When did the Mali Empire disintegrate? What does the Sunjata heritage demonstrate about the political situation after 1600?

What did plays look like in the seventeenth, eighteenth or nineteenth centuries? With the new OverActing theatre festival, university lecturer Jed Wentz is trying to get closer to an answer to that question.

LCD screens use liquid crystals which have a high degree of order, even though they form a fluid. A new theory maps out the interplay between order, temperature and symmetry. Publication in Physical Review X.

Adopting a largely chronological approach, Gerrits links the historiography of post-war Europe and the major theoretical approaches to nationalism with analysis of key historical developments and events.

This dissertation shows that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

This dissertation provides crucial but as yet missing empirical data on the tone accent opposition in the so-called

This volume brings together experts on the history of the various revolutionary Sister Republics.

What can Robotics and AI bring to archaeological theory and practice? In return, how can archaeology contribute to the developments in robotics and AI research? Colleagues tackled these questions at an event organised by the Faculty of Archaeology and sponsored by SAILS.

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

There are a number of problems in philosophy that seem to share a similar possible solution: 'Why do promises and contracts bind?', 'Why ought citizens and judges obey the law?' and 'Can we realize the gains to be made from cooperation?'. All three problems (as well as some others) share a possible…

‘What I find most alluring about soil life is that you can steer it,’ researcher Martijn Bezemer of the Institute Biology Leiden (IBL) reveals. ‘You can ask: What do you want? And then I can transform the soil into something you need. At least, that is what we thought.’

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

This is the first comprehensive commentary on a section of Xenophon's Anabasis in English for almost a century.

What makes a good historian? When historians raise this question, as they have done for centuries, they often do so to highlight that certain personal attitudes or dispositions are indispensable or studying the past. Yet their vieuws on what virtues, skills or competencies historians need most differ…

This comparative study investigates court politics in four kingdoms that succeeded the south Indian Vijayanagara empire during the sixteenth to eighteenth centuries: Ikkeri, Tanjavur, Madurai, and Ramnad. Building on a unique combination of unexplored Indian texts and Dutch archival records, this research…

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Using mathematics to determine whether scientific results are significant or not. Peter Grünwald, full professor of Statistical Learning at the Mathematical Institute (MI) and senior researcher in the Machine Learning group of Centrum Wiskunde & Informatica (CWI), has been awarded an ERC Advanced Grant…

Every summer, Leiden University is the setting of dozens of summer schools in which professionals and students can receive extra training on a specific topic within a short space of time. We took a look at a summer programme on extremism. ‘A recruiter for al-Qaeda said that I could change the world.…

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…
