The amazing true science behind the fiction of His Dark Materials , ideal for fans of the original trilogy and The Book of Dust, with an introduction by Philip Pullman.

Award-winning science writers Mary and John Gribbin reveal how the world of Pullman's His Dark Materials trilogy ( Northern Lights, The Subtle Knife and The Amber Spyglass ) is rooted in astonishing scientific truth. Drawing on string theory and spacetime, quantum physics and chaos theory, they answer fascinating questions such as: could parallel worlds like Will's and Lyra's really exist? How does the subtle knife cut through anything? Could there be a bomb like the one made with Lyra's hair? And, of course, what are the Dark Materials?
