This talk was recorded at the Ri on 9 October 2023.
These models observe the spectro-photometric and mass properties of galaxies, and have found widespread applications in astrophysics and cosmology, providing us with the tools to study galaxy formation and evolution both theoretically and through data interpretation.
Claudia will explore how Stellar Population Models are developed, using leading-edge techniques to predict the properties of stars and their evolution over time. You'll discover how these models are used to study the formation and evolution of galaxies, shedding light on the mysteries of the Universe and its origins.
Whether you're an astrophysics enthusiast or just curious, this talk promises to be a fascinating journey through one of the most exciting fields in modern science. So, join us as we unravel the secrets of the cosmos and explore the frontiers of our understanding of the Universe.

But quantum science is one of the least diverse areas of science in terms of gender and other protected characteristics.
Jess Wade, a physicist and lecturer in functional materials at Imperial College London, has been fighting the inequality in quantum physics and beyond by creating thousands of Wikipedia pages for women scientists. Jess joins us this month to discuss the past, present, and future of quantum science along with what can be done to increase diversity within the field.

Life grows up in the universe by gradual degrees of evolution. Billions of years ago, there existed a vast population of bacteria. But it was only an elite group of these bacteria that evolved to become humans. In truth, we are lucky to be alive.
In the first of his CHRISTMAS LECTURES, Richard Dawkins explores the origins of life. Beginning with a look at our ancestry, he shows how the probability of our existence is very small. Becoming an ancestor is much more difficult than simple reproduction, and Richard reveals how our ancestors did what it took to survive and pass on their genes.
But although some of our life must be devoted to perpetuating it, surely there must be more to it? Richard explores the role of art and culture in society, and examines how the capabilities of the human body have enabled us to accomplish complex tasks.
When it comes to our understanding of the meaning of life, science is important. As Richard explains, science can help us uncover both when we arrived on this planet, and why we are here. Some people turn to the supernatural for the answer to such questions. Richard looks at the limitations of beliefs in the supernatural and uses a cannonball to prove why instead we should have faith in science and its predictions.

About the 1991 CHRISTMAS LECTURES
The world-famous evolutionary biologist Richard Dawkins presents the CHRISTMAS LECTURES on "our own growing knowledge of how life grows up in the universe."
Just as children grow up to be adults, so too does life gradually evolve on a planet over thousands of generations, to move from “nonliving simplicity” to become “living complexity”.
Combining beautiful writing with a range of illuminating demonstrations, the series featured a variety of wildlife, a virtual reality Lecture Theatre, and special guests – including the late Douglas Adams reading an excerpt from The Hitchhiker's Guide to the Galaxy.
