SciLogs (acronym for science and blogs) is a transnational project for scientific debate and reflection.

Since 2008, experts from various fields of knowledge share in SciLogs ideas, reflections, comments and opinions on topics related to science. These logbooks, grouped into seven thematic areas, are conceived as a space for exchange and dialogue, which allows to address science in all its complexity: foundations, history, research, findings, applications, values, philosophy, politics, teaching …

SciLogs is an independent source of information. The authors write with complete freedom and without any editorial commitment to the journal.

SciLogs is an open community. If you are a researcher and want to share your interest in science through our family of blogs
