How Does Mathematics Last? Heritage and Heritage-making in Mathematics

How is mathematical knowledge recorded and preserved across generations? Contrary to the idea that mathematics itself is somehow ‘permanent’, this talk explored heritage-making in mathematics, that is, the people, institutions, and material objects that can give mathematical ideas longevity. It explored the heritage-making found in two very different types of French nineteenth-century libraries: those of […]

Asteroid Adventures

Asteroids were for years considered ‘celestial vermin’ – objects which got in the way of more interesting fodder for astronomers. Now, they are central to our Solar System’s story, the building blocks from which planets are made, and capable of telling us the history of the last five billion years. This lecture considered two missions […]

The Biggest Cosmic Map

Mapping the stars is, perhaps, the oldest of astronomical pursuits, but it has been perfected by the European Space Agency’s Gaia mission. The exquisitely precise map it provides shows the positions and movements of the nearest two billion stars. Starting with a history of mapping the cosmos, this lecture outlined the new and dynamic history […]

Come With Me Inside a Black Hole

What happens if you fall into a black hole? In this mind-expanding lecture, Carlo Rovelli, world-renowned physicist and bestselling author, took us on a journey inside a black hole—exploring time dilation, the warping of space, and the potential for black holes to transform into white holes. From Einstein’s equations to the cutting edge of quantum […]

Touching the Sun

Despite its familiarity, the Sun is a very different presence from the friendly yellow circle in children’s paintings. Our star is a broiling mass of plasma, with its powerful magnetic fields, twisted by its rotation, capable of producing dramatic events of spectacular beauty and power. Using results from NASA’s Parker Solar Probe – the fastest […]

Black Holes and Bangs

Space itself is wobbly. We exist on a choppy sea, its surface roiled by disturbances caused by the movements of black holes hundreds of millions of light-years away. The recent detection of these ‘gravitational waves’ by a completely novel type of observatory is a story of scientific persistence and precision engineering, resulting in a completely […]

A Mathematician’s View of Proof

The idea of proof is fundamental to mathematics. We could argue that science consists of testable theories, and therefore that it is about what can be disproved, not what can be proved. In law, the test is “beyond reasonable doubt”. Famous conjectures in mathematics have been tested by computers for trillions of numbers – but […]
