What is the origin of educational ideas, e.g., the idea that intervention in infancy has long-lasting effects on development.

The research programme Probability Theory focuses on probability theory and on operations research.

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Does the nature and extent of political communication networks, measured through the frequency and multiplexity of information exchange ties, play a critical role in the reconstitution and maintenance of the Chinese Empire?

Osteoarchaeology is a rich field for reconstructing past lives in that it can provide details on sex, age-at-death, stature, and pathology in conjunction with the cultural, social, and economic aspects of the person’s environment and burial conditions. While osteoarchaeological research is common in…

How did institutions and structures operate throughout the Muslim world from the earliest history of Islam into the early modern period?

The research of the Algebra, Geometry and Number Theory cluster tries to bridge the gap between abstract theory and the world of algorithms and applications.

The Death of Archaeological Theory, edited by John Bintliff and Mark Pearce, addresses the provocative subject of whether it is time to discount the burden of somewhat dogmatic theory and ideology that has built up over the last 25 years.

The current study focuses on Walpole’s social network and the language as contained in the letters of the network members.

What are the differences between the trade in Chinese herbal drugs in Europe between 1800 and now? Can we see the major metabolic changes after 200 yours?

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

The master’s specialisation Algebra, Geometry and Number Theory at Leiden University is aimed at students who wish to acquire a profound knowledge of one of the areas within pure mathematics. There is a strong theme dealing with algebra and number theory as well as a strong theme dealing with topology…

Sentencing is becoming increasingly complex for the courts. Legal scholars and criminologists from Leiden document the process of sentencing in the Netherlands. They use this knowledge to advise legislators and those who implement this legislation on how to make sentencing more consistent and effect…

Edited by linguists Jenny Audring (Leiden University) and Francesca Masini (University of Bologna), this is a unique handbook with a focus on morphology theories rather than morphological data. It covers a wide array of morphological theories, from traditional twentieth century models to current theoretical…

The master in Cultural Analysis: Literature and Theory at Leiden University focuses on the study of literature from a comparative and theoretical perspective, with a special emphasis on literary movements and genres of the 19th, 20th, and 21st centuries. It covers a wide range of languages and cultures…

The specialisation Global Order in Historical Perspective of the master’s in International Relations at Leiden University focuses on examining the historical processes behind the evolution of the global order.

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

On December 5th, Matthias Pache succesfully defended his doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Matthias on this great result.

Through extensive archaeological and documentary research, this study aims to provide a detailed analysis of the maritime cultural landscape of St. Eustatius over the past four centuries. It focuses on bridging the gap between the marine and terrestrial worlds and demonstrates that in order to truly…

Historical geo data are gaining in importance. Provided that they are exactly geo referenced, they can be stored into a GIS and thus be combined with all kinds of maps (topographical, pedological, etc.) and datasets. This makes it possible to analyze historical developments in space and time on a detailed…

Johannes Boer's research intends to question the way explicit knowledge is applied in order to restore and perform music from the past with the intention to get as close as possible to its original meaning.

The terms ‘social’ , ‘collective’ or ‘public’ memory, are often contrasted with ‘private’, ‘individual’ or ‘personal’ memory. All these terms derive from a fairly new and interdisciplinary scholarly field that is often referred to as ‘memory studies’, and that according to some critics has developed…

This study looks at the question of how and at what level students in primary teacher education can integrate theory and practice, and how the organisation of their learning environment, focusing especially on mathematics and pedagogy, can contribute to that.

In this paper for Defence Strategic Communications, Alastair Reed and Jennifer Dowling seek to show the importance of historical narratives to propaganda by identifying and exploring five ways in which such narratives are exploited to reinforce the extremists' 'competitive system of meaning'.
