The photograph taken at Glastonbury (Mud at Glastonbury festival – in pictures, theguardian.com) suggests that physics should be a core subject in schools. That way people might learn a) not to take a small-wheeled buggy to a muddy field, and b) if they do, to pull it and not push. Or maybe we should teach logic?

• Not only did the Romans not stop at Exeter, as Steven Morris suggests (Wine and olives: what the Romans did for Devon, 23 June), they ventured beyond the Tamar into Cornwall, as revealed by the 2011 discovery of a Roman fort on the Cornish bank of the river at Calstock.

• When Women to Women for Peace held their 30th anniversary in 2011 our Japanese delegate, Keiko Miyamoto, a volunteer at the Hiroshima Memorial Centre, spoke movingly about peace holding 1,000 cranes in her hands. Such a powerful symbol of peace (Paper cranes too scary for Trident police, 13 June).
