The ABC of Relativity is still considered today, nearly 90 years after its first appearance, as an authoritative and accessible introduction to Einstein's Theory of Relativity. While there's nothing particularly easy about understanding the Theory of Relativity, many have found that Russell's explanation is easier to understand than Einstein's own writings on the topic. Russell covers topics such as time dilation and curved space-time, using non-scientific examples of train travel and aerial views of the terrain.

July 1967: At the Moscow Air Show, the Soviets unveiled six new state-of-the-art aircraft. From among this lineup of new fighters and interceptors stood the Mikoyan-Gurevich MiG-25 - purportedly capable of outrunning and outmaneuvering any aircraft in NATO’s inventory. Yet even before its public appearance in Moscow, the MiG-25 had been a grave concern for Western analysts.

“In wildness is the preservation of the world.” Here are three of Thoreau’s most famous lectures brought together in one volume. “Walking,” “Autumnal Tints,” and “Wild Apples” are all autumn essays—contemplative, deliberate, and insightful. They are profound reflections on...

Here, it was almost inevitable that this subject would attract the interest of H.G Wells in the batch of sci-fi novels that he wrote between 1895 and 1901. In Well's story, the vehicle is not a balloon, as in many of the previous accounts, but a sphere made of a mysterious substance, named "cavorite" after its inventor, Cavor, who accompanies the narrator, Bedford, on the trek to the moon. The ascent is made possible by the fact the "cavorite" is, in Well's words, "transparent to gravity."

Compounding the problem is a fuel leak from underground tanks threatening to detonate. Two Colonial Survey troubleshooters have been called to the planet to try and rectify the situation.

Along the way, Burgess characters, including the Merry Little Breezes, Grandfather Frog, and others, help Peter find new flowers as they bloom. The description of the flowers is very detailed.

The environment and its decline in health is the most important issue facing mankind today and is a subject everyone should have an understanding of, from business CEOs to the average person in society. By exploring topics such as biodiversity, ecosystem services, sustainability, and ecology, the listener will be equipped with the necessary foundational knowledge that is required before effective management strategies can be considered and implemented, either in business or at the home.

This is the optimistic story of our fraught relationship to universal consciousness, the domain that transcends every local mind. It is also the story of how reality is relative and changeable to the way each of us makes meaning. Truth, on the other hand, represents the permanent and timeless state of being beyond history and culture that is called nonlocal universal consciousness. This is the state of nonpersonal awareness within insight and eyesight.

This infamous compendium of the strange and unexplained, including UFOs and strange weather, was the result of decades of research in libraries by its author, Charles Fort (the inspiration for the term "Fortean"). Worldwide occurrences of the supernatural and the paranormal are documented, with names and pages of sources provided.

A poke at idioms, sci-fi style. If we read everything literally, we'd go mad.

Henry David Thoreau discusses walking, the importance of nature, and the human need for walking in the wilderness.

Jolly Robin is a happy go lucky bird. He does tend, however, to stick his nose into other animals' business and believes that perhaps, they should sing or act like him.

Since many things in the world are new to him, he also sometimes makes and spreads mistakes to his acquaintances with some unpredictable events.

A four-star general pays tribute to a remarkable man in this biography. Believing that America owes a debt to a great character, a superb aviator, and a devoted citizen that was not paid, General Kenney tells the story of Paul Irvin "Pappy" Gunn with the hope that it will help discharge some of that debt. Gunn, who was known during World War II as an expert in daredevil low-level flying and as a hero and mechanical genius, modified light and medium bombers and transformed them into attack aircraft to hit Japanese targets in New Guinea, the Philippines, and Okinawa.

In 1966, Isaac Asimov and Theodosius Dobzhansky wrote The Genetic Effects of Radiation as a public information resource for the US Atomic Energy Commission. In Asimov's typically incisive and easy-to-understand style, the pair presents an overview of genetics, and how inherited traits can be influenced by external factors, including radiation, both environmental and man-made.

In this 1972 treatise, Isaac Asimov takes the listener on an historic journey through the development of man's understanding of electricity, chemistry, and - ultimately - nuclear energy. Asimov's incomparable ability to simplify the complex is apparent as he guides you through the milestones of scientific thought that connected ideas about electricity and magnetism to the nature of matter, and led to the advances in discovery through the first half of the 20th century that resulted in the harnessing of previously unknown energy directly from the heart of the atom.

For centuries, Newton's doctrine of the attraction of gravitation had been the most prominent example of a theory of natural science. However, as with many successful theories, there were some anomalies it could not explain. In his attempts to address these problems, Einstein developed a radical and equally influential theory, that of relativity. This essay is a classic exposition of the basic elements of Einstein's theory by his Dutch colleague, Professor H.A. Lorentz.
