The final lecture in the series returns to the theme of how insight is derived from observations, considering the cosmic microwave background.

This oldest light in the Universe, emitted just 400,000 years after the Big Bang, contains the seeds of the structures we see around us, and tells us about conditions at the Universe's beginning.

It will also consider how measurements of the Universe's expansion, made using the CMB, are leading to unexpected results, creating tension in modern cosmology.

This lecture traces the history of race and disability law in the English education system. It examines the impact of discriminatory policies on Black children, children of colour, and disabled children, and how narratives around race and disability have changed.

The lecture questions why inequality persists and explores possible solutions.

Logarithms were perhaps once thought of as just an old-fashioned way to do sums on slide rules. But they underpin much of modern life, from modelling the COVID pandemic to Claude Shannon’s mathematical theory of information (which makes mobile phones a reality) and making sense of Cristiano Ronaldo’s crazy Instagram follower numbers.

This lecture will explore the basics and history of logarithms, and then show how they are a natural way to represent many models and datasets.
