The evolution of science through the ages has often been marred by people's misconceptions. From pre-historic times, when myths played a major role in people's lives, to present-day debates concerning the environment, people have sought ways to explain the world around them and have often come up with incorrect answers. Science has grown through the correction of these misconceptions. This unique reference source can be used by students, teachers, and other interested researchers to explore this growth as it pertains to both the field of science and the process of scientific experimentation. Readers will discover how misunderstandings led to further experimentation and eventually to scientific facts.These false paths to scientific knowledge are not treated as deliberate misconduct, but rather as a lack of knowledge and a misunderstanding of the science and technology involved, both of which were sooner or later corrected by men and women of science. Krebs explores the conception and development of scientific thought in five different fields: Medicine and Health, Life Science, Chemistry and Physics, Astrology, Astronomy, and Cosmology, and Conservation, Ecology, and Environmentalism. Within each of these categories, he explores more specific areas, such as the circulatory system, geology, and inner planets. This arrangement provides easy access for the researcher interested in a particular area of science as well as those looking for general information, illuminating how our modern understanding of science is based on much of the developments in our ancient past.
