Projects

Pedro Nunes Complete Works (Obras de Pedro Nunes)

The publication of Pedro Nunes' Complete Works has been my most absorbing task in the past years. The Project was publicly announced in December 2002 in a solemn session at the Lisbon Academy of Sciences. The President of Portugal (at the time Dr. Jorge Sampaio) was there and gave a speech.

Up to now four volumes (of a total of eight) were published:
    Vol. I: Tratado da Sphera & Astronomici introductorii de spaera epitome (2002)
    Vol. II. De crepusculis (2003)
    Vol. III. De erratis Orontii Finaei (2005)
    Vol. IV, De arte atque ratione nauigandi (2008)
    Vol. V. In theoricas plaetarum Purbachii annotationes (scheduled 2010)
    Vol. VI. Libro de algebra en arithmetica y Geometria (scheduled 2010)
    Vol. VII. Manuscripts (scheduled 2011)
    Vol. VIII. Documents and Biographical materials (scheduled 2012)

Recently, with the publication of vol. IV of this edition there was another surge of attention. Ana Machado wrote a nice piece in Público (6 August 2009, «Primeira edição da obra de Pedro Nunes está pronta e a dar muito que falar ... lá fora») and Luís Tirapicos, in Expresso (8 Ago 09, «Crítica de livros de 8 a 14 de Agosto») made a rather positive review on the book. João Filipe Queiró wrote a short notice, published in several places (e. g. here), and I was interviewed by the Jornal de Mathemática Elementar -- see here and here.


Manuel Dias' Tianwenlüe 天问略

I am working with Rui Magone (MPIWG, Berlin) on the edition of Manuel Dias' Tianwenlüe 天问略. It has been great fun, but also lots of work. You can check the blog where we discuss our progress in detail. [Well, you cannot yet. The blog is still restricted, but we will change that shortly...]

The Tianwenlüe 天问略 is famous because of this last page, where Galileo's telscopic observations are described for the first time in Chinese, but there are many more things of interest in the text.

If you're interested in looking at the text, the Tianwenlüe 天问略 is online at the Ricci Institute in San Francisco.
You can also see some papers we wrote already.

Newspaper Público (Ana Machado, 19 Jun 09), in a nice piece titled «Foi Manuel Dias que ensinou aos chineses quem era Galileu» covered our work. This gave some publicity to Tianwenluë and Manuel Dias.


Genna-kokaisho

I have been working with José Miguel Pinto dos Santos on the Genna-kokaisho (1618) [Voyage of the Genna-age] the Japanese translation and adptation of a Portugese nautical guide.It was written by one Ikeda Koun after travelling with pilot Manuel Gonçalves from Nagasaki to Luzon, in the Philipines.

Genna-kokaisho is online here.

This is the second time I am involved in a project with José Miguel. Years ago we studied the very important text Kenkon bensetsu.
We published a paper together and then he went on to study the text in more detail and publish more.


Scientific Manuscripts of the Biblioteca Nacional de Portugal

Although formally ended as a FCT Project, («Património científico e cultura manuscrita: A colecção de manuscritos científicos da Biblioteca Nacional, Lisboa», POCTI/HCT/58543/2004) the Cataloguing of the scientific manuscripts at the Biblioteca Nacional de Portugal continues. Some 1000 manuscripts were analysed and catalogued so far -- and some nice findings I will be reporting here...


Database of bibliography on the HIstory of Science in Portugal

Still working with Conceição Tavares on the Bibliografia de História da Ciência em Portugal, for the years 2005-2008. It's more than a book. We plan to set up a database with all bibliographical references.


Books and Science

I have long been interested in Libraries and Books on scientific matters. I already collaborated with renown international book dealers (e. g. Martayan Lan, in New York) and many rare book dealers in Portugal.
Here's a good bibliography on scientific books:
