Send electron through one slit, it acts like a particle. Send electron through two slits, it acts like a wave. Place observer at slits to see which one electron goes through, and then electon acts like a part-icle the act of observing the electron to see which slit it goes through, causes it to go through one of the slits The wrong assumption, of a separate observer that can gain full knowledge of something separate from itself, creates a condition whereby full knowledge is unattainable.
