“The image of Stephen Hawking … in his motorised wheelchair, with head contorted slightly to one side and hands crossed over to work the controls, caught the public imagination, as a true symbol of the triumph of mind over matter. As with the Delphic oracle of ancient Greece, physical impairment seemed compensated by almost supernatural gifts, which allowed his mind to roam the universe freely, upon occasion enigmatically revealing some of its secrets hidden from ordinary mortal view. Of course, such a romanticised image can represent but a partial truth.” An obituary by Hawking’s Cambridge colleague Roger Penrose.
