The Old Observatory in Leiden has reclaimed its most important telescope. Since the 1960s, the Meridian Circle (also known as a transit telescope) had been housed in the Boerhaave Museum. After more than sixty years, the telescope is finally back in its original location. Now, the public can enjoy it…

Mathematician Oliver Nagy still vividly remembers the first time he learned about a random walk. ‘The lecturer told us to imagine a company of drunken students who wander in the streets. At each intersection, they would spin one of them around and all would go in the direction where he or she came to…

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

In the future, physicians may be able to identify dementia much earlier than they can today because a computer algorithm will be able to predict from brain scans how our memory is going to develop.

Collecting as much information as possible about administering a new medicine to people can save a lot of money.

They were called 'annoying brats', the group of campaigning scientists who in 1978 founded what is now an internationally acclaimed ecological research institute. Their stories and those of the current staff of the Institute of Environmental Sciences are described in the book 'Forty years of Leiden…

What workflow of non-destructive techniques provides accurate, valuable data to improve our understanding of Caribbean archaeological landscapes? How were Amerindian settlements configured?

Even a small quantum computer should be able to simulate exactly the properties and behaviour of new molecules. This would take chemistry to an entirely new level. Better solar panels, more powerful batteries, saving lots of energy in the chemical industry: the applications have the potential to transform…

Scientists of Leiden University and Technical University Delft are going to predict how and where defects in sewer systems arise. They are working with light sensitive camera’s, based on new automated multi-sensor inspection with stereo vision and laser range scanning. Their models are going to process…

Machine learning - on classical computers- has made great progress in the past five years. Computer translation of speech and text is just one example. In Leiden, some researchers expect that machine learning, empowered by quantum systems, even if they only contain a few dozen qubits, can lead to a…

In this publication the results of the analyses of the Roman harbour of Voorburg-Arentsburg (NL) are presented. This fully inclusive and integrated study of more than 1000 pages is published in two volumes. The publication is written in Dutch, but has got an extensive synthesis/summary in English.

The debate about state behaviour in cyberspace may be set in the wrong legal key.

The main purpose of this book is to give a description of the Cholón language as represented in the Arte de la lengua cholona (ALC), a colonial grammar written in 1748 by a Franciscan friar, named Pedro de la Mata. The ALC was transcribed by Fray Gerónimo Clota in 1772. This grammar is kept in the British…

Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

Turnov, a town in Northern Bohemia, counting almost 15.000 inhabitants, is situated about 90 kilometers North-East of Prague, in the Semily district. It is the capital of the Bohemian Paradise.

Bone research provides plenty of detailed data about the health of a person or a group. This data is not only used to reconstruct the past but also to fight disease today.

A critical look at the impact assessment modelling of metals in Life Cycle Impact Assessment and improvement options.

Ancient Greek was spoken in a large number of different dialects. Although we do not find direct evidence for syllabic liquids in any of our sources, comparative evidence shows that these sounds must have been present in Proto-Greek, and that they were retained until comparatively recently in the prehistory…

Han De Jong gave an overview of (the run-up to) the current economic crisis and discussed which steps could be taken to resolve this crisis.

What is the difference between highly visible and poorly visible monuments on the alignment? And is this difference reflected in the social position of the dead buried underneath these mounds.

The Algebra, Geometry and Number Theory specialisation gives you profound knowledge of pure mathematics. The focus is on both fundamental mathematics and on applications in other sciences, society and industry. During your master’s you will be part of one of the multidisciplinary research teams at the…

The Mathematics and Education master specialisation gives you the opportunity to combine Mathematics research with an excellent education in becoming a Mathematics teacher.

Arranging accommodation can demand a lot of time and effort for Dutch and international students. For this reason, finding a place to stay is one of the first things that need to be arranged when you are planning to study at Leiden University. But how do you actually find a room in Leiden?

Combine training in Mathematics research with different aspects of business studies. Learn to build bridges between science and business.

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

Prof. dr. Frank den Hollander has been named Fellow of the Institute of Mathematical Statistics (IMS). Professor den Hollander received the award for his research in probability and mathematical physics, and especially large deviation theory.

The DASPO-group for data analysis and survival in personalized sarcoma at the Mathematical Institute has developed an app that provides personalised predictions for patients suffering from soft tissue sarcomas. Due to the aggressive nature of such tumors, the prognosis for such patients is poor, even…

Nanodiamonds and charcoal in Dutch soil provide no evidence for the alleged impact of a meteorite at the end of the last Ice Age. This is the conclusion of a research done by Utrecht University in collaboration with Leiden University and the University of Groningen.

A full overview of all loans and debts between banks would help preventing a new financial collapse. But banks do not provide this information. An econophysics model by Diego Garlaschelli and collaborators reconstructs the most probable situation and finishes first place in two independent tests.
