Roundworld is in trouble again, and this time it looks fatal. Having created it in the first place, the wizards of Unseen University feel vaguely responsible for its safety. They know the creatures who lived there escaped the impending Big Freeze by inventing the space elevator - they even...

The acclaimed Science of Discworld centred around an original Pratchett story about the Wizards of Discworld. In it they accidentally witnessed the creation and evolution of our universe, a plot which was interleaved with a Cohen & Stewart non-fiction narrative about Big Science. In The Science...

The fourth book in the Science of Discworld series, and this time around dealing with THE REALLY BIG QUESTIONS, Terry Pratchett’s brilliant new Discworld story Judgement Day is annotated with very big footnotes (the interleaving chapters) by mathematician Ian Stewart and biologist Jack Cohen...

In the 'fantasy' universe of the phenomenally bestselling Discworld series, everything runs on magic and common sense. The world is flat and million-to-one chances happen nine times out of ten. Our world seems different - it runs on rules, often rather strange ones. Science is our way of finding...

Based on new research conducted across Europe and in the United States, The Celts reveals when and how we came to call much of Europe "Celtic," why this idea mattered in the past, and why it still matters today, as the tide of nationalism is once again on the rise.

Roundworld, aka Earth, is under siege. Are three wizards and an orangutan Librarian enough to thwart the Elvish threat? When the wizards of Unseen University first created Roundworld, they were so concerned with discovering the rules of this new universe that they overlooked its inhabitants...

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.

What's the Use? asks why there is such a vast gulf between public perceptions of mathematics and reality. It shows how mathematics is vital, often in surprising ways, behind the scenes of daily life. How politicians pick their voters. How an absurd little puzzle solved 300 years ago leads to efficient methods for kidney transplants. How an Irish mathematician's obsession with a new number system improves special effects in movies and computer games. How SatNav relies on at least six mathematical techniques.

A bite-sized mathematical sightseeing tour of the natural world from the author of The Magical Maze. Why do many flowers have five or eight petals, but very few six or seven? Why do snowflakes have sixfold symmetry? Why do tigers have stripes but leopards have spots? Mathematics is to nature as Sherlock Holmes is to evidence. Mathematics can look at a single snowflake and deduce the atomic geometry of its crystals; it can start with a violin string and uncover the existence of radio waves.

Mathematician Ian Stewart tells listeners what he wishes he had known when he was a student. He takes up subjects ranging from the philosophical to the practical - what mathematics is and why it’s worth doing, the relationship between logic and proof, the role of beauty in mathematical thinking, the future of mathematics, how to deal with the peculiarities of the mathematical community, and many others.

Uncertainty is everywhere. It lurks in every consideration of the future - the weather, the economy, the sex of an unborn child - even quantities we think that we know such as populations or the transit of the planets contain the possibility of error. It's no wonder that, throughout that history, we have attempted to produce rigidly defined areas of uncertainty....

This compelling and compassionate mystery takes place in the quirky island town of Key West, Florida, where 21-year-old Jillian Dougherty, a newly graduated Boston nursing school student away from home for the first time, finds herself completely absorbed into the island's homeless population. Meet the island inhabitants that live under the bridges, behind the hedges, and on the edge of sanity in this tourist-island mecca.

Ian Stewart presenta las vidas extraordinarias y los sorprendentes descubrimientos de 25 de los mejores matemáticos de la historia, desde Arquímedes y Liu Hui hasta Benoit Mandelbrot y William Thurston. Sus sujetos son personas inspiradoras que han hecho contribuciones cruciales a las Matemáticas.

In this new season of History Reinvented we’ll uncover stories of Pine Camp. In the late 19th century, the 160 acres along the northern border of the city of Richmond was known as the City Farm or City Jail Farm. Later on, Richmonders who were battling contagious diseases, including smallpox and tuberculosis, were isolated on the property. But because this was the post Civil War South and the height of the Jim Crow era, only white patients were treated until eventually a separate house was built for the city’s Black population. When vaccinations were finally able to stem the diseases, ...

How can I get drivers to slow down in my neighborhood? What’s Vision Zero all about? Why does it take so long to get a sidewalk/bike lane or a reduced speed limit approved? Welcome to the Mechanics of Transportation – a podcast that will answer these questions as well as introduce you to people who you may want to share a bike ride, bus ride or walk with.Plus, there's a new sub-podcast called RVA Bike Scene in which Sean Yeager and I talk about local events and happenings in the Richmond Va bike scene.
