On Earth, plant scientists have conducted many experiments to try to unravel the apparently simple responses of plants to the Earth's gravity. The basic problem is how to modify the amplitude of gravity so that developmental responses under different gravitational force levels can be studied. On of the earliest experimental devices for approaching this problem was to rotate material as Knight 1806 has done, but oriented horizontally on the periphery of a disc rotating in a vertical plane see...
