Logic and Deduction differs from other titles and offers fresh viewpoints and suggestions for more effective and better utilization of logic in the sciences and mathematics, such as theoretical physics, number theory, sociology, and economics. Much of the title touches on scientific and mathematical topics, e.g., mathematical proof, Godel's incompleteness theorems, set theory, infinity, the work of well-known logicians such as Frege and Russell, calculus, relativity, quantum theory, chaos, unified field theory, speed of light, gravity, etc., including the soft sciences such as economics and sociology. The coverage is comprehensive, as logic applies not only to the hard sciences but also to the soft sciences. The book could be useful to scholars, researchers, students of the hard and soft sciences, intellectuals, professionals such as physicists working on unified field theory & mathematicians working on number theory, logicians, philosophers, lawyers arguing criminal law cases, writers, economists, sociologists, government bureaucrats & policy-makers, corporate executives, activists aiming for a better society, and anyone keen on increasing brainpower or mind-expansion. It could inspire and spur further thought on logic.
