Explore the fascinating history of the computer, and the people who made them, in this beautifully illustrated guide for children by bestselling author and illustrator Rachel Ignotofsky. 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. The History of the Computer also profiles a global and diverse range of key players and creators - from An Wang and Margaret Hamilton to Steve Jobs and Tim Berners-Lee - and illuminates their goals, their intentions and the impact of their inventions on our everyday lives. This entertaining and educational journey from the bestselling author of Women in Science will help you understand our most important machines and how we can use them to enhance the way we live. You'll never look at your phone the same way again!.
