A revised edition of a classic guide to woodworking methods that have been refined and developed over thousands of years. It teaches and preserves techniques and historical information that were lost when modern woodworking technology, dedicated to mass production, displaced the craftsman. Every woodworking operationâ?¬â? chopping, splitting, using the workbench, sawing, hewing, boring, chiseling, shaping, planing, turningâ?¬â? is described in detail. There is also information on the role of various tools in the evolution of wood products, the types and characteristics of wood, the preparation and maintenance of tools, collective tools of antique value, and instruction on the subtleties of the craft, from rabbeting to molding. The professional woodworker, the hobbyist, the collector, the antiques dealer, and the craft enthusiast will discover valuable information in this definitive work. It is reference, guide, and history all in one volume.This book contains over 200 line drawings by the author to illustrate age-old, yet fascinating, ways of working with wood. With chapters that describe the ways to fell a tree, methods for splitting wood, and more, along with a complete appendix and index, this is a great reference for anyone interested in the ways of wood working.
If you understand basic mathematics and know how to program with Python, you’re ready to dive into signal processing. While most resources start with theory to teach this complex subject, this practical book introduces techniques by showing you how they’re applied in the real world. In the first chapter alone, you’ll be able to decompose a sound into its harmonics, modify the harmonics, and generate new sounds. Author Allen Downey explains techniques such as spectral decomposition, filtering, convolution, and the Fast Fourier Transform. This book also provides exercises and code examples to help you understand the material. You’ll explore: Periodic signals and their spectrums Harmonic structure of simple waveforms Chirps and other sounds whose spectrum changes over time Noise signals and natural sources of noise The autocorrelation function for estimating pitch The discrete cosine transform (DCT) for compression The Fast Fourier Transform for spectral analysis Relating operations in time to filters in the frequency domain Linear time-invariant (LTI) system theory Amplitude modulation (AM) used in radio Other books in this series include Think Stats and Think Bayes, also by Allen Downey.
Includes information on the discovery of gold in California, the Pony Express, missions and missionaries in California, stagecoaches, transcontinental railroad, etc.
