Research Programmes

The methodology of scientific research programmes, developed by Imre Lakatos, can help us to identify which theories are strong or weak. Applying this approach suggests that the secularization research programme is progressing, as Stolz argues. Some of the recent advances have been more successful than others, however. In particular, we have done better at understanding how secularization happens than why it happens.

The Middle Ages

Scientific research and a series of important archaeological discoveries in recent years have opened up new perspectives on the study of ancient glass. Glass production seems to have been organised on a hierarchical basis. The primary workshops, mainly concentrated on the Syro-Palestinian coast, prepared the raw material by fusing sand from the river Belus with natron from Egypt. The product was then sent in blocks to all secondary workshops, the organisation of which was less elaborate. Here work was limited to re-fusing material that had already been worked. The widespread commercial movement of raw glass from East to West seems to have only come to a halt in the 9th c., when the export of natron from Egypt stopped. Consequently, a different flux was used, which was incompatible with the oriental sand. The adoption of local raw materials in the place of natron meant that the management of the entire production cycle became gradually autonomous, at different speeds and in different ways, during the course of the Middle Ages.

Conversaziones were held this year on 24 May and 23 June. The practice of inviting guests to visit the rooms of the Society in order to meet the President and Fellows and to inspect a collection of scientific instruments and other objects, which had been brought together for the purpose of illustrating the most recent advances in scientific research, seems to have been introduced in 1849.

Major Progress

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.

If we make a set of measurements, such as narrow-band or multicolour photo-electric measurements, which are designed to improve a scheme of classification, and in particular if they are designed to extend the number of dimensions of classification, i.e. the number of classification parameters, then some important problems of analytical procedure arise. First, it is important not to reproduce the errors of the classification scheme which we are trying to improve. Second, when trying to extend the number of dimensions of classification we have little or nothing with which to test the validity of the new parameters.Problems similar to these have occurred in other areas of scientific research (notably psychology and education) and the branch of Statistics called Multivariate Analysis has been developed to deal with them. The techniques of this subject are largely unknown to astronomers, but, if carefully applied, they should at the very least ensure that the astronomer gets the maximum amount of information out of his data and does not waste his time looking for information which is not there. More optimistically, these techniques are potentially capable of indicating the number of classification parameters necessary and giving specific formulas for computing them, as well as pinpointing those particular measurements which are most crucial for determining the classification parameters.
