Published in 1920, Slosson’s Easy Lessons in Einstein is one of the first popularizations of Einstein’s theory of relativity. This book is meant to convey to the general reader the ideas of relativity in non-mathematical terms, by the use of thought experiements and pop-cultural references of the day. This edition also includes a short article by Einstein on Time, Space and Gravitation.

Delightful sketches of British wild birds – a bird for every month of the year from the pheasant in January to the robin in December. This collection of articles, reprinted in book form from the periodical The Outlook, is full of fascinating information about bird behaviour and habitat, as well as many interesting anecdotes. Out of date in some respects, particularly in its reference to the (now illegal) collecting of birds’ eggs, this book brings home forcefully how the populations of some British wild birds have declined since it was written.

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...

Elisha Gray (August 2, 1835 – January 21, 1901) 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.

Katharine E. Dopp was well-known as a teacher and writer of children’s textbooks at the turn of the 20th Century. She was among the first educators to encourage the incorporation of physical and practical activity into the elementary school curriculum at a time when such activities were becoming less commonplace in a child’s home environment. The Tree-Dwellers – The Age of Fear is the first in a series of elementary school texts written by Ms. Dopp that focus on the anthropological development of early human groups...

"Naturalis Historia" (Latin for "Natural History") is an encyclopedia published circa AD 77-79 by Pliny the Elder. It is one of the largest single works to have survived from the Roman empire to the modern day and purports to cover the entire field of ancient knowledge, based on the best authorities available to Pliny. The work became a model for all later encyclopedias in terms of the breadth of subject matter examined, the need to reference original authors, and a comprehensive index list of the contents...

The Chemical History of a Candle is a series of 6 lectures on chemistry presented to a juvenile audience in 1848. Taught by Michael Faraday - a chemist and physist, and regarded as the best experimentalist in the history of science - it is probably the most famous of the Christmas Lectures of the Royal Society. Taking the everyday burning of a candle as a starting point, Faraday spans the arc from combustion and its products, via the components of water and air (oxygen, hydrogen, nitrogen, carbon), back to the type of combustion that happens in the human body when we breathe...

Robert Sterling Yard (February 1, 1861 – May 17, 1945) was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916...

Alaska has only been a state since 1959, and the breathtaking terrain remains mostly unspoiled and natural. In modern times, many of us have had the pleasure of visiting Alaska via a luxurious cruise ship, where we enjoyed gourmet meals, amazing entertainment, and a climate-controlled environment. It's easy to also book a land package that enables you to see more of the country by train.Imagine what it was like to visit the same wild, untamed countryside in 1899. Instead of boarding a sleek, stylish cruise ship, you travel for weeks on a steamer...

This is a series of late-19th Century essays about Florida’s flora & fauna written by a Massachusetts-based naturalist.

James Thomas Fields was an American publisher, editor, and poet. At the age of 14, Fields took a job at the Old Corner Bookstore in Boston. His first published poetry was included in the Portsmouth Journal in 1837 but he drew more attention when, on September 13, 1838, he delivered his “Anniversary Poem” to the Boston Mercantile Library Association.

The Land of Little Rain is a book of sketches which portray the high desert country of southern California, where the Sierras descend into the Mojave Desert. Mary Austin finds beauty in the harsh landscape: "This is the sense of the desert hills--that there is room enough and time enough. . . The treeless spaces uncramp the soul." Her story begins with the water trails that lead toward the few life giving springs--the way marked for men by ancient Indian pictographs. Life and death play out at these springs...

Gregor Mendel (1822 - 1884) was an Augustinian monk in the St. Thomas monastery in Brno. His seminal paper "Experiments on Plant Hybridization" presents his results of studying genetic traits in pea plants. It is the ground breaking work on inheritance, being the first to differentiate between dominant and recessive genetic traits. His work was long ignored and deemed controversial, however, at its rediscovery at the turn to the 20th century, it earned Gregor Mendel the title "father of modern genetics".

Isabella L. Bird was an English traveller, writer and natural historian. She was travelling in the Far East alone at a time when such endeavours were risky and dangerous even for men and large, better equipped parties. In "Among the Tibetans", Bird describes her tour through Tibet with her usual keen eye: From descriptions of the landscape and flora to the manners, customs and religion of the local people we get a fascinating account of a world long past.

Bud Sloan was an orphan who had been 'sold out' of the orphanage to work on a farm once he'd been old enough to labor. The farm where he was to work was owned by an aging farmer and his wife who had raised a large family and were now left alone. One day, after his chores were done, Bud wandered into the woods nearby and with mouth agape, he noticed a newborn jet black fawn all alone and apparently confused in his new surroundings. Bud resolved that day that this baby fawn was just like himself, an orphan, and would be bound to him in spirit...

The Englishman Harrison Weir organized the first cat show in England in 1871. In 1887 he founded the National Cat Club and was its first President and Show Manager until his resignation in 1890.Our Cats and all about them is concerned with cats and all about them. It describes numerous breeds of cats and what to look for in a cat show champion, and deals with the general management and common diseases of cats, as well as how to raise healthy kittens.

This is a book of myths told by the Indians of North America to their children. They could be compared to present day Fairy Tales.

Treatise on Light was published in 1690 and is probably the largest scientific volume on light published before Newton's Opticks. The book explains how light travels (i.e., that it has a certain velocity), and what happens when it hits a surface (refraction and reflection). A large portion of the book is devoted to the double refraction occurring in Iceland chrystal, and all drawn conclusions are proved geometrically. Christiaan Huygens (1629 - 1695) was a prominent physicist and astronomer. His main discoveries are the centrifugal force, collision laws for bodies and the argument that light consists of waves...

Prof. Hiram Bingham of Yale Makes the Greatest Archaeological Discovery of the Age by Locating and Excavating Ruins of Machu Picchu on a Peak in the Andes of Peru.There is nothing new under the sun, they say. That is only relatively true. Just now, when we thought there was practically no portion of the earth's surface still unknown, when the discovery of a single lake or mountain, or the charting of a remote strip of coast line was enough to give a man fame as an explorer, one member of the daredevil explorers' craft has "struck it rich...

Florence Augusta Merriam Bailey (August 8, 1863 - September 22, 1948) was an American ornithologist and nature writer. She started observing bird behavior at a time when most bird study was based on collections and skins. By 1885, she began to write articles focusing on protecting birds. Her introduction of a birdwatching field guide, aimed at living birds, is considered the first in the tradition of modern bird guides. She wrote the first of these at the age of 26, initially as a series of notes in the Audubon Magazine and later as books. In "A-Birding on a Bronco," she writes an engaging memoir about her several trips to study birds on a ranch in California in the late 1800's.

In this work Levison aims to create a book that allows beginners to be able to understand how to identify trees, as well as to give information of their structure and uses. Once these topics are addressed, he then moves into concepts of care, planting and forestry.

The Art of Travel is a handbook of practical advice for the adventure seeking Victorian. We hear how to organize all steps of a voyage, from the very beginnings (qualifications of a traveller, how to organize an expedition, the perfect outfit), to the actual trip (how to choose a bivouac, huts and tents, what game to shoot - and how, dealing with (hostile) savages), until the final, hopefully successful, return of the traveller (arranging memoranda).

This book, with the subtitle "Across the Continent of South America" describes the scientific expedion of 1867 to the equatorial Andes and the Amazon. The route was from Guayaquil to Quito, over the Cordillera, through the forest to Napo, and, finally, on the Rio Napo to Pebas on the Maranon. Besides this record, the expedition - under the auspices of the Smithsonian Institute - collected samples of rocks and plants, and numerous specimen of animals. The scientists also compiled a vocabulary of local languages and produced a new map of equatorial America...

Josephine Preston Peabody was an American poet and dramatist. She was born in New York and educated at the Girls’ Latin School, Boston, and at Radcliffe College.

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.
