Well, to study a physical object you have to impinge on it with something, like light. For very small objects, the energy of the light quantum will affect the object noticeably, so that its condition after "studying" it will not be what it was before you studied it -- which is what you wanted to know. And it is not possible to reduce the effect of the light indefinitely, because the effects are "quantized" -- they come in discrete steps.

I don't think all the writing on the connections is all that intelligent.
