Why does it matter that the Sun's core rotates faster than the surface?

New research has found that the Sun spins at different speeds. Stephen Serjeant explains why that's important.

Motion under gravity

From the moment that Galileo dropped two cannonballs of different sizes and weights from the top of the Leaning Tower of Pisa mankind has been fascinated by the impact of gravity. This free course, Motion under gravity, looks at gravity, its impact on objects and how the energy involved in the movement of objects is dispersed or stored.

Predicting Volcanoes

The Open University's researcher in volcanoes, Hazel Rymer explains why the Poás volcano in Costa Rica is her favourite, and how evidence form previous experiments there has lead her to believe there may be an environmental crisis - similar to one in the 1990's - on it's way. There have been changes in gravity above Poás, and Hazel talks us through some experiments she will be undertaking in the future.
