The Netherlands is not particularly rich in ‘wild nature’. Comparatively, what we have is a lot of intensively used agricultural land. This means that from nature’s perspective there much to be gained by combining the ‘nature’ and ‘agriculture’ functions. Not an easy task in such a densely populated…

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

Colonial and Global History combines a deep curiosity of transcultural processes such as imperialism, (de)colonization, and globalization with critical historical research on regional societies in Africa, Asia, and the Americas.

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…

The excuses for the slavery past? It would have been better if the cabinet had taken some more time on that, thinks university lecturer and Atlantic slavery expert Karwan Fatah-Black. 'Too bad they didn’t wait for the results of the study.'

Scientists regularly appear in the media. They participate in science cafés, write a popular-science book or visit school classes. In that way, they want to convey their knowledge and enthusiasm to society. But do they succeed? To answer that question, a new website is launched, with a toolbox full…

A European project should help reinvigorate Latin teaching in secondary schools. 'By focusing on citizenship, we want to show that Latin is relevant to discussions about citizenship and migration.'
