Katharine E. Dopp was well-known as a teacher and writer of children’s textbooks at the turn of the 20th Century. She was among the first educators to encourage the incorporation of physical and practical activity into the elementary school curriculum at a time when such activities were becoming less commonplace in a child’s home environment. The Tree-Dwellers – The Age of Fear is the first in a series of elementary school texts written by Ms. Dopp that focus on the anthropological development of early human groups...

This book takes its origin in a course of lectures on the history and progress of Astronomy arranged for Sir Oliver Lodge in the year 1887. The first part of this book is devoted to the biographies and discoveries of well known astronomers like Copernicus, Brahe, Kepler, Galileo and Newton. In the second part, the biographies take a back seat, while scientific discoveries are discussed more extensively, like the discovery of Asteroids and Neptune, a treatise on the tides and others.

The author investigates the world of work against a backdrop of culture. Each of the 25 essays focuses on one aspect of the topic. For example, the first essay, "Tool or Man?" looks at two views of man. One is that of strength as the provider of security. The other is that of aesthete, as an enthusiast of the arts or academics or religion. In our culture, provider of security is the winner every time. Man as a source of multiple talents cannot be allowed. As the author frames the argument, "Specialisation has been carried so far that it has become an organised tyranny...

This is Engels' first book (since considered a classic account of England's working class in the industrial age), which argues that workers paid a heavy price for the industrial revolution that swept the country. Engels wrote the piece while staying in Manchester from 1842 to 1844, based on th bohis observations and several contemporary reports conducted over the period.

The Monadology (La Monadologie, 1714) is one of Gottfried Leibniz’s best known works representing his later philosophy. It is a short text which sketches in some 90 paragraphs a metaphysics of simple substances, or monads. What he proposed can be seen as a modification of occasionalism developed by latter-day Cartesians. Leibniz surmised that there are indefinitely many substances individually ‘programmed’ to act in a predetermined way, each program being coordinated with all the others. This is the pre-established harmony which solved the mind body problem at the cost of declaring any interaction between substances a mere appearance, something which Leibniz accepted...

The star Mira was unpredictably variable. Sometimes it was blazing, brilliant and hot. Other times it was oddly dim, cool, shedding little warmth on its many planets. Gresth Gkae, leader of the Mirans, was seeking a better star, one to which his "people" could migrate. That star had to be steady, reliable, with a good planetary system. And in his astronomical searching, he found Sol.With hundreds of ships, each larger than whole Terrestrial spaceports, and traveling faster than the speed of light, the Mirans set out to move in to Solar regions and take over...

A sky pirate armed with superior weapons of his own invention... First contact with an alien race dangerous enough to threaten the safety of two planets... The arrival of an unseen dark sun whose attendant marauders aimed at the very end of civilization in this Solar System. These were the three challenges that tested the skill and minds of the brilliant team of scientist-astronauts Arcot, Wade, and Morey. Their initial adventures are a classic of science-fiction which first brought the name of their author, John W. Campbell, into prominence as a master of the inventive imagination.

As Earth's faster-than-light spaceship hung in the void between galaxies, Arcot, Wade, Morey and Fuller could see below them, like a vast shining horizon, the mass of stars that formed their own island universe. Morey worked a moment with his slide rule, then said, "We made good time! Twenty-nine light years in ten seconds! Yet you had it on at only half power...." Arcot pushed the control lever all the way to full power. The ship filled with the strain of flowing energy, and sparks snapped in the air of the control room as they raced at an inconceivable speed through the darkness of intergalactic space...

The famous scientific trio of Arcot, Wade and Morey, challenged by the most ruthless aliens in all the universes, blasted off on an intergalactic search for defenses against the invaders of Earth and all her allies. World after world was visited, secret after secret unleashed, and turned to mighty weapons of intense force--and still the Thessian enemy seemed to grow in power and ferocity. Mighty battles between huge space armadas were but skirmishes in the galactic war, as the invincible aliens savagely advanced and the Earth team hurled bolt after bolt of pure ravening energy--until it appeared that the universe itself might end in one final flare of furious torrential power....

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...

The Chemical History of a Candle is a series of 6 lectures on chemistry presented to a juvenile audience in 1848. Taught by Michael Faraday - a chemist and physist, and regarded as the best experimentalist in the history of science - it is probably the most famous of the Christmas Lectures of the Royal Society. Taking the everyday burning of a candle as a starting point, Faraday spans the arc from combustion and its products, via the components of water and air (oxygen, hydrogen, nitrogen, carbon), back to the type of combustion that happens in the human body when we breathe...

The Story of the Pony Express offers an in depth account behind the need for a mail route to connect the eastern U.S. with the rapidly populating west coast following the gold rush of California, the springing up of lumber camps, and all incidental needs arising from the settling of the western frontier. Here we learn of the inception of the Pony Express, its formation, successes, failures, facts, statistics, combined with many anecdotes and names of the people who were an integral part of this incredible entity which lasted but less than two years, yet was instrumental in the successful settlement of two thirds of the land mass comprising the expanding country...

Allan Pinkerton (1819-1884), a Scotsman by birth and a barrel-maker by trade, settled in Chicago in its infancy and founded the Pinkertons, the world's first detective agency. Though events associated with the agency after his death have tarnished the name, Pinkerton himself was one of the original human rights advocates. He was a dear friend to John Brown, an advisor to Abraham Lincoln, and 80 years ahead of his time in hiring female detectives. He was also stubborn, irascible, and an egomaniac...

Robert Sterling Yard (February 1, 1861 – May 17, 1945) was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916...

“Mr. Benson sees the world, four or five generations hence, free at last from all minor quarrels, and ranged against itself in two camps, Humanitarianism for those who believe in no divinity but that of man, Catholicism for those who believe in no divinity but that of God.” This apocalyptic novel from the early 1900's is sometimes deemed one of the first modern dystopias.

Thoroughly appalled and sickened by the rising numbers of white-on-black murders in the South since the beginning of Reconstruction, and by the unwillingness of local, state and federal governments to prosecute those who were responsible, Ida Bell Wells-Barnett wrote Southern Horrors, a pamphlet in which she exposed the horrible reality of lynchings to the rest of the nation and to the world. Wells explained, through case study, how the federal government's failure to intervene allowed Southern states...

A fascinating look back at the state of the art of chemistry 100 years ago, this book by James C. Philip, PhD, an assistant professor of chemistry at The Imperial College of Science and Technology, Kensington, provides a "description in non-technical language of the diverse and wonderful way which chemical forces are at work, and their manifold application in modern life" in 1910. Professor Philip relates many of the key chemical discoveries of early academic researchers in the context of the practical uses to which these discoveries were applied in the early 20th century.

This is a textbook on the science of blood and bloodwork by (1908) Nobel Prize winner, Dr. Paul Ehrlich. Should appeal to hematologists, phlebotomists, and just plain folks interested in how our bodies work.

Marie Curie, born in Warsaw in 1867, was a French physicist and chemist famous for her work on radioactivity. She was a pioneer in the field of radioactivity and the first person honored with two Nobel Prizes - in physics (1903) and chemistry (1911). The risks of working with strongly radioactive materials were not known at that time, and she eventually died in 1934 from an illness likely caused by radiation poisoning.Radioactive Substances is the thesis of Marie Curie, presented to the Faculté de Sciences de Paris in 1903, and subsequently published in "Chemical News" vol 88, 1903...

“Society lies under the spell of ancient terrorism and coagulated errors. Science is either wilfully hypocritical or radically misinformed.” John Addington Symonds struck many an heroic note in this courageous (albeit anonymously circulated) essay. He is a worthy Virgil guiding the reader through the Inferno of suffering which emerging medico-legal definitions of the sexually deviant were prepared to inflict on his century and on the one which followed. Symonds pleads for sane human values in...

Talking about viewing the Ocean "If I take the attitude of appreciation, it would be absurd to say that this wave is composed of chemical elements which I do not see; and if I take the attitude of physical explanation, it would be equally absurd to deny that such elements are all of which the wave is made. From the one standpoint, the ocean is really excited; from the other standpoint, the molecules are moving according to the laws of hydrodynamics. If I want to understand the meaning of this scene every reminiscence of physics will lead me astray; if I want to calculate the movement of my boat, physics alone can help me".(from the Introduction)

The People's Common Sense Medical Adviser In Plain English, Or, Medicine Simplified. By R.V. Pierce, M.D. INTRODUCTORY WORDS. Health and disease are physical conditions upon which pleasure and pain, success and failure, depend. Every individual gain increases public gain. Upon the health of its people is based the prosperity of a nation; by it every value is increased, every joy enhanced. Life is incomplete without the enjoyment of healthy organs and faculties, for these give rise to the delightful sensations of existence...

Clarence Darrow was an American lawyer. He remains notable for his wit and agnosticism, which marked him as one of the most famous American lawyers and civil libertarians.In this book, Darrow expands on his lifelong contention that psychological, physical, and environmental influences—not a conscious choice between right and wrong—control human behavior. To my ears (the reader's), the author has a rather simplistic behaviourist view of human behaviour, but he argues his position with wonderful clarity...

In this volume, Orison Swett Marden explains the road to success in simple terms for the benefit of anyone, who wishes to follow in his footsteps. Over 100 years after publication, most of these lessons are still valid today.

Gregor Mendel (1822 - 1884) was an Augustinian monk in the St. Thomas monastery in Brno. His seminal paper "Experiments on Plant Hybridization" presents his results of studying genetic traits in pea plants. It is the ground breaking work on inheritance, being the first to differentiate between dominant and recessive genetic traits. His work was long ignored and deemed controversial, however, at its rediscovery at the turn to the 20th century, it earned Gregor Mendel the title "father of modern genetics".
