So the thing is, "observe" here means that you want to look at an electron to see which path it's taking. How do you "observe" it? By hurling a photon at it, at light speed, it smashes into the electron, changing its course, and then back to you.
Once you define what's actually happening, it becomes a lot less mysterious why "observation" changes the results.
I think the point of this exepirement is not to observe an electron to see its path, but the fact of obversion itself. Because without obsevation it takes both paths.
Right, but you have to define what "observation" means when you're talking about things that small.
