Professor Farmer, the botanist, investigates cancer, and the ordinary educated man, familiar though he is with their general results, would find it hard to say which were the chemists and which the physicists among Professors Dewar and Ramsey Lord Rayleigh and Curie. The classification of sciences that was such a solemn business to our grandfathers is now merely a mental obstruction.
Now, the scientific experiments of the last two years have brought this mystery of the celestial spaces right down into our earthly laboratories. M. and Madame Curie have discovered the singular metal radium, which seems to send out light, heat, and other rays incessantly, without, so far as has yet been determined, drawing the required energy from any outward source.
She set herself the task of finding out this agent and in conjunction with her husband, Professor Pierre Curie, made many tests and experiments. Finally in the ore of pitchblende they found not only one but three substances highly radio-active.
The rays which come from the tube, in conditions now well known, are not deviated by a magnet, and, as M. Curie and M. Sagnac have conclusively shown, they carry no electric charge.
One of these was Curie, now of London, whose works are on the counters of some of our bookstores, and probably in the hands of some of my audience. This gentleman, whom Dr.
But the importance of this discovery was soon completely overshadowed by the discovery of radium by Madame Curie, working with her husband, Professor Pierre Curie, at the École Polytechnique in Paris.
M. and Madame Curie then commenced those celebrated experiments which brought them to the discovery of radium. Their method of research has been justly compared in originality and importance to the process of spectrum analysis.
It might therefore have been the case that it pre-existed in the gases extracted from radium; but a remarkable experiment by M. Curie and Sir James Dewar seems to show convincingly that this cannot be so.
"By a woman?" hinted Don Aloysius, with a smile. She shrugged her shoulders carelessly. "Very often! Marja Sklodowska Curie, for example, has pulled many scientists out of the mud, but they are not grateful enough to acknowledge it.
Kant, Schopenhauer, Hegel, Spencer, Emerson, and Bergson were philosophers, and were all lean and slender men. Lord Kelvin, Lister, Darwin, Curie, Francis Bacon, Michelson, Loeb, Burbank, and most of our other scientists are also of the thin, lean type.
