The hashtag #Pferdlosgeritten in my profile description is borrowed from a 1939 book (/The Classical Groups/) by mathematician #HermannWeyl (1885-1955) , who had taken it from #GottfriedKeller. It summarizes my frequent feelings at having to live a great part of my life in English, although my mother tongue is French
