I can recite that in my sleep. ;~> This is in contrast to the geometrical use of the word: "In geometry, an object such as a line or vector is called a normal to another object if they areperpendicular to each other. For example, in the two-dimensional case, the normal line to a curve at a given point is the line perpendicular to the tangent line to the curve at the point." Cheers!
