Botanisch filosoof Norbert Peeters vertelt over hoe mensen omgaan met planten in het algemeen, en met onkruid in het bijzonder.

Onlangs verscheen het boek ‘Afgrond zonder vangnet’ van Yra van Dijk, hoogleraar Moderne Nederlandse Literatuur. In haar boek analyseert ze verschillende thema's in het werk van Arnon Grunberg.

Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

Collaboration is increasingly common among teachers in schools. As such, teacher education should prepare prospective teachers to effectively interact with other teachers in different types of communities or groups.

Below are some of the scholarly works published within the context of the Institutions for Conflict Resolution programme.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

Terrorist groups adapt to environmental changes to maintain power. This project provides new insights by developing a theory of strategic target selection and using big data analytics and machine learning to test these hypotheses.

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Our research primarily focuses on the early universe and its origins in theories that go beyond the Standard Model of particle physics.

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

On Tuesday 7 September 2021, the new Faculty year was opened with the Leiden Law Op 1 Talkshow. Various guests shared their thoughts and expectations for the new academic year. Lotte Kremers and Bastiaan Rijpkema presented the show.

To be eligible for Public International Law at Leiden University, you must meet the following admission requirements.

The research group on Diplomacy and Global Affairs studies international diplomacy, international organisation, global, transnational, multi-level and comparative governance.

People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

We are interested in understanding the mechanics of soft materials, of which biological materials are prominent examples.

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Health inequities, obesity among children, loneliness, performance stress among youngsters. What are the drivers behind such ‘wicked problems’ and how might they be related? This interdisciplinary minor offers you the possibility to work with societal partners to gain a deeper understanding of real-life…

De rechtbank van Rotterdam geeft zorghulp Carol Kollmann gelijk in haar rechtszaak tegen het UWV. De zorghulpverlener vond dat ze recht heeft op een WW-uitkering en het meetellen van haar arbeidsverleden voor de WW, nadat ze erachter kwam dat ze daar door de zogeheten Regeling dienstverlening aan huis…

The Leiden Political Economy Group (L-PEG) is a multi-disciplinary network of scholars with a research interest in (comparative / global) political economy based at Leiden University. Our members belong to various institutes and faculties across Leiden University, and from other universities across…

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…

Enforcement of group cooperation fails because of discriminatory punishment, according to research by Welmer Molenmaker and colleagues. When group members have different backgrounds, punishment turns into a double-edged sword: no longer used just to prevent group exploitation, but also to break the…

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

The programme group Research Methods and Statistics offers support to researchers from a variety of research projects within Education and Child Studies.

The development of space resource activities is happening now. In the absence of a clear framework to govern these activities, there is a need to examine the concepts that are being discussed in order to ensure that they meet existing treaty obligations regarding on-orbit operations and space resource…

Should we ban snack bars from neighbourhoods where residents are overweight or have diabetes? At the Common Sense about Health knowledge festival, scientists, civil servants and other professionals discussed how South Holland can become healthier. The Healthy Society Map makes it clear where there are…
