Misha Glenny and guests discuss a turning point in world affairs in 1898 that left Spain greatly reduced as an imperial power and the US the owner of the Philippines, Guam and Puerto Rico, with a significant influence over the newly independent Cuba where the war broke out. The U ...  Show more

Misha Glenny and guests discuss the physics, biology and chemistry of the element silicon which is at the heart of some of the most useful and beautiful objects on the planet. While it is still being created throughout the universe, the silicon we have here was made billions of y ...  Show more

If superconductors — materials that conduct electricity without any resistance — worked at temperatures and pressures close to what we would consider normal, they would be world-changing. They could dramatically amplify power grids, levitate high-speed trains and enable more a ...

Few topics have captivated the imagination of scientists like superconductivity. In this episode, we cover the history of superconductors starting with the Gentleman of Zero Kelvin himself. We discuss applications of superconductors for high-speed trains and more and even chat ...

Melvyn Bragg and his guests discuss the science of matter and the states in which it can exist. Most people are familiar with the idea that a substance like water can exist in solid, liquid and gaseous forms. But as much as 99% of the matter in the universe is now believed to exi ...  Show more

Melvyn Bragg and his guests discuss dark matter, the mysterious and invisible substance which is believed to make up most of the Universe. In 1932 the Dutch astronomer Jan Oort noticed that the speed at which galaxies moved was at odds with the amount of material they appeared to ...  Show more
