Mathematics and explanation in astronomy and astrophysics

The purpose of this paper is to expound and clarify the mathematics and explanations commonly employed in certain notable areas of astronomy and astrophysics. The first section concentrates upon the mathematics employed to represent and understand stellar structure and evolution. The second section analyses two different explanations for the structure of spiral galaxies. 1 Stellar structure and...

Neural networks in astronomy.

In the last decade, the use of neural networks (NN) and of other soft computing methods has begun to spread also in the astronomical community which, due to the required accuracy of the measurements, is usually reluctant to use automatic tools to perform even the most common tasks of data reduction and data mining. The federation of heterogeneous large astronomical databases which is foreseen i...

Institutional Influences on Chinese Mathematics

Mathematics teacher stress in Chinese secondary schools

Since the 1970s studies on teacher stress have become numerous. However, most of the existing research has been the product of western countries. There have been a few studies conducted in the People’s Republic of China. This study aims to investigate the general level of Chinese math teachers’ stress, its main sources, and the coping methods. The questionnaire, which was used in Taiwan (Kyriac...

Absence of Geometric Models in Medieval Chinese Astronomy

In 718 A.D., Ch’üt’an Hsi-ta (Gautama Siddhārtha), an Indian astronomer who was appointed an“astronomer royal” in the T’ang court compiled a compendium of omens and divinations, called K’aiyüan Chan-ching, analogous to Varahamihira’s Br .hatsam. hita. The 104th volume of this work, Chiu-chih li (Nine Upholders Calendrical System) on astronomy was entirely based on the Indian astronomy of the 7t...
