All geologists need a grasp on basic physics, and in plain language using simple mathematics, this book provides the understanding they need. It discusses a wide range of forces at work in geology against the background of Kepler's and Newton's laws; electromagnetic radiation, atomic structure, and age-dating. Other topics include. electromagnetic radiation, atomic structure and age-dating, heat and heat flow, electricity and magnetism, stress and strain, sea waves, acoustics, and fluids and fluid flow. The book includes basic definitions and dimensions and also some warnings about misunderstanding mathematical statistics, particularly of linear regression analysis, and unenlightened computation.
