D. Paul Dirac – Liquid helium

Show ExplanationHide Explanation

Explanation

The incorrect pair is Paul Dirac–liquid helium. Kamerlingh Onnes produced liquid helium; Dirac made fundamental contributions to quantum theory. Bardeen jointly developed BCS superconductivity theory with Cooper and Schrieffer, de Broglie proposed matter waves, and Hess discovered cosmic radiation.
