Invisible vs. Transparent (Score 1)

How can they create something that's invisible, when they don't even know the difference between invisible and transparent? I know, maybe my knowledge and undestanding of these two concepts differs from you english people, but "Invisible" only means material or object, that does not reflect light at all. Transparent means material or object, that does reflect light, so the eye believes there is nothing there. I do understand the "philosophical" flaw of my point of the view. If object does not reflect light, eye can tell where and by the shape of the object, what it is, therefor making it less invisible. But even if your brain can add things up and tell you things about the object, the object itself remains invisible..so there is no flaw.
