What is Gold? And what are its properties? Why is it so valuable? How to get this substance? In this book, a whole world awaits you, where people of different professions every day turn a nondescript gray stone into a shiny gold ingot. You will learn how dangerous the gold rush is, how to find gold if you can't see it, why you need bubbles and electricity in gold mining, what aqua regia is, why some ores are so refractory, and much more. Dredges and giant dump trucks, quarries, underground cities and high-tech laboratories are waiting for you. And also - a few games-experiments!
