With over 300 entries from the ancient abacus to X-ray diffraction, as represented by a ca. 1900 photo of an X- ray machine as well as the latest research into filmless x- ray systems, this tour of the history of scientific instruments in multiple disciplines provides context and a bibliography for each entry. Newer conceptions of "instrument" include organisms widely used in research: e.g. the mouse, drosophila, and E. coli. Bandw photographs and diagrams showcase more traditional instruments from The Science Museum, London, and the Smithsonian's National Museum of American History.

Humanity's first contact with alien life is no less than a nightmare, as the Ahimsa take control of Earth and force humanity to do their bidding. Soon, Earth's most skilled strike force, composed of Russian, American, and Israeli experts in the art of war and espionage, find themselves aboard the Ahimsa vessel, training for an offensive attack against a distant space station. And as they struggle to overcome their own prejudices while preparing to face an enemy of unknown capabilities, none of them realize that the greatest danger to humanity's future is right in their midst....

In the first book in the epic Lamb among the Stars series, author Chris Walley weaves the worlds of science and the spirit, technology and supernatural into something unique in science fiction. Twelve thousand years into the future, the human race has spread across the galaxy to hundreds of terraformed worlds. The effects of the Fall have been diminished by the Great Intervention, and peace and contentment reign under the gentle rule of the Assembly. But suddenly, almost imperceptibly, things begin to change. On the remotest planet of Farholme, Forester Merral D’Avanos hears one simple . . . lie. Slowly a handful of men and women begin to realize that evil has returned and must be fought. What will this mean for a people to whom war and evil are ancient history? Thus begins the epic that has been described as “If C. S. Lewis and Tolkien had written Star Wars.” The Shadow and Night was previously published in two volumes: The Shadow at Evening and The Power of the Night.

This remarkable history encompasses not only the achievements of the early inventors and astronomers but also the less frequently recounted stories of the instrument makers and of the actual instruments. A model of unsurpassed, comprehensive scholarship, this volume covers many fields, including professional and amateur astronomy. 196 black-and-white illustrations.

The fourth novel in the Cahokian story cycle, Star Path is an evocative tale about America’s greatest pre-Columbian city by New York Times bestselling authors W. Michael and Kathleen O’Neal Gear How do you say no to a god? Cahokia recovers from a year of chaos following a near civil war and the god incarnate, Morning Star, has declared that his human sister Night Shadow Star and her slave Fire Cat must make a dangerous journey to far off Cofitachequi. For an old threat has arisen on the other side of the great eastern mountains - their brother, Walking Smoke, a madman who is convinced that he is the true deity destined to rule Cahokia. Night Shadow Star is also ruled by the Underworld Lord, Piasa, but this power dangles a chance of happiness in front of Night Shadow Star and Fire Cat – if they succeed with his agenda, they might become nameless, clanless, and worthless. And thus free. But the treacherous Tenasee River that they must travel holds its own perils. And at the end of the journey, Walking Smoke prepares to spring his trap. Star Path, the fourth book in the Gears’ People of Cahokia series, takes the reader out of the great city of Cahokia and into a land of rivers, forests, tribes, and exiled colonies, providing us with a rare look into the mystical underpinnings of Native American culture and the founding of Mississippian civilization.
