Doubleday chronicles the history of everyday inventions that form the foundation of technology now common through the world. While some of the inventions are no longer used, each example shows how inventors contributed to technology through perseverance, inspiration and clever observations. In each chapter, he gives a clear, understandable background of the technology. Many of the now outdated inventions may have inspired later inventions by meeting emerging demands. For example, Edison's filament bulb is now being phased out by more efficient CFL's, but Edison's contribution to indoor lighting likewise removed the need for inefficient gas-burning lamps. While trains for carrying mail and freight have largely been replaced by more nimble semi trailers, one example shows how technology can translate from ground to air travel. Trains with curved pipes that scooped water to refill reservoirs could be controlled from the train engine-cab without stopping, and mirrors the in-flight refueling systems that keep aircraft flying without the need to land. Although computers have replaced typewriters, word processing programs and web browsers ...

Science Fiction is speculative literature that generally explores the consequences of ideas which are roughly consistent with nature and scientific method, but are not facts of the author’s contemporary world. The stories often represent philosophical thought experiments presented in entertaining ways. Protagonists typically “think” rather than “shoot” their way out of problems, but the definition is flexible because there are no limits on an author’s imagination. The reader-selected stories presented here were written prior to 1962 and became US public domain texts when their copyrights expired. (Summary by Gregg Margarite)...

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. The final lecture On Platinum describes a then new method to produce large quantities of Platinum. It was delivered before the Royal Institution on February 22, 1861. (Summary by Availle.)...

The Monadology ( La Monadologie , 1714) is one of Gottfried Leibniz’s best known works representing his later philosophy. It is a short text which sketches in some 90 paragraphs a metaphysics of simple substances, or monads. What he proposed can be seen as a modification of occasionalism developed by latter-day Cartesians. Leibniz surmised that there are indefinitely many substances individually 'programmed' to act in a predetermined way, each program being coordinated with all the others. This is the pre-established harmony which solved the mind body problem at the cost of declaring any interaction between substances a mere appearance, something which Leibniz accepted. Indeed it was space itself which became an appearance as in his system there was no need for distinguishing inside from outside. True substances were explained as metaphysical points which, Leibniz asserted, are both real and exact — mathematical points being exact but not real and physical ones being real but not exact.

In The Concept of Nature , Alfred North Whitehead discusses the interrelatedness of time, space, and human perception. The idea of objects as 'occasions of experience', arguments against body-mind duality and the search for an all-encompassing 'philosophy of nature' are examined, with specific reference to contemporary (Einstein, with whose theory of relativity he has some complaints) and ancient (Plato, Aristotle) approaches.

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. (Summary by Availle)...

Teenagers Peggy Prescott and her brother Roy share a love of aviation that they inherited from their late father. Mr. Prescott had always dreamed of building an aeroplane that would be free of the defects of planes already invented. Peggy and Roy manage to build a plane starting with the framework their father had begun. Peggy christens it ‘The Golden Buttefly’ and she and Roy are determined to enter it in a young aviator’s contest for a prize of $5000. The Prescotts need the money desperately to save the home they share with their aunt which is about to be taken from them by the rather nasty banker, Mr. Harding. Peggy and Roy along with their best friends, Jess and Jimsy Bancroft – also sister and brother, experience many adventures – many of them while flying the Golden Butterfly. A kidnapping, missing jewels and contact with some desperate characters are just some of what the Prescotts encounter in their Long Island village of Sandy Bay. There’s never a dull moment for these two as they pursue their dream of flying. (Summary by Lee Ann Howlett.)...

Dr. Walsh's Old-Time Makers of Medicine chronicles the history and development of modern medicine from ancient times up to the discovery of America. Throughout this historical guide, Dr. Walsh shows numerous examples of practices thought to be entirely modern that were clearly anticipated hundreds or thousands of years ago. Ancient healers sought to use the body's natural healing ability, rather than rely exclusively on external cures. Physicians even in ancient times relied on what is now recognized as the placebo effect. Dr. Walsh also addresses training and certification in medicine. Medieval universities anticipate our modern medical textbooks with consolidated records of all research and independent investigations, to provide uniform training for students. Likewise, the reader will find that the ancients reacted to unsuccessful treatment in similar degrees to what might now be called medical malpractice suits. The book is organized chronologically, beginning with the fall of the Roman Empire and growth of the early Christian Church. From there, Dr. Walsh details the development of medical knowledge and practice in Arabia, to Me...
