Over a single weekend in 1869, a young Russian chemistry professor named Dmitri Mendeleev invents the Periodic Table, bringing order to the growing gaggle of elements. But this sense of order is shattered when a Polish graduate student named Marie Sklodowska Curie discovers radioactivity, revealing that elements can change identities — and that atoms must have undiscovered parts inside them.

Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.

Ice is one of the strangest, most beguiling and mesmerising substances in the world. Full of contradictions, it is transparent, yet it can glow with colour, it is powerful enough to shatter rock, but it can melt in the blink of an eye. It takes many shapes, from the fleeting beauty of a snowflake to the multimillion-tonne vastness of a glacier and the eeriness of the ice fountains of far-flung moons. Science writer Dr Gabrielle Walker has been obsessed with ice ever since she first set foot on Arctic sea ice. In this programme, she searches out some of the secrets hidden deep within the ice crystal to try to discover how something so ephemeral has the power to sculpt landscapes, to preserve our past and inform our future.
