We hear too often about sudden death in adults following prolonged and often unnecessary police restraint. What do people know about the dangers of restraint and how widespread is our understanding of such deaths?
Clinical practice depends on the acquisition and analysis of evidence - detailed information from each patient’s clinical history, laboratory tests, imaging scans and biopsies. Yet data on its own is not enough, and must always be interpreted in the context of each unique person.
Mata Hari was an erotic dancer who, in 1917, was executed by the French army for treason. She has been portrayed as the ultimate femme fatale, extracting information from hapless men through exploiting her sensual charms.
Niklaus Wirth said Algorithms + Data Structures = Programs. But programs are more than that. They are ubiquitous in modern life, but only a tiny minority of the population know how to program.

Amelia Dyer was one of the most prolific murderers in Victorian Britain. She made a living as a “baby farmer”, or someone paid to care for unwanted or abandoned infants – except she killed around 400 of them. How could a mother and nurse murder so many defenceless babies?
This lecture will look at change ringing, which is ringing a series of tuned bells (as you might find in the bell tower of a church) in a particular sequence, and this has exciting mathematical properties. We will also ask: why are bells bell-shaped?
