Quick Calculation - 2, or The Handbook for Architects, Sculptors, Artists, and Cartographers

This book will make you... a genius! Or at least a person who understands very complex issues that not everyone can solve.

You will learn how to take plans of small plots of land and draw them in such a way that it is immediately clear how great a particular distance is on the plan. This book will explain how to determine the area of a plot of any shape; how to measure distances that cannot be traversed or are inconvenient to walk, such as the width of a river; how to determine the height of a tree without cutting it down, or the height of a building without climbing onto its roof. Furthermore, the book teaches how to measure the speed of the river's current, the water flowing in it, and so on. 

The book was prepared by the remarkable scientist and popularizer of science Y. I. Perelman. 

For future architects, sculptors, artists, cartographers, and everyone who wants to be smarter than computers.
