On Architecture is a treatise on architecture written by the Roman architect Vitruvius and dedicated to his patron, the emperor Caesar Augustus as a guide for building projects. The work is one of the most important sources of modern knowledge of Roman building methods as well as the planning and design of structures, both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). He is also the prime source of the famous story of Archimedes and his bath-time discovery.

At one time Race Cargill had been the best Terran Intelligence agent on the complex and mysterious planet of Wolf. He had repeatedly imperiled his life amongst the half-human and non-human creatures of the sullen world. And he had repeatedly accomplished the fantastic missions until his name was emblazoned with glory. But that had all seemingly ended. For six long years he’d sat behind a boring desk inside the fenced-in Terran Headquarters, cut off there ever since he and a rival had scarred and ripped each other in blood-feud...

“Mark Phillips” is, or are, two writers: Randall Garrett and Laurence M. Janifer. Their joint pen-name, derived from their middle names (Philip and Mark), was coined soon after their original meeting, at a science-fiction convention. Both men were drunk at the time, which explains a good deal, and only one has ever sobered up. A matter for constant contention between the collaborators is which one. Originally published as That Sweet Little Old Lady, Brain Twister follows the adventures of FBI agent Kenneth J...

Mary Everest Boole (1832-1916) was born Mary Everest in England and spent her early years in France. She married mathematician George Boole. She was the author of several works on teaching and teaching mathematics in particular. This short book, Philosophy and Fun of Algebra, is meant to be read by children and introduces algebra and logic.

"In this little book I have sought, in a series of stories or sketches, to present only the first steps in human progress. Man has risen from a stage of lowest savagery, little higher than the apes, buffeted by the hand of Nature, dependent upon the wild game he might kill or the food he found ready to hand, a fearing and a furtive creature of the forests and of the plains, preyed upon by a thousand stronger foes, to a being able to provide warmth and clothing and shelter against the rains and the cold and food against the seasons...

Regarded as the one of the earliest examples of feminist philosophy, A Vindication of the Rights of Woman is written as a direct response to Charles Maurice de Talleyrand-Périgord, a French politician who delivered a report to the French National Assembly suggesting that women should only receive domestic education and additionally encourages women to stay clear of political affairs. In her treatise, Wollstonecraft avidly criticizes this inadequate perception of women as an inferior sex and attacks social inequality, while also arguing for women’s rights in the hope of redefining their position both in society and in marriage...

Wollstonecraft's A Vindication of the Rights of Men attacks aristocracy and advocates republicanism. It was published in response to Edmund Burke's Reflections on the Revolution in France , which was a defence of constitutional monarchy, aristocracy, and the Church of England, and an attack on Wollstonecraft's friend, the Rev Richard Price. Hers was the first response in a pamphlet war that subsequently became known as the Revolution Controversy, in which Thomas Paine's Rights of Man became the rallying cry for reformers and radicals...
