We study the physics of a broad range of biological and soft materials

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Not all problems are easy to solve, but with enough bright minds, you make progress step by step. ‘The kind of problems I am interested in have been occupying mathematicians for over two millennia,’ says theoretical mathematician David Lilienfeldt. In September, he started at the Mathematical Institute…

Does gravity work the same when you look at the largest scales in our universe? That’s what Leiden physicist Alessandra Silvestri will study with a 2 million euro ERC Consolidator grant. ‘We assume that it does, but we don’t actually know.’

With an MSc degree in Mathematics you are well prepared for a broad range of career prospects and ready to operate on the international market. The master’s degree is also an excellent preparation for pursuing a PhD degree.

Theoretical physicist Stephen Hawking (76) passed away on 14 March at his home in Cambridge, having been a long-term sufferer of the muscular disease ALS. A number of Leiden scientists look back at the life and scientific career of this world-famous physicist. 'He was very approachable and extremely…

Alumnus Allard Altena (27) is mentor of the month. He worked at the Public Prosecution Service and is now a regulator at the Dutch Authority for the Financial Markets (AFM). He wants to share his broad experience with students and young alumni – you too perhaps?

Self-employed workers’ hours have significantly decreased during the coronavirus crisis. Their average hours worked decreased most at the start of the crisis, by more than five hours per week. And it was difficult to return to their pre-crisis hours in the quarters that followed. This is the conclusion…

There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…

In the Dutch healthcare system, only MHC psychologists (GZ-psychologen) are licensed to practice psychology unsupervised.

The MSc programme Physics offers 5 research-oriented specialisations where you can focus on Theoretical Physics, Quantum Matter and Optics, Biological and Soft Matter, or Cosmology. You can also combine Physics with education, management or science communication.

The master's specialisation Astronomy and Cosmology at Leiden University covers all aspects of modern astrophysics, including observation, interpretation, simulation and theory. This programme is essentially based on combined research in astronomy and physics and is therefore open for students with…

The EU is struggling with labour shortages. Migrant workers and asylum seekers would be able to fill this gap and solve many of these problems. But, says economics professor Olaf van Vliet, the pros and cons regarding this dilemma need to be explicitly addressed. 'Now the message in campaigns focusses…
