5/7x+6/7y=-2


y=-3



x=-3



y+2=0




x-3y=0




4y=3x






3y=-4/3x

in this experiment it shows how an atom can show both characteristics of both a wave and a particle, why is it a big deal when they place a detector next to one of the slits and it calapses the wave function to a particle, i know how its weird when it does that but they are saying stuff like its the conscience mind controling the function of the atom, dont they know that when you try to detect or observe something it causes interferance with the wave, can somebody please explain why they are thinking its the conscience mind and not the detector that is causing it to turn into a particle
