Nonlinear Estimation and Applications to Industrial Systems Control [PDF ebook] 

This book reexamines conservatism, the dominant ideology, politics, and discourse in America since the 1980s through the 2010s. This book investigates and uncovers what conservatism has so successfully and cleverly kept as its best secret and mystery, its initial roots and its ultimate outcome, especially in America in contrast to Europe where it has not been so successful in this respect. This book rediscovers the point of origin or genesis and the destination or end point of conservatism. It reveals medievalism, including feudalism, despotism, and medieval theocracy, as the point of origin, "golden past" of conservatism. It diagnoses and anticipates fascism, including Nazism and neo-fascism, as the destination, "bright’ future of conservatism. This book exposes conservatism as the "child" of the Dark Middle Ages and the "parent" of fascism as the "New Dark Ages." By uncovering its long journey from medievalism to fascism the book renders conservatism’s best kept secret into the worst kept.
