The more widely used meaning...
This possibly brings new meaning to the term "more widely". OED word of the day.
eikonal, n. and a.
A. n. The optical path length of a ray between specified points in the object and image spaces; more widely, a function of position denoting the time taken by a wave-front to reach a specified point.
B. adj.
1. Physics. Designating an equation which expresses the eikonal in terms of the wave velocity.
2. Particle Physics. Of, pertaining to, or designating a method of approximating the behaviour of particles by the use of eikonals.
I can see I'll have to use that word more often: but only with the "more widely" used meaning, of course. Wouldn't want to be obscure.
