This title provides a thorough discussion of the most important scientific principles, laws and theories, along with their everyday uses. What's a scientific theory? How is it different from a law or a principle? And what practical use are they? Science students ask these questions everyday about these essential parts of a science education. "The Encyclopedia of Scientific Principles, Laws, and Theories" is designed to be an easy-to-understand, accessible, and accurate description of the most famous scientific concepts, principles, laws, and theories that are known in the areas of astronomy, biology, chemistry, geology, mathematics, medicine, meteorology, and physics. This title provides a comprehensive but not overwhelming source of those scientific concepts, principles, laws and theories that impact every facet of our daily lives."The Encyclopedia of Scientific Principles, Laws, and Theories" includes several hundred entries. For ease of use, entries are arranged alphabetically by the names of the men or women who are best-known for their discovery or development or after whom the particular scientific law or theory is named. Entries include: Calvin's Carbon Cycle; Clausius' Laws and Theory of Thermodynamics; Dicke's Theory of the Big Bang; Gilbert's Theory of Magnetism; Lysenko's Theory of the Inheritance of Acquired Characteristics; and Mohorovicic's Theory of the Earth's Interior Structure.Entries include a short biography of the main discoverers, as well as any information that was of particular relevance in the evolution of the scientific topic. This set also offers examples of the usefulness of the theories, principles, and laws in everyday life, demonstrating that understanding these concepts have practical use. This title discusses the everyday applications of scientific theories, laws and principles. Entries include resources for further research. It contains a general bibliography of particularly useful primary and secondary sources.
