Science approaches SF

A serious article on the subject from Dr. David R. Smith of Duke University, which I mention here for this interesting observation:

While it would be great if we could make things vanish entirely, a cloak needn’t accomplish complete invisibility to be potentially useful. Remember how easy it is to defeat the invisible man? Being invisible is only of fleeting value at best if your adversary knows that you are there. The advantage of invisibility comes about when your adversary has no idea that you’re there. That is, invisibility is probably best thought of as being a really good form of camouflage: it doesn’t have to be perfect to work.

I might add that only recently in motion pictures has it looked even close to perfect, but even in the James Whale days it was seriously convincing.
