In a world characterised by growing international conflicts and existential threats to humanity, international law is becoming increasingly important. The book "Teaching International Law" sheds light on this urgency and offers profound insights into the challenges and opportunities of teaching international law.

The Secret Diary of Karl Benedikt Hase

Karl Benedikt Hase (1780–1864) is recognised as one of the foremost Greek scholars in the French academia of his time. The LAGOOS project has at its core the discovery of 9 volumes of the private diary of Hase, written in Ancient Greek and preserved at the Goethe- und Schiller-Archiv, Weimar. Specialists of Late Antique and Byzantine history and literature applaud the outstanding value of his work as an editor and commentator. They have also, however, identified him as the perpetrator of a series of forgeries on documents of Byzantine history.

The results provide new insights into dark energy, the nature of the Universe and confirm a rejected hypothesis of Albert Einstein.

The “su­per­ra­di­ance” revis­ited

Theoretical physicist Farokh Mivehvar has investigated the interaction of two collections of atoms emitting light inside a quantum cavity – an optical device consisting of two high quality, tiny mirrors facing each other that confines the light within a small area for an extended time. The model and predictions can be implemented and observed in state-of-the-art cavity/waveguide-quantum-electrodynamics experiments and might have applications in the new generation of so-called “superradiant lasers”.

Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental assumption for air quality forecasting has to be reinterpreted for urban areas. Measurements by an international team led by atmospheric scientist Thomas Karl of the University of Innsbruck also show that direct nitrogen dioxide emissions are overestimated.

Tur­bu­lence: Decades-old the­ory gets a major remake

Turbulence plays an essential role in weather and climate, and correctly representing its effects in numerical models is crucial for accurate weather forecasts and climate projections. However, the theory describing the effect of turbulence has not changed since its conception in 1950s, despite the fact that it is not representative for the majority of the Earth’s land surface, especially over mountains and polar regions. The Innsbruck meteorologist Ivana Stiperski has now extended the turbulence theory to complex atmospheric conditions. The researcher thus paves the way for the first generalized turbulence theory over complex terrain.
