Gianantonio Tadini is the little known protagonist in an important experiment carried out in Bergamo between 1794 and 1795. Based on the measurement of the deviation of a falling body, the experiment owes much to the one that was conducted by Giambattista Guglielmini in Bologna in 1791, which aimed at demonstrating Earth’s rotation. Tadini’s experimental work represents the most successful attempt carried out before the 19th century, and it led to the first correct formulation of deviation’s measurement. In spite of (...) this, it is not well represented in the general literature on the history of experiments intended to show diurnal Earth’s motion.1 The discovery of Tadini’s diary of experiments as well as some notes and a part of his correspondence – preserved as manuscripts in the Angelo Mai municipal library in Bergamo – allows us now to reconstruct the history of Tadini’s experiment and of his reasoning about Guglielmini’s work. In this paper, I describe the genesis and the development of Tadini’s experiment, clarify the role played by the different personalities involved and set these trials against the background of the widest history of proofs on diurnal Earth’s rotation carried out in Europe in those years.

The enormous increasing of connections between people and the noteworthy enlargement of domains and methods in sciences have augmented extraordinarily the cardinality of the set of meaningful human symbols. We know that complexity is always on the way to become complication, i.e. a non-tractable topic. For this reason scholars engage themselves more and more in attempting to tame plurality and chaos. In this book distinguished scientists, philosophers and historians of science reflect on the topic from a multidisciplinary point of view. (...) Is it possible to dominate complexity through reductionism? Are there other conceptual instruments useful to take account of complexity? What is complexity in biology, mathematics, physics and philosophy of mind? These are some of the questions which are faced in this volume. (shrink)

Information on the origins of the Accademia del Cimento is extremely limited. Almost all of the surviving correspondence relating to the year before the Academy began its activities variously concerns print culture. Lists of books (read, studied, purchased, and researched), handwritten notes on old or new publications, vernacular translations of edited passages, and inquiries about new works punctuate the archive. The study of these lists and of the relationship between reading practices and ones related to annotation and knowledge production leads (...) to a reinterpretation of certain aspects of the Accademia del Cimento, suggesting the pursuit of a more flexible agenda.Through the analysis of some book lists, this contribution aims to shed light on the presence in Florence of interconnected groups of scholars, common epistemic practices, and a kind of methodological unity centred on the sharing of materials and agreement concerning the need to subject theories to experimental verification.
