Il carteggio Gianfrancesco Malfatti - Giordano Riccati
No full textGianfrancesco Malfatti (1731-1807), one of Vincenzo Riccati’s brightest students during his teaching years in Bologna, following his master’s death begun a significant scientific correspondence with Vincenzo’s younger brother Giordano (1709-1790), an eclectic scholar and author of a treatise on acoustics. The correspondence, which is published here in full, is kept in the Public Library Vincenzo Joppi of Udine, and cover a wide time span from October 1777 to May 1789, a few months before Giordano’s death. It consists of 125 letters, 61 by Malfatti and 64 by Riccati, the latters being copies made by Riccati himself. The topics discussed range from different areas of mathematics: logarithms of negative numbers, calculus of variations, probability and combinatorics, mathematical physics, in particular mechanics and acoustics
Verbali dell'Accademia medico - chirurgica per l'anno 1849
No full textSi tratta della trascrizione dei verbali dell'accademia medico-chirurgica di Ferrara per l'anno 1849 in cui fu creata la Repubblica Romana. Si delineano due atteggiamenti differenti tra gli accademici, da una parte la collaborazione alle iniziative della Repubblica, dall'altra un tirarsi da parte. Emergono figure di medici riformatori impegnati nel sociale come Lionello Poletti, Carlo Grillenzoni, Luigi Bosi, che assumeranno cariche di responsabilità nell'Accademia e nell'Università di Ferrara dopo l'unificazione nazionale

I matematici e le nuove linee per il Reno (1692-1772)
No full textIl problema della regolazione del corso del fiume Reno nella pianura tra Bologna e Ferrara, tornato di grande attualità dopo gli eventi sismici del maggio 2012, è stato lungamente dibattuto nel corso dei passati secoli. In questo lavoro viene fornito un quadro delle principali vicende che hanno caratterizzato il corso del Reno tra il 1692 ed il 1772, mettendo in luce l’apporto fornito dai più importanti matematici italiani del tempo nella vicenda. Gli estremi temporali coincidono con quelli di due importanti visite alle acque, la prima, nota come Visita D’Adda Barberini, dal nome dei due cardinali che la sovrintesero, vide l’attiva partecipazione del matematico bolognese Domenico Guglielmini. Alla seconda, conclusasi nel 1772 e ricordata come Visita dei tre periti, presero parte tre importanti scienziati, tra i quali spicca quello del matematico e idrostatico milanese Giovanni Antonio Lecchi. Particolare attenzione è stata posta sulla cosiddetta Visita Conti (1761-62), alla quale presero parte i matematici Gabriele Manfredi, bolognese, Teodoro Bonati, ferrarese, oltre al milanese Paolo Frisi e al toscano Leonardo Ximenes
R. G. Boscovich (1711-1787). Le prime ricerche sul moto delle acque
No full textVengono presentati due dei primi contributi di Ruggiero Giuseppe Boscovich alla scienza delle acque. Si tratta di due perizie redatte nel 1752, mentre Boscovich si trovava in viaggio nei territori dello Stato Pontificio per la misura dell’arco di meridiano. La prima memoria è relativa alla sistemazione del corso del Tevere a nord di Roma, nel territorio compreso tra Ponte Felice ed il Fosso di Rustica, nei pressi di Magliano Sabina. La seconda riguarda la regolazione delle valli di Comacchio e in particolare il loro sbocco in mare rappresentato dal porto di Magnavacca, posto sull’Adriatico tra le foci dei fiumi Reno e Volano. In appendice è riportata la trascrizione delle due memorie. Esse documentano l’attività di Boscovich nella regolazione delle acque prima degli impegni assunti a Lucca e nel Milanese
La tradizione galileiana nei progetti editoriali della stamperia granducale di Firenze (1713-1723)
No full textThis essay will examine the first collection on the motion of waters, produced by the followers of Galileo, which was published in Florence in 1723, by focusing on the cultural background that lays behind the publication of this important work. The three volumes were prepared by Tommaso Buonaventuri, who served as director and editor of the printing works of the Grand Duchy of Tuscany from 1713 to 1723. Among his collaborators on this project were the men of letters Giovanni Gaetano Bottari and Benedetto Bresciani, and the mathematician Guido Grandi. Buonaventuri played a leading role in intellectual circles during the first two decades of the eighteenth century, promoting many initiatives, such as the publication of the Lezioni Torricelliane, by Evangelista Torricelli and a new edition of Galileo's Opere. The collection of essays on the motion of waters belongs to a branch of research that directly derived from the Galilean tradition and will be examined in this light. The first volume contains works by Galileo himself, his former students Vincenzo Viviani, Benedetto Castelli, and others who were directly inspired by their studies and by their approach to doing science, including Giovanni Alfonso Borelli, Geminiano Montanari and Famiano Michelini. The second volume contains Guido Grandi's hydraulic works, while the third volume is almost entirely devoted to hydraulic papers about the river Reno
Le raccolte italiane sul moto delle acque
No full textSi tratta dell'esame di cinque raccolte sul moto delle acque, pubblicate in Italia tra il 1723 ed il 1845: due edizioni pubblicate a Firenze, la prima in tre e la seconda in nove volumi, una edizione stampata a Parma in sette volumi e due edizioni bolognesi, la prima in dieci e la seconda in sette volumi.
Le cinque raccolte vengono esaminate e confrontate; esse contengono risultati sia teorici che pratici sulla scienza delle acque. Tra gli autori figurano i principali esponenti della scuola galileiana, Benedetto Castelli, Vincenzo Viviani, Famiano Michelini, oltre ad altri importanti matematici, quali Guido Grandi, Eustachio Manfredi, Domenico Guglielmini e Bernardino Zendrini.This work deals with the examination of five collections on the motion of water that were printed in Italy between 1723 and 1845. There were two Florentine editions, one published in three volumes in 1723 and the other published in nine volumes between 1765 and 1774. Another edition was edited by the Jesuit Jacopo Belgrado in Parma in seven volumes between 1766 and 1768. Bologna produced two editions, both of which were edited by Francesco Cardinali in the first half of 19th century. The first one was printed between 1821 and 1826 in ten volumes, while the second one was printed between 1823 and 1845 in seven volumes. Both Florentine editions were printed in the grand-ducal print shop, whose director and reviser from 1713 to 1723 was Tommaso Buonaventuri. Together with the mathematician Guido Grandi, Buonaventuri was the main creator of the first edition of the collection. In this work, the five collections on the motion of water have been examined and compared. They contain both theoretical and practical contributions to the science of waters. Many authors appear in different editions, such as important exponents of the Galilean school as Benedetto Castelli, Vincenzo Viviani, Famiano Michelini. The works of other important mathematicians are in these collections, like Guido Grandi, Domenico Guglielmini, Eustachio Manfredi
Applied Mathematics in Boscovich’s Papers
No full textFrom 1742, the Jesuit R. G. Boscovich began to undertake work as consultant on applied mathematics on behalf of the Papal State and of the principle Italian courts.
In his first public office, Boscovich was required to give his opinion on the stability of St. Peter’s dome in Rome. Many papers on applied mathematics, especially hydraulics, followed this first consultation on an architectural work. In 1750 he was commissioned to measure the meridian between Rome and Rimini. Boscovich travelled to the lands of the Papal State with Father Christopher Maire, cartographer and astronomer. The journey took place between October 1750 and November 1752. In the same years, Boscovich was asked for his first works on the science of waters: an examination of the Fiumicino harbour near Rome, the regulation of the course of the Tiber, and the access to the Valleys of Comacchio.
The science of waters in the 18th century was a subject that still lacked clear rules, and the figure of an engineer to deal with the regulation of the rivers did not exist, so mathematicians were called in as experts in hydraulics. In this field Boscovich displayed all his talent. He wrote reports on the regulation of some rivers (the Tiber, Po, Adige) and streams, the reclamation of extensive marshlands (the Pontine marshes in Latium, the lake of Bientina in Tuscany), but his main contributions concerned the settlement of harbours placed at the river mouth (Fiumicino, Magnavacca, Rimini, Savona).
From the second half of the 18th century Boscovich addressed his studies to applied mathematics, astronomy, optics and hydraulics. He collected his work on optics and astronomy in the Opera pertinentia ad opticam et astronomiam (1785), but was unable to make a collection of all his papers on hydraulics before he died
Idrodinamica e idraulica. Le raccolte sul moto delle acque. La questione del Reno
No full textThe aim of this thesis is to illustrate the role of mathematicians in the history of hydraulics in Italy
in the 18th century by focusing on two aspects.
The first aspect is more general and deals with the main contributions of Italian mathematicians to
the collections on the motion of water that were published in Italy in five editions between the 18th
and the first half of the 19th century in Florence, Parma and Bologna. The second aspect is more
specific and deals with the problem of the regulation of the river Reno.
The first part of the thesis is dedicated to an examination of five collections on the motion of water
that were printed in Italy between 1723 and 1845. There were two Florentine editions, one
published in three volumes in 1723 and the other published in nine volumes between 1765 and
1774. Another edition was edited by the Jesuit Jacopo Belgrado (1704-1789) in Parma in seven
volumes between 1766 and 1768. Bologna produced two editions, both of which were edited by
Francesco Cardinali (1776-1861) in the first half of 19th century. The first one was printed between
1821 and 1826 in ten volumes, while the second one was printed between 1823 and 1845 in seven
volumes. As these collections represent very difficult and expensive works, it is important to
identify not only the editors of them, but also the printers. In this PhD thesis the five collections on
the motion of water have been examined and compared. They contain both theoretical and practical
contributions to the science of waters, starting from the Hydrostatics by Archimedes. Many authors
appear in different editions, like the main exponents of the Galilean school: first of all Benedetto
Castelli, then Vincenzo Viviani and Famiano Michelini. The works of other important
mathematicians are in these collections, like Guido Grandi, Domenico Guglielmini, Eustachio
Manfredi. To facilitate consultation of and comparison between the five collections, a database has
been created and can be found at the end of the work (Tavole). It allows the user to research by
means of author, subject or collection.The prefaces of these five collections have been transcribed
and can be found in the appendix.
Many of these works share the same theme, i.e. the problem of the regulation of the river Reno, that
is connected with the second part of the thesis. Each collection on the water’s motion contains
papers on this subject.
The second part of the PhD thesis deals with the regulation of the river Reno in the middle of the
18th century and, in particular, with the visit of Cardinal Conti, that took place between 1761 and
1762. The Reno is an Italian river and before its deviation it was the main right tributary of the river
Po. This river had a very irregular path in the Po river plain between the provinces of Bologna,
Ferrara and Ravenna. In its lower course the Reno receives the water of numerous streams, some of
which are seasonal, that carries great quantities of stones and gravel. That’s why its floods were so
frequent and dangerous. From the 16th century on this problem became unacceptable and the
authorities whose job it was to deal with this damage decided to tackle the situation in a definitive
way. However, this was just the beginning of a long series of quarrels that involved the provinces of
Bologna, Ferrara and Ravenna. Many Italian mathematicians took part in this long debate. The first
chapter of the thesis involves a historical study of the sequences of the river Reno, regarding the
variations of its path and the main intervention in its regulation during the Medieval age (chapter
I.1), in the 15th and 16th centuries (chapter I.2), in the 17th century (chapter I.3) and in the first part
of the 18th century (chapter I.4). In chapters II, III and IV the main part of the thesis is developed.
The second chapter deals with projects for the Reno and debates between Bologna and Ferrara in
the period 1740 - 1760. It is divided into seven sections: Gabriele Manfredi as a mathematician
(chapter II.1), Manfredi’s project (chapter II.2), Manfredi’s scientific heritage (II.3), the Ferrarese
project by Bertaglia and Bonati (chapter II.4), Paolo Frisi ad a mathematician (chapter II.5), Frisi’s
project (chapter II.6), Fantoni’s project (chapter II.7). The third chapter is devoted to the so-called
“Visita Conti”, that took place between May 12th 1761 and July 5th 1762. All the issues related to
the “Visita Conti” are described in the third chapter: Tommaso Perelli as a mathematician (chapter
III.1), Tommaso Perelli and the visit of the cardinal Conti (chapter III.2), Perelli’s Relazione
(chapter III.3), Jacquier and Le Seur as mathematicians (chapter III.4), Jacquier’s and Le Seur’s
Parere (chapter III.5), the debate between Perelli and Jacquier (chapter III.6), Teodoro Bonati as a
mathematician (chapter III.7). The Visita Conti was not conclusive, so three other mathematicians
had to be consulted: the main one was the Jesuit Giovanni Antonio Lecchi (1702-1776), whose
project for the Reno was the definitive one. The fourth chapter is entirely dedicated to the figure of
Lecchi and to his plan for the settlement of the Reno: Lecchi as a mathematician (chapter IV.1), the
hydrodynamics and Boscovich (chapter IV.2), the three technicians (chapter IV.3), Lecchi’s plan
and its realization (chapter IV.4). The last chapter (chapter V) deals with some issues related to the
Reno’s path in the last year of the 18th century.
To complete the thesis three documents have been transcribed. Two of them are manuscripts: the
summary of the Visita Conti and twenty-two letters from Giovanni Antonio Lecchi to Ruggiero
Giuseppe Boscovich. The other one has been already published: it is the report of the Visita Conti
by Tommaso Perelli: Relazione sopra il regolamento delle acque delle tre province
