Parabolas (artwork)
Parabolas 3D Printed Plastic, 10 in 2019

This artwork depicts a small sample of the infinite number of parabolas that pass through three points. It is based on a recent paper ("All Parabolas through Three Non-collinear Points" by Huddy and Jones; Mathematical Gazette 102, July 2018, 203-209). Three control points are rotated around the \(z\)-axis resulting in three rings. A parabola exists with an axis of symmetry at every angle \(\theta\) in the range 0 to \(\pi\) except the three where a pair of the control points are co-linear. The parabola with an axis of symmetry at an angle \(\theta\) is associated with a parabola in the sculpture in the \(xz\)-plane rotated around the \(z\)-axis by an angle twice \(\theta\).
