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 in everyday life • Statistics in sport, elections, crime, census • Algorithms, AI, bias, data • Physics/astronomy: black holes, pulsars, quantum computing • Climate, energy, carbon modelling • Measurement, puzzles, educationThis podcast uses mathematics as a lens for understanding how the world works, moving fluidly between big scientific ideas and everyday systems that generate data and demand decisions. Hosted by Colm O’Regan, it is structured as accessible conversations with researchers, writers, educators, and technical experts, with a recurring emphasis on “big numbers,” model-building, and the hidden assumptions behind calculations that shape modern life.
Across the episodes, a major theme is how maths underpins public systems and collective choices. Listeners encounter the logic of elections and voting rules, the design and interpretation of censuses, and the role of statistics in criminology and perceptions of safety. Related discussions explore algorithmic decision-making, bias in automated systems, and how data audits and measurement choices can change outcomes in technology, media, and governance.
Another through-line is modelling complex natural phenomena and the physical world. Topics include climate and weather forecasting, energy systems and the transition away from fossil fuels, carbon accounting and optimisation, and the mathematics used to estimate future demand. The show also ventures into space and fundamental physics, touching on astrophysics, black holes, quantum computing, and the mathematical tools used to interpret large datasets or describe chaotic systems.
The podcast frequently connects mathematical thinking to culture and communication: maths in films, links between mathematics and literature, and approaches to teaching and popularising the subject—from mental arithmetic and estimation to puzzles, symmetry, origami, and children’s maths media. Historical and “why we do it this way” perspectives appear as well, including measurement standards and the evolution of everyday technologies like calculators.
Overall, the content emphasizes curiosity-driven explanation: what a concept means, where it appears in real life, what it can and can’t tell us, and how quantitative reasoning intersects with human behaviour, incentives, and uncertainty.
