Page 1020 - ... systematic fashion how they achieved their aims. If the discovery of laws could be reduced to a set of formal rules, anyone who learnt the rules could discover laws. But there is no broad road to progress. Herein lies the most serious objection to much that has been written on the methods of science. There is no method, and it is because there is no method which can be expounded to all the world that science is a delight to those who possess the instincts which make methods unnecessary.
Page 837 - The object of the present paper is to show how it is possible to account theoretically for the main features of the phenomena of X-ray absorption and continuous X-ray emission discussed above.
Page 14 - Again it is obvious that even if it were possible to perceive by the senses that the sum of the angles of a triangle is equal to two right angles, we should still require a proof of this ; we should not (as some d fact remains that the object perceived is only one particular instance of the type.
Page 870 - The experiments described in this paper were carried out in order to provide more systematic evidence on the liquid-like behaviour of the growing film.
Page 492 - The evidence appears quite conclusive that every sample of silver iodide studied contained the cubic form; in a few cases none but the cubic structure was evident; in some, one or two faint lines were present which belonged only to the hexagonal form; while in most of the samples the hexagonal form predominated. No systematic study was made of the conditions governing the production of one crystal form or the other; the first sample showing the cubic form was prepared by precipitation; the other...
