Yeah but I hear people bastardize things all the time, just to use the the "cool" new technical term. I have even heard supervisors say: "I want to see more fresnel on that object..." when what they really mean is that they want it to be more reflective.

As the rendering software starts to become better and better at recreating real world lighting, it is important that we use real world terminology, as you have pointed out. And while I come from a scientific background, as a lighting artist today, I find it more important to adapt to the same language that they use on set (in the real world). That means using the same language as they use in cinematography.... and the term Specular and Diffuse LIGHT are used all the time... and the term Shinny and Matte SURFACES are used all the time. Sometimes simple words give the best results. They are not as sexy, but there is a reason they have been around for so long. But that is just me, some people like to use more scientific terms such as caustics and fresnel, and those are valid too as long as they are used correctly.
