Whether you are human or computer, viruses can ruin your day, so taking steps to avoid them is important. This lecture will ask whether there are similarities between human immunity and computer immunity? Can we use discoveries in one system to help protect against infections in the other? Might we one day take our laptops for regular vaccinations, or run a ‘software update’ on our own immune systems to avoid an emerging pathogen?

How have lawgivers featured in modern revolutions? This lecture considers key moments in revolutions, including seventeenth-century Britain, eighteenth-century France and (what would become) the United States, and twentieth-century Iran. The appeal to lawgivers (including ancient ones from many cultures) in revolutionary visions and in consolidating new constitutions is a striking feature of modern politics.

The U.S. Constitution had to be formed through debate before it could be ratified. Mirroring this, a British constitution must emerge through debates held by the next generation. This lecture indicates schools are a good environment to foster this. For students, there are many contentious issues that tap into discussions at the heart of writing a constitution. Students being punished for swearing raises questions of limits to free speech. Students wishing to intervene when an unpopular peer is bullied would be empowered by constitutional duty obliging them to do so. Schools tend to be authoritarian institutions, benevolent or otherwise, and can either provoke students to develop ideas on power structures and recognise the need for their own rights and duties, or condition them to accept of the status quo.

The JWST is the most expensive and powerful telescope astronomers have ever constructed. Its launch in 2021 started a new phase in our exploration of the cosmos, with the observatory's golden mirrors producing instantly iconic images of the Solar System's giant planets, nearby star-forming regions and galaxies, and our distant universe. The lecture includes the latest news from its studies of the early universe, a place lit up by what appears to have been a much more spectacular burst of activity than anyone expected.

Why do smart people make dumb financial choices? This lecture explores the surprising link between our psychology and money mistakes. We will see how fear, overconfidence, and even our desire to be liked can cloud our judgment, especially when dealing with financial "experts". Learn how these psychological blind spots worsen conflicts of interest, and how to make smarter financial decisions, free from emotional influence.

Throughout history, authorities have struggled to manage individuals’ urges to speak out against injustice and malpractice. IT has given us new means to obtain and publish data that others may wish to protect or even conceal. To some, those who hack and leak are heroes. To others, they are criminals. In an era of mass leaks and high-profile whistleblowing, who decides whether data thieves and hackers are to be protected or prosecuted? And are the old rules still fit for purpose in the digital age? This lecture will discuss these questions and will consider the moral case for stealing data.

This lecture delves into musical forms which rely on the most economical of materials and concepts. From Steve Reich’s adoption of rhythmic cycles and phasing in Ewe drumming to the expressive power of Estonian composer Arvo Pärt’s music, we explore how profound effect can emerge from such apparent simplicity. This lecture unpacks the processes behind celebrated minimalist works and reveals the quiet and elegant mechanisms underpinning their musical power.
