Mechanics Meets Energy 2020

The eights edition of the Mechanics Meets Energy symposium took place at the Ludwig Windthorst Haus (LWH)/Lingen. From January 13th – 17th 2020, i.e. just short of the shutdown caused by the COVID-19 pandemic, we spent another busy week with 56 presentations, again including three by internationally renowned guests. The occasion also marked the farewell of our group leaders Christoph, Steffen, and Matteo and the welcome of Jazmin and James. In addition, we made a trip to the famous Mayer wharf in Papenburg, marvelling the macro-mechanics of cruise shipbuilding. Thanks once more to the organising skills of Carola & Steffen and the superb facilities at the LWH, we spent another enjoying and enlightening symposium.
