Mary Everest Boole (1832-1916) was born Mary Everest in England and spent her early years in France. She married mathematician George Boole. She was the author of several works on teaching and teaching mathematics in particular. This short book, Philosophy and Fun of Algebra, is meant to be read by children and introduces algebra and logic. She uses the word “algebra” broadly, defining it as a “method of solving problems by honest confession of one’s ignorance”. Using this definition, Boole introduces, in a conversational manner, the concepts of logic and algebra, illustrating these concepts with stories and anecdotes, often from biblical sources...

Roosevelt’s popular book Through the Brazilian Wilderness describes his expedition into the Brazilian jungle in 1913 as a member of the Roosevelt-Rondon Scientific Expedition co-named after its leader, Brazilian explorer Cândido Rondon. The book describes all of the scientific discovery, scenic tropical vistas and exotic flora, fauna and wild life experienced on the expedition. One goal of the expedition was to find the headwaters of the Rio da Duvida, the River of Doubt, and trace it north to the Madeira and thence to the Amazon River...

Here are two stores starring the always unconventional Terrestrial Diplomat, Retief. As a diplomat, Retief does not always follow procedure. Well the truth is that he almost never follows procedure but somehow his wit and strength manage to salvage most situations from the bumbling of his superiors. His sardonic approach to inter galactic negotiations in these two stories is a delight to hear. Despite everything, he manages to save the day and come out on top.

The Outline of Science, Volume 1 was written specifically with the man-on-the-street in mind as the target audience. Covering scientific subjects ranging from astronomy to biology to elementary physics in clear, concise and easily understood prose, this popular science work is largely as relevant today as when first published in 1922. Special emphasis is given to the principles of biological adaptation and evolution, especially how they relate to the rise of the human species from lower orders. Also included are the basics of the (then) fairly new concept of relativity and its impact on emerging scientific theories...

Thomas H. Huxley, an English biologist and essayist, was an advocate of the theory of evolution and a self-proclaimed agnostic. A talented writer, his essays helped to popularize science in the 19th century, and he is credited with the quote, “Try to learn something about everything and everything about something.” In The Advance of Science in the Last Half Century, he presents a summary of the major developments in Physics, Chemistry and Biology during the period 1839-1889 and their impact on society, within the historical context of philosophical thought and scientific inquiry going back to Aristotle...

A cross between guidebook and social commentary, The Spinster Book gives clever and humorous insights on topics such as courting, handling men and women, love letters, marriage and spinsterhood.

The sequel to Plague Ship, Voodoo Planet finds the Solar Queen banned from trade and starting her supposed quiet two-year stint as an interstellar mail carrier. But instead her crew accepts a visit to the safari planet of Khatka, where they find themselves caught in a battle between the forces of reason and the powers of Khatka’s mind-controlling wizard.

Warlord of Kor was originally published in 1963 as half of an Ace Double, selected by legendary editor Donald A. Wollheim. It is an interplanetary adventure, as humans probe the mysteries of the planet Hirlaj and the few remaining aliens who live there. Terry Carr never really shone as a writer, though he did write some remarkably thoughtful stories. However, his talents as an editor and anthologist were important and undeniable, and he brought many good writers and authors into science fiction and fantasy...

The Interesting Narrative of the Life of Olaudah Equiano, written in 1789, is the autobiography of Olaudah Equiano. It discusses his time spent in slavery, serving primarily on galleys, documents his attempts at becoming an independent man through his study of the Bible, and his eventual success in gaining his own freedom and in business thereafter. The book contains an interesting discussion of slavery in West Africa and illustrates how the experience differs from the dehumanising slavery of the Americas...

In Defense of Women is H. L. Mencken’s 1918 book on women and the relationship between the sexes. Some laud the book as progressive while others brand it as reactionary. While Mencken didn’t champion women’s rights, he described women as wiser in many novel and observable ways, while demeaning average men. According to Mencken’s biographer, Fred Hobson: Depending on the position of the reader, he was either a great defender of women’s rights or, as a critic labelled him in 1916, ‘the greatest misogynist since Schopenhauer’,'the country’s high-priest of woman-haters.’

John Wesley Powell was a pioneer American explorer, ethnologist, and geologist in the 19th Century. In 1869 he set out to explore the Colorado and the Grand Canyon. He gathered nine men, four boats and food for ten months and set out from Green River, Wyoming, on May 24. Passing through dangerous rapids, the group passed down the Green River to its confluence with the Colorado River (then also known as the Grand River upriver from the junction), near present-day Moab, Utah. The expedition’s route...

Sailing adventure with storms, icebergs, shipwrecks, treasure, and the reawakening of a pirate frozen in suspended animation for nearly fifty years

Mutual Aid: A Factor of Evolution is a book by Peter Kropotkin on the subject of mutual aid, written while he was living in exile in England. It was first published by William Heinemann in London in October 1902. The individual chapters had originally been published in 1890-96 as a series of essays in the British monthly literary magazine, Nineteenth Century. Written partly in response to Social Darwinism and in particular to Thomas H. Huxley’s Nineteenth Century essay, The Struggle for Existence, Kropotkin’s book drew on his experiences in scientific expeditions in Siberia to illustrate the phenomenon of cooperation...

In this work, Kropotkin points out what he considers to be the fallacies of the economic systems of feudalism and capitalism, and how he believes they create poverty and scarcity while promoting privilege. He goes on to propose a more decentralised economic system based on mutual aid and voluntary cooperation, asserting that the tendencies for this kind of organisation already exist, both in evolution and in human society.

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.

When the Inter-Planetary Corporation's (IPC) crack liner “IPV Arcturus” took off on a routine flight to Mars, it turned out to be the beginning of a unexpected and long voyage. There had been too many reports of errors in ship's flight positions from the Check Stations and brilliant physicist Dr. Percival (“Steve”) Stevens is aboard the Arcturus on a fact-finding mission to find out what's really happening, and hopefully save the honor of the brave pilots of the space-liner Arcturus from the desk-jockeys' in the Check Stations implications of imprecision - the nastiest insult you could cast at a ships pilot...

This is a sequel to The Skylark of Space. The novel concerns Richard Seaton and his allies who have encounters with aliens while fighting DuQuesne and the Fenachrone..

Justus von Liebig (1803-1873) was a German chemist who made major contributions to agricultural and biological chemistry and is known for his discovery of nitrogen as an essential plant nutrient. These letters “were written for the especial purpose of exciting the attention of governments, and an enlightened public, to the necessity of establishing Schools of Chemistry, and of promoting by every means, the study of a science so intimately connected with the arts, pursuits, and social well-being of modern civilised nations.”

This is the official report, published nearly 11 months after the first and only atomic bombings in history (to date), of a group of military physicians and engineers who accompanied the initial contingent of U.S. soldiers into the destroyed cities of Hiroshima and Nagasaki. The report presents a clinical description of the devastation, loss of life and continued suffering of the survivors that resulted from the world’s first and only atomic bombings. The appendix is an eyewitness account, contrasting...

First published in 1885, After London, or Wild England is considered to be one of the earliest instances of post-apocalyptic fiction, describing the effects of an unspecified catastrophe that dramatically changes the face of England and its population. Divided into two parts, the first depicts the fall of civilization, as society reverts to its more primitive roots, while the second part is set years after the apocalyptic event and examines the evident changes in both natural scenery and social structure...

Robert Bloch was a prolific writer in many genres. As a young man he was encouraged by his mentor H. P. Lovecraft, and was a close friend of Stanley G. Weinbaum. Besides hundreds of short stories and novels he wrote a number of television and film scripts including several for the original Star Trek. In 1959 Bloch wrote the novel Psycho which Alfred Hitchcock adapted to film a year later. He received the Hugo Award, the World Fantasy Award, the Bram Stoker Award, and he is a past president of the Mystery Writers of America. Published in Amazing Stories in 1958, This Crowded Earth is a thriller set on an overpopulated Earth of the future.

“Mark Phillips” is, or are, two writers: Randall Garrett and Laurence M. Janifer. Their joint pen-name, derived from their middle names (Philip and Mark), was coined soon after their original meeting, at a science-fiction convention. Both men were drunk at the time, which explains a good deal, and only one has ever sobered up. A matter for constant contention between the collaborators is which one. Originally published as That Sweet Little Old Lady, Brain Twister follows the adventures of FBI agent Kenneth J...

The Book of the Damned was the first published nonfiction work of the author Charles Fort (first edition 1919). Dealing with various types of anomalous phenomena including UFOs, strange falls of both organic and inorganic materials from the sky, odd weather patterns, the possible existence of creatures generally held to be mythological, disappearances of people under strange circumstances, and many other phenomena, the book is historically considered to be the first written in the specific field of anomalistics. –

Arabella Buckley had a great love of nature and wished to impart that love to children. Birds of the Air will encourage children to observe birds in their natural environment and notice the habits of each particular bird they encounter.

Wild Life in Woods and Fields by Arabella B. Buckley is a collection of stories that will encourage children to become little naturalists and explore the majesty of the great outdoors. This is science taught in such a charming, delightful way that children will learn without even realizing it!

In By Pond and River, another of Arabella Buckley’s wonderful science books for children, she explains the habitats of ponds and rivers, exposing children to the animals and plant life that are found there.

In 1877, two gentlemen, Messrs Tonnison and Berreggnog, head into Ireland to spend a week fishing in the village of Kraighten. While there, they discover in the ruins of a very curious house a diary of the man who had once owned it. Its torn pages seem to hint at an evil beyond anything that existed on this side of the curtains of impossibility. This is a classic novel that worked to slowly bridge the gap between the British fantastic and supernatural authors of the later 19th century and modern horror fiction. Classic American horror writer H. P. Lovecraft lists this and other works by Hodgson among his greatest influences.

The Kama Sutra, or Aphorisms on Love, has survived at least 1400 years as a dominant text on sexual relations between men and women. Vatsyayana claimed to have written the Kama Sutra while a religious student, “in contemplation of the Deity” - but references to older works, shrewd disputations by Vatsyayana of those authors' recommendations, and careful cataloging of practices in various of the Indian states indicate much more emphasis on kama, or sensual gratification. Part of the book discusses the 64 arts of love employed by masters of coitus...

The Masters had ruled all space with an unconquerable iron fist. But the Masters were gone. And this new, young race who came now to take their place–could they hope to defeat the ancient Enemy of All?

In contrast to Scott’s South Pole expedition, Amundsen’s expedition benefited from good equipment, appropriate clothing, and a fundamentally different primary task (Amundsen did no surveying on his route south and is known to have taken only two photographs) Amundsen had a better understanding of dogs and their handling, and he used of skis more effectively. He pioneered an entirely new route to the Pole and they returned. In Amundsen’s own words: “Victory awaits him who has everything in order — luck, people call it...

“Doc” E.E. Smith pretty much invented the space opera genre, and Triplanetary is a good and well-known example. Physics, time, and politics never stand in the way of a plot that gallops ahead without letup. Having earned a PhD in chemical engineering, it’s understandable that the heroes of Smith’s story are all scientists. He didn’t want to be constrained by the limits of known science, however, so in his hands the electromagnetic spectrum becomes a raw material to be molded into ever-more amazing and lethal forms, and the speed of light is no bar to traveling through the interstellar void...

Audubon’s life naturally divides itself into three periods: his youth, which was on the whole a gay and happy one, and which lasted till the time of his marriage at the age of twenty-eight; his business career which followed, lasting ten or more years, and consisting mainly in getting rid of the fortune his father had left him; and his career as an ornithologist which, though attended with great hardships and privations, brought him much happiness and, long before the end, substantial pecuniary rewards.

Probably no other American writer has a greater sympathy with, and a keener enjoyment of, country life in all its phases—farming, camping, fishing, walking—than has John Burroughs. His books are redolent of the soil, and have such "freshness and primal sweetness," that we need not be told that the pleasure he gets from his walks and excursions is by no means over when he steps inside his doors again. As he tells us on more than one occasion, he finds he can get much more out of his outdoor experiences by thinking them over, and writing them out afterwards...

What a better way to learn about birds than to read this delightful collection of interesting bird stories! John Burroughs was a nature essayist. These creative, observation- and emotion-driven stories about birds (largely from the Northeastern states), have been gathered together into a single volume from all his various works. Every chapter follows one species of birds, and the chapters have been arranged chronologically according to the time of the bird's arrival during the year. This collection has lovely illustrations of the birds by Louis Agassiz Fuertes, and some stories also have poems to go along with them.

Edward George Earle Lytton Bulwer-Lytton, 1st Baron Lytton (1803-1873) was an English novelist, poet, playright, and politician. Lord Lytton was a florid, popular writer of his day, who coined such phrases as “the great unwashed”, “pursuit of the almighty dollar”, “the pen is mightier than the sword”, and the infamous incipit “It was a dark and stormy night.” Despite his popularity in his heyday, today his name is known as a byword for bad writing. San Jose State University holds...

How to describe this book? In a word – savage. For those regular Le Queux mystery listeners, this book is a step in a different direction by the author. The book starts out like most Le Queux. Our hero, Richard Scarsmere, befriends an individual (Omar) at an English boarding school who turns out to be an African prince from a kingdom called Mo. Omar receives a visit from one of his mother’s trusted advisers. His mother, the Great White Queen, seeks him to return home immediately. Omar convinces Scarsmere to return to Africa with him since there is little opportunity awaiting him in London. What follows is a tale of deceit, treachery, barbarity, and mystery.

How do you tell apart a parrot from a carrot? A plover from a clover? A bay from a jay? Although there are several ways of differentiating, R. W. Wood’s use of pun and rhyme is one of the most entertaining!

AFTER TWO CENTURIES….The sound came swiftly nearer, rising in pitch and swelling in volume. Then it broke through the clouds, tall and black and beautifully deadly — the Gern battle cruiser, come to seek them out and destroy them. Humbolt dropped inside the stockade, exulting. For two hundred years his people had been waiting for the chance to fight the mighty Gern Empire … with bows and arrows against blasters and bombs!

On Architecture is a treatise on architecture written by the Roman architect Vitruvius and dedicated to his patron, the emperor Caesar Augustus as a guide for building projects. The work is one of the most important sources of modern knowledge of Roman building methods as well as the planning and design of structures, both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). He is also the prime source of the famous story of Archimedes and his bath-time discovery.

A great civilization’s fate lay in Dick Barrow’s hands as he led his courageous fellow engineers into a strange and unknown land. None of them knew what lay ahead–what dangers awaited them–or what rewards. But they did not hesitate because the first question asked them had been: “Are you a brave man?”

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.

Set in a future in which humanity’s dream of total equality is fully realized and poverty in terms of material wealth has been eliminated, humanity has straight-jacketed itself into the only social system which could make this possible. Class differentiation is entirely horizontal rather than vertical and no matter what one’s chosen field, all advancement is based solely on seniority rather than ability. What is an intelligent and ambitious man to do when enslaved by a culture that forbids him from utilizing his God-given talents? If he’s a military officer in time of war, he might just decide to switch sides...

When a super-robot named Snookums discovers how to build his own superbombs, it becomes obvious that Earth is by no means the safest place for him to be. And so Dr. Fitzhugh, his designer, and Leda Crannon, a child psychologist acting as Snookums’ nursemaid, agree to set up Operation Brainchild, a plan to transport the robot to a far distant planet. But the space ship becomes the scene of some frightening events--the medical officer is murdered, and Snookums appears to be the culprit…

Randall Garrett had this story first published in Astounding Science Fiction September and October of 1959. His twisted sense of humor and gift for the bizarre situation with believable characters shines here. In the not too distant future, Ken Malone, young but promising FBI agent , is given the most important and difficult assignment of his career: find a spy who is stealing information from the Ultra Top Absolute Secret project to develop a non-rocket space ship at Yucca Flats Labs in Nevada. But this is not a normal spy, this spy laughs at the FBI and all attempts to find him or her because they use an unknown new method to steal the information directly from the minds of the scientists.
