1 de nov. de 2016 · A nonic surface is one defined by a polynomial equation of degree 9. This image by Juan García Escudero shows a nonic surface called \(Q_9\), which has 220 real ordinary double points: that is, points where it looks like the origin of the cone in 3-dimensional space defined by $$ x^2 + y^2 = z^2 .$$

15 de feb. de 2016 · This animation by Greg Egan shows 27 lines on a surface defined by cubic equations: the Clebsch surface. It illustrates a remarkable fact: any smooth cubic surface contains 27 lines. In its most symmetrical presentation, the Clebsch surface is defined by the equations. x0 + x1 + x2 + x3 + x4 = 0 x3 0 + x3 1 + x3 2 + x3 3 + x3 4 = 0.
