The Magnetic Resonator Piano invented by Andrew McPherson sees electromagnets suspended above the strings of a regular grand piano, allowing for control of minute details of shimmering resonance.
Were the Crusades an early example of European colonialism? What value did the crusading frontier hold for the knights who fought to defend it? What was the relationship between the Crusades and the knightly culture of chivalry?
In this talk Dr Sheila Kanani combines the story of a pioneering woman astronomer, with an account of the science behind comets, asteroids and meteors.
When black holes merge, the world shakes. Such quakes in space-time are now detectable and indeed the detection of such gravitational waves from cosmic coalescences comprises an entirely new type of astronomy that is completely independent of light itself.
Space today is terrifyingly silent. But it wasn’t always thus: the early universe was filled with a hot plasma in which sound waves could travel. The cosmos was quivering with the aftershocks of the Big Bang.
Cyberwar is not waged on physical battlefields following rules of engagement. Aggressors worry less about collateral damage, in part because they aren’t forced to confront the sight of an enemy bleeding to death before their eyes.
Highly energetic particles from outer space travelling at the speed of light, known as cosmic rays, originate from the sites of extreme particle acceleration in the Universe.
When light is dispersed into its constituent colours, it can become possible to discern rich dynamical information about an evolving system in space, for example cosmic explosions, collisions or accelerations.
In 1930, the great physicist Wolfgang Pauli invented a new particle to save the principle of energy conservation in certain radioactive decays he was studying.
