On Radiant Matter: A Lecture Delivered to the British Association for the Advancement of Science, at Sheffield, Friday, August 22, 1879 (Classic Reprint) by William Crookes (Paperback / softback, 2015)
Excerpt from On Radiant Matter: A Lecture Delivered to the British Association for the Advancement of Science, at Sheffield, Friday, August 22, 1879 To throw light on the title of this lecture I must go back more than sixty years - to 1816. Faraday, then a mere student and ardent experimentalist, was 24 years old, and at this early period of his career he delivered a series of lectures on the General Properties of Matter, and one of them bore the remarkable title, On Radiant Matter. The great philosopher's tes of this lecture are to be found in Dr. Bence Jones's Life and Letters of Faraday, and I will here quote a passage in which he first employs the expression Radiant Matter: - If we conceive a change as far beyond vaporisation as that is above fluidity, and then take into account also the proportional increased extent of alteration as the changes rise, we shall perhaps, if we can form any conception at all, t fall far short of Radiant Matter; and as in the last conversion many qualities were lost, so here also many more would disappear. Faraday was evidently engrossed with this far-reaching speculation, for three years later - in 1819 - we find him bringing fresh evidence and argument to strengthen his startling hypothesis. His tes are w more extended, and they show that in the intervening three years he had thought much and deeply on this higher form of matter. He first points out that matter may be classed into four states - solid, liquid, gaseous, and radiant - these modifications depending upon differences in their several essential properties. He admits that the existence of Radiant Matter is as yet unproved, and then proceeds, in a series of ingenious analogical arguments, to show the probability of its existence.
