This project is situated within the context of an innovation of the biology curriculum in Dutch secondary schools. The main purposes are (1) to clarify the relation between teachers’ practical knowledge and the decisions they make when planning and implementing their lessons and (2) to develop a professional…

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

Connecting Agriculture, Crafts, Construction, Transport, and Resilience Strategies

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

To what extent and how do identity processes influence health behavior?

Professor Renata Kallosh (Stanford University), one of the world’s leading theoretical physicists, will be this summer’s Lorentz Professor at the Leiden institute for theoretical physics. Her main areas of interest are cosmology and string theory. She studied physics in Moscow, where she also obtained…

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Combining geometry and number theory. That is what Dr Jan Vonk of the Institute of Mathematics receives a Vidi grant for today. ‘By fusing these two disciplines we may be able to solve a century-old mathematical problem.’

Leiden PhD student Peter Koymans has been declared ‘best mathematics PhD student’ by the Royal Dutch Mathematical Society (KWG). He received the prize at the Dutch Mathematical Congress (NMC) on 24 and 25 April. With his talk about his research into the Cohen-Lenstra conjecture, Koymans left eleven…

In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

In this thesis, we address two problems concerning the tautological rings of the moduli space of curves.

This subproject of 'From Homo Economicus to Political Animal' analyzes Greek economic thinking of the Hellenistic period.

What makes a truth true? Throughout the history of philosophy, numerous theories have been proposed to define what it means for something to be ‘true’. Despite their wide variety, most accounts presuppose that a truth is expressed through linguistic assertations or propositional statements. But can…

This subproject of 'From Homo Economicus to Political Animal' will be on ancient analogues for modern-day “ersatz economics”, the economics of the “man in the street”.

How public service motivation and professionalism affect decision-making in dilemma situations. Individuals who work in the public sector see themselves confronted with conflicting values, contradictory demands, and the need to serve an at times difficult to define ‘public interest’.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Lecture

How does contemporary art and culture represent nuclear contamination in post-nuclear landscapes?

This thesis analyses the existence and the functioning of the urban labour market in the early Roman empire by looking at the crucial influence of social structures, such as the family and non-familial labour collectives.
