normal as far as i know has many meanings in mathematical and physical terms.
Normal is the line that is perpendicular to the tangent of a curve.
A surface normal, or just normal to a flat surface is a three-dimensional vector which is perpendicular to that surface. A normal to a non-flat surface at a point p on the surface is a vector which is perpendicular to the tangent plane to that surface at p. The word normal is also used as an adjective as well as a noun with this meaning: a line normal to a plane, the normal component of a force, the normal vector, etc.

"Normal", is usually used in optics. It is a line perpendicular to a reflecting or refracting surface.

Normal is the perpendicular line at a point in a given plane area.

Perpendicular.
Of course, if you use this definition at a party, your friends won't think you're normal. No matter, most of them probably aren't normal to the floor, anyway.
Anyone who knows as many definitions for normal as visibleman is, by definition, not normal. lol

wide-spread - boring and familiar. Love - difficult to define however the closest i will come is you're prepared to settle for the failings of yet somebody else and positioned them earlier your self, to never enable them to bypass, to be happy once you're with them Confusion - Um....DARHAR

"Normal," is seen from the perspective of individuals, who use themselves as the standard. For instance, you think differently than I do...therefore, from my perspective, I am normal and you are not. I think this pretty much applies to everyone.
