Gresham College Lectures

This lecture explores the very limits of music: investigating historical efforts to catalogue musical materials including the melacarta of Carnatic music, the wazn of Arabic maqam, Slonimsky’s Thesaurus of Scales and Melodic Patterns, Schillinger’s Encyclopedia of Rhythms, Forte numbers, and contemporary attempts to ‘pre-copyright’ every possible melody yet to be written.

It also tackles the bigger questions: how much music might exist, whether it ever will be exhausted, and if there are any boundaries of our musical perception and imagination.

This lecture was recorded by Milton Mermikides on 16th May 2024 at LSO St Luke's Church, London

Starring in My Fair Lady (1956), The Sound of Music (1965) and Cinderella (1957) gave Dame Julie Andrews unparalleled profile.

These were among the most successful Broadway, Hollywood and TV musicals of their time. Yet following this golden decade, she made few films and appeared in no Broadway shows during her forties and fifties, typically an artist’s most productive period.

How did she then become one of the most revered female stars of the late twentieth century?

Weather and climate-related events can cause significant mortality and disability.

Sudden cold, heat, storms and floods all present risks to health, especially to the most vulnerable. Even in countries with temperate climates like the UK, weather-related deaths can be in the thousands, for example cold snaps causing cardiovascular deaths. In countries with more extreme weather this can be much greater. Some can cause major social disruption.

This lecture considers how weather events cause harm to health, and our countermeasures.

In this lecture I will show you some mathematical illusions: “proofs” that 1=0, that fractions don’t exist, and more. There are curious and important implications behind what’s going on.

These “proofs” reveal some very common logical slips that can go unnoticed when we are trying to prove more plausible statements. And the stakes are high. As I’ll show you, once you have “proved” one false claim, you can prove absolutely any statement at all.

Evolution has led from amoebae to blue whales and from algae to giant redwoods. 

So what might it do in the future? What species might evolve in the next ten million years? How will evolutionary processes change as a result of human innovation and what are the risks of us getting it disastrously wrong? What might evolution look like if we ever set up home on another planet, or if inhabitants of other planets arrive here?

Come take a ride in the Tech Time Machine and explore how IT may change our lives in the next fifty years. By employing techniques used by science fiction writers, we can imagine how Artificial Intelligence, extended reality, mobile connectivity, quantum computing, and others will develop.

How will they converge, enable and accelerate each other? We can anticipate the opportunities and challenges technology may bring. Why should we fear disruption? Should we instead embrace it?

What makes a piece of music challenging, bland, intriguing, beautiful or ugly?

This lecture explores the concept of ‘musical flavour’ formed by intervallic, rhythmic and timbral components and how they contribute to a sense of consonance and dissonance.

In particular we look at the interval vector, a system by which harmonic objects are analysed as a series of ‘handshakes’ between pitches, providing a measure of harmonic ‘bite’. The ‘Hendrix chord’ is used as a case study of such harmonic flavour.

Boyajian's star, a faint and unprepossessing presence in the constellation of Cygnus, attracted astronomers' attention when it began to flicker alarmingly.

We will discuss explanations for its behaviour, from disintegrating comets to alien megastructures, and consider how modern astronomy hunts for the truly unusual objects in the Universe.

For this task, the involvement of large numbers of volunteers - citizen scientists - is essential, for example via the Zooniverse platform, which invites you to participate in classifying galaxies and discovering planets.

This lecture makes a survey of learned ceremonial magic in Europe throughout history and demonstrates that both of the customary claims made for it by practitioners since the Middle Ages are actually correct: that there is a continuous tradition of it and that it is ultimately derived from ancient Egypt.

In doing so, it also shows what is distinctive about Western magic.

Queer urban life has changed dramatically in England over the last seventy years. Shifts in the economy, culture, attitudes, and technology have all played their part in this. London has often been used as the barometer for these shifts, suggesting they were experienced in similar ways across the nation.

In an exploration of the queer contours of Leeds, Manchester, Brighton and Plymouth, this lecture takes issue with this assumption and shows how and why LGBTQ scenes, communities and identities could feel very different from place to place.
