Questions for Discussion:

Have you seen Escher’s Angels and Demons woodcut? Does this chapter make you more interested in looking at other Escher works? Those interested in this topic may also appreciate that Roger and his father corresponded with Escher in the 1950s—and, in developing the “Penrose tribar” they strongly influenced some of Escher’s other works, such as Ascending and Descending.

Why do you think that black holes need to wait until they are warmer than the cosmic microwave background before they begin to radiate?
