Quantum physics, black holes, string theory, the Big Bang, dark matter, dark energy, parallel universes: even if we are interested in these fundamental concepts of our world, their language is the language of maths. Which means that despite our best intentions of finally grasping, say, Einstein's Theory of General Relativity, most of us are quickly brought up short by a snarl of nasty equations or an incomprehensible graph. Christophe Galfard's mission in life is to spread modern scientific ideas to the general public in entertaining ways. Using his considerable skills as a brilliant theoretical physicist and successful young adult author, this book employs the immediacy of simple, direct language to show us, not explain to us, the theories that underpin everything we know about our universe. Employing everyday similes and metaphors, addressing the reader directly, and writing stories rather than equations render these astoundingly complex ideas in an immediate and visceral way. Utterly captivating and entirely unique, The Universe in Your Hand will find its place among other classics in the field. Readers looking to expand their knowledge of physics and cosmology will find everything they need here.” - Publishers Weekly, Starred Review
