Modelling atomic behaviour underneath incident electromagnetic radiation employing "virtual oscillators" within the absorption and emission frequencies, as an alternative to the (distinct) evident frequencies in the Bohr orbits, led Max Born, Werner Heisenberg and Kramers to explore distinct mathematical versions. They brought about the development of matrix mechanics, the first http://umtsflatvergleich.de/die-vorteile-der-verwendung-einer-hebebuhne-in-ihrem-trainingsprogramm/
