As part of the My World series, Economics is a book designed to provide an easy-to-understand explanation about the complex world of economics that children may often hear about on news whenever the topics of 'inflation' and the 'rising cost of living' are mentioned. This book concisely explains what basic economic ideas and theories are, how economic activity affects our everyday lives and how our societies and the wider world are shaped by its structures and rules. From car boots sales to large global businesses, this book explores how economic theories help to explain not only how we act as earners, savers and consumers, but also how places like schools and hospitals are run.

Migrants is a book designed to provide an easy-to-understand explanation for all the doubts kids might have when they hear about the 'migrant crisis' on the news. Humanity was nomadic for 99% of its existence. Sedentary life, national borders and the creation of identity documents for increasingly stricter population control are comparatively recent phenomena, and paradoxical given that the world is becoming ever more globalized. The recent emergence of populist movements in the West that are focused on closing borders and rejecting others raises serious questions about our sense of fraternity, especially when we could be facing ever larger migration movements due to the climate crisis. This book concisely explains what migration is, its causes and consequences, and the humanistic and legal aspects regarding it in the simplest, most objective ways possible, so that children have all the information they need to understand the world around them. AGES: 8 plus AUTHOR: Sheddad Kaid-Salah Ferron is a science and physics enthusiast with degrees in physics and pharmacy. Since graduation he has been teaching science to children, continuing to study physics, working in the pharmaceutical field and staring at the universe with his telescope. He now writes popular science books. Eduard Altarriba is a graphic designer and illustrator. He runs Alababala, a Barcelona-based independent studio producing games, exhibitions, animation, apps and workbooks for children that are practical and fun.

What is War? is a book designed to offer a simple answer to all the questions kids might ask when hearing about war and conflict. Why do countries or different ideological groups fight? What are the key points between different types of conflict? Is there such a thing as a just war? What are the tools used to wage war, from weapons to propaganda? How can we end wars, and who are the real winners and losers? This book tells the reader through clear explanations punctuated by historical and contemporary examples what war is and how it can be prevented. It is part of a series of books for children designed to provide them with all the information they need to understand the complex world we live in.

It's never too early to start exploring big ideas. This companion volume to 'My First Book of Quantum Physics' introduces complex science to children through bright illustrations and amusing text. Einstein's theory of relativity is one of the cornerstones of modern physics but it requires a total rethink of our notions of time and space. Strange things happen in a relative universe: length and time are not fixed and depend upon your frame of reference. If you move at high speed, time slows down, space contracts and weight increases. So a period of time for someone on Earth that lasts for hundreds of years may only be a couple of hours for someone travelling in a rocket close to the speed of light. It's mind-boggling stuff, but the theory of relativity has a real impact on our world today. A car's GPS navigation system, for example, uses information received from orbiting satellites and is designed to account for the fact that time ticks at a different rate on these satellites than it does on the ground. Without allowing for relativity's effects, after just a day, your whereabouts according to GPS could be up to 5 miles (8km) from your actual location. So to find out more about how our universe works and how space and time are connected, look no further than this fascinating, illustrated guide to relativity.

Creating and harnessing energy is a fundamental part of enabling life to exist and thrive on earth. Energy comes in a vast array of different forms - using our muscles and those of other creatures, enabling us to move, lift etc, creating heat and steam through fire, capturing the power of the wind in a ship's sails or to turn the blades of a wind turbine, harnessing the power of moving water to generate electricity in a hydroelectric power station, applying the forces of magnetism to turn an electric motor, using solar panels to transfer the sun's energy into electricity for our homes - all of these and more are explained in 'Discovering Energy'.

The world of quantum physics is an amazing place, where quantum particles can do weird and wonderful things, acting totally unlike the objects we experience in day-to-day life. How can atoms exist in two places at once? And just how can a cat be dead and alive at the same time? Find out more with this entertaining illustrated guide to the fascinating, mysterious world of quantum physics.
