Wolfgang Pauli was born in Vienna in 1900. A true child prodigy, at barely 20 years old, he authored a masterful 200-page article on Einstein's theory of relativity, which astonished Einstein himself. He quickly became one of the pillars of the quantum revolution in the 1920s, alongside Bohr, Heisenberg, and Schrödinger.
Known for his brilliant mind but also for his acerbic character and ruthless intellectual honesty, he was nicknamed the 'conscience of physics'.
In 1930, Pauli underwent a violent crisis. The divorce of his parents, his mother's suicide, and his own disastrous marriage, which lasted only a few months, plunged him into depression and alcoholism. His father, concerned, advised him to consult the psychiatrist Carl Gustav Jung, who lived near Zurich where Pauli worked.
Jung was immediately fascinated by Pauli's dream material. Not wanting to influence the dreams of a scientist of such stature, Jung initially entrusted Pauli to one of his students. Over the following years, Pauli recorded more than 1300 dreams, of extraordinary symbolic richness (often related to alchemy and physics), which Jung used extensively in his own books.
A fundamental principle stating that two fermions (such as electrons) cannot occupy the same quantum state simultaneously. This explains the structure of atoms, chemistry, and the solidity of matter. (Nobel Prize 1945)
In 1930, to save the principle of energy conservation during beta decay, Pauli postulated the existence of a ghostly particle, without mass or charge: the neutrino. Its existence would not be experimentally confirmed until 26 years later.
Pauli was convinced that the exploration of matter (physics) and the exploration of the mind (psychology of the unconscious) both reached a common frontier in the mid-20th century.
He believed that Jungian archetypes were not only the foundations of the human psyche but also the ordering principles of the physical universe. Synchronicity, according to him, was proof that the distinction between observer and object, between inner and outer, was an illusion created by our human consciousness. The ultimate reality is the Unus Mundus.
Beyond theory, Pauli is famous for an amusing and terrifying anomaly: the 'Pauli Effect'. It was notorious among physicists that Pauli's mere presence in a room was enough to cause experimental equipment failures, glass breakages, or short circuits.
A famous example: the explosion of precision equipment in Professor Franck's laboratory at the University of Göttingen. Franck wrote to Pauli in Zurich jokingly stating that at least this time, he was not to blame. Pauli replied that at the exact time of the explosion, his train to Copenhagen had stopped at the Göttingen station.
Pauli took this effect very seriously. He considered it a classic synchronistic phenomenon, where his own repressed psychological tension interacted physically with his material environment in an acausal manner.
