Leon Battista Alberti: Momus y De re aedificatoria, paralelismos, reciprocidades  [PDF]
Diego Suárez Quevedo
Pecia Complutense : Boletín de la Biblioteca Histórica de la Universidad Complutense de Madrid , 2009,
Abstract: Propone la lectura de Momus, del que la Biblioteca Marqués de Valdecilla conserva su edición princeps (Roma, 1520), en paralelo con el De re aedificatoria. Ambas obras tienen como tema de fondo la cultura arquitectónica y la ciudad. Pero, mientras que el De re aedificatoria es un tratado aséptico, en Momus Alberti se permite una libertad mucho mayor, con una carga crítica considerable y el despliegue de componentes personales
Alberti's letter counts  [PDF]
Bernard Ycart
Mathematics , 2012, DOI: 10.1093/llc/fqt034
Abstract: Four centuries before modern statistical linguistics was born, Leon Battista Alberti (1404--1472) compared the frequency of vowels in Latin poems and orations, making the first quantified observation of a stylistic difference ever. Using a corpus of 20 Latin texts (over 5 million letters), Alberti's observations are statistically assessed. Letter counts prove that poets used significantly more a's, e's, and y's, whereas orators used more of the other vowels. The sample sizes needed to justify the assertions are studied, and proved to be within reach for Alberti's scholarship.
Brunelleschi's mirror, Alberti's window, and Galileo's 'perspective tube'
Edgerton, Samuel Y.;
História, Ciências, Saúde-Manguinhos , 2006, DOI: 10.1590/S0104-59702006000500010
Abstract: this essay argues that the advent of linear perspective, ca. 1425, when filippo brunelleschi painted a small panel of the florentine baptistery by applying the geometric rules of optical mirror reflection, was more than just an artistic event. indeed, it subsequently had the most profound - and quite unanticipated - influence on the rise of modern science. surely, by 1609, galileo would not have understood what he saw when observing the moon through his newly invented optical telescope, then called the 'perspective tube,' had it not been for his training in perspective drawing. yet, brunelleschi's original dependence on the mirror two centuries earlier was intended not to reveal objective 'scientific' reality, but rather to reinforce christian spiritual 'reality.' in 1435-6, leon battista alberti, when codifying brunelleschi's perspective in his famous "treatise on painting," substituted a gridded window for brunelleschi's mirror, thus redirecting the purpose of perspective art away from revealing god's divine order as reflected on earth, to a more secular physical reality viewed directly in relation to human moral order.
Metric Currents and Alberti representations  [PDF]
Andrea Schioppa
Mathematics , 2014,
Abstract: We relate Ambrosio-Kirchheim metric currents to Alberti representations and Weaver derivations. In particular, given a metric current $T$, we show that if the module $\mathscr{X}(\|T\|)$ of Weaver derivations is finitely generated, then $T$ can be represented in terms of derivations; this extends previous results of Williams. Applications of this theory include an approximation of $1$-dimensional metric currents in terms of normal currents and the construction of Alberti representations in the directions of vector fields.
Derivations and Alberti representations  [PDF]
Andrea Schioppa
Mathematics , 2013,
Abstract: We relate generalized Lebesgue decompositions of measures along curve fragments ("Alberti representations") and Weaver derivations. This correspondence leads to a geometric characterization of the local norm on the Weaver cotangent bundle of a metric measure space $(X,\mu)$: the local norm of a form $df$ "sees" how fast $f$ grows on curve fragments "seen" by $\mu$. This implies a new characterization of differentiability spaces in terms of the $\mu$-a.e. equality of the local norm of $df$ and the local Lipschitz constant of $f$. As a consequence, the "Lip-lip" inequality of Keith must be an equality. We also provide dimensional bounds for the module of derivations in terms of the Assouad dimension of $X$.
Kopie der Kopie  [cached]
Naujokat, Anke
Archimaera , 2009, DOI: kopie der kopie
Abstract: In der Unterkirche San Rocco in Sansepolcro erhebt sich eine Kleinarchitektur, die laut Inschrift als Kopie des Jerusalemer Christusgrabes ausgewiesen ist. Statt sich an die architektonische Gestalt des nah stlichen Originals anzulehnen orientiert sie sich jedoch an einer lteren Heiliggrabkopie, dem Heiliggrabtempietto von Leon Battista Alberti in San Pancrazio, Florenz. Der Aufsatz untersucht, auf welche Weise die doppelte Kopie“ ihr Vorbild interpretiert und stellt überlegungen zu Motivation, Bedeutung und Autorschaft der Heiliggrabkopie von Sansepolcro an.
A taxonomic study of Chinese species of the alberti group of Metaphycus (Hymenoptera, Encyrtidae)  [cached]
Ying Wang,Chengde Li,Yanzhou Zhang
ZooKeys , 2013, DOI: 10.3897/zookeys.285.4142
Abstract: Ten alberti-group species of the genus Metaphycus Mercet from China are reviewed. Six species, M. dorsalis sp. n., M. chinensis sp. n., M. wui sp. n., M. stylatus sp. n., M. fusiscapus sp. n., and M. fusiformis sp. n. are described as new to science. Four known species from China are redescribed. A key to the females of the Chinese species is given and photomicrographs are provided to illustrate morphological characters of these species. All specimens, unless otherwise specified, are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing.
The World-System of Giovanni Battista Riccioli and the Phases of Venus and Mercury  [PDF]
Flavia Marcacci
Advances in Historical Studies (AHS) , 2015, DOI: 10.4236/ahs.2015.42011
Abstract: The Jesuit astronomer Giovanni Battista Riccioli (1598-1671) proposed an original astronomical system as an intermediate solution between the Copernican and the Ptolemaic systems. Many scholars describe his system as “geocentric”, and so does Riccioli. He uses the Tychonic solution by adding a lot of differences, for instance, the order of the orbits and the movement of Jupiter and Mars. In his astronomical work, Riccioli is rigorous and serious and offers a great quantity of observational data. The analysis of these results is crucial to understand the evolution of the Copernican question during the first half of the XVII century. The article will look at some general lines of Riccioli’s system, to understand how an astronomer of the XVII century really worked and to understand which problems the Copernican system could not resolve. Finally, I will try to consider some philosophical implications of this historical case.

Abstract: El Barómetro indusrial LEON 50 es un trabajo de investigación que tiene como objetivo esencial identificar características patrimoniales, financieras y económicas de una muestra de empresas que actúan dentro de la industria leonesa. El soporte de este estudio empírico es la información contable anual auditada que depositan en el Registro Mercantil las empresas integrantes de la muestra, recogida básicamente en el balance de situación, la cuenta de pérdidas y ganacias y el cuadro de finaciación referidos al bienio 2001-02. En esencia, el Barómetro Industrial LEON 50 pretende ser un avance en el análisis, diagnóstico y mejor conocimiento de la industria regional, aportando una visión actualizada sobre estrategias y pautas de actuación empresarial que serán objeto de observación en períodos
De eerste etnografische monografie: De Kaffers aan de Zuidkust van Afrika (1810) van Lodewyk Alberti
Siegfried Huigen
Tydskrif vir letterkunde , 2006,
Abstract: This paper examines the ethnographic discourse in the first ethnographic monograph which appeared in the Netherlands, De Kaffers aan de Zuidkust van Afrika, Natuur- en Geschiedkundig beschreven (1810) by Lodewyk Alberti. Within a European context this book is unique for being the only successful implementation of the ethnographic questionnaire of Joseph-Marie Degérando, the Considérations sur les diverses méthodes a suivre dans l'observation des peuples sauvages (1800), and the anthropological ideas of the Société des Observateurs de l'homme. In Alberti's case, this resulted principally into a focus on the cultural aspects of ethnographical description. Furthermore, Alberti was the first to proof the usefulness of ethnographic knowledge in the management of colonial relationships. The personal aim of his book was to apply for the position of landdrost of Uitenhage, assuming that the Cape Colony could be restored to Dutch rule, which was in 1810 still a possibility.
