There seems, therefore, no necessity to regard the 'pre-formation' theory of evolution, rather than the 'dispersive theory, as essential to Positivism. Recent Developments in European Thought This shortness in the latter cases is due to the small dispersive power of the three minerals mentioned. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public If the refracting angle of the prism is small, then the ratio of the dispersion to the mean deviation of the two rays is the dispersive power of the material of the prism.

Half-hours with the Telescope Being a Popular Guide to the Use of the Telescope as a Means of Amusement and Instruction. If this instance be taken as typical of the process of evolution in general, then the course of evolution is not, so to speak, linear or rectilinear, but—to use M. Bergson's word—'dispersive'. Recent Developments in European Thought For thought has become dispersive, and the centrifugal forces of the human mind, among those who think seriously, have for the time become dominant and supreme. On Compromise The second of these two expressions is generally given as the definition of dispersive power.

The Gutenberg Webster's Unabridged Dictionary Section F, G and H Buddhism, however, on the 'dispersive' view of the evolution of religion, is not the only radiation from the common centre, of which we have to take account, in addition to fetishism, polytheism, and monotheism. Recent Developments in European Thought Therefore f1 and f2 must have different algebraic signs, or the system must be composed of a collective and a dispersive lens. The Project Gutenberg Encyclopedia Volume 1 of 28 Mei Yao-ch`en says it is "a position not far enough advanced to be called 'facile,' and not near enough to home to be 'dispersive,' but something between the two."

Springhaven : a Tale of the Great War It is merely a destructive and dispersive instead of a constructive and accumulative industrialism. War and the future: Italy, France and Britain at war It seems equally capable of being fitted in to the 'dispersive' theory, and of being regarded as an emanation or radiation proceeding direct from the human heart. Recent Developments in European Thought Newton failed to perceive the existence of media of different dispersive powers required by achromatism; consequently he constructed large reflectors instead of refractors. The Project Gutenberg Encyclopedia Volume 1 of 28 For an achromatic dispersive lens the converse must be adopted. The Project Gutenberg Encyclopedia Volume 1 of 28 |
