Single slit Definition and 156 Threads

Reading the derivation for the single slit diffraction minima formula from this site, I'm not convinced about its argument. http://www.math.ubc.ca/~cass/courses/m309-03a/m309-projects/krzak/index.html" What I'm having trouble understanding is the explanation of the formula for minima when m>1...

Basically I am wondering if the act of detecting the path which the electron didn't go affects the interference pattern. But I'll be more specific. So we have the double slit experiment with electrons, they have a 50/50 chance of going through each slit, and if we have this setup we will...
