Most mathematicians are familiar with the definition of one's Erdös Number. Paul Erdös, the Hungarian mathematician of the highest caliber, wrote hundreds of papers in many different areas, many in collaboration with others. His Erdös number is zero. His co-authors have Erdös number one. People other than Erdös who have written a joint paper with someone with Erdös number one but not with Erdös himself have Erdös number two, and so on. See the Collaboration Graph of some famous mathematicians. The Erdös Number Project Web site gives much information about all this.

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 lenght six are:


0. Paul ERDÖS 1. Harold Nathaniel SHAPIRO 2. Richard Ernest BELLMAN 3. Ramabhadra VASUDEVAN 4. Ramaswamy JAGANNATHAN 5. Sameen Ahmed KHAN	0. Paul ERDÖS 1. Wladimir P. SEIDEL 2. Robert Eugene MARSHAK 3. Ennackal Chandy George SUDARSHAN 4. Rajiah SIMON 5. Sameen Ahmed KHAN
0. Paul ERDÖS 1. Lee A. RUBEL 2. Willard MILLER, Jr. 3. Charles P. BOYER 4. Kurt Bernardo WOLF 5. Sameen Ahmed KHAN	0. Paul ERDÖS 1. Ronald Lewis GRAHAM 2. Hans Julius ZASSENHAUS 3. Jiri PATERA 4. Joris VAN DER JEUGT 5. Ramaswamy JAGANNATHAN 6. Sameen Ahmed KHAN

Einstein Number of KHAN Sameen Ahmed KHAN

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. Albert EINSTEIN
1. Valentine BARGMANN
2. Marcos MOSHINSKY
3. Kurt Bernardo WOLF
4. Sameen Ahmed KHAN

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”). 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.
