Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Considering the ways in which the ‘global turn’ is changing the theory and practice of historical disciplines, Explorations in History and Globalization engages with the concept and methodology of globalization, challenging traditional divisions of space and time to offer a range of perspectives on…

Leiden Center for the Study of Ancient Arabia

Although nanoparticles are extensively used in various applications like consumer products and have most probably entered the environment, little is known about the effects of these particles on living organisms.

LeiCenSAA is dedicated to the study of Ancient Arabia and the sharing of knowledge and expertise on this topic. Thefore it aims to collaborate closely with other research in the field.

An overview of Professional Associations and Journals

If Dutch cinema is examined in academic studies, the focus is usually on pre-war films or on documentaries, but the post-war fiction film has been sporadically addressed.

This book provides an overview of critical scholarly reflections on the history of Dutch slavery and colonization, as well as how this translates into critical cultural practices.

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…

An international team of astronomers from Leiden Observatory and others, has for the first time mapped a piece of the dark, cosmic web. The research strengthens the hypothesis that the young universe consisted of huge numbers of small groups of newly formed stars. The astronomers publish their findings…

From fake news via WhatsApp to mini hearts from a 3D printer: four Leiden researchers have been awarded a Consolidator Grant by the European Research Council. These grants, of up to 2m euros, enable researchers to establish or expand their research team and continue to develop their career.

As Director-General of the ESO for the past ten years, Leiden University astronomer Tim de Zeeuw had ‘the best astronomy job in the world’. Back at the Leiden Observatory, he is focusing on the first 3D map of the Milky Way.

How do stars and galaxies form? What is dark matter? To answer these and other questions, we need increasingly large telescopes. And to build these, we need international partnerships. A series on the impact of collaboration.

Five projects with researchers from Leiden University have received a grant from the Dutch Research Council (NWO) to build or upgrade existing research facilities.

No less than four Leiden research teams have been awarded a grant by NWO. On 27 July NWO honoured 21 applications in the Open Competition ENW-XL. NWO awards the grants to consortia in the exact and natural sciences who are doing unconnected fundamental research that is 'driven by curiosity'.

In personal stories, university staff and students with different backgrounds reflect on our colonial and slavery past. How does this history affect the present and the future?

Mining the unusually rich diaries, memoirs, and poems written by Netherlandish Catholics, Judith Pollmann explores how Catholic believers experienced religious and political turmoil in the generations between Erasmus and Rubens.

The Khoesan were the first people in Africa to undergo the full rigours of European colonisation. By the early nineteenth century, they had largely been brought under colonial rule, dispossessed of their land and stock, and forced to work as labourers for farmers of European descent.

For hundreds of years, the island of Sri Lanka was a crucial stopover for people and goods in the Indian Ocean. For the Dutch East India Company, it was also a crossroads in the Indian Ocean slave trade. Slavery was present in multiple forms in Sri Lanka—then Ceylon—when the British conquered the island…

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…
