Definition

Proper noun * Wolfgang Pauli: An Austrian-born theoretical physicist who made fundamental contributions to quantum mechanics and quantum field theory. He is most famous for formulating the Pauli exclusion principle, a quantum mechanical principle that explains the structure of the electron shells in atoms and the organization of the periodic table of elements.

Examples of Usage

• Proper noun:
  • The Pauli exclusion principle, proposed by Wolfgang Pauli, is a cornerstone of quantum physics.
  • In 1945, Wolfgang Pauli received the Nobel Prize in Physics for his discovery of the exclusion principle.
  • The correspondence between Wolfgang Pauli and Carl Jung has been studied by historians of science.

Advanced Usage

• "Pauli effect": A humorous term in scientific folklore referring to the supposed tendency of technical equipment to malfunction spontaneously in the presence of the physicist Wolfgang Pauli. This is not a scientific principle but an anecdotal legend.
  • The laboratory joked about the Pauli effect when the apparatus failed just as they were discussing his work.

Variants and Related Words

• Pauli exclusion principle (noun phrase): The quantum mechanical principle, formulated by Wolfgang Pauli, which states that no two identical fermions (e.g., electrons) can occupy the same quantum state simultaneously within a quantum system.
  • The chemical properties of elements are dictated by the Pauli exclusion principle.
• Pauli matrices (noun phrase): A set of three 2x2 complex matrices which are Hermitian and unitary. They are fundamental in the mathematical description of the spin of spin-½ particles in quantum mechanics.
  • The electron's spin operator is expressed using the Pauli matrices.

Synonyms

• Theoretical physicist: (a general category to which Pauli belonged).

Noun

1. United States physicist (born in Austria) who proposed the exclusion principle (thus providing a theoretical basis for the periodic table) (1900-1958)
