Carrying out the last wishes of a comrade, mercenary Eric John Stark takes on the task of returning a stolen talisman to a walled city near the Martian pole; a city that guards the mysterious Gates of Death. Now all he has to do is get past the brutal clans of Mekh and the shadowy Lord Ciaran to get to Kushat where they’ll probably attempt to kill him. All while he tries to hold on to a talisman that imprints ancient memories of the Gates in his mind. That’s not easy for a human raised by Mercurian aborigines...

Tom Corbett - Space Cadet was one of the first multimedia sensations. In the 1950s the character had his own radio show, TV series, comic book, breakfast cereal, and a line of young-adult novels. A cross between "Tom Brown's School Days" and Horatio Hornblower (and loosely based upon Robert A. Heinlein's novel "Space Cadet"), the books follow the adventures of Tom and his friends Roger Manning and Astro as they work their way through Space Academy to become officers of the Solar Guard. Along the way they tangle with space pirates, smugglers, and the threat of demerits for breaking the rules...

This book is part of the on-going adventures of Tom Corbett in the Space Cadet Stories. Tom, Astro and Roger are determined to find the saboteurs but get framed in the process, risking court martial and expulsion from the Space Academy. NOTE: Carey Rockwell is a pseudonym used by Grosset & Dunlap. It is unknown who wrote the books.

A science fiction novel that was originally produced in four parts in the publication: Astounding Stories in June, September, November 1932, January 1933. The main character is Dean Rawson, who plans on discovering a way of mining power from a dead volcano, but ends up discovering more than he bargained for.

Published in 1920, Slosson’s Easy Lessons in Einstein is one of the first popularizations of Einstein’s theory of relativity. This book is meant to convey to the general reader the ideas of relativity in non-mathematical terms, by the use of thought experiements and pop-cultural references of the day. This edition also includes a short article by Einstein on Time, Space and Gravitation.

Joseph Lister was born near London in 1827. He studied medicine at the University of London and pursued a career as a surgeon in Scotland. He became professor of Surgery in Glasgow and later (1877) at Kings College Hospital, in London. Lister’s contribution to the advancement of surgery cannot be overestimated. Before his work on antisepsis, wounds were often left open to heal, leading to long recoveries, unsightly scarring, and not infrequently amputation or death due to infection. Lister’s work enabled more wounds to be closed primarily with sutures, drastically reducing healing time, scarring, amputations, and deaths due to infection...

Delightful sketches of British wild birds – a bird for every month of the year from the pheasant in January to the robin in December. This collection of articles, reprinted in book form from the periodical The Outlook, is full of fascinating information about bird behaviour and habitat, as well as many interesting anecdotes. Out of date in some respects, particularly in its reference to the (now illegal) collecting of birds’ eggs, this book brings home forcefully how the populations of some British wild birds have declined since it was written.

An account given of the lives of five great naturalists (Hippocrates, Aristotle, Galen, Vesalius and Harvey) will not be found devoid of interest. The work of each one of them marked a definite advance in the science of Biology. There is often among students of anatomy and physiology a tendency to imagine that the facts with which they are now being made familiar have all been established by recent observation and experiment. But even the slight knowledge of the history of Biology, which may be obtained from a perusal of this little book, will show that, so far from such being the case, this branch of science is of venerable antiquity...

Jane Addams was the first American woman to be awarded the Nobel Peace Prize. In a long, complex career, she was a pioneer settlement worker and founder of Hull-House in Chicago, public philosopher (the first American woman in that role), author, and leader in woman suffrage and world peace. She was the most prominent woman of the Progressive Era and helped turn the nation to issues of concern to mothers, such as the needs of children, public health and world peace. She emphasized that women have a special responsibility to clean up their communities and make them better places to live, arguing they needed the vote to be effective...

Doubleday chronicles the history of everyday inventions that form the foundation of technology now common through the world. While some of the inventions are no longer used, each example shows how inventors contributed to technology through perseverance, inspiration and clever observations. In each chapter, he gives a clear, understandable background of the technology.Many of the now outdated inventions may have inspired later inventions by meeting emerging demands. For example, Edison's filament bulb is now being phased out by more efficient CFL's, but Edison's contribution to indoor lighting likewise removed the need for inefficient gas-burning lamps...

Elisha Gray (August 2, 1835 – January 21, 1901) was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois and is considered by some writers to be the true inventor of the variable resistance telephone, despite losing out to Alexander Graham Bell for the telephone patent.

MANUAL OF SURGERY, OXFORD MEDICAL PUBLICATIONSBY ALEXIS THOMSON, F.R.C.S.Ed.PREFACE TO SIXTH EDITION Much has happened since this Manual was last revised, and many surgical lessons have been learned in the hard school of war. Some may yet have to be unlearned, and others have but little bearing on the problems presented to the civilian surgeon. Save in its broadest principles, the surgery of warfare is a thing apart from the general surgery of civil life, and the exhaustive literature now available on every aspect of it makes it unnecessary that it should receive detailed consideration in a manual for students...

The Woods Hutchinson Health Series, A HANDBOOK OF HEALTHBy Woods Hutchinson, A. M., M. D. PREFACE Looking upon the human body from the physical point of view as the most perfect, most ingeniously economical, and most beautiful of living machines, the author has attempted to write a little handbook of practical instruction for the running of it. And seeing that, like other machines, it derives the whole of its energy from its fuel, the subject of foods--their properties, uses, and methods of preparation--has been gone into with unusual care...

The Child's Day, The Woods Hutchinson Health SeriesBy Woods Hutchinson, A.M., M.D. FOREWORD If youth only knew, if old age only could! lamented the philosopher. What is the use, say some, of putting ideas about disease into children's heads and making them fussy about their health and anxious before their time? Precisely because ideas about disease are far less hurtful than disease itself, and because the period for richest returns from sensible living is childhood--and the earlier the better. It is abundantly worth while to teach a child how to protect his health and build up his strength; too many of us only begin to take thought of our health when it is too late to do us much good...

Capt. Robert F. Scott's bid to be the leader of the first expedition to reach the South Pole is one of the most famous journeys of all time. What started as a scientific expedition turned out to be an unwilling race against a team lead by R. Admunsen to reach the Pole. The Norwegian flag already stood at the end of the trail when Scott's party reached their target. All the five men of the Scott expedition who took part in the last march to the Pole perished on their way back to safety. Robert F. Scott kept a journal throughout the journey, all the way to the tragic end, documenting all aspects of the expedition...

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.
