals returning from the Moon varies from one moment to the other, so if you have been transmitting with horizontal polarisation and go over to reception it is very easy to miss the answer of the other station if the polarisation has changed."
But there is no longer any of the horrible merging, mingling self-abnegation of love. There is only the pure duality of polarisation, each one free from any contamination of the other. In each, the individual is primal, sex is subordinate, but perfectly polarised. Each has a single, separate being, with its own laws. The man has his pure freedom, the woman hers.
Professor Bjerknes, if I remember the name, has produced all the phenomena of magnetic attraction, repulsion, and polarisation, by air vibrations corresponding, I suppose, to certain fixed musical notes. Why might not something similar to this be true of atomic, as well as of larger, bodies?" If the roof of my house had fallen in, I should not have been more surprised than at this quiet remark.
