The Almagesti minor is one of the most important works of medieval astronomy. Probably written in northern France circa 1200, it is a Latin summary of the first six books of Ptolemy’s astronomical masterpiece, the Almagest. Also known to modern scholars as the “Almagestum parvum”, the Almagesti minor provides a clear example of how a medieval scholar understood Ptolemy’s authoritative writing on cosmology, spherical astronomy, solar theory, lunar theory, and eclipses. The author incorporated the findings of astronomers of the Islamic world, such as al-Battānī, into the framework of Ptolemaic astronomy, and he altered the format and style of Ptolemy’s astronomy in order to make it accord with his own ideals of a mathematical science, which were primarily derived from Euclid’s Elements. The Almagesti minor had a profound effect upon astronomical writing throughout the 13th-15th centuries, including the work of Georg Peurbach and Johannes Regiomontanus. In this first volume of the Ptolemaeus Arabus et Latinus text series, Henry Zepeda offers not only a critical edition of this little-studied text, but also a translation into English, analysis of both the text and its geometrical figures, and a thorough study of the work’s origins, sources, and long-lasting influence.

Als mijn printer letterlijk geld kan drukken, heeft dat dan grote gevolgen voor de wereld?

"Teaching Through Embodied Learning positions drama as an under-utilised but valuable tool for enhancing the learning of information in primary science texts. Creating a 'tableau' is an established drama practice for exploring key moments in fiction texts and historical events but less frequently applied with non-fiction texts. Based on doctoral research that studied the impact of having students create a tableau in response to reading informational texts about the solar system, it presents the idea that using drama with informational texts causes students to read purposefully and respond aesthetically; thus, positively impacting reading behaviour, comprehension and social behaviour"--

EXECUTIVE SUMMARY The general objective of the Report is to study the recent evolution of the social economy in the European Union. It focuses on three areas: firstly, the social economy and the emergent concepts/movements related to it, secondly, the public policies adopted in both the EU and the member states in recent years to enhance the social economy sector and thirdly, measuring the weight of the social economy in each EU member country. This Report shows that the European social economy provides over 13.6 million paid jobs in Europe, accounting for 6.3% of the total EU working population of the EU-28. Despite its size, the social economy remains invisible in the national accounts and statistics around Europe, a hurdle that constitutes another major challenge, although efforts have been made during the last two decades. The new concepts and approaches related to the social economy that have emerged in Europe, such as social enterprises, social innovation, collaborative economy, economy of the common good, circular economy and corporate social responsibility, have been analysed and the main public policies for the social economy that have been implemented in recent years have been studied. Special mention has been made of the Social Business Initiative (SBI) introduced by the European Commission.
