PERSPECTIVE Steno, Targioni and the Two Forerunners
dominici:ARGENTI 11/01/2010 11:40 Pagina 101 Journal of Mediterranean Earth Sciences 1 (2009), 101-110 doi:10.3304/JMES.2009.011 Journal of Mediterranean Earth Sciences JME S PERSPECTIVE Steno, Targioni and the two forerunners Stefano Dominici* Museo di Storia Naturale, Sezione di Geologia e Paleontologia, Università degli Studi di Firenze Via La Pira, 4 - 50121 Firenze, Italy ABSTRACT - The brief and enigmatic Forerunner written by Nicholas Steno after a two-year residence in Tuscany (1667- 1668) contains several basic intuitions of earth sciences. His work influenced contemporary natural philosophers through Europe, but was seemingly forgotten in the course of the next century. Only in Florence the naturalist and polymath Giovanni Targioni Tozzetti undertook a geological study of Tuscany and tested the validity of Steno’s hypothesis on the origin of mountains and hills. In relevant passages of his Travels (1751-1754), Targioni expressed a substantial agreement with Steno’s reconstruction, therefore planning a modernized version of Steno’s theory of the earth, which he published in his own Forerunner (1754). In this work he sets the agenda for the new disciplines of physical chorography and topography, wishing to complete their application to Tuscany in his own lifetime, so that Tuscany could be presented as a template of the earth. His fame as author of Travels and owner of one of the best natural history museums of Europe reached many savants who visited him and learned the results of his fieldwork and his geotheory. Some of the people who met with Targioni have influenced the development of geology, and important aspects of his ideas can be found in their writings. -

Discoveries and inventions are sometimes the product of the genius or of the intelligent in- dustry of a single person and leave his hand in a perfect state, as was the case with the ba- rometer invented by Torricelli, but more often the seed of the invention is planted by one, cultivated by others, and the fruit is gathered only after slow growth by some one who ig- nores the original sower. In studying the ori- gin and tracing the history of certain discov- eries of scientific and practical value one is often perplexed by encountering several claim- ants for priority, this is partly due to the cir- " cumstance that coincidence of independent thought is often the cause of two or more per- " sons reaching the same result about the same time and to the effort of each nation ; partly to secure for its own people credit and renown. Again, the origin of a prime invention is some- i 6 EVOLUTION OF THE THERMOMETER, times obscured by the failure of the discoverer to claim definitely the product of his inspira- tion owing to the fact that he himself failed to appreciate its high importance and its utility. -
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. -
A Saint in the History of Cardiology
Arch Cardiol Mex. 2014;84(1):47---50 www.elsevier.com.mx SPECIAL ARTICLE A saint in the history of Cardiology Alfredo de Micheli ∗, Raúl Izaguirre Ávila National Institute of Cardiology Ignacio Chavez, Tlalpan, DF, Mexico Received 19 December 2012; accepted 22 January 2013 KEYWORDS Abstract Niels Stensen (1638---1686) was born in Copenhagen. He took courses in medicine Niels Stensen; at the local university under the guidance of Professor Thomas Bartholin and later at Leiden Anatomy; under the tutelage of Franz de la Boë (Sylvius). While in Holland, he discovered the existence of Physiology; the parotid duct, which was named Stensen’s duct or stenonian duct (after his Latinized name Muscular fibers; Nicolaus Stenon). He also described the structural and functional characteristics of peripheral Heart muscles and myocardium. He demonstrated that muscular contraction could be elicited by appropriate nerve stimulation and by direct stimulation of the muscle itself and that during contraction the latter does not increase in volume. Toward the end of 1664, the Academic Senate of the University of Leiden awarded him the doctor in medicine title. Later, in Florence, he was admitted as a corresponding member in the Academia del Cimento (Experimental Academy) and collaborated with the Tuscan physician Francesco Redi in studies relating to viviparous development. In the Tuscan capital, he converted from Lutheranism to Catholicism and was shortly afterwards ordained in the clergy. After a few years, he was appointed apostolic vicar in northern Germany and died in the small town of Schwerin, capital of the Duchy of Mecklenburg- Schwerin on November 25, 1686. -

Jan Kochanowski University Press This is a contribution from Token: A Journal of English Linguistics Volume 8/2019. Edited by John G. Newman, Marina Dossena and Sylwester Łodej. Special Editors for volume 8: Giovanni Iamartino and Irma Taavitsainen. © 2019 Jan Kochanowski University Press. Token: A Journal of English Linguistics 8, 2019 Italy and the Royal Society: Medical papers in the early Philosophical Transactions Lucia Berti University of Milan ABSTRACT During the first years of the Royal Society’s existence, a whole network of natural philosophical exchanges was set up between the Fellows and foreign gentlemen interested in the study of nature. From the exchanges with Italy, medicine appears to be one of the major topics of interest; and a series of medical papers based on Italian researches appear in the Society’s journal, the Philosophical Transactions (PT). This article is a linguistic and socio-historical analysis of 25 medical papers published in the PT in the first fifty years of its existence. The selected articles were either translations of Italian writings or reports of Italian research. The purpose of the study is: (1) to illustrate from a linguistic and socio-cultural point of view the nature of Italian medical contributions to the early PT; and (2) to investigate Anglo-Italian relations through the Royal Society’s medical interaction with Italians by analysing the PT articles and further contextual resources from a critical perspective. Keywords: Anglo-Italian relations, medical writing, Philosophical Transactions, Royal Society, seventeenth century. And your own intelligence will spur you on, without the urging of others, to inform yourself about these matters; in the same way you will be led, without doubt, to encourage all the keen minds of Italy to employ their talents in advancing the sciences and the arts by observations and experiments faithfully and diligently performed. -

Physics in Italy from 1870 to 1940 Antonio Casella, Silvana Galdabini
Physics in Italy from 1870 to 1940 Antonio Casella, Silvana Galdabini, Giuseppe Giuliani, Paolantonio Marazzini Gruppo Nazionale di Storia della Fisica del CNR, Unit`adi Pavia The fact that, as you know, this Conference will be followed by another one dedicated to a century of physics in Italy, has induced us to present here firstly a general overview of our research, then a brief outline af our most recent findings. Our research started in the fall of 1983 as a project limited to the pre- history of solid state physics in Italy. It began with a study of the institutional context of physical research between 1870 and 1940, with particular attention given to the four decades of our century. The analisys of scientific production in fields that would have become parts of today solid state physics has not been completed. We have studied in some detail only five topics: magnetic properties • galvanomagnetic effects • elastic properties • photoelectric effect and photoconductivity • electric conductivity. • However it must be stressed that these five topics cover about 75% of the entire production concerning `solid state'. Moreover, it is in these fields that Italian contribution has been, for several reasons, more interesting. The results of this first effort have been described and discussed, among others, in the publications reported in footnotes.1;2;3;4 The study of the pre-history of solid state physics has found a kind of accomplishment in the organisation of a meeting on `The origins of solid state physics in Italy: 1945-1960', held in Pavia in 1987. Apart from five lectures given by historians, the contributions came from physicists who contributed to the development of this field in Italy (16) and abroad (3). -
