From a scientific perspective, we argue that the renaming conflates the redshift/distance relation of the spiral nebulae with a universal law of cosmic expansion derived from the general theory of relativity. We note that the first of these phenomena is merely one manifestation of the second, an important distinction that might be relevant to contemporary puzzles concerning the current rate of cosmic expansion.

These findings influenced M?r?cineanu’s subsequent independent research, and later compelled her to claim priority for the discovery of artificial radioactivity. The present analysis of these data, performed with the least-squares method, certifies the outstanding accuracy of the experimental measurements by providing values with good agreement between the different series of measurements and an average value that is close to the currently adopted half-life value of this isotope.

Verbiest was called upon in 1660 to assist Schall in his project of reforming the Chinese traditional calendar. The political situation changed in 1661, with the Empire ruled by a regency hostile to the Jesuits, as were most of the mandarins at the observatory. This was the difficult context of the famous dispute between Yang Guangxian, Wu Mingxuan, and the two Jesuit mathematicians to compare the merits of Western and Chinese astronomy, which lasted from 1664 to 1669.

In 1644, the Qing government appointed the Germany Jesuit missionary Johann Adam Schall von Bell head of the Bureau of Astronomy, placing him in charge of reforming the Chinese calendar. In the traditional calendar, in addition to dates based on astronomical calculation, there were annotations attached to each day, which included auspicious and inauspicious days with advice on what to do in daily life according to Chinese astrology. Schall reformed the time arrangements with Western astronomical methods. However, he hoped to go further and proposed to change the annotations on the basis of Western natural astrology. Why did Schall choose to import Western astrology into Chinese astronomy, rather than simply sticking to astronomy? I argue that his views were influenced by both the attitudes of the Roman Catholic Church and the Aristotelianism scholarly tradition. The underlying tensions between Europe and China did not involve conflicts between science and pseudoscience, but between different religious beliefs, as well as different natural philosophies and cosmologies. The encounter of two radically different cultural traditions reflected the complicated relationship between science and belief from a global point of view.</p>","PeriodicalId":727,"journal":{"name":"Physics in Perspective","volume":"22 2","pages":"110 - 126"},"PeriodicalIF":0.4,"publicationDate":"2020-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00016-020-00255-z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4874766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
