Topic: Walter Heitler


  
  Profile of Walter Heitler   (Site not responding. Last check: 2007-11-02)
Walter Heinrich Heitler was born in Karlsruhe in Germany on 2 nd January 1904.
Heitler's research demonstrated the power of the new mechanics by applying and developing it with great success to a number of diverse areas, including the theory of the chemical bond, radiation theory, cosmic rays and quantum field theory.
Heitler’s connection with Ireland is due to his time at the Dublin Institute for Advanced Study between 1941 and 1949 when he was a leading figure in the international physics community.

 Walter Heitler - Wikipedia, the free encyclopedia
In 1936 Heitler’s classic book ‘Quantum Theory of Radiation’ was published (new editions in 1944 and 1954 and five later reprints, the latest being a Dover reprint in 1984).
This was particularly emphasised by Pascual Jordan in the ‘Laudatio for Walter Heitler’ on the occasion of the award of the Max Planck Medal (see Pascual Jordan ‘Begegnungen’, Stalling Verlag 1971).
A further milestone in the understanding of the π-meson – nucleon interaction is a paper (1946) in which Heitler deduces relations between the scattering cross sections as a consequence of the isospin invariance of the interaction.

 Kostas Gavroglu and Ana Simões : The Americans, the Germans, and the beginnings of quantum chemistry: The ...
Heitler and London found the energy to be 72.3 kcals and the internuclear distance 0.86 Angstroms (compared with the experimental values of 109.4 and 0.74).
Heitler and London applied this constraint not in the form of further assumptions about the forces involved, but as an invocation of the Pauli exclusion principle, leading to a quite amazing metamorphosis of the physical content of the mathematical solutions.
Heitler found physics at Göttingen exciting, especially Born's course in quantum mechanics, which started with the matrix forinulation and then derived "God knows how' Schrödinger's equation." (68) Heitler felt that group theory provided the only solution to the many-body problem, and he outlined his program to London in two long letters.

Heitler, Herzberg Observed that Nitrogen Nuclei Obey Bose
However, Walter Heitler and Gerhard Herzberg were the ones who recognized the difference in intensity alternation of rotational lines from that in H
Heitler and Herzberg therefore concluded that N nuclei obey Bose statistics.

 Arnold Sommerfeld - Wikipedia, the free encyclopedia
However, in the early 20th century, theorists, such as Sommerfeld at Munich and Max Born at the University of Göttingen, with their early training in mathematics turned this around so that mathematical physics, i.e., theoretical physics, became the prime mover and experimental physics was used to verify or advance theory.
After getting their doctorates with Sommerfeld, Wolfgang Pauli, Werner Heisenberg, and Walter Heitler became Born’s assistants and made significant contributions to the development of quantum mechanics, which was then in very rapid development.
Over his 32 years of teaching at Munich, Sommerfeld taught general and specialized courses, as well as holding seminars and colloquia.

More recently, chaos theorist Mitchell Feigenbaum consulted Goethe's work and was surprised to find that "Goethe had actually performed an extraordinary set of experiments in his investigation of colors." Not only that, Feigenbaum persuaded himself that "Goethe had been right about color!"
