- - - - Original View of the Atom
  - - - Why Gold??
        
        It can be flattened to only a few atoms thick
      - Held a Florescent Detector behind it
        
        This lit up when struck with alpha particles
        
        Called Scintillation
        
        Scintillations were seen on the far side of the Gold
        
        This proves that......
        
        Atom is mainly empty space
        
        The nucleus is positively charged
        
        Electrons orbit the Nucleus
- - - - Always Larger
- - - - This is a Quantum Leap
- - - - Parts
