At the age of 19, in 1657, he gave the first rectification of the semicubical parabola.

In and we considered tangential families with singular support (the singularity being a semicubic cusp).

The vacuum ﬁeld noise of semicubical parabolas can be ﬁtted by a Wien-type spectrum, the radiometric parameter then corresponding to both curvature and torsion.
Noninertial quantum mechanical fluctuations
It is convenient to represent Legendrians by their front projections to the xz plane, which are (a collection of ) oriented closed curves with no vertical tangencies, whose only singularities are transverse double points and semicubical cusps.
