    The Mathematics of Bell Ringing

    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?

    Data: The Past, the Present and the Future

    Data structures are the critical ingredient of all good information systems. Poor data structures lead to horrendous problems of interoperability and nightmarish complexity; good ones can make the ‘uncomputable’ computable.

    Understanding the Universe with AI

    Over the last 30 years, digital technology produced an exponential increase in astronomical data. Within our lifetime, the entirety of the visible universe will have been mapped out: we will have seen everything there is to see. The question will then be: what does it all mean?

    The Sound of Mathematics

    It has been known since antiquity that there are simple “harmonic” relationships between notes that sound appealing together. This lecture introduces the mathematics of pitch, scales, and just temperament. The pitch of a sound is not its only important property.

    Reserve Currencies in the Era of Fiat Money

    This event, jointly hosted with the British Society for the History of Mathematics, will focus upon the relationship between mathematics and money, from coinage through to cryptocurrencies.

    Cryptocurrencies: Protocols for Consensus

    This event, jointly hosted with the British Society for the History of Mathematics, will focus upon the relationship between mathematics and money, from coinage through to cryptocurrencies.

    Thomas Harriot on the Coins of England

    This event, jointly hosted with the British Society for the History of Mathematics, will focus upon the relationship between mathematics and money, from coinage through to cryptocurrencies.

    An Introduction to Algorithms

    Algorithms, loosely translated, are systems for doing things. Algorithms are thus the link from pre-history to the modern world – without algorithms we would have an inanimate universe without all the mess and complexity of real life. It turns out that the history of algorithms is messy.

    The World of Isaac Newton

    This illustrated lecture will cover Newton's life and his mathematical and scientific labours in the context of 17th-century England.
