Everything that surrounds - and we ourselves - are made of molecules, combinations of atoms bonded together in very particular ways. They are constructed from a limited set of elements that can combine in an almost limitless variety of arrangements. And when they do, they take on properties and significance greater than the sum of their parts. This book is all about how individual atoms work together to take on new and bigger roles. It offers a look at just 52 molecules that help make us and the world around us. It explores their impact on our lives and how they keep us engaged with life and living.
