This book is intended to provide a self-contained introduction to the principles of Quantum Mechanics, based on the analysis of measurement processes of microscopic systems and the introduction of the physical observables as generators of symmetry transformations. After standard training arguments the applications are mainly focused on atomic and nuclear phenomena, as they occur on a quite different space-time scale. Thus, the text flows from the simplest systems, i.e. proton-electron in the hydrogen atom and proton-neutron in the Deuteron nucleus, to the complex many- body systems, i.e. stable states of atoms and nuclei of the periodic table, and finally to infinite many-body systems, including atomic and nuclear fluids. A digression is made on the application to astrophysical compact systems. The textbook is suitable for upper undergraduate students and graduate students in physics and related majors.

The NRP70 project "The Future of Swiss Hydropower: An Integrated Economic Assessment of Chances, Threats and Solutions" (HP Future) has been initiated in 2014 with the objective to identify options for Swiss hydropower (HP) to adopt to the ongoing and expected electricity system changes. The project has been finalized in 2018 and this final report provides an overview of the obtained results and insights. Following a short summary of the main findings is provided.

Swiss Hydropower (HP) is currently facing a wide range of challenges that have initiated a debate about future prospects and its role within the envisioned energy transition. Building on this debate, this paper provides an overview of the status and prospects of Swiss HP by identifying and evaluating the different drivers and uncertainties that Swiss HP faces. Based on a review and the perceptions held by some of the main Swiss HP stakeholders the two main topics that need to be addressed are the market driven impacts and the political, legal and social aspects. While the market dynamics cannot directly be influenced by Swiss companies or authorities, the regulatory framework can and needs to be adjusted. However, this requires a comprehensive stakeholder process and is at least a medium-term process.
