A good curve

is a delight. 
Today started with a good jog along the Tyne, followed by peppery black pudding, inter alia. Then a treasure hunt for the right room in the Uni of Northumbria, where our meeting with teachers of AQA Computer Science was competing with the rather larger Big Bang. 

By the time we'd done that the drizzle set in, but the Metro is dry, and so is the splendid Central Station. On, to London.
