“The only fire for the whole house was the kitchen stove, with a fire box about eighteen inches long and eight inches wide and deep,- scant space for three or four small sticks, around which in hard zero weather all the family of ten shivered, and beneath which in the morning we found our socks and coarse, soggy boots frozen solid.” Thus, with perceptive eye for detail, the American naturalist, John Muir, describes life on a pioneer Wisconsin farm in the 1850’s. Muir was only eleven years old when his father uprooted the family from a relatively comfortable life in Dunbar, Scotland, to settle in the backwoods of North America...

In 1879 John Muir went to Alaska for the first time. Its stupendous living glaciers aroused his unbounded interest, for they enabled him to verify his theories of glacial action. Again and again he returned to this continental laboratory of landscapes. The greatest of the tide-water glaciers appropriately commemorates his name. Upon this book of Alaska travels, all but finished before his unforeseen departure, John Muir expended the last months of his life.

In the book's preface, the author writes: "Let anyone stop to consider how he individually would be affected if all electrical service were suddenly to cease, and he cannot fail to appreciate the claims of electricity to attentive study."In these days when we take for granted all kinds of technology - communications, entertainment, medical, military, industrial and domestic - it is interesting to learn what progress had been made in the fields of electricity and technology by the beginning of the 20th century...

The seven follies of science; a popular account of the most famous scientific impossibilities and the attempts which have been made to solve them to which is added a small budget of interesting paradoxes, illusions, and marvels.

The Subjection of Women is the title of an essay written by John Stuart Mill in 1869, possibly jointly with his wife Harriet Taylor Mill, stating an argument in favor of equality between the sexes. It offers both detailed argumentation and passionate eloquence in opposition to the social and legal inequalities commonly imposed upon women by a patriarchal culture. Just as in “On Liberty,” Mill defends the emancipation of women on utilitarian grounds, convinced that the moral and intellectual advancement of women would result in greater happiness for everybody.

Part 1 lays out the framework for Positivism as originated in France by Auguste Comte in his Cours de Philosophie Positive. Mill examines the tenets of Comte's movement and alerts us to defects. Part 2 concerns all Comte's writings except the Cours de Philosophie Positive. During Comte's later years he gave up reading newspapers and periodicals to keep his mind pure for higher study. He also became enamored of a certain woman who changed his view of life. Comte turned his philosophy into a religion, with morality the supreme guide. Mill finds that Comte learned to despise science and the intellect, instead substituting his frantic need for the regulation of change.

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...

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...

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.
