Publisher's Synopsis
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?
