Описание: Perfect for history buffs and armchair algebra experts, Unknown Quantity tells the story of the development of abstract mathematical thought. John Derbyshire discovers the story behind the formulae, roots, and radicals. As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from "this plus this equals this" to "this plus what equals this?" gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

Описание: Hetty Howland Green (1834-1916), born Hetty Howland Robinson, and known in her later years as "The Witch of Wall Street", was born in the whaling town of New Bedford, Massachusetts to Quaker parents. This biography charts Hetty Green's extraordinary ascent up the pyramid of wealth to a point where, in the earliest years of the twentieth century, she was being identified as the richest woman in America. The first in a series of brief biographies of significant tycoons, this is an insight into the life and methods of one of the earliest and most influential business women in the US. It examines the source of her wealth, and her method of building upon that. It also profiles those who helped or thwarted her along the way.
