Restauro in Cina, il caso delle pagode medievali nel XX secolo
No full textLa tesi rilegge le esperienze del restauro in Cina nel XX secolo con l’occhio cinese e con una conoscenza della cultura italiana in questo settore, per approfondire i temi del dibattito sulle diverse modalità di approccio tra l’Italia e la Cina nella conservazione dei Beni Architettonici.
OBIETTIVI
Sono state selezionate come oggetti di studio due pagode quasi coeve, collocate nell’odierna Su-zhou: la Pagoda Hu-qiu, la cui costruzione è iniziata nel 959 e quella Rui-guang, costruita a partire dal 1004. La prima è stata restaurata negli anni ’50 e successivamente negli anni ’80, con l’obiettivo di “preservare la condizione attuale”. La seconda è stata restaurata negli anni ’80, con l’intento di “restituire le presunte condizioni originarie”. Per la Pagoda Hu-qiu la finalità è stata raggiunta attraverso il consolidamento statico e la conservazione della forma attuale, mentre per quella Rui-guang attraverso il “ripristino” soprattutto delle strutture lignee esterne (tetti-cornicione, balconi, ...).
FASI DELLA RICERCA
La ricerca si articola in tre parti:
- Nella prima parte si è tracciata una breve introduzione dello sviluppo storico e tipologico delle pagode cinese, con l’attenzione posta sul tipo della pagoda a padiglioni con piani sovrapposti a cui appartengono i due monumenti interessati alla ricerca.
- Nella seconda parte di questa tesi la ricerca è consistita nell’esaminare e sistemare i documenti esistenti e le conoscenze accumulate per secoli, confrontando i dati tra loro e cercando i riscontri tra questi e le nuove conoscenze maturate all’interno del mondo scientifico, anche se queste sono frammentarie e insufficienti. Dallo studio dei testi antichi, sono state sistemate le diverse lacune e ambiguità inizialmente rintracciate, per “ricostruire” una storia ancora lacunosa ma verificabile. Successivamente è stato effettuato uno studio storico-analitico che presenta le radici culturali cinesi diverse da quelle italiane con lo scopo di comprendere il Genius Loci della “Collina Hu-qiu”.
- La terza parte è stata indirizzata allo studio dell’aspetto tecnico degli interventi effettuati sulle realtà architettoniche in esame al fine di presentare le condizioni e lo sviluppo della tecnologia adottata nel restauro dei monumenti in Cina. Infatti, confrontando la situazione italiana con quella cinese, si nota come non sia stato maturato il percorso metodologico dalla manutenzione al restauro modernamente inteso. Attraverso le analisi delle riflessioni teoriche alla base degli interventi, è stato così possibile ripercorrere una parte importante della storia del pensiero e della attuazione operativa del restauro in Cina nell’ultimo secolo, dalla nascita della Società per la Ricerca sull’Architettura cinese dal 1930 in poi
Seki Takakazu's Correction of the Solution of Yang Hui Suanfa (Study of the History of Mathematics 2022)
No full textIn May 1673, Seki Takakzu completed a revised manuscript of “Yang Hui suanfa”. Seki corrected a proof in “Yang Hui suanfa”. Yang Hui claimed to have corrected the errors in three of the solutions of “Wucao suanjing”, but in the third and final solution, he had no choice but to show a non-mathematical solution: he drew a reduced drawing to find the required length and then measured it to find the actual length. Seki showed the correct length in his manuscript. Although Seki did not describe his argument for finding the length, his argument can be easily deduced. To do so, a simultaneous equation consisting of two unknowns had to be solved, and one of the unknowns had to be eliminated. This suggests that the “Yang Hui suanfa” problem was one of his first possible encounters with a problem that required many unknowns for its solution. In the manuscript, Seki gave a solution that is quite different from the solution given by Yang Hui. Again, he does not say how he obtained that solution. In this solution, it is not necessary to find the length of the line segment as Yang Hui did, but only to find the area from the three sides of a triangle. This is substantially described in Problem 19 of the “Daijutsu bengi no ho”. This formula for area is essentially the same as Heron's formula. However, it is doubtful that Seki found this solution immediately after solving the quadratic equation of the line segment numerically to find the true length. In this note, I will discuss another possibility for Seki's argument: the possibility that he used the root formula for a special type of quadratic equations. This formula could have been obtained by Seki combining Problem 14 in the second volume of “Tianmu bilei chengchu jiefa” of “Yang Hui suanfa” and Problem 8 in the final chapter of “Suanxue qimeng.
A Study of the Korean Edition of Yang Hui Suanfa : The Woodblock Version Discovered in Kogryo University (The study of the history of mathematics 2016)
No full text"The study of the history of mathematics 2016". August 29～September 1, 2016. edited by Shigeru Jochi. The papers presented in this volume of RIMS Kôkyûroku Bessatsu are in final form and refereed.The Yang Hui Suanfa (YHS) had a new direction of the mathematics in Eastern Asia, that is to say, speedy calculations for commercial trade, therefore it became the textbook in the Yi dynasty (1392-1910) in Korea. It was said that there were few sets of YHS in Korea, however the author found a Korean woodblock printing book at the Kogryo University in 2015. It has the same contents and mistakes as other Korean editions. We found the 8th set of YHS in the world, in the other words, the YHS was not so rear book in Korea, was quite popular for the mathematicians in Korea and Japan. Yang Hui studied higher degree equations quite deeply, he discovered that a quadratic equation has two solutions, that is to say, the new solving method of the "Fanjifa" in 1275. Although Jia Xian already discovered Jia Xian, Yang Hui and Pascal's triangle at the 11th century, but Yang Hui said it was "old" method for solving higher degree equations. Therefore I conclude that the "pre-modern age" would start from the 13th century, not the 16th century in Eastern Asia
