To celebrate Halloween. This lecture will look at tales of vampires and the undead with special reference to Central and Eastern Europe and some orthodox funeral customs used to placate and hopefully prevent their return as revenants to the world of the living. Participants are advised to bring garlic!

The study of dinosaur evolution is a growing field – thanks in part to an influx of new information from China, Argentina and other previously neglected parts of the world. New technology is also providing palaeontologists with new ways of extracting data from fossils discovered decades ago. This lecture will provide an update on new insights into dinosaur evolution and set out some of the prospects for future research.

Professor Malcolm Grant sets the scene for the new academic year by reflecting on the challenges facing universities and how UCL is uniquely placed to engage with the major issues of our times.

To celebrate the 400th Anniversary of the telescope and World Space Week. Dr Bridle will describe in pictures ‘gravitational lensing’, the bending of light by gravity, which is predicted by Einstein’s General Relativity. The mysterious dark components that constitute most of the universe do not emit or absorb light, but they do exert a gravitational attraction, and gravitational lensing is one of the most promising methods for finding out more about them. Dr Bridle will review the current observations and upcoming surveys.

Can we use evidence from the social epidemiology carried out in previous times to help us predict the likely effect of the present recession on public health? Mortality in unemployed men in the 1970s and 80s was around 30% higher than average. However, the 1980s saw a rapid increase in life expectancy in the population as a whole. Professor Bartley argues that we can now use evidence from longitudinal studies to understand the complex impact of recession on public health.

To mark World Mental Health Day – 10 October. Professor Bebbington explores the idea that psychiatry has an essentially social component because the phenomenon it seeks to explain have inherently social attributes. Psychiatric symptoms relate to our internal experience of external reality, and therefore comprise elements of both the internal and external world. A full account of psychiatric disorder must invoke the interaction of biological and social factors, acknowledging that the balance between these factors will vary between individuals.

Celebrating the 100-year anniversary of Selma Lagerlöf – the first woman to win the Nobel Prize for Literature – 10 December. Swedish author Selma Lagerlöf (1858-1940) was the first woman to win the Nobel Prize for Literature. Her novels inspired epoch-making early films, when she turned 80 she was one of the most widely translated Swedish authors ever, and her work continues to attract new readers today. This lecture gives a flavour of the range of her writing, looks at the explanations for her success and tests the findings of more text-focused scholarship.

This lecture discusses how genuine freedom must include all manner of thought, including the irrational, the bad, and the obscene, and how the recent new offence of possessing extreme pornography has breached this principle.

Dr Armstrong will discuss the potential of ‘metabolic materials’ that possess some of the properties of living systems. By generating such materials it is hoped that our cities will be able to replace the energy they draw from the environment, respond to the needs of their populations and eventually become regarded as ‘alive’ in the same way we think about parks or gardens. Metabolic materials could become a key sustainable technology with the potential to transform the world’s urban environments.

Samuel Johnson’s Dictionary of the English Language taught the British how to spell, established Shakespeare as their greatest writer and provided the first and longest lasting map of the English language in all its subtlety and variety. This lecture will tell the extraordinary story of how the first dictionary was made and take you inside what has become the least well known great book in our literature.
