Revoked Invitations to Physics Conference

Times Higher Education details a physics conference where it's not enough to be invited; you also have to be sure your invitation isn't revoked. According to the account, one of those rejected shared the 1973 Nobel Prize in Physics. Brian Josephson, head of the Mind-Matter Unification Project at Cambridge, was rejected because "one of his principal research interests is the paranormal." Two other invitations were also withdrawn.
