Elements

Euclid was a mathematician from the Greek city of Alexandria who lived during the 4th and 3rd century B.C. and is often referred to as the "father of geometry." Within his foundational treatise "Elements," Euclid presents the results of earlier mathematicians and includes many of his own theories in a systematic, concise book that utilized a brief set of axioms and meticulous proofs to solidify his deductions. In addition to its easily referenced geometry, "Elements" also includes number theory and other mathematical considerations. For centuries, this work was a primary textbook of mathematics, containing the only framework for geometry known by mathematicians until the development of "non-Euclidian" geometry in the late 19th century. The extent to which Euclid's "Elements" is of his own original authorship or borrowed from previous scholars is unknown, however despite this fact it was his collation of these basic mathematical principles for which most of the world would come to the study of geometry. Today, Euclid's "Elements" is acknowledged as one of the most influential mathematical texts in history. This volume includes all thirteen books of Euclid's "Elements," is printed on premium acid-free paper, and follows the translation of Thomas Heath.

The Periodic Table Book is the perfect visual guide to the chemical elements that make up our world. This eye-catching encyclopedia takes children on a visual tour of the 118 chemical elements of the periodic table, from argon to zinc. It explores the naturally occurring elements, as well as the man-made ones, and explains their properties and atomic structures. Using more than 1,000 full-colour photographs, The Periodic Table Book shows the many natural forms of each element, as well as a wide range of both everyday and unexpected objects in which it is found, making each element relevant for the child's world.

A fun, fascinating, and amazingly photographic exploration of the periodic table, for curious kids who want to understand how atoms and elements make up everything in the universe.

When was radium discovered? Who are Dmitri Mendeleev and Glenn T. Seaborg? Who discovered uranium's radioactivity? Which element is useful for dating the age of Earth? And why doesn't gold have a scientific name? 30-Second Elements presents you with the very foundations of chemical knowledge, explaining concisely the 50 most significant chemical elements. This book uses helpful glossaries and tables to fast track your knowledge of the other 68 elements and the relationships between all of them.

This book breaks new ground by doing something for digital photographers that’s never been done before—it cuts through the bull and shows you exactly “how to do it.” It’s not a bunch of theory; it doesn’t challenge you to come up with your own settings or figure things out on your own. Instead, it does something that virtually no other Elements book has ever done—it tells you flat-out which settings to use, when to use them, and why. If you’re looking for one of those “tell-me-everything-about-the-Unsharp-Mask-filter” books, this isn’t it. You can grab any other Elements book on the shelf, because they all do that. Instead, this book gives you the inside tips and tricks of the trade for organizing, correcting, editing, sharpening, retouching, and printing your photos like a pro. You’ll be absolutely amazed at how easy and effective these techniques are—once you know the secrets. LEARN HOW THE PROS DO IT Each year we train thousands of digital photographers and, almost without exception, they have the same questions and face the same problems—that’s exactly what we cover in this book. You’ll learn: The real secrets of how the pros retouch portraits How to color correct any photo without breaking a sweat (you’ll be amazed at how the pros do it!) How to use Camera Raw for processing not only RAW photos, but JPEGs and TIFFs, too! (And you’ll learn why so many pros like it best—because it’s faster and easier) The sharpening techniques the pros really use (there’s an entire chapter just on this!) How to deal with common digital camera image problems, including removing noise and avoiding halos The most requested photographic special effects, and much more! THE BOOK’S SECRET WEAPON Although Elements 10 offers some digital photography features that Photoshop CS5 doesn’t offer, there are plenty of features that Photoshop CS5 has that Elements 10 still doesn’t have (things like paths, Channel Mixer, etc.). But in this book, you’ll learn some slick workarounds, cheats, and some fairly ingenious ways to replicate many of those Photoshop features from right within Elements. Plus, since this book is designed for photographers, it doesn’t waste your time talking about how to frame a shot, set your exposure, etc., and there’s no talk about which camera or printer to buy. It’s all Elements, step by step, cover to cover, in the only book of its kind, and you’re gonna love it!
