The Garden Classroom, which is organising this event, won the Lisa Pontecorvo Award in 2015 (for its outstanding work and contribution to people and spaces).
Anna McKane arranged for a group of enthusiastic runners from goodgym to spread mulch around the roses in Thornhill Square Gardens. They appeared to have enjoyed both the running and the thought of helping the community, and we should be able to enjoy the outcome. There are more pictures, and more details of what they did, here.
‘Superposition’ combines physics, art and history: the Institute of Physics asked an artist to design a work for the eastern ice well of the Canal Museum. The result refers to particle detectors, especially to neutrino detectors (which are in deep mines). On Thursdays, Saturdays, and Sundays until 20 October visitors can climb down into the ice well to see it for themselves; there are also pictures relayed from the ice well to the normal visiting area and to the web site. On 17 October the artist (Lyndall Phelps) and a physicist (Ben Still) will talk about the work (which they call ‘Covariance’). There are many more details here.
