Happy 100th birthday to the Bohr atom

AB Lagrelius & Westphal, via Wikipedia (Niels Bohr photo); N.A.Sharp, NOAO/NSO/Kitt Peak FTS/AURA/NSF (solar spectrum) Niels Bohr's model of the hydrogen atom—first published ... which required the development of quantum mechanics in the 1920s.Museum to Display Working Model of Atom

THE New York Hall of Science has created what its director believes to be the world's first realistic working model of an atom. The new ''quantum ... viewer does not see the moving screen or any of the projection apparatus, only the image of a hydrogen ...- The electron cloud model is an atom ... we can only describe electron locations in terms of most probable regions with fuzzy boundaries – thus the term ‘cloud’. As mentioned earlier, the electron cloud model is a product of quantum mechanics.
