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…

Jules Henri Poincaré (1854–1912) was one of France’s greatest mathematicians and theoretical physicists, and a philosopher of science. As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. He was responsible for formulating the Poincaré conjecture, one of the most famous problems in mathematics. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory...

The Reverend Gilbert White was the curate of the village of Selborne, a village in Hampshire, from 1784 to his death in 1793, living most of his life in the village. The book is in the form of a collection of letters to two friends, discussing the natural history of the areas that he knew, and natural history in general. White’s intense curiosity and his love for the world about him flow through his simple, straightforward style, and a gentle sense of humour colours many of his anecdotes.

Late nineteenth-century naturalist William J. Long invites us in to the secret worlds of the woodland animals. Containing Long's own animal observations along with stories related to him by other humans who inhabit the woods, these stories give us an insight into the behavior of wild animals as they go about their lives in their own secret places deep in the forests of eastern North America. Although Long was accused in his day of anthropomorphizing the animals he wrote about, readers who are familiar with any of the animals he writes of will have glimpses of recognition at behaviors they have seen for themselves and explore the deeper meanings these actions have in that animal's life...

The unique merit of this nature student rests in his fascinating style of writing, which invariably interests young and old; for without this element his pioneer work in the realm of nature would now be familiar only to scientists, introducing people everywhere into the wonderland of nature hitherto entirely closed to all. This is another chapter in the shy, wild life of the fields and woods. Little Toohkees, the wood mouse that dies of fright in the author’s hand; the mother otter, Keeonekh,...

How does occultism regard vegetarianism? It regards it very favorably, and that for many reasons. These reasons may be divided into two classes: those which are ordinary and physical, and those which are occult or hidden. Let us see in detail why a vegetarian diet is emphatically the purest and the best.

Do you enjoy birdwatching? Would you like to learn a little more about the early conservations efforts to protect wild birds? In the Preface to The Bird Study Book, Pearson tells us “This book was written for the consideration of that ever-increasing class of Americans who are interested in acquiring a greater familiarity with the habits and activities of wild birds.

Why did everybody step off the ship in this strange valley and promptly drop dead? How could a well-equipped corps of tough spacemen become a field of rotting skeletons in this quiet world of peace and contentment? It was a mystery Peter and Sherri had to solve.

Here are two early stories by the well known SF Author Robert Silverberg. The Happy Unfortunate was published first in Amazing Stories in 1957 and explores the angst caused when the human race reaches into space but at the cost of needing to breed a new species; specialized 'spacers' who can withstand the tremendous rigors of acceleration. The Hunted Heroes was published in Amazing stories a year earlier, in 1956. It is a futuristic story that holds great hope for the resilience of the human race after the war destroys most of the world.

“You may think that Mother Nature, like the famous “old woman who lived in the shoe,” has so many children that she doesn’t know what to do. But you will know better when you become acquainted with her, and learn how strong she is, and how active; how she can really be in fifty places at once, taking care of a sick tree, or a baby flower just born; and, at the same time, building underground palaces, guiding the steps of little travellers setting out on long journeys, and sweeping, dusting, and arranging her great house,–the earth...

Do remember reading a panic-mongering news story a while back about genetically engineered “Frankengrass” “escaping” from the golf course where it had been planted? That news story was foreshadowed decades previously in the form of prophetic fiction wherein a pushy salesman, a cash-strapped scientist, and a clump of crabgrass accidentally merge forces with apocalyptic consequences. A triple-genre combo of science fiction, horror, and satire, Greener Than You Think is a forgotten classic that resonates beautifully with modern times. This is a faithful reading of a 1947 first edition text.
