The What on Earth? Wallbook of Science & Engineering tells the complete story of human invention from the dawn of civilisation to the present day and beyond. A beam of brilliant white light contains a timeline that shines into Sir Isaac Newton's prism in c. 1680 before spreading out into a spectrum of colours that represent all the main themes of science & engineering, from abstract to infinity. More than 1,000 pictures and captions tell the story of Maths, Measurement, Physics, Chemistry, Medicine, Biology, Earth, Land, Building, Invention, Transport, Communication, Sky and Space. A3 in format and opening into a 2.3 metre long, fully illustrated timeline, The What on Earth? Wallbook of Science & Engineering is perfect for all ages and can be read like a book or unfolded and stuck on the wall. On the reverse side a second narrative identifies 18 of the most amazing moments in the history of science, from Greek engineering genius Archimedes leaping out of the bath shouting Eureka to the rise of the World Wide Web. Presented in easy-to-read news stories, the text provides a brief snapshot of the extraordinary achievements, discoveries and insights scientists and engineers have made through the ages, leading to the modern world as we know it today. A crossword at the end with all the correct answers to be found somewhere on the timeline overleaf provides another way of exploring these incredible stories. This Wallbook has been developed in collaboration with experts at The Science Museum, The Institution of Mechanical Engineers and The Association for Science Education.
