Available in PDF, EPUB and Kindle. Book excerpt: A hobby backed by centuries of tradition, amateur gem cutting remains popular today. Once a completely unskilled beginner himself, Captain John Sinkankas never forgot his struggles in learning how to cut and polish gemstones without the benefit of an instructor. With his own experience in mind, he wrote "Gem Cutting" to make it possible for others to teach themselves how to do every type of lapidary work without having to attend classes. For over half a century, "Gem Cutting" has served as the go-to guide for beginners and experts alike. Offering a wealth of information for everyone, it starts with the fundamentals and leads logically to techniques and projects that will challenge even the most advanced cutter. Every step is described in detail and illustrated with drawings and photographs. Sinkankas covers common pitfalls and, wherever possible, offers hints on how to take money-saving shortcuts. Incorporating tips on operating equipment for greatest efficiency, he explains how to make or choose equipment for sawing, grinding, sanding, and other basic operations. Special chapters describe how to cut and polish cabochons, faceted gems, spheres and beads; how to tumble gems; and how to make carvings, engravings, inlays, and mosaics. Sinkankas also advises on selecting and buying rough gemstones. A section on the description and treatment of gemstones has been expanded in this second edition to include more species and accommodate recent information on each. With its comprehensive guidance, "Gem Cutting" is an essential addition to the library of any lapidary. Captain John Sinkankas (1915-2002) dedicated his life to the study of earth sciences after his retirement from the US Navy. Winner of the "Desert Magazine" Literature Premium Award, Sinkankas authored a number of books on gemstones and published over 100 articles on lapidary subjects. He was a certified gemologist of the American Gem Society with memberships to the Mineralogical Society of America, New York Mineralogical Club, San Diego Mineral & Gem Society, and several other regional gem and mineral groups.

Download or read book Geocomputation with R written by Robin Lovelace and published by CRC Press. This book was released on 2019-03-22 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geocomputation with R is for people who want to analyze, visualize and model geographic data with open source software. It is based on R, a statistical programming language that has powerful data processing, visualization, and geospatial capabilities. The book equips you with the knowledge and skills to tackle a wide range of issues manifested in geographic data, including those with scientific, societal, and environmental implications. This book will interest people from many backgrounds, especially Geographic Information Systems (GIS) users interested in applying their domain-specific knowledge in a powerful open source language for data science, and R users interested in extending their skills to handle spatial data. The book is divided into three parts: (I) Foundations, aimed at getting you up-to-speed with geographic data in R, (II) extensions, which covers advanced techniques, and (III) applications to real-world problems. The chapters cover progressively more advanced topics, with early chapters providing strong foundations on which the later chapters build. Part I describes the nature of spatial datasets in R and methods for manipulating them. It also covers geographic data import/export and transforming coordinate reference systems. Part II represents methods that build on these foundations. It covers advanced map making (including web mapping), "bridges" to GIS, sharing reproducible code, and how to do cross-validation in the presence of spatial autocorrelation. Part III applies the knowledge gained to tackle real-world problems, including representing and modeling transport systems, finding optimal locations for stores or services, and ecological modeling. Exercises at the end of each chapter give you the skills needed to tackle a range of geospatial problems. Solutions for each chapter and supplementary materials providing extended examples are available at https://geocompr.github.io/geocompkg/articles/. Dr. Robin Lovelace is a University Academic Fellow at the University of Leeds, where he has taught R for geographic research over many years, with a focus on transport systems. Dr. Jakub Nowosad is an Assistant Professor in the Department of Geoinformation at the Adam Mickiewicz University in Poznan, where his focus is on the analysis of large datasets to understand environmental processes. Dr. Jannes Muenchow is a Postdoctoral Researcher in the GIScience Department at the University of Jena, where he develops and teaches a range of geographic methods, with a focus on ecological modeling, statistical geocomputing, and predictive mapping. All three are active developers and work on a number of R packages, including stplanr, sabre, and RQGIS.

Download or read book Handbook for the Amateur Lapidary written by James Harry Howard and published by Ravenio Books. This book was released on 1935 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Man was cutting, carving and polishing gems long before he began to leave written records of his doings. Many Museums have countless examples of the lapidary work done by those artisans and artists, who wrought from raw materials, with exceedingly primitive equipment, objects of art that our modern workers would be hard taxed to surpass. Today, in the Far East, native artisans with hand or foot driven wheels are producing perfect polishes on difficult gems, showing workmanship of which we amateurs with full complement of tools may well be envious. Gem cutting is only one of many arts that are old. Ceramics, wood working, metal working and so forth are old arts. The thing that is peculiar is that these other arts all have their extensive literatures. One may go to any public library and find many volumes on any of these subjects except gem cutting. These volumes are all-revealing, authoritative and detailed. But the subject of gem cutting is shrouded in mystery. Few have written even in generalities on the subject. The Author, several years ago, conducted a search for such literature. He found absolutely nothing. Much later he learned of and borrowed, a copy of Oliver Byrnes, “Handbook for the Mechanic, Artisan and Engineer” and found in it an exceedingly interesting chapter on gem cutting. But the volume was written about 75 years ago, probably had a very limited circulation, was never reprinted, and not one library in fifty ever heard of it. That is the only volume the Author has ever found that treats even briefly of gem cutting. This excludes of course such texts as “The Gem Cutters Craft” by Leopold Cleremont which have chapters on the technique of cutting, but that treat of it so generally that they cannot be used as instructions. The art for some reason has always been passed down from generation to generation by apprenticeship only. When the Author began the above mentioned investigation he was told “The cutting of gems can be learned only through an apprenticeship.” There is no desire here to picture the art as an easy one to learn nor to minimize the skill that is shown by the work of the professional lapidaries, nor to intimate that the professional could, if he would, reveal all his secrets in one brief volume. The desire is to lift the cloud of mystery that has always surrounded the operation and show that actually there is nothing mysterious in the practices of the profession, but only certain basic rules, which, if obeyed, will bring definite results. It is hoped that the instructions herein given are sufficiently explicit that the beginner in the work will have no especial difficulties. It is hoped also that they are not so tedious but that they will be readable by those who do not propose to cut gems but who are, nevertheless, interested in the operation.
