My own Erdös number is currently five. There are many paths of length five in my collaboration graph. Three such paths and another path of length six are:

Likewise we have the Einstein Number: Einstein's own Einstein Number is 0. His co-authors have Einstein Number 1. People other than Einstein who have written a joint paper with someone with Einstein Number 1 but not with Einstein himself have Einstein Number 2, and so on. My own Einstein number is currently four. One possible path is:
0.

Quadricmeter is the instrument devised to identify (distinguish) and measure the various
parameters (axis, foci, latera recta, directrix, etc.,) completely characterizing the important
class of surfaces known as the quadratic surfaces. Quadratic surfaces (also known as quadrics)
include a wide range of commonly encountered surfaces including, cone, cylinder, ellipsoid,
elliptic cone, elliptic cylinder, elliptic hyperboloid, elliptic paraboloid, hyperbolic cylinder,
hyperbolic paraboloid, paraboloid, sphere, and spheroid. Quadricmeter is a generalized form of
the conventional spherometer and the lesser known cylindrometer (also known as the "Cylindro-Spherometer"
and "Sphero-Cylindrometer").
With a conventional spherometer it was possible only to measure the radii of spherical surfaces.
Cylindrometer can measure the radii of curvature of a cylindrical surface in addition to the spherical
surface. In both the spherometer and the cylindrometer one assumes the surface to be either spherical
or cylindrical respectively. In the case of the quadricmeter, there are no such assumptions.
