Science and Technology

This group is for the study and discussion of any new scientific or technology topics, innovations, discoveries or work in progress, and their potential consequences. Recent talks have included the Starlink internet constellation, the evolution of wi fi, DNA to RNA to protein, forever chemicals, sewers and sewage treatment, space probes, graphene at 20 and transmission electron microscopy. Topics are presented by group members, with the occasional outside speaker. Most meetings are held online, but four times a year the group meets in person at Trinity Henleaze United Reform Church; it does not normally meet in July and August.
