But this time the resurrected Dark had new plans, plans which involved dangerous experiments in mutation and psionics.And now the rebels realized they were in double jeopardy....

An account given of the lives of five great naturalists (Hippocrates, Aristotle, Galen, Vesalius and Harvey) will not be found devoid of interest. The work of each one of them marked a definite advance in the science of Biology. There is often among students of anatomy and physiology a tendency to imagine that the facts with which they are now being made familiar have all been established by recent observation and experiment. But even the slight knowledge of the history of Biology, which may be obtained from a perusal of this little book, will show that, so far from such being the case, this branch of science is of venerable antiquity...

The first half of this book describes the devastating earthquake that hit San Francisco in 1906, and the subsequent destruction caused by fire. Various eyewitnesses and victims give their account on the tragedy.

"M. Nordmann has presented Einstein’s principle in words which lift the average reader over many of the difficulties he must encounter in trying to take it in. Remembering Goethe’s maxim that he who would accomplish anything must limit himself, he has not aimed at covering the full field to which Einstein’s teaching is directed. But he succeeds in making many abstruse things intelligible to the layman." - Summary by from the Preface by Viscount Haldane Giving significant credit to Henri...

"While many scientific men now understand our place in the universe, we electrons are anxious that every person should know the very important part which we play in the workaday world. It was for this reason that my fellow-electrons urged me to write my own biography. I am pleased to say that my relationship with the scribe who has put down my story in the following pages has been of the most friendly description. I have allowed him to place what he calls "The Scribe's Note" at the beginning of each chapter, but it will be understood clearly that these are merely convenient embellishments, and that I am responsible for the story of my own experiences." (Introduction adapted from the text)

It is not the author's purpose in the present volume to give any instruction in the practice of photography. There are many works dealing with the practical side of the subject. His object is to tell the romantic story of the discovery of this wonderful art, and the steps by which its range has been extended until it can achieve results which only a few years ago would have been thought impossible. A glance at the list of chapters will show what a wide field photography now covers, and what service it renders to man, both in his everyday life and in his most subtle scientific researches. - Summary by The Author

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.

Clarence Darrow was an American lawyer. He remains notable for his wit and agnosticism, which marked him as one of the most famous American lawyers and civil libertarians.In this book, Darrow expands on his lifelong contention that psychological, physical, and environmental influences—not a conscious choice between right and wrong—control human behavior. To my ears (the reader's), the author has a rather simplistic behaviourist view of human behaviour, but he argues his position with wonderful clarity...

In a future time, the solar system is powered by one energy source, controlled by one huge organisation, which has plans to use this control to dominate the planets. Unknown to them, a couple of maverick scientists accidentally develop a completely new form of energy supply and threaten the corporation's monopoly. Naturally, the corporation can't allow this to happen... A stunning story about the manipulation of pure energy, climaxing in interstellar conflict.

Clifford Simak deals with the implications of time travel in his own unique way in this story. What if a group of guys did it on their own, without any help from government or industry? On a shoestring,so to speak? Would anyone believe them? What would you do if you could go back 150,000 years to a time when mastodons and saber toothed tigers roamed North America? And what happens when they run out of money? All these questions are explored in the usual humorous, wry Simak way in this story.

“The martyrs of Science” gives a brief biography of Galileo, Brahe and Kepler. These three men played a pivotal role in the scientific revolution during the early modern period. This book throws light upon their lives, their scientific achievements, adversities which they faced for their work and how they transformed the lives of the future generations forever. It also provides evidence which establishes that the work carried out by them are original irrespective of the claims by other men who tried in vain to rob them of their honor. The author highlights some of their fallacies which hindered their progress.

Plain speaking is necessary in any discussion of religion, for if the freethinker attacks the religious dogmas with hesitation, the orthodox believer assumes that it is with regret that the freethinker would remove the crutch that supports the orthodox. And all religious beliefs are "crutches" hindering the free locomotive efforts of an advancing humanity. There are no problems related to human progress and happiness in this age which any theology can solve, and which the teachings of freethought cannot do better and without the aid of encumbrances.

The progress of astronomy from age to age has been far from uniform—rather by leaps and bounds: from the earliest epoch when man's planet earth was the center about which the stupendous cosmos wheeled, for whom it was created, and for whose edification it was maintained—down to the modern age whose discoveries have ascertained that even our stellar universe, the vast region of the solar domain, is but one of the thousands of island universes that tenant the inconceivable immensities of space...

The Flying Saucers are Real is a book that investigates numerous encounters between USAF fighters, personnel, and other aircraft, and UFOs between 1947 and 1950. Keyhoe contended that the Air Force was actively investigating these cases of close encounter, with a policy of concealing their existence from the public until 1949. He stated that this policy was then replaced by one of cautious, progressive revelation. Keyhoe further stated that Earth had been visited by extraterrestrials for two centuries, with the frequency of these visits increasing sharply after the first atomic weapon test in 1945...

It was the 34th century and all five of the Federation of Planets around Sol were buzzing with their usual activity when the Raiders appeared. They were indeed Raiders of Universes because they had ravaged many systems before reaching Earth and showed no signs of slowing down in the least. Their weapons were invincible, their greed merciless and their natures completely alien. Indeed 'they' were from another dimension entirely. Eating up entire solar systems and planets, they slowed down just a bit when intelligent life was found on Earth...

A short pamphlet from WWI, a sequel of sorts to "Food Preparedness." It first describes basic nutrition and things to consider when choosing what foods to eat, then lists various foods and their amount of calories, carbohydrates, fats, proteins, water, and "ash". This was written before much was known about fat soluble vitamins or saturated vs. unsaturated fats.

Written when the United States extended only to the Mississippi River, by one of the signers of the Declaration of Independence, this short work explores the physical, social, and mental effects of distilled liquors; the classes of people prone to intoxication by them; suggested drinks to use instead of them; and remedies for intoxication and for their habitual use. He takes a medical view of alcoholism, exploring the physical causes rather than blaming moral failure as the cause. Alcoholic drinks that are not distilled are viewed as wholesome drinks, and opium is suggested for pain as being without bad effects or addictive qualities.
