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?

Cosmic Vision: Witnessing Fireworks

Accounts of occasional celestial spectacular events in past centuries have provided crucial information for modern-day astrophysicists. One such example is the so-called Great Eruption of Eta Carinae which was for a time in the mid 19th century the third brightest object in the night sky.

Cosmic Vision: Attentive Eyes

Well-trained eyes can be remarkably useful for capturing light curves of evolving objects in the cosmos, even contributing to modern research programmes.

Cosmic Vision: Watching the Radio

At longer wavelengths than the normal optical wavelengths to which human eyes are normally sensitive, is the radio part of the electromagnetic spectrum.

Looking for Life On Mars

Mars has changed since it formed 4.6 billion years ago. When life started on Earth ~4 billion years ago, Mars was habitable too, with volcanism, a magnetic field, surface water and a thick atmosphere. Today, Mars is cold and dry, with a thin atmosphere and harsh surface.

BBC Radio in the 78 Era (1920–1948)

Perceptions, Expectations, and Discoveries

This talk will consider how expectation plays a role in discovery and in scientific advance, and considers the challenges involved in assessing changes taking place on our own planet.

Mysteries of the Dark Cosmos

This lecture will present the endeavours of cosmologists and particle physicists, as they attempt to explain the fundamental nature of these mysterious dark components.

Engineering: Archimedes of Syracuse

In the 3rd century BCE, the Sicilian polymath Archimedes significantly advanced human understanding of mathematics, geometry and astronomy.

Simple Laws, Spectacular Astrophysics

This talk will examine why laws are simple and how the combination of simple laws can lead to rich complexity.
