« Shortly before his death Pauli was handed the paper of a young American physicist whom his colleagues suspected of being a budding genius. After studying it carefully, Pauli, rocking sadly, gave it back with the acid comment: 'It is not even wrong', meaning that there was not a spark of imagination in it »

"Not even wrong" is a phrase often used to describe pseudoscience or bad science. It describes an argument or explanation that purports to be scientific but uses faulty reasoning or speculative premises, which can be neither affirmed nor denied and thus cannot be discussed rigorously and scientifically.

In 1925, Wolfgang Pauli introduced two new numbers and formulated the Pauli principle, which proposed that no two electrons in an atom could have identical sets of quantum numbers.
