Particularly in the 14th and 15th centuries, the city was the theatre of a true Renaissance of science. Archimedes was the legendary figure of reference for generations of mechanical engineers: Filippo Brunelleschi (1377-1446), Mariano di Jacopo, known as Taccola (1382 - 1453 c.), Francesco di Giorgio Martini (1439-1501) and Leonardo da Vinci (1452-1519) remain inextricably linked to the invention of astonishing machines – for warfare, hydraulics, construction 16 sites and entertainment – that anticipated the progress in mechanical science achieved in the following century by Guidobaldo del Monte (1545-1607) and Galileo Galilei (1564-1642). The myth of Archimedes favoured the affirmation of two new professional figures: the artist-engineer, not a simple ‘mechanic’, but an authority in ancient technology, author, and partner in a dialogue between literates and humanists; and the engineer-scientist, who operated in the major European universities in the sixteenth century, and contributed to make the ars mechanica a mathematical discipline. Florentines as Paolo dal Pozzo Toscanelli (1397-1482) and Amerigo Vespucci (1454-1512) contributed to. With the discovery of the New World, geographic works were compiled to update the information based on Ptolemaic science. Humanists’ libraries abounded in geographic books and many sumptuous, costly codices were produced by Florentine workshops in the 15th century. Lorenzo the Magnificent (1449-1492) owned numerous geographical maps and a superb codex of the Geografia ‘painted’ by Piero del Massaio (15th century), which then passed into the hands of Cosimo I (1519-1574). In the age of Medici, Florence was an important centre of scientific research and collections. This aspect of the Florentine culture is generally less known, but science and scientific collections were a consistent part of the story of the city. At the same time, collecting scientific instruments was MUSEOLOGIA & INTERDISCIPLINARIDADE Vol.5, nº9, Jan./ Jun. de 2016 Jan./ Jun. nº9, Vol.5, MUSEOLOGIA & INTERDISCIPLINARIDADE an important component of the political strategies of the Florentine Grand Dukes, convinced that scientific knowledge and technological control over nature would confer solidity and prestige on political power. From Cosimo I (1519-1574) to Cosimo III (1642-1723), the Medici Grand Dukes bestowed their patronage and commissions on generations of engineers and scientists, forming a collection of mathematical and astronomical instruments, scientific models and natural products, displayed alongside the more famous collections of art in the Galleria degli Uffizi, in Palazzo Pitti, and around the city of Florence and other places in Tuscany. This superb collection, still existing, is an expression not only of the ‘taste’ of the times but also of the multifaceted interests that the Grand Dukes focused their attention on. The Florentine scientific museums preserve it: for instance, scientific instruments are now preserved in the Museo Galileo, stuffed animals in ‘La Specola’, herbaria in Museum of Botany and so on (CAMEROTA, MINIATI, 2008)2.

Sul tema del tempo e del suo rapporto con l’intemporalità della sfera logica, cioè del nesso tra differenza vissuta e identità pensata, si giocò la tragica ambiguità dello spirito borghese negli ultimi decenni del sec. XIX e nei primi del XX, proprio mentre nella cultura dell’Occidente la coscienza della storicità dell’esistere si espri- meva nella egemonia dell’intonazione storicistica. La razionalità tecnologico-economica e la sua esaltante prospettiva di un illimi- tato sviluppo del potere umano sulla natura (cui corrispondeva, per lo più incon- fessata, l’arrogante sicurezza dell’illimitata conservazione del dominio sui molti da parte di quei pochi che il potere sulla natura effettivamente detengono) estesero la pretesa dell’oggettività conoscitiva, espressa nell’intemporalità degli enunciati “scientifici”, anche agl’“ideali” del mondo borghese, assunti nella loro più recente versione, e proiettarono nel progettato futuro la pretesa stabilità, sempre meno ri- conoscibile nel passato prossimo.

  • On the Isochronism of Galilei's Horologium
    IFToMM Workshop on History of MMS – Palermo 2013 On the isochronism of Galilei's horologium Francesco Sorge, Marco Cammalleri, Giuseppe Genchi DICGIM, Università di Palermo, [email protected], [email protected], [email protected] Abstract − Measuring the passage of time has always fascinated the humankind throughout the centuries. It is amazing how the general architecture of clocks has remained almost unchanged in practice to date from the Middle Ages. However, the foremost mechanical developments in clock-making date from the seventeenth century, when the discovery of the isochronism laws of pendular motion by Galilei and Huygens permitted a higher degree of accuracy in the time measure. Keywords: Time Measure, Pendulum, Isochronism Brief Survey on the Art of Clock-Making The first elements of temporal and spatial cognition among the primitive societies were associated with the course of natural events. In practice, the starry heaven played the role of the first huge clock of mankind. According to the philosopher Macrobius (4 th century), even the Latin term hora derives, through the Greek word ‘ώρα , from an Egyptian hieroglyph to be pronounced Heru or Horu , which was Latinized into Horus and was the name of the Egyptian deity of the sun and the sky, who was the son of Osiris and was often represented as a hawk, prince of the sky. Later on, the measure of time began to assume a rudimentary technical connotation and to benefit from the use of more or less ingenious devices. Various kinds of clocks developed to relatively high levels of accuracy through the Egyptian, Assyrian, Greek and Roman civilizations.

  • A Phenomenology of Galileo's Experiments with Pendulums
    BJHS, Page 1 of 35. f British Society for the History of Science 2009 doi:10.1017/S0007087409990033 A phenomenology of Galileo’s experiments with pendulums PAOLO PALMIERI* Abstract. The paper reports new findings about Galileo’s experiments with pendulums and discusses their significance in the context of Galileo’s writings. The methodology is based on a phenomenological approach to Galileo’s experiments, supported by computer modelling and close analysis of extant textual evidence. This methodology has allowed the author to shed light on some puzzles that Galileo’s experiments have created for scholars. The pendulum was crucial throughout Galileo’s career. Its properties, with which he was fascinated from very early in his career, especially concern time. A 1602 letter is the earliest surviving document in which Galileo discusses the hypothesis of pendulum isochronism.1 In this letter Galileo claims that all pendulums are isochronous, and that he has long been trying to demonstrate isochronism mechanically, but that so far he has been unable to succeed. From 1602 onwards Galileo referred to pendulum isochronism as an admirable property but failed to demonstrate it. The pendulum is the most open-ended of Galileo’s artefacts. After working on my reconstructed pendulums for some time, I became convinced that the pendulum had the potential to allow Galileo to break new ground. But I also realized that its elusive nature sometimes threatened to undermine the progress Galileo was making on other fronts. It is this ambivalent nature that, I thought, might prove invaluable in trying to understand crucial aspects of Galileo’s innovative methodology.
