Researchers in the United States have performed thousands of human radiation experiments to determine the effects of atomic radiation and radioactive contamination on the human body. Most of these tests were performed, funded, or supervised by the United States military, Atomic Energy Commission, or various other U.S. federal government agencies. The experiments included a wide array of studies, involving things like feeding radioactive food to mentally disabled children, deliberately releasing radioactive chemicals over U...

Eminent British botanist Agnes Arber provides an authoritative history of printed Herbals -- books widely used in early modern Europe to catalogue the uses of different kinds of plants. While Herbals often reflected pre-scientific and magical beliefs about the properties of plants, Arber's work reveals that they were also critical to the early development of botany and medicine as empirical sciences. A classic in the history of science. - Summary by Josh Leach

This is an immensely readable book explaining anything to do with air - the atmosphere, wind and clouds, and life. This 1896 explanation has since been overtaken by more specific scientific discoveries, but the general concepts certainly still hold true until today. Any beginner interested in meteorology will find this book a great place to start. - Summary by Carolin

He wrote both juvenile and adult science fiction, as well as nonfiction works about medicine and science. His SF works generally focused on medicine and/or psionics. Psionics refers to the practice, study, or psychic ability of using the mind to induce paranormal phenomena. Examples of this include telepathy, telekinesis, and other workings of the outside world through the psyche.

Sidelights on Relativity contains ETHER AND THE THEORY OF RELATIVITY, an address delivered on May 5th, 1920, in the University of Leyden; and GEOMETRY AND EXPERIENCE, an expanded form of an address to the Prussian Academy of Sciences in Berlin on January 27th, 1921. (Intro from Project Gutenberg)

Dumas's 'Celebrated Crimes' was not written for children. The novelist has spared no language -- has minced no words -- to describe the violent scenes of a violent time.In some instances facts appear distorted out of their true perspective, and in others the author makes unwarranted charges. The careful, mature reader, for whom the books are intended, will recognize, and allow for, this fact.The first volume comprises the annals of the Borgias and the Cenci. The name of the noted and notorious Florentine family has become a synonym for intrigue and violence, and yet the Borgias have not been without stanch defenders in history...

Not a complete history of tea, but a pleasant diversion concerning tea, the pleasures found in its drinking, effects, benefits, cautions, etc. Sprinkled with poetry and excerpts from historical personages and the occasional sermon. - Summary by KevinS

In The Concept of Nature, Alfred North Whitehead discusses the interrelatedness of time, space, and human perception.The idea of objects as ‘occasions of experience’, arguments against body-mind duality and the search for an all-encompassing ‘philosophy of nature’ are examined, with specific reference to contemporary (Einstein, with whose theory of relativity he has some complaints) and ancient (Plato, Aristotle) approaches.

In 1907 Wallace wrote the short book Is Mars Habitable? to criticize the claims made by Percival Lowell that there were Martian canals built by intelligent beings. Wallace did months of research, consulted various experts, and produced his own scientific analysis of the Martian climate and atmospheric conditions. Among other things Wallace pointed out that spectroscopic analysis had shown no signs of water vapor in the Martian atmosphere, that Lowell’s analysis of Mars’ climate was seriously flawed and badly overestimated the surface temperature, and that low atmospheric pressure would make liquid water, let alone a planet girding irrigation system, impossible.

The Chemical Constituents of Piper Methysticum or The Chemical Constituents of the Active Principle of The Ava Root is the text of a Master’s Degree thesis presented in June 1915 by Alice A. Ball.

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...

This recording contains two original documents. 1) Life of James Mars, a Slave Born and Sold in Connecticut, by James Mars . James Mars was born in Connecticut in 1790 and spent the better part of his youth a slave working for various owners—once fleeing to the woods with his family to avoid being relocated to the South. At age twenty-five he became a free man and moved to Hartford, Connecticut, where he became a leader in the local African American community. His memoir is one of the more famous accounts of slave life in early New England...

If it is possible to conquer space, then perhaps it is also possible to conquer time. At least that was the theory American scientists were exploring in an effort to explain the new sources of knowledge the Russians possessed. Perhaps Russian scientists had discovered how to transport themselves back in time in order to learn long-forgotten secrets of the past. That was why young Ross Murdock, above average in intelligence but a belligerently independent nonconformist, found himself on a “hush-hush” government project at a secret base in the Arctic...

Before welfare or rehab, what happened to those unfortunates who lost their way, fell through the cracks, were cast off by society? Men such as Andress Floyd and his wife Lillian stepped up. In 1908, the philanthropists converted a mansion in New Jersey into a refuge for homeless men and during the more than 30 years of its operation, more than 100,000 men stayed there until they were able to get back on their feet. In this volume, Floyd has collected 13 diverse true tales of what brought some of the residents to seek succor and enlightenment at the Self-Mastery Colony. - Summary by Lynne Thompson

Dr. Andrew Wilson FRSE was a Scottish physiologist and zoologist and lecturer in zoology and comparative anatomy at the University of Edinburgh and the Royal College of Surgeons of Edinburgh in the late 19th and early 20th century.

The title of this work sufficiently indicates the nature of its contents. The Usages of Good Society relate not only to good manners and to good breeding, but also to the proper etiquette to be observed on every occasion. Note: The abbreviation viz. is short for the Latin videlicet, which itself is a contraction of the Latin phrase videre licet, meaning "it is permitted to see".

“I have promised to introduce you today to the fairy-land of science — a somewhat bold promise, seeing that most of you probably look upon science as a bundle of dry facts, while fairy-land is all that is beautiful, and full of poetry and imagination. But I thoroughly believe myself, and hope to prove to you, that science is full of beautiful pictures, of real poetry, and of wonder-working fairies…” (From the Introduction to The Fairyland of Science)

As it would be impossible to treat, in the compass of a few hundred pages, all the great engineering feats of modern times without reducing individual accounts to uninteresting brevity, the author has preferred, where selection is possible, to take typical instances of engineering practice, and, by the aid of comparatively detailed descriptions, to place the reader in a position to appreciate them and similar undertakings. - Summary by Adapted from the Preface

This is a volume of exploration into the newest inventions of the turn of the previous century. Journalist Archibald Williams walks the reader through diverse inventions which were changing the world at just that point in time. - Summary by Carolin

In 1910, when this book was published, the advancement of modern mechanism was still moving at a rapid pace. It must have seemed like very day, new inventions were made to make life easier. Most of these are still very much in use today, such as the lawn-mower, automatic milking machines in the dairy industry, fire engines, and escalators. Learn about how these worked in this volume. - Summary by Carolin

Metaphysics is essentially a reconciliation of Plato’s theory of Forms that Aristotle acquired at the Academy in Athens, with the view of the world given by common sense and the observations of the natural sciences. According to Plato, the real nature of things is eternal and unchangeable. However, the world we observe around us is constantly and perpetually changing. Aristotle’s genius was to reconcile these two apparently contradictory views of the world. The result is a synthesis of the naturalism of empirical science, and the mysticism of Plato, that informed the Western intellectual tradition for more than two thousand years...

The Topics is is the fifth of Aristotle's six texts on logic which are collectively known as the Organon ("Instrument"). The Topics constitutes Aristotle's treatise on the art of dialectic—the invention and discovery of arguments in which the propositions rest upon commonly-held opinions or endoxa. Topoi are "places" from which such arguments can be discovered or invented. In his treatise on the Topics, Aristotle does not explicitly define a topos, though it is "at least primarily a strategy for argument not infrequently justified or explained by a principle."

De Sophisticis Elenchis is the sixth of Aristotle's six texts on logic which are collectively known as the Organon ("Instrument"). In De Sophisticis Elenchis Aristotle identifies 13 falacies. Verbal Fallacies are: Accent or Emphasis; Amphibology; Equivocation; Composition; Division and Figure of Speech. Material Fallacies are: Accident; Affirming the Consequent; Converse Accident; Irrelevant Conclusion; Begging the Question; False Cause and Fallacy of Many Questions.

On the Heavens (Greek: Περί ουρανού, Latin: De Caelo or De Caelo et Mundo) is Aristotle's chief cosmological treatise. In it Aristotle argues that the Earth is a sphere by pointing to the evidence of lunar eclipses. Aristotle also provides a detailed explanation of his theory of 'gravity' arguing that things which contain 'earth' fall towards the centre of the Universe because 'earth' is naturally attracted to the centre of the Universe. Aristotle argues that if the planet Earth was moved to the location of the Moon then objects which contain 'earth' would not fall towards the centre of the Earth but rather towards the centre of the Universe...
