From the beginning of Galileo’s career, well before the publication of the Sidereus Nuncius, his contemporaries took pains to shape his reputation and fame. They were fully aware that their efforts would shape the course of his career; they also knew that they would profit from helping him.

From 1550 onwards, a great interest in the natural world developed across Europe. This interest was not only stimulated by a growing knowledge of local flora and fauna, but also by the import of numerous exotic animal and plant species. Think, for instance, of researches and collectors like Gessner…

Bringing science, technology and innovation to places that normally do not have access to these areas of knowledge. This is the goal of the first Open Science Hub in Portugal, founded in 2017 in collaboration with Leiden University. The hub is managed by assistant professor of astronomy and society…

Students, first-time buyers, parents with stay-at-home children, migrants in need of a house; the problems in the housing market affect many layers within the society.

Just start somewhere: whether it's videos, board games, theatre performances, or festivals. That was one of the key insights Sophie Wintermans gained during the Science Communication Summer School. In her view, the Summer School is a great step for any scientist interested in science communication.

How does the government know whether science policy has the desired effect? According to Professor Barend van der Meulen, a variety of evidence about the effectiveness of science policy and proper gathering of this evidence are more important than a strict scientific method. Inaugural lecture 27 Ma…
