This shows physicist Stephen Hawking's life as he deals with the ALS that renders him immobile and unable to speak without the use of a computer. Hawking's friends, family, classmates, and peers are interviewed not only about his theories but the man himself.

Dutch graphic artist MC Escher created some of the most famous graphic illusions in 20th century popular culture. He inspired artists, designers and film directors. Yet his most profound impact was on a different field to art entirely – mathematics. Cosmologist Professor Sir Roger Penrose is one of the world’s leading mathematicians. His research into black holes with Stephen Hawking transformed our understanding of the big bang. In this film, coinciding with the first ever major UK retrospective of Escher’s work Professor Penrose now reveals how his own mathematical sketches inspired some of Escher’s best-known masterpieces.
