Thomas S. Kuhn’s theory of normal science (NS), aside from being a provocative philosophical reconstruction of the relatively conservative phase of scientific research, contains useful ideas for systematic analysis of specific episodes in the history of science. Therefore, although the theory has been looked at from different angles since the first edition of The Structure of Scientific Revolutions (TSSR) was published in 1962, its detailed exploration of the cumulative phase of research in mature science is of abiding relevance in the (...) philosophy of science. This is because NS provides a compelling account of how and why members of scientific communities succeed, largely, to produce reliable knowledge about an incompletely known phenomenal world. Again, the theory elucidates special features of scientific research that differentiate it from other creative enterprises. In that regard, this paper reconstructs Arthur Compton’s research into x-ray scattering as a good instantiation of NS. Discussion of Compton’s convincing demonstration of the particulate properties of electromagnetic radiation within the framework of NS showcases the elucidatory power of Kuhn’s theory with respect to selected episodes in science, and corroborates the notion that the bulk of scientific work is a conservative puzzle-solving activity with the potential for precipitating scientific revolutions. To the best of my knowledge, this is the first time that Compton’s groundbreaking work on x-ray scattering has been analysed within the framework of Kuhn’s philosophy of science. (shrink)

This paper examines the impact of the introduction of Western (European) technical civilization on regional cultures in Nigeria, using Igboland in South-EasternNigeria as a test case. It begins with a discussion of some general features of Western technical civilization whose evolution has been profoundly influenced by technological advances in Europe and her cultural colonies in North America and elsewhere. Consequences of the contact between Western technical civilization and traditional Igbo culture are also examined. The paper concludes by discussing the challenging (...) problem of Africa’s contribution to technical civilization. (shrink)
