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.

“I went to the woods because I wished to live deliberately.” And so it began. Henry David Thoreau, at 27, built a tiny, one-room cabin in the woods — on land owned by his friend, Ralph Waldo Emerson — and began his two-year experiment in frugality on the shore of Walden Pond. He wasn’t seeking isolation so much as simplicity, to “live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms.”

Peter Rabbit would like to know more about the four-footed friends who share the Green Meadows and Green Forest with him. Old Mother Nature is only too happy to help and holds a "school" for Peter. Along the way, many others of the Green Meadow and Green Forest creatures join Peter at school as he learns about his neighbors. As with all Thornton W. Burgess stories, young listeners gain positive values while learning a great deal about the animals that share their world.

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.

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.

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.

In the summer of 1870, Professor Joseph LeConte (1823-1901), and some of his students at the then brand-new University of California, went on a five-week camping trip on horseback to Yosemite and the High Sierra, including Mono Lake and Lake Tahoe. Along the way, LeConte and his students faced hardships of weather and terrain. They had difficulties with their horses and finding trails, and the weather made the men broil and freeze. But in spite all of the harsh conditions, LeConte was enraptured by the awesome beauty of Yosemite Valley, the High Sierra, and Lake Tahoe.  

The so-called "Bigfoot Bible". Ivan T. Sanderson, cryptozoologist (he coined the term) and paranormal and nature writer, methodically examines the wealth of reported sightings and evidence pertaining to the infamous hairy creatures that have been called names like Sasquatch, Yeti and Oh-Mah. This production focuses on the original work's North American material. Originally published by Chilton Company in Philadelphia in 1961. 

Charlie's Mailbox is a lyrical and poetic tale told through the eyes of Charlie, a lonely girl who stumbles upon an old mailbox and the power of dreams.

The Burgess Bird Book for Children introduces children to the fascinating subject of bird life in storybook fashion. Thornton Burgess uses Peter Rabbit as a means for younger children to learn about birds in the Green Forest and Green Meadows. On the journey through the book, Peter learns a great deal from sassy Jenny Wren and other neighbors. Listeners learn about common birds' physical appearance, eating, nesting habits, and songs and calls.

“In wildness is the preservation of the world.” Here are three of Thoreau’s most famous talks brought together in one volume. “Walking,” “Autumnal Tints,” and “Wild Apples” are all autumn essays—contemplative, deliberate, and insightful. They are profound reflections on nature, beauty, and our place in the world. In 1862, during Thoreau’s last weeks, he received a request from The Atlantic Monthly’s new editor, James Fields, to submit some of his work. These three were all published that year, after his death
