By: H. G. Wells (1866-1946)

The First Men in the Moon by H. G. Wells The First Men in the Moon

Written nearly seven decades before Neil Armstrong's historic “Giant leap for Mankind” this book by one of the most influential sci-fi writers in English is an interesting read. The First Men in the Moon by Herbert George Wells, the English author who is today called the Father of Science Fiction, describes a strange and fantastic voyage. Businessman and budding playwright, John Bedford takes a sabbatical from his work and decides to write a play. He moves to a lonely cottage in Kent where he hopes to come up with a theatrical masterpiece...

The Sleeper Awakes by H. G. Wells The Sleeper Awakes

Originally serialized from 1898 to 1903, Wells later made some crucial changes to the piece to create a flawless dystopian science fiction novel published in 1910 and renamed The Sleeper Awakes. The novel focuses on an Englishman, who falls in a deep sleep lasting two centuries, and sees him wake up in an unrecognizable setting and extremely wealthy. An enthralling tale of dystopian society depicted through a colorful imagination, The Sleeper Awakes concentrates on topics including dystopia, political power, religion, plutocracy, and individual and social awakening...

The Food of the Gods and How it Came to Earth by H. G. Wells The Food of the Gods and How it Came to Earth

Two stuffy English scientists, always looking to further their scientific knowledge, create a substance called Herakleophorbia, which in its fourth incarnation – known as Herakleophorbia IV – has the special ability of making things increase greatly in size. As the scientists begin experimentation on some chicks, the substance is misused by some “country folk” who don’t take it seriously and soon Herakleophorbia IV is running rampant throughout England and then across the globe, creating giant plants and animals that wreak havoc on the land and then the people...

A Story of the Stone Age by H. G. Wells A Story of the Stone Age

This story is of a time beyond the memory of man, before the beginning of history. . .

Anticipations by H. G. Wells Anticipations

Wells considered this book one of his most important, a natural follow-up to such works as his Man of the Year Million and The Time Machine. His goal was to get people to think and act in new ways. The book starts with a look at how humans get along socially and how they carry out their business ventures. It then discusses how these elements influence others, such as politics, the world of work, and education. H. G. tried to make clear how the current social order was disintegrating without preparing another to take its place. He then traced the roots of democracy, which in its present state he saw as unworkable. Instead, he proposed a new republic. He also critiqued modern warfare.

Book cover Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying

By: H. L. Mencken (1880-1956)

Book cover Prejudices, First Series

Mencken sharpens his pen and in a collection of short essays delivers acerbic opinions on issues and persons of the time. Among his targets in this volume are critics, H.G. Wells Thorstein Veblen, Arnold Bennett, William Dean Howells, Irvin S. Cobb. Mencken's critiques are delivered against a background of his own well known ethnic, racial, religious, and sectional prejudices. Not for the faint of heart, Mencken's prickly, yet unapologetic, prose reveals a window into American attitudes at the time they were written and their influences on the larger American culture. - Summary by DrPGould

Book cover Notes On Democracy

American journalist H.L. Mencken’s Notes On Democracy was originally published in 1926, yet is still relevant almost 100 years later. Mencken has proposed some succinct and satirical definitions of democracy, such as, “Democracy is the theory that the common people know what they want, and deserve to get it good and hard.” And, “Democracy is the art and science of running the circus from the monkey house.” One predictable result of democracy, Mencken explains, is that the professional politician, who’s objective is always the job, and not the principle, is in a constant struggle for office and its rewards...

Among great technologic developments of the twentieth century has to be that of laser light with its myriad of applications in industry, communication, medicine and many other fields. As author Hal Hellman says in conclusion in this 1968 publication, “Indeed the most exciting probability of all is that lasers undoubtedly will change our lives in ways we cannot even conceive of now.” And, so has it been, and this treatise gives insight into the early days of the research and development of lasers. This booklet is part of the Understanding the Atom Series from the United States Atomic Energy Commission Division of Technical Information. - Summary by Larry Wilson

Book cover Essays on Work and Culture

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...

Book cover Practical Talks by an Astronomer

The present volume has not been designed as a systematic treatise on astronomy. There are many excellent books of that kind, suitable for serious students as well as the general reader; but they are necessarily somewhat dry and unattractive, because they must aim at completeness. Completeness means detail, and detail means dryness. But the science of astronomy contains subjects that admit of detached treatment; and as many of these are precisely the ones of greatest general interest, it has seemed well to select several, and describe them in language free from technicalities...

Book cover Rip Foster Rides the Gray Planet

"Foster, Lieutenant, R. I. P.," blared the voice horn, and five minutes later Rip Foster was off into space on an assignment more exciting than any he had ever imagined. He could hardly believe his ears. Could a green young Planeteer, just through his training, possibly carry out orders like these? Sunny space, what a trick it would be! From the moment Rip boards the space ship Scorpius there is a thrill a minute. He and his nine daring Planeteers must cope with the merciless hazing of the spacemen commanding the ship, and they must outwit the desperate Connies, who threaten to plunge all of space into war...

Book cover The Misplaced Battleship

"It might seem a little careless to lose track of something as big as a battleship ... but interstellar space is on a different scale of magnitude. But a misplaced battleship—in the wrong hands!—can be most dangerous." The world class con man and thief known as the Stainless Steel Rat (diGriz) has another very big problem to solve and this science fiction novella by the great Harry Harrison will see if he can solve it and perhaps four or five more like it before this fascinating and funny tale is finished. 'Use a thief to catch a thief' sounds great but it sometimes has unexpected results.

Book cover The Repairman

This is a collection of 3 of Harry Harrison marvelous early stories that were published in Galaxy, Analog and Fantastic Universe. The Repairman (1958) is a straight fun SF story of a man getting a job done. It is most typical of his later style in series like the Stainless Steel Rat; Toy Shop (1962), a short piece exploring bureaucratic blindness and one ingenious way around it and The Velvet Glove (1956), my favorite for its writing style, fun perspective, sly social commentary on the scene in 1956 and just plain delightful imagination. And he manages to pack excitement and mystery in at the same time.

Through all our faults and mistakes, we women are aiming at better understanding and co-operation with men, and a better adaptation to one another of conditions and persons. We are having to hammer out for ourselves the right principles of government...

When Albert Einstein published his first paper on relativity theory, it caused a stir in the physicists' community. When more and more evidence was gathered to prove the theory correct, even laymen became interested in it. Since the theory of relativity uses involved higher mathematics, it is considered notoriously difficult to grasp, and at the time it was published, it was claimed that only 12 people in the world were able to fully understand it. One of these was the Dutch physicist Hendrik Lorentz, who wrote the articles collected in this book for a lay audience...

"The Greeks were the most intellectual people of the old world. … The study of Greek literature is therefore a proper element in a liberal education. The Greek language, naturally flexible and rich in poetical words, becomes in the hands of the great writers a medium of unequalled force, clearness, and adaptability, able to express as well the highest aspirations of the poet as the subtlest shades of philosophical argument or the most abstruse technicalities. The books of Greece have passed the critical selection of the ages, and the student, unencumbered by masses of inferior material, can approach the works of acknowledged masters, the true fountain-head of European culture...

In Defense of Women by Henry L. Mencken In Defense of Women

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.’
