An autobiography of Helen Keller published when the author was still in her early 20's. The narrative reveals how her mind developed and matured until she began her studies at Radcliffe College

The World I Live In by Helen Keller is a collection of essays that poignantly tells of her impressions of the world, through her sense of touch, smell, her imagination and dreams. My hand is to me what your hearing and sight together are to you. In large measure we travel the same highways, read the same books, speak the same language, yet our experiences are different. All my comings and goings turn on the hand as on a pivot. It is the hand that binds me to the world of men and women. The hand is my feeler with which I reach through isolation and darkness and seize every pleasure, every activity that my fingers encounter...

"There may seem to be a disappointing lack of prophesy in a book avowedly dealing with the future; but since I believe the women’s movement to be a seeking for knowledge and good, to show what is reasonable and good in the movement is to show what will persist and triumph. Through all our faults and mistakes, we women are aiming at better understanding and co-operation with men, and a better adaptation to one another of conditions and persons. We are having to hammer out for ourselves the right principles of government...

When Albert Einstein published his first paper on relativity theory, it caused a stir in the physicists' community. When more and more evidence was gathered to prove the theory correct, even laymen became interested in it. Since the theory of relativity uses involved higher mathematics, it is considered notoriously difficult to grasp, and at the time it was published, it was claimed that only 12 people in the world were able to fully understand it. One of these was the Dutch physicist Hendrik Lorentz, who wrote the articles collected in this book for a lay audience...

Jules Henri Poincaré (1854–1912) was one of France’s greatest mathematicians and theoretical physicists, and a philosopher of science. As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. He was responsible for formulating the Poincaré conjecture, one of the most famous problems in mathematics. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory...

Two years, two months and two days! This is what forms the time line of one man's quest for the simple life and a unique social experiment in complete self reliance and independence. Henry David Thoreau published Walden in 1884. Originally drafted as a series of essays describing a most significant episode in his life, it was finally released in book form with each essay taking on the form of a separate chapter. Thoreau's parents were in financial straights, but rich intellectually and culturally...

AMUSEMENTS IN MATHEMATICSby HENRY ERNEST DUDENEYPREFACEIn issuing this volume of my Mathematical Puzzles, of which some have appeared in periodicals and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original...

Early eighteenth century England saw the criminal element bargaining with magistrates and lawyers to be released or receive lenient sentences. Neither party could be trusted and the situation grew worse. Enter famed author Henry Fielding, who had a strong social conscience and served as a magistrate. In addition to this treatise, he began a register of convicted criminals, and recruited six full-time, paid constables - known colloquially as "The Bow Street Runners" and hailed as the forerunners of the modern police force.

"The Greeks were the most intellectual people of the old world. … The study of Greek literature is therefore a proper element in a liberal education. The Greek language, naturally flexible and rich in poetical words, becomes in the hands of the great writers a medium of unequalled force, clearness, and adaptability, able to express as well the highest aspirations of the poet as the subtlest shades of philosophical argument or the most abstruse technicalities. The books of Greece have passed the critical selection of the ages, and the student, unencumbered by masses of inferior material, can approach the works of acknowledged masters, the true fountain-head of European culture...

Cyrus W. Field had a dream: to link the Old World of Britain and Europe to that of the New World of North America by a telegraph cable stretching across the great Atlantic Ocean. It took him thirteen years, a lot of money, and many men and ships and cable to make it happen. He wanted to bring the world together and make it a smaller place; to forge alliances and achieve peace. This is his story. (Introduction by Alex C. Telander)

Subtitled, "A Cyclopaedia of the condition and earnings of those that will work, those that cannot work, and those that will not work." "The history of a people from the lips of the people themselves .. their labour, earnings, trials and sufferings, in their own unvarnished language, and to pourtray the condition of their homes and their families by personal observation of the places ..." "My earnest hope is that the book may serve to give the rich a more intimate knowledge of the sufferings, and the frequent heroism under those sufferings, of the poor ...
