Ignas Snellen over complex buitenaards leven
Het aantal planeten waarop complex leven kan gedijen, is kleiner dan gedacht. Beloftevolle tweelingen van de aarde blijken bij nader inzien slechts beperkt levensvatbaar, stellen astronomen. Ignas Snellen van de Leidse Sterrewacht reageert in DeMorgen op het nieuws.

De complexiteit van Groningen en vertrouwen
Sinds de gasbevingen in Groningen worden ‘vertrouwen’ en ‘overheid’ daar niet zomaar meer met elkaar geassocieerd. Dat leverde de casus op van de Honours Class ‘Gaswinning in Groningen en het fenomeen van vertrouwen in de overheid’, waarin studenten erachter kwamen hoe complex een begrip als ‘vertrouwen’…
