Computers make our lives easier in so many ways - they help us do our work, get directions, check the weather, exercise, shop and understand what's happening around the world. But who created them, and why? How have they transformed the way we interact with our surroundings and each other? Packed with accessible information, fun facts and discussion starters, this charmingly illustrated book takes you from the ancient world to the modern day, focusing on important inventions from the earliest known counting systems (such as the Incan quipu) to the sophisticated algorithms behind AI, space travel and wearable tech.
