    Neils Bohr.

    but the word "planetary" is sketchy. what Bohr claimed was that atomic orbitals are quantized, and transitions between the different orbitals could only occur via the absorption or emission of light of *very* specific wavelengths.

    but an atom is not a classical object. heisenberg's uncertainties still plays their part. electrons do not circle the nucleus like planets circle the sun

    they can be found at average radii that equal bohr's values. but they are only *exactly* there if their momenta is completely unknown. in practical terms. that means that the "expectation values" of the orbital radii are quote "equal" to bohr's radii, but at any point, the electron need not be exactly there.

    cheers
