A podcast about the big numbers, the hard sums, the mathematics that defines, runs, shapes, changes, begins, ends, every things our lives and the world around us. Hosted by Colm O'Regan. An award-winning radio broadcaster, comedian, novelist and it turns out lapsed engineer who is trying to feel useful again. Each episode sheds light on a tiny corner of a giant subject with entertaining guests and accessible talk.Themes and summary (AI-generated based on podcaster-provided show and episode descriptions):
➤ accessible maths and big numbers • statistics in sport, crime, census, voting • algorithms, AI, bias, big data • energy, climate, carbon, degrowth modelling • physics/astronomy: black holes, pulsars, quantum computing • measurement, puzzles, symmetry, origamiThis podcast uses mathematics as a lens for understanding how the world works, pairing an accessible, conversational style with guests from science, engineering, data, and culture. Across the episodes, the host explores “big numbers” and practical models that sit behind everyday systems and headline issues, often translating technical ideas into stories, metaphors, and real-world examples.
A major thread is how societies measure, count, and make decisions: the statistics behind censuses and crime, the design and consequences of voting systems, and how data can mislead through bias, flawed incentives, or algorithmic opacity. Listeners also encounter applied maths in public-policy problems such as housing, carbon pricing, energy transitions, and climate modelling, with attention to uncertainty, optimisation, and the limits of forecasts.
Another recurring focus is computation and modern technology, including AI tools, algorithm audits, networks and matrices, and the promise and risks of quantum computing. The show frequently connects maths to physical science—from weather prediction and ocean systems to astrophysics, black holes, pulsars, and chaotic dynamics—highlighting how models are built and what evidence can (and can’t) establish.
Alongside these big themes, the podcast dips into the human side of maths: how people learn it, communicate it, and find it in art, puzzles, origami, literature, film, sport analytics, and even the history of calculators and measurement standards. Overall, it’s a wide-ranging tour of mathematical thinking in culture, nature, and modern life.
