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...

An Introduction to Metaphysics (Introduction a la Metaphysique) is a 1903 essay by Henri Bergson that explores the concept of reality. For Bergson, reality occurs not in a series of discrete states but as a process similar to that described by the Greek philosopher Heraclitus. Reality is fluid and cannot be completely understood through reductionistic analysis, which he said “implies that we go around an object”, gaining knowledge from various perspectives which are relative. Instead, reality can be grasped absolutely only through intuition, which Bergson expressed as “entering into” the object.

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...

History made interesting for young readers—This Country of Ours by Henrietta Elizabeth Marshall provides a simple and easy to comprehend way of looking at the history of the United States. Arranged chronologically in seven long chapters, it presents events in a story form, making them memorable and very different from other formats. One of the challenges that writers of history face is about fleshing out the characters and making the bland repetition of dates and dynasties seem relevant to modern day readers...

Henry Walton Bibb was born a slave. His father was white although his identity was not positively known. Bibb was separated from his mother at a very young age and hired out to other slave owners for most of his childhood. Always yearning for his freedom, he made his first escape from slavery in 1842. He was recaptured and escaped, recaptured and escaped over and over; but he never gave up on his desire to be a man in control of his own destiny.

The Education of Henry Adams records the struggle of Bostonian Henry Adams (1838-1918), in early old age, to come to terms with the dawning 20th century, so different from the world of his youth. It is also a sharp critique of 19th century educational theory and practice. In 1907, Adams began privately circulating copies of a limited edition printed at his own expense. Commercial publication had to await its author's 1918 death, whereupon it won the 1919 Pulitzer Prize. (Introduction by Wikipedia)

This book is often described as an instruction manual on the subject of rat-catching. It does indeed contain a good deal about rats, ferrets and dogs, but it is much more than that. Barkley fills the book with humour, sharp observation, and his sheer joy of living in the countryside. The framework of the book is indeed a course by fictional rat-catcher Bob Joy, who suggests that rat-catching might be a suitable alternative career for boys at Eton, Harrow and the other major English public schools...

Its purpose … is to tell in simple fashion the story of some Americans who showed that they knew how to live and how to die; who proved their truth by their endeavor; and who joined to the stern and manly qualities which are essential to the well-being of a masterful race the virtues of gentleness, of patriotism, and of lofty adherence to an ideal. It is a good thing for all Americans … to remember the men who have given their lives in war and peace to the service of their fellow-countrymen, and to keep in mind the feats of daring and personal prowess done in time past by some of the many champions of the nation in the various crises of her history.

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...

On August 31, 1846, twenty-nine-year-old Henry David Thoreau left his cabin on Walden Pond to undertake a railroad and steamboat journey to Bangor, Maine, from where he would venture with his Penobscot guide Joe Polis deep into the backwoods of Maine. This account of his expedition, some think, is a profounder exploration of the philosophical themes of the more famous "Walden" than is the latter book, at least revealing his fundamental perspectives in embryonic form. Of particular interest is his sympathetic and penetrating observation of the Indian nations of Maine, especially the Penobscot and Passamaquoddy.

Henry Dawson has written several vignettes of railroad men from the days of steam locomotives. His goal is to show the reader that they are not just rough men, but are also brave and heroic men through descriptions of divers dangers encountered on the tracks.

Henry Ford profiles the events that shaped his personal philosophy, and the challenges he overcame on the road to founding the Ford Motor Company. Throughout his memoir, he stresses the importance of tangible service and physical production over relative value as judged by profits and money. He measures the worth of a business or government by the service it provides to all, not the profits in dollars it accumulates. He also makes the point that only service can provide for human needs, as opposed to laws or rules which can only prohibit specific actions and do not provide for the necessaries of life...

Written in a conversational style that will appeal to the younger person as well as seasoned professional, "Thinking as a Science" is timeless classic. Through eleven chapters, the last being a descriptive, annotated bibliography, Henry Hazlitt systematically takes the step-by-step on the process of introducing logic and context into the thinking process. The rather long chapter on "Reading and Thinking" clarifies several notions on where one needs to understand where mere knowledge acquisition ends and using reading the stimulate thinking begins.For an individual who was largely self taught, Hazlitt's contribution to the process of thinking is a must-read.

A Small Boy and Others is a book of autobiography by Henry James published in 1913. The book covers James’s earliest years and discusses his intellectually active family, his intermittent schooling, and his first trips to Europe.

The Abraham Lincoln Statue at Chicago is accepted as the typical Westerner of the forum, the rostrum, and the tribune, as he stood to be inaugurated under the war-cloud in 1861. But there is another Lincoln as dear to the common people–the Lincoln of happy quotations, the speaker of household words. Instead of the erect, impressive, penetrative platform orator we see a long, gaunt figure, divided between two chairs for comfort, the head bent forward, smiling broadly, the lips curved in laughter, the deep eyes irradiating their caves of wisdom; the story-telling Lincoln, enjoying the enjoyment he gave to others. (from the preface of the book)

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)

Ambassador Morgenthau’s memoirs of his years in the service of the United States in Constantinople, (today Istanbul), are an important primary historical resource for the study of the dissolution of the Ottoman Empire and the Armenian Genocide. During this genocide, approximately 1,500,000 Armenians living in Anatolia were murdered in an attempt to rid Turkey of its non-Turkish populations. Mr. Morgenthau left Turkey a frustrated man, having done all that he was able through diplomatic circles to halt the murders, to no avail...

Henry Ossian Flipper--born into slavery in Thomasville, Georgia on March 21, 1856--did not learn to read and write until just before the end of the Civil War. Once the war had ended, Flipper attended several schools showing a great aptitude for knowledge.

”Why do you choose such a title as The Valley of Vision for your book” said my friend; “do you mean that one can see farther from the valley than from the mountain-top?” This question set me thinking, as every honest question ought to do. Here is the result of my thoughts, which you will take for what it is worth, if you care to read the book. The mountain-top is the place of outlook over the earth and the sea. But it is in the valley of suffering, endurance, and self-sacrifice that the deepest visions of the meaning of life come to us.

Vizetelly, writing under the pseudonym J. Tyrwhitt Brooks, recalls an expedition to California he took between 1847-1848 . Originally, he planned to enlist as a surgeon for the US Army during the Mexican war, but conflicts had ended by the time he applied. In a quick change of plans, he joined a group of prospectors on their way to the newly found gold fields of California. While he might not find service in the military, his training as a physician made him a valuable addition to the ragtag team of explorers...
