This year marks 150 years since the publication of Jules Verne's classic science-fiction novel Journey to the Centre of the Earth. Author David Whitehouse was a fan of the original book, but noticed that – perhaps understandably given its age - the science in it was somewhat out-of-date. He has now written a new book with the same title, which travels to the heart of the planet and includes much more detail about what lies below the earth’s surface.
