well, if you paid attention to the end of dr pizza's video, you'll see that the attempt to actually observe the phenomenon with a device actually changed the behavior of the particles--not what was observed--but the pattern created by the particle flight path changed.

so, yes, the presence of and attempt to observe does have an effect on the behavior of particles. the simple act of observing--or maybe it is simply being present--changes the fundamental behavior.

That's the crazy thing. I don't quite get it either, I suppose it's something fundamental that I'm missing, but I wonder if it's simply an external object being in the area changes the path of particles? that sounds odd, as I'd think you would do this in a vacuum, and people able to observe without physical interference.

does the act of observation--"capturing" photons (does that even make sense?) to form images--somehow distort the field of the electron path such that it alters behavior?

I think the easiest way to visualize it is using an analogy like temperature....you measure temperature with a thermometer, and you've inherently changed the temperature of the system you're measuring, because heat must flow to the thermometer (or from it) in order for it to be measured. This effect is usually so infinitesimally small as to be negligible for most measurements. However, on the scale of a photon, every interaction is meaningful, and therein lies the uncertainty.

That's a very nice analogy, thanks. 😛
