Should the law and norms applicable to armed conflict include a distinct category covering the transition from armed conflict to peace, jus post bellum, and if so what are its characteristics?

Mexico, between 500 B.C. and A.D. 900

Do humans have free will? Does the world look different than it really is? Can moral judgements be right or wrong? In the Dutch-taught Bachelor's programme Philosophy at Leiden University you will ask questions that cross different disciplines and you will study the theories of classical thinkers,…

Blood, Sweat and Tears: The Changing Concepts of Physiology from Antiquity into Early Modern Europe

Why does the textural gap between the music that one can improvise and that which one can practice and learn to play (as in completely written-out music) seem to be bigger in the case of the guitar than, for example, in that of keyboard instruments?

The master’s programme in Egyptology, a specialisation of the Classics and Ancient Civilizations programme, at Leiden University provides you with a multidisciplinary study of the languages, literatures and cultures of Ancient Egypt.

In the master’s programme in Archaeology, you can follow courses on the archaeology of the Mediterranean, deepening your understanding of this fascinating region. From the many faces of ‘Hellenism’ to the early rise of the Roman Republic, to the voyages of European Crusaders in medieval times. The archaeology…

On June 22, the week of data literacy started. The week was organized by PublicNL in close collaboration with LCDS. The essence was: How do we deal with data in the future? What major changes did we see in the past five years and what expectations may we expect for the future? Are there any pointers…

Making the most vibration-free, cryogenic scanning tunneling microscope in the world. A bold mission, but one that PhD candidate Irene Battisti successfully executed together with the Fine Mechanical Department. The new microscope might shed light on how unconventional superconductivity works. PhD Defence…

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.
