The extraordinary, unlikely tale of Tycho Brahe and Johannes Kepler and their enormous contribution to astronomy and understanding of the cosmos is one of the strangest stories in the history of science. Kepler was a poor, devoutly religious teacher with a genius for mathematics. Brahe was an arrogant, extravagant aristocrat who possessed the finest astronomical instruments and observations of the time, before the telescope. Both espoused theories that seem off-the-wall to modern minds, but their fateful meeting in Prague in 1600 was to change the future of science. Set in one of the most turbulent and colourful eras in European history, when medieval was giving way to modern, Tycho and Kepler is a double biography of these two remarkable men.

Ferguson's flexible and useful INTRODUCTORY ASTRONOMY EXERCISES, Second Edition, provides professors and students with laboratory exercises that are well-tested, current, and flexible to individual course needs. These labs have a variety of origins and authors, and bring a broad range of activity to the introductory astronomy lab. Most require only inexpensive equipment. INTRODUCTORY ASTRONOMY EXERCISES, Second Edition, gives students practical experience with the things they only read about in their book, such as using a telescope and CCD photography. Ferguson groups the exercises together by whether they deal with the solar system or stars and other objects beyond the solar system. Three introductory exercises on using telescopes, viewing constellations and the Celestial Sphere, and using numbers in science set the stage and help readers overcome anxiety. A combination of indoor and outdoor labs allows for adjustments due to weather conditions. A chart that cross-references exercises in this manual to relevant chapters in Brooks/Cole astronomy books adds to the book's flexibility, and help the instructor reinforce selected topics.
