These are but a few of the extraordinary consequences of Einstein's theory of relativity.

Robert McMahon considers these questions and more, as well as looking at the legacy of the Cold War and its impact on international relations today.

The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal - everything is moved or restrained by four simple laws. This powerful and compact introduction explains what these four laws are and how they work, using accessible language and virtually no mathematics.

Was love invented by European poets in the Middle Ages, or is it part of human nature? Will winning the lottery really make you happy? Is it possible to build robots that have feelings?

Enzymes are the astonishing tiny molecular machines that make life possible. Each one of these small proteins speeds up a single chemical reaction inside a living organism many millionfold. Working together, teams of enzymes carry out all the processes that collectively we recognize as life, from making DNA to digesting food. This Very Short Introduction explains the why and the how of speeding up these reactions - catalysis - before going on to reveal how we have evolved these catalysts of such extraordinary power and exquisite selectivity.

Economics has the capacity to offer us deep insights into some of the most formidable problems of life and offer solutions to them, too. Combining a global approach with examples from everyday life, Partha Dasgupta describes the lives of two children who live very different lives in different parts of the world: the Midwest USA and in Ethiopia. He compares the obstacles facing them and the processes that shape their lives, their families, and their futures. He shows how economics uncovers these processes, finds explanations for them, and how it forms policies and solutions.

Games are everywhere: Drivers maneuvering in heavy traffic are playing a driving game. Bargain hunters bidding on eBay are playing an auctioning game.
