## Poe on algebraists

Michael Kinyon reminded me of Edgar Allan Poe’s comments on algebraists in his story “The Purloined Letter”. Here they are in full. “But is this really a poet?” I asked. “There are two brothers, I know; and both have attained … Continue reading

## An organ recital

Last week, the refurbished organ in the Great Hall of the People’s Palace at Queen Mary was officially inaugurated. Along with the Purcell, Bach, Handel, Wesley, Ketelby, Coates, and so on, was a piece by my colleague and co-author Donald … Continue reading
