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...

George Muller was a great hero of faith. His greatest aim was to demonstrate that God answers prayer and can be trusted for every minute detail of life. Spending countless hours asking God to provide his needs, he only relied upon God. God called him to care for orphans and he conducted his orphanage in the same way, on faith alone. When a certain need was apparent, they would immediately go to God in prayer. In this dynamic dependance on God, He always proved faithful. He also established over a hundred schools, educating over a hundred thousand people! His example of absolute dependence on God stands in the gap of history to declare that God is enough, and He is faithful!

This post-apocalyptic novella tells the story of the downfall of civilisation and mankind following a solar cataclysm in the late 20th century. To survive, the remnants of humanity had to build a new civilization underground in the complete absence of all species except mankind, choosing to base it only on love and beauty, the fine arts and intellectual pursuits. In view of the sun's current inactivity, this frighteningly prophetic tale might have been written today, saving that the cultural references and the fluid prose might be beyond, if one dares say so, many modern writers...

The adventures of an Indian boy and his beloved elephant. Born near Calcutta, Mukerji won the Newbury Medal for children's fiction.

"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)

The Woodpeckers is a wonderful introduction to the world of bird study for the young naturalist, covering such topics as how he finds food, courting, how he builds his nest, the interesting ways he uses his different body parts as tools, among other topics discussed in the book. If you wish to investigate further, the book has a few diagrams and an Appendix that contains more technical information such as detailed descriptions of the different species of North American woodpeckers which were not read as part of this audiobook.

Joseph Priestley, FRS (13 March 1733 (O.S.) – 6 February 1804) was an 18th-century English theologian, Dissenting clergyman, natural philosopher, chemist, educator, and political theorist who published over 150 works. In “Experiments and Observations on Different Kinds of Air,” he reviews experiments with gases. A common theme in this work is measuring the volumes of gases held in glass tubes, and their increase or decrease when exposed to other substances. He also tests the effects of gases on mice, plants and insects...

This paper takes the reader through the early settlement from 1783 to the modern period of 1888-1912. We see how farming and farm industries developed and how the population was distributed during these times. We see the trends of settlers moving into the Urban centers instead of rural and how the farm industries (making cheese, butter, wool, etc) move off the farm to the city factories. Excerpt: “The farmer’s wife in those days was perhaps the most expert master of trades ever known. She could spin and weave, make a carpet or a rug, dye yarns and clothes, and make a straw hat or a birch broom...

Professor Freud developed his system of psychoanalysis while studying the so-called borderline cases of mental diseases, such as hysteria and compulsion neurosis. By discarding the old methods of treatment and strictly applying himself to a study of the patient's life he discovered that the hitherto puzzling symptoms had a definite meaning, and that there was nothing arbitrary in any morbid manifestation. Psychoanalysis always showed that they referred to some definite problem or conflict of the person concerned...

Metaphysics is essentially a reconciliation of Plato’s theory of Forms that Aristotle acquired at the Academy in Athens, with the view of the world given by common sense and the observations of the natural sciences. According to Plato, the real nature of things is eternal and unchangeable. However, the world we observe around us is constantly and perpetually changing. Aristotle’s genius was to reconcile these two apparently contradictory views of the world. The result is a synthesis of the naturalism of empirical science, and the mysticism of Plato, that informed the Western intellectual tradition for more than two thousand years...

"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.

The Galactic Empire is slowly 'welcoming' into the family of civilized worlds those systems so far off in the backwater of the galaxy that they have been overlooked and ignored for the past 500 years or so. This is purely routine work because every planet offered the chance has eagerly accepted the invitation. Mainly because the enlightened Empire lets the planetary government continue to rule and do whatever it wants...with a few minor restrictions of course; and because the they are shown what happens to planets who decide not to accept the invitation...

A very wise physician has said that “every illness has two parts—what it is, and what the patient thinks about it.” What the patient thinks about it is often more important and more troublesome than the real disease. What the patient thinks of life, what life means to him is also of great importance and may be the bar that shuts out all real health and happiness. The following pages are devoted to certain ideals of life which I would like to give to my patients, the long-time patients who have especially fallen to my lot.

The human race has reached the stars, colonized many planets and done amazing things in all areas of scientific progress. But humans are still humans and remain both honorable and not so honorable; some with high ideals and others with very low ones indeed. So why hasn't war occurred in several centuries among the hundreds of planets? Has man really changed? Not on your life it hasn't! Read how science has given man peace but at what cost?

Uncontrolled, terribly violent Atomic Vortices are slowly destroying civilization on every human planet throughout the galaxy. Nothing can contain or stop them despite the lensmen's best efforts until one destroys the home and family of "Storm" Cloud, brilliant atomic physicist. The tragedy triggers actions on his part that pit him one-on-one against the horrible vortices. Introducing "storm" Cloud as THE Vortex Blaster

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.

Lee Anthony finds himself and two of his friends kidnapped and taken on a strange voyage.

On the Heavens (Greek: Περί ουρανού, Latin: De Caelo or De Caelo et Mundo) is Aristotle's chief cosmological treatise. In it Aristotle argues that the Earth is a sphere by pointing to the evidence of lunar eclipses. Aristotle also provides a detailed explanation of his theory of 'gravity' arguing that things which contain 'earth' fall towards the centre of the Universe because 'earth' is naturally attracted to the centre of the Universe. Aristotle argues that if the planet Earth was moved to the location of the Moon then objects which contain 'earth' would not fall towards the centre of the Earth but rather towards the centre of the Universe...

Can a spaceship go crazy? Well, yes it can if it has a brain. And the new MG (magnetogravitic drive) experimental robot space ship does indeed have a 'brain'. Completely bewildered as to why the first six models of their supposedly perfect new ship model, the MG-YR, nicknamed the McGuire, have gone totally bonkers after activation and before they could ever be used, the company has called in the services of Daniel Oak. They suspect sabotage of course. Daniel Oak is the hard boiled private investigator with nerves of steel and a mind of the same substance...

On Generation and Corruption (Ancient Greek: Περὶ γενέσεως καὶ φθορᾶς, Latin: De Generatione et Corruptione, also known as On Coming to Be and Passing Away) is a treatise by Aristotle. Like many of his texts, it is both scientific and philosophic (although not necessarily scientific in the modern sense). The philosophy, though, is essentially empirical; as in all Aristotle's works, the deductions made about the unexperienced and unobservable are based on observations and real experiences...

Elisha Gray was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois and is considered by some writers to be the true inventor of the variable resistance telephone, despite losing out to Alexander Graham Bell for the telephone patent.Nature’s Miracles: Familiar Talks on Science, published in 1900, is a discussion of science and technology for the general public. Volume II is subtitled Energy and Vibration: Energy, Sound, Heat, Light, Explosives.

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.

This book, written in the mid 19th century and illustrated by Charles H. Bennett, provides an entertaining introduction to topics in science for children. In each chapter, the author uses a popular myth or fairy tale to lay the groundwork for an equally fascinating "fairy tale of science" full of interesting facts and real life examples.
