Through collaboration with Wolfgang Pauli and Werner Heisenberg, Jung intuitively sought to establish a parallelism between psychic processes and the physical world by applying emerging theoretical concepts of quantum physics to his analytical psychology. Wolfgang Pauli, a prominent co-founder of quantum physics, first met Jung in 1930, and for the following twenty-six years they corresponded with each other exploring the relationship that they believed existed between analytical psychology and quantum physics. In 1952, Jung and Pauli published their initial findings in a book entitled The Interpretation of Nature and the Psyche.
