A Dirac returns to Caltech
Dirac’s younger daughter Monica visited Caltech as the guest of the physics department, sixty nine years after her father paid his momentous visit to the institution. Monica attended Graham’s colloquium Paul Dirac: the theorist’s theorist, answered a few questions about her family life and posed for photos with audience members. She was delighted to stay in the Athenaeum’s most lavish rooms, the Einstein suite.
Graham was visiting Caltech mainly to participate in the workshop Grassmanian Geometry of Scattering Amplitudes, a subject that will feature in his next book, on pure mathematics and physics.
