 The objective was to investigate possible changes over time of the characteristics of the motion, hypothesized to yield information about asymmetries of inertial space (sometimes described as "aether flow").The defining feature of the "paraconical" or "ball-borne" pendulum is that the pendulum is carried upon a ball which rests upon a flat, thus permitting it to rotate about its vertical axis as well as swinging in two perpendicular directions.Therefore a paraconical pendulum has three degrees of freedom.
