You find here texts written over the years for a broad public. You also find descriptions of our sailing on board Cérès, our sailing boat between 2005 and 2018. The texts relative to our crossing of Russia on the inner waterways and the White Sea might be of particular interest.

Since 2019 we conduct the project Science et voile avec Gaia which links sailing stories with texts describing the elements we come across, be they geological, atmospheric or related to fauna, flora and human populations. The website of this project is https://sy-gaia.ch/.

On the following pages you find texts that I wrote since 2012. These reflexions have often been in response to sollicitations I received either as president of the Swiss Academy of Natural Sciences (that I presided between 2012 and 2015) or as president of the Swiss Academies of Arts and Sciences (that I presided between 2013 and 2015) or as president of the European Astronomical Society(that I presided between 2010 and 2017).
