This doctoral thesis comprises four studies on the content and structure of physics teachers’ belief systems about teaching and learning physics in secondary education in the Netherlands.

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…

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

The master’s programme Physics at Leiden University offers a wide range of specialisations from theoretical research to cosmology. You will be trained for a career in research or for a more practical-oriented specialisation. The programme offers a wide choice of individual study paths that take into…

Studying Physics is an exciting journey through the foundations of nature: from the infinitesimal (particle physics) to the grandest scale (cosmology). Physics is a varied study programme that provides a solid foundation in theory and experimentation, with attention devoted to their practical applic…

Leiden has a strong tradition in theoretical physics, thoroughly linked with experimental disciplines.

How can we stay fit during hybrid working?

The Physics and Biological and Soft Matter master's specialisation is one of the two programmes that Leiden University offers in experimental physics. This programme mainly focuses on Biological Physics and Soft Matters Physics.

The master’s specialisation Physics and Education at Leiden University prepares you to teach the subject of physics to secondary school students. The programme comprises a one-year physics component, followed by an education component in the second year.

The Physics master’s programme offers you a research intensive and tailor-made study path on current topics in experimental and theoretical physics at an institute of international renown. We offer five research specialisations, with emphasis on either experimental or theoretical physics, which train…

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.…

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

The master’s specialisation Research in Theoretical Physics prepares you for a PhD position in theoretical physics. The research entails a broad range of topics including High Energy Physics and Particle Cosmology, Theoretical Physics of Life Processes and Condensed Matter Theory.

The master’s specialisation Physics and Science Based Business at Leiden University bridges science and business development by focusing on areas such as technology management, innovation, entrepeneurship, operations, and decision making.

Persistent somatic symptoms are long term symptoms that lack a clear medical explanation. These symptoms have a high prevalence where most people know someone who experiences such symptoms or they experience such symptoms themselves. Symptoms can vary greatly in and between people. While one person…
