The Science Of Philip Pullman's His Dark Materials

Philip Pullman's 'His Dark Materials' trilogy is an extraordinary work of the imagination. But behind the enthralling fictional worlds of Lyra and Will lies a world of astonishing scientific truth.

The Northern Lights, Will's subtle knife, Mary Malone's amber spyglass, the parallel universes through which Will and Lyra travel, the mulefa and the seed pods, even the mystery of Dust - all are firmly rooted in science.

Award-winning science writers Mary and John Gribbin reveal how the trilogy is steeped in string theory and spacetime, quantum physics and chaos, symbiosis, entanglement and cold dark matter. Ideas which are as strange and beautiful as Philip Pullman's stories, and all the stranger for being true.
