A world of conics

Do you think you know everything about conics? This feature aims to surprise you. Change your point of view – in the literal sense – and the familiar parabola or circle become unrecognizable. Abandon the 'as the crow flies' distance of the Euclidean plane for another metric, and conics transform into strange creatures you wouldn't have imagined. In the real world, architects and engineers have made conics their most faithful, and most discreet, allies. And in the sky, Kepler's three laws, the foundation on which Newton built universal gravitation, continue to govern the motion of celestial bodies. Conics, it seems, are everywhere.
