Mientras hay vida hay esperanza

Este clip va dedicado a la esperanza. Por supuesto no se trata de interferir en la política de la comunidad de Madrid, ni de hacer una reflexión sobre virtudes cristianas, ni de reconocer en público que esta palabra forma parte de nuestros sentimientos más nobles cuando estamos dando clase. Lo que nos proponemos es hacer referencia a tres casos muy concretos de esperanza matemática.

Making hay while the sun shines? Socio-economic change, cereal production and climatic deterioration in Early Medieval Ireland

The Early Medieval period in Ireland (c. A.D. 400–1150) has been the subject of much archaeological and historical study. The recent application of various forms of archaeological sciences, as well as palaeoenvironmental studies, to the archaeological record have, however, added fresh impetus to this study area. It seems increasingly evident that significant changes to economy and society occurred during this period and were not recorded in detail in the contemporary documentary sources. This paper will attempt to outline those changes and to assess whether, or to what extent, they were influenced by climate change.
