The smaller the scales we want to look at, the bigger the tools we need to use, and with complex equipment of this magnitude, it is becoming more and more common for research groups to share central user facilities. Focusing on UCL's use of central user synchrotron radiation facilities (sub-atomic particle accelerators), this lecture will highlight developments in the 3D imaging of nanomaterials in the ultimate quest for creating better medical sensors.

To mark Brain Awareness Week, Dr Mark Lythgoe will take audiences on a journey in search of the greatest brain of the 20th century, a brain which was removed during the autopsy of Einstein in 1955. Through this journey, Dr Lythgoe will then discuss whether Einstein’s brain was extra special, and what this research can tell us about genius. Finally, this lecture will then take a playful look at whether we all have the potential to unlock our creative mind.

We hear a lot about the stresses of juggling motherhood with paid work, and the subsequent harm this might cause children. However, this lecture to mark International Women’s Day discusses evidence from UK cohort studies following generations of men and women which suggests that working mothers not only end up healthier in mid-life, but that their daughters may also end up happier too.

The public debate about patents is old and never stops. Here is what Jeremy Bentham said:

“So long as men are governed by unexamined prejudices and led away by sounds, it is natural for them to regard Patents as unfavourable to the encrease of wealth. So soon as they obtain clear ideas to annex to these sounds, it is impossible for them to do otherwise than recognize them to be favourable to that encrease: and that in so essential a degree, that the security given to property can not be said to be compleat without it”

This lecture will put the debate in modern context and show why Bentham was right.

Parodied almost as soon as it was announced, and generally regarded as a topic beneath the remit of serious literary criticism, the Great American Novel enterprise has proved more durable and more various than almost any other in American literary culture. It remains the bench-mark for literary ambition, prestige, and sales. This lecture, to mark World Book Day, will consider some of the forms the Great American Novel has taken in its 150-year history and ask what social, political, moral, commercial and aesthetic needs it so persistently promises to serve.

This lecture marks World Book Day, 1 March 2012

More than two thousand years ago, Euclid of Alexandria wrote the most successful textbook of all time. Starting with a few simple assumptions (often called axioms), he proved one result after another — for example that the angles of a triangle add up to 180?. Scholars wondered whether the last of his five axioms — which referred to parallel lines, and sounded more like a theorem than an assumption — wasn't simply a necessary consequence of the other four. Many tried to prove this, and some false proofs were published. I shall give a very convincing one before outlining the history of geometry up to the nineteenth century. That's when three people independently discovered a perfectly consistent geometry in which the Euclid's fifth axiom is not true, and where the angles of a triangle no longer add up to 180?. This new work inspired others and led eventually to the sort of geometry Einstein needed for his theory of gravity.

An individual’s risk of Coronary Heart Disease is currently based on classical risk factors such as age, gender, blood pressure, smoking habits and obesity. However, most heart attacks occur in individuals with only average classical risk factors. In this lecture, Professor Humphries will discuss how family history of Heart Disease is also an important predictor, and how identifying specific genes and DNA variants within family history could help doctors offer lifestyle and drug advice to individuals. This lecture with then focus on the need for researchers to explore different ways of presenting information about genetic risk, to find approaches that minimise a sense of fatalism and maximise motivation for behaviour change.

Almost three tons of concrete are produced every year for each man, woman and child on the planet. It is now second only to water in terms of human consumption. Yet how has the astonishing take-up of this new medium within little over a century been accommodated into our mental universe? While it has transformed the lives of many people, in Western countries it has been widely vilified, blamed for making everywhere look the same, and for erasing nature. Architects and engineers, although they have primary responsibility for 'interpreting' concrete, are not the only people to employ the medium, and many other occupations - politicians, artists, writers, filmmakers, churchmen - have made use of concrete for purposes of their own. The results are often contentious, and draw attention to the contradictions present in how we think about our physical surroundings.

In 1825 a group of liberal politicians, lawyers, dissenting ministers, Roman Catholics, and Jews came together to found a university in London aimed at those excluded from the two old-established English universities, where teachers and students were required to be subscribing Anglicans. To mark the anniversary of UCL’s foundation on 11 Feb 1826 this lecture will look at the opposition to the new university among Tory politicians and journalists, especially in the ultra-Tory paper John Bull, which nicknamed the new institution 'Stinkomalee' in honour of the swampy rubbish dump on which the building was constructed between 1826 and 1828.

This lecture investigates one of Dickens's most peculiar and enigmatic characters, Master Humphrey, the narrator of The Old Curiosity Shop (that is, until he is mysteriously dismissed from this role). It details some of Humphrey's oddities, and speculates about his puzzling past, before discreetly following him into the streets of London at night. It identifies him as a far more disturbing individual than readers of this supposedly sentimental novel tend to assume, and locates his unsettling descendants in novels by Stevenson, Joyce and Nabokov, among others. (This lecture marks the 200th anniversary of the birth of Charles Dickens)
